Enough to be useful in two minutes.
#1-1 What LinkMartin does
LinkMartin saves pages and then helps you find them again. Every save keeps the title, the address,
and a picture of the page. With AI switched on, it also writes a short description, adds tags, and sorts
the page into one of your categories — so you can find something six months later without remembering
what you called it.
It stores everything on your device, and it can show your own saved pages next to Google's results
when you search.
#1-2 Install it and save your first page
Install LinkMartin from the Chrome Web Store, then open any page you want to keep and click the
LinkMartin icon beside the address bar. That is the whole save: no account, no folder, no fields to
fill in. The page appears in your library immediately.
Pin the icon if Chrome has tucked it into the extensions menu — the save is one click only if the icon
is visible.
#1-3 What works without an account
Almost everything. Saving, the library, search, sorting, categories, tags you write yourself, the card
in Google, import, export, and your screenshots all work signed out, stored on this device.
An account adds two things: AI descriptions and tags, and sync between the places you
have installed LinkMartin. If you never sign in, nothing you have saved is held back from you.
#1-4 Where everything lives: the panel, the library, the settings
Clicking the icon opens the panel — your library, with search at the top. Switch between a list
and tiles, filter by category or tag, and click a bookmark to open it. The same library is on the web,
signed into the same account, when you want it full-screen.
Open a bookmark and it slides over the library as a single sheet: the picture, the title, when you
saved it and how often you have opened it, its category, its tags, the description, and related
bookmarks. Edit anything there and a Save button appears.
Settings are in the same panel, and they are grouped into cards: Account & Sync, Google results, AI
descriptions and tags, Categories and tags, Appearance, Import and export, and Storage. Section 13 of
this guide describes each one.
Saving pages
#2-1 How to save a page
Click the LinkMartin icon while the page is open. The save happens straight away and is never blocked
— not by a missing account, not by a slow connection, and not by running out of AI credits.
#2-2 What a saved page contains
A title, taken from the page itself. The web address. A picture of the page. The date you saved it. If
AI is on, also a description, tags, and a category.
The title is built from the page's own data, so it is there whether or not you use AI, and whether or
not you are online.
#2-3 Editing anything on a bookmark
Every field is yours to change: title, description, category, and tags. Editing a description the AI
wrote does not cost a credit, and LinkMartin will not overwrite your edit later.
#2-4 Saving the same page twice
LinkMartin checks as you save and tells you the page is already in your library, so you keep one
bookmark instead of four. This check is free, on every plan, always.
#2-5 Deleting a bookmark
Delete it from the bookmark itself in the library. Deleting a bookmark deletes its picture too, and it
cannot be undone.
If you save the same page again later, it comes back as a new bookmark with nothing on it — the
description, tags, and opens from before are gone for good.
Your library
#3-1 List view and tile view
The list shows more bookmarks at once and is easier to scan by title. Tiles show the page pictures,
which is faster when you half-remember what something looked like. Switch at the top of the library;
LinkMartin remembers your choice.
#3-2 Searching your library
Type in the search box. LinkMartin matches the words you type against titles, descriptions, tags,
categories, and web addresses.
It matches words, not meanings, so a search for "cheap flights" will not find a page about "budget
airfare" unless one of those words is in the bookmark. If you cannot find something, try a word that is
likely to be in the title or the address.
#3-3 Sorting
Sort by the date you saved a bookmark, newest or oldest first; by title, A–Z or Z–A; or by when you
last opened it.
#3-4 Filtering by category or tag
Pick a category to see only what is filed there, or a tag to see everything carrying it. Filters
combine with search, so you can search inside a category.
#3-5 Related bookmarks
Open a bookmark and LinkMartin lists others that share words with it, each with a match percentage. It
is a quick way back into a subject you were reading around.
#3-6 Dates and opens: what LinkMartin records
Each bookmark carries the date you saved it, how many times you have opened it, and when you last did.
Opens are counted when you click a bookmark inside LinkMartin — in the library, in a search result, or
on the card in Google. Opening the same page from Chrome's own bookmarks bar is not something
LinkMartin can see, so it is not counted. Imported bookmarks start with no opens and build up a history
as you use them.
