Write it down. Linko keeps it in order.
$0
Everything you learn, connected.
Save what you read, watch and hear, and note it in your own words, even out loud. Linko files it all, connects it, and brings it back when it matters.
All in one place.
Whatever you keep lands on your Home, newest first, and Linko starts filing it.
It files itself.
Linko reads each note and resource as you save it, files it under a topic, and shows you where it went. Make a tag when you want a group of your own.
However it comes, catch it.
Type a thought, say it out loud, paste a link, look up a book, or save from your browser and your phone. Nothing to name or file first.
Write it
A line in your own words. Press Save, and Linko takes it from there.
Say it
Talk for up to five minutes. Linko writes it up as a note and keeps the transcript.
Paste a link
Videos, articles, posts and podcasts. Each one gets a page of its own.
Look up a book
Type the title and pick it by its cover.
Save from your browser
Select a line on any page and add it to Linko as a note, linked to the page.
Share from your phone
Share from YouTube, a podcast app or your browser, and add a line if you like.
Every source gets a page.
Save an article, a video or a book, and it gets a page of its own: what it says, the key points, and every note you took on it.
Article: Read, and keep the line.
Select a passage and choose Note this. A note opens beside it with the quote, linked to the article.
Video: Watch, and note the moment.
Key points split a long video into chapters. Click a time to play from there, and Note this moment puts the time in your note.
Book: Finish the book, keep what it taught you.
Mark where you are as you read. Every passage you keep stays on the book’s page.
And more: Posts, podcasts, tools, any link.
Whatever you save gets a page that says what it’s about, with every note you take on it.
Saving is the easy part. Coming back is the hard part.
Linko is built for coming back.
Your past thinking, back when it matters.
Start writing, and the notes you wrote on the same thing before come back beside the draft. Linko says how the new one connects, so you build on what you know instead of starting over.
Ask what you know.
Your notes answer back. Ask a question and the answer comes from them, every source cited. And a few questions a day keep what you read with you.
Ask Linko
Answers from your own notes and resources, each point linked to where it came from. Keep a good answer as a note.
Today’s review
A few questions from your notes each day, so what you read stays with you. Try it.
See what your notes add up to.
Every topic and tag opens with your current understanding: a few lines on where your thinking stands, each pointing back to the notes it comes from. The more you keep, the more it can say.
A week in
Five notes in, Linko says what they add up to, in a line that points back to the note it came from.
A month in
New notes sharpen it. Every line links to the notes behind it, so you can check it.
Three months in
The topic fills out: subtopics of its own, and a map of what sits around it.
Watch your knowledge grow.
Everything you save adds to your rings: a slice for each topic, a ring for each year. The further a slice reaches, the more you have learned there.
Share your rings as an image. It shows your topics and counts, never your notes.
Yours, and private.
What you write in Linko is your own thinking. It stays that way.
Private by default.
Your account and every note start private. You choose what friends can see.
Encrypted before it’s stored.
Private notes, voice transcripts and your conversations with Linko are encrypted at rest.

The AI services behind Linko work for us under contract and don’t train on your content.
No ads. No trackers.
We don’t sell your notes or show you ads, and nothing here tracks you for advertising.

Questions before you start.
What is Linko?
Linko is a notes app and AI knowledge base at linko.study. It connects everything you learn and brings it back when it matters. Write notes and save articles, videos, podcasts and books on the web, iOS and Android, or with the web extension. Linko adds tags and topics automatically and links your notes across sources. Daily review brings old notes back, and Ask Linko answers from your notes, showing the notes it used. Linko MCP lets Claude and ChatGPT use your notes, with citations.
Do I need to organize everything before saving it?
No. Save what matters first. Linko files notes and resources under topics as you add them, and you can change types, topics and tags at any time.
How is Linko different from Notion, Obsidian, or AI memory?
Notion and Obsidian give you flexible tools to build and maintain a system. AI memories keep context inside one assistant. Linko organizes your notes and what you save into knowledge you can revisit directly and bring into other AI tools.
What can I add or import?
Add notes, links, books, articles, videos, podcasts and voice notes. Importing from other apps is coming soon.
Is my data private?
Notes are private by default. Private notes are encrypted before storage, and you choose what to share. The AI services Linko uses don’t train on your content.
Is there a free plan?
Yes, with no time limit. Your first 50 notes and resources get everything Linko does, including topic understanding and an Ask Linko trial. After 50, everything you saved stays yours to read, edit, search and export; upgrade to Pro to keep adding.
What counts toward the 50?
Every note and every article, video, podcast or book you save counts as one. Deleting one doesn't give the slot back.
Does Pro have limits?
Yes, set well above everyday use. The numbers are on the plan limits page.
I've used Linko before. What changes for me?
Your notes and resources stay unlimited. Your next 50 get everything Linko does, like a new account; after that, AI reads 20 items a month for you. Subscribe to Pro before Dec 1 to keep the founding price for as long as you stay subscribed.
Can I export my data?
Yes. Your knowledge stays yours, and you can export your notes and resources as standard Markdown.
Can I use Linko with other AI tools?
Yes. Add Linko to ChatGPT as a plugin, or connect Codex, Claude and other tools over MCP. They can search your notes and resources and save new notes, and Linko remains the knowledge source you control.