Categories
The one part of the product where a user's choice changes how well the AI works.
#4-1 What a category is
A category is a broad bucket you name yourself — Recipes, Client work, Holiday 2027. The AI reads the
name and sorts new saves into it. There is no fixed list to choose from: five categories are set up for
you when you sign up, and you can rename or delete any of them.
The AI never invents a category and never suggests one. It only ever picks from the categories you
have.
#4-2 Naming a category so the AI can use it
Name it for what belongs there — the AI sorts by the name. "Recipes" works, "Stuff" does not.
This is the one place where a name does real work. A vague name gives the AI nothing to match against,
and pages that should have gone there end up Uncategorised instead.
#4-3 Renaming and deleting
Rename a category and new saves follow the new name. Renaming does not re-file what is already in
there, so if you rename Videos to Recipes, the videos stay where they are and you may
want to move them yourself.
Deleting a category does not delete its bookmarks — they become Uncategorised.
#4-4 How many categories you get
Five on the free plan, counting the five you started with. Delete or rename one to make room for a
category of your own; the ceiling stays at five however you get there. Pro has no limit.
The limit only ever stops you creating a sixth category. It never stops a save and never stops the AI.
#4-5 Uncategorised
Bookmarks live in Uncategorised when they were saved without AI, when the AI could not match them to
any of your categories, or when the category they were in has been deleted. It behaves like any other
filter, so you can work through it when you feel like tidying.
AI descriptions and tags
#6-1 What the AI writes — and what it does not
When AI is on, saving a page writes a short description, adds tags, and sorts the page into one of
your existing categories.
It does not write the title. Titles come from the page itself, which is why they appear even when you
are signed out, offline, or out of credits. Anything the AI writes, you can edit.
#6-2 What a credit is, and what spends one
A credit is one piece of AI work on one bookmark — the description, the tags, and the category
together.
Three things spend a credit: saving a page with AI on, regenerating a description, and opening an
imported bookmark for the first time. Nothing else does. Editing text yourself, searching, sorting,
adding your own tags, and exporting are all free.
If the AI fails — the page would not load, the connection dropped — the credit is not taken. You are
only charged for work you actually got.
#6-3 Your credit counter
The AI card in settings shows what is left, in the block under the toggle:
38 of 50 AI credits left · renews 12 September.
In your first period it names the expiry instead, because the 300 do not renew — they are replaced
by 50: 238 of 300 AI credits left · they expire 12 September, then 50 a month.
The free plan gives you 50 credits a period, and a period is 30 days counted from the day you
created your account — not the first of the calendar month. The counter names your own renewal date.
Pro is unlimited, and the counter says so instead of counting.
Your first period is different: it starts with 300 credits, once. They expire at the end of that
period and are replaced by the standing 50, so the counter says when they go rather than when they
renew.
With your own AI key in use, the counter says so instead of counting: your saves are not drawing on
anything of ours.
Beside the regenerate button you get the short form of the same number, so the cost is visible where
you are about to spend it.
#6-4 When your credits run out
Saving carries on exactly as before. The page is saved, with its title, address, picture, and date —
only the description, tags, and category are missing.
Those saves are not caught up automatically when your credits renew. A page stays as it was saved
until you ask for it: open the bookmark and regenerate, and it spends a credit then.
#6-5 Regenerating a description
If a description is wrong or thin, regenerate it from the bookmark. Regenerating uses one credit and
replaces what was there, so copy anything you want to keep first.
Regenerating reads the page again, which means the page has to be reachable. A page that has since
gone offline cannot be regenerated.
#6-6 The language of AI text
Descriptions and tags can be written in a language you choose, in the AI card in settings — useful if
you read in English but organise in your own language. The setting does not reach the title, which
comes from the page.
#6-7 Custom AI instructions Pro
Tell the AI how you want descriptions and tags written, and it follows your instruction on every save:
keep it to one sentence, always note the publication date, tag by client name, never use marketing
language.
It is one instruction that applies to everything you save, not a rule per category — but it can
carry a conditional rule, applied only where it fits: "When saving a car advert, start the
description with the make, model, year, mileage, and location." Change the instruction and it takes
effect on the next save; it does not rewrite what is already described.
Instructions govern descriptions, tags, and the category. They do not change the title.
#6-8 Using your own AI key Pro
You can use your own AI account instead of ours. The description and tags are then written by your
provider: the request goes straight from your browser, never through our servers. You also pick the
model, which is the more common reason to do it. It costs the same as Pro, and your saves stop
counting against anything of ours.
First, get a key from your provider. LinkMartin works with OpenAI,
Anthropic, or any OpenAI-compatible service. The card links straight
out — Get a key for OpenAI/Anthropic — and you make the key in the provider's own
console, on the page called API keys in both. Copy it when it is shown; most
providers show a key once and never again. The key is free to make; using it is not — set up billing
while you are in the console, because a key with no money behind it does not work.
Then fill in the fields. Pick the provider and paste the key. The model is filled
in for you — gpt-4o-mini for OpenAI, claude-haiku-4-5 for Anthropic — and
you can type a different one over it; your provider's documentation lists the names it accepts. An
OpenAI-compatible service asks for two more things: its base URL, and the model id, which has no
default because only your service knows what it offers.
Click Save key. The key field then shows only the beginning and end of what you
saved — sk-a…hQAA — and a Remove key button appears. That is how you
know it is stored.
Your key stays in that browser. It is never synced and never sent to us, so if you
use LinkMartin in a second browser, enter it there too. Remove key deletes it from
the browser you are in; signing out, or letting Pro lapse, removes it too, and you enter it again
when you return.
What your own key does not change. Your library still syncs the way it always did,
so while you are signed in the bookmark record — including the snippet of page text — is stored with
your account exactly as before. And while AI is on, that snippet is still sent to OpenAI's embedding
model to power related bookmarks, whichever provider you chose to do the writing. Your own key
changes who writes your descriptions, not what sync keeps.
If the key stops working, pages are still saved — just without a description, tags,
or a category. We never fall back to our own AI while your key is set. LinkMartin does not yet tell
you that a key has failed, so if saves stop being described, check three things: that the key is
still valid, that the model name is one your provider accepts, and that your provider account has
credit.
#6-9 What leaves your device
With AI on, the content of the page you are saving goes to our AI provider so a description and tags
can be written for it. With your own AI key, it goes to your provider instead of ours. With AI off,
nothing is sent to any AI provider.
Signed in, your bookmark records — including a snippet of each page's text — are also kept on our
servers. That is sync: it is how your other browsers get your library.
Signed out, no page content leaves your device. Searching, and the matching for the card in Google,
happen on this device in every mode.
Bringing bookmarks in
#8-1 Importing from Chrome
Import and export → From Chrome → Import. Chrome asks to read your bookmarks and access is released as
soon as the import finishes. Each folder in your browser becomes a tag, so your structure survives.
#8-2 Restoring a LinkMartin backup
Import and export → From a file → restores a .zip archive that LinkMartin itself
exported. It is the way to move your library to a new device, or back it up and bring it back.
#8-3 What survives an import
The address, the title, any description or note, existing tags, and the folder structure as tags. Your
original save dates come across as they are — a page you bookmarked in 2019 still says 2019, not today,
so sorting by date still tells you something.
#8-4 Imported bookmarks arrive plain
Imported bookmarks arrive with their title and address but no description, tags, or category. Open one
and it gets all three — and that uses one credit.
This is deliberate. Writing a description means reading the page, and LinkMartin can only read a page
that is open, so importing 900 bookmarks cannot describe 900 pages. It also means an import cannot
quietly spend your credits behind your back: nothing is spent until you click.
#8-5 The 300 credits you start with
Create an account and it starts with 300 AI credits instead of the usual 50 — a one-off, so
you can have your existing bookmarks described and tagged without waiting a month for the
allowance.
They last 30 days. Anything unused on day 30 does not carry over: your balance becomes
50 credits, and it is 50 every 30 days from then on — the standing rate on the free plan.
Your own date is in Settings.
Pro has no credit limit, so none of this applies there.
#8-6 Importing from Chrome again without making duplicates
Safe to repeat: importing from Chrome again only adds new addresses, and anything already in your
library is skipped. A page you deleted stays deleted. Import from Chrome once a month if you like.
Account and sync
#10-1 What an account gives you
Two things: AI descriptions and tags, which run through your account so you never need an API key, and
sync. Everything else works signed out.
#10-2 What sync covers
Your bookmarks sync to everywhere you have installed LinkMartin and signed into the same account —
including a second browser on the same machine. A device without LinkMartin installed gets nothing.
#10-3 Which browsers LinkMartin runs in
Chrome, Edge, Brave, Vivaldi and Opera. They are all built on Chromium — the same engine, the same
extensions — so LinkMartin is one extension that runs in all of them, and the
browsers page lists them.
What differs is where each browser gets its extensions from. Chrome, Brave and Vivaldi install from
the Chrome Web Store, though Vivaldi keeps Web Store support behind a setting. Edge has its own
Add-ons store and can also install from the Chrome Web Store once you allow extensions from other
stores. Opera needs its Install Chrome Extensions add-on before the Chrome Web Store will
work.
Signing in syncs your library between the browsers you use LinkMartin in, on the same computer or
another one.
LinkMartin is a desktop extension. Chrome on Android and iOS cannot run extensions at all, so there
is no phone version.
One thing to know wherever you install it: the card appears in Google results.
Some browsers search Bing or their own engine by default — if yours does, you will not see the card
until you switch your default search to Google.
#10-4 Sync said it failed
A failed sync is shown on the Account & Sync card with a try again link, and your bookmarks
are safe on this device meanwhile — sync is a copy, not the original. If it keeps failing, check your
connection first, then get in touch.
#10-5 Forgotten password
Use Forgot your password? beneath the sign-in button, and we will email you a link to set a
new one. While you are signed out your library stays exactly where it is — signing out or losing a
password never removes bookmarks from this device.
Storage and privacy
#11-1 Where your bookmarks are kept
On this device. Bookmarks and page pictures are stored in this browser, and the library works with no
connection at all. Signed in, a copy is also synced to your account so your other installations can see
it.
#11-2 Screenshots are thumbnails, not copies
The picture on a bookmark is a thumbnail of the page as it looked when you saved it. It is not a saved
copy of the page: if the link dies, the page is gone, and the picture is all that is left.
If keeping the content matters, save the page itself as well — LinkMartin remembers where things were,
not what they said.
Signed in, the thumbnail is also stored with your account so your other browsers get it. It is
private: only you, signed in, can open it — there is no public address to leak.
#11-3 The permissions LinkMartin asks for
Access to the pages you save — that is how it reads the title and the text and takes the picture. Your
browser words this as access to all websites, because you can save any page; LinkMartin reads a page
only when you click save, never in the background.
Your browser will also list "read your browsing history". That is Chrome's name for the permission
that lets LinkMartin see the title and address of the tab you are saving — and of the tabs you select
for a batch save. It does not read your history, and nothing you browse is recorded unless you save
it.
Your browser bookmarks — only if you choose to import them, and asked for at that moment. And the card
in Google runs on google.com and needs nothing extra; you can switch it off in settings.
#11-4 How much space you are using
The Storage card shows what your library is taking up on this device. Page pictures are most of it.
Settings, card by card
A map of the panel, so a search for a setting name lands somewhere.
#13-1 Account & Sync
Sign in or create an account, see when you last synced, and sign out. Signing in turns on AI and
sync.
#13-2 Google results
Show your bookmarks in Google, and bring the card back if you have hidden it. This is the card's on-off
switch.
#13-3 AI descriptions and tags
Turn AI on or off, see your credits, choose the language of AI text, and — on Pro — set custom
instructions and use your own AI key.
#13-4 Categories and tags
Create, rename, and delete categories, see how many of your five you have used, and manage your
tags.
#13-5 Appearance
The colour theme for the panel, library, and settings.
#13-6 Import and export
Bring bookmarks in from Chrome or a file, and download a copy of everything.
#13-7 Storage
How much space your library uses, and where to delete everything on this device.
