How to read a paper in three passes, not one
An AI that files, never a feed · invite-only
Save anything. The AI files it. Find it in a word.
Course readings, trip research, the jacket you nearly bought. An AI assistant reads each thing you save, files it under the right category and writes the one line you’ll search by months later — and shows you what it decided, so a wrong guess takes one tap to fix.

Nine kinds, each with its own card: linksarticlesimagesvideoproductsquotesnotescoloursPDFs
How it works
One input. No filing.
The same field saves, searches, writes a note and runs commands. Everything else — the kind, the tags, the colour, the reading time — is filled in for you while the card is already on your wall.
- 01 URL bottosson.github.io/… Save
Paste it and move on
The card appears instantly. Nothing waits on a spinner, and nothing asks you where to put it.
- 02 Lecture 4 — split attention
The assistant files it
It reads the page, picks the category and writes a short description — the sentence search will match later.
- 03 the blue houses in Bruges
Search the way you remember
Words from inside the page, the description it wrote, the colour you recall. Half a memory is enough.
Your assistant
It reads what you save, so you don't have to name it.
A photo with no filename, an article you skimmed, a product page in another language. Each one is read once, given a category, and described in a sentence a human would actually say — and that sentence is what search matches.

Description it wrote
Your handwritten notes on cognitive load — the worked-example effect and the split-attention diagram from lecture 4.
Editable. Whatever you change is what search uses.

Different things, different questions
- Travel
- place, dates, price you saw
- Shop
- product, size, seller, price history
- Study
- topic, source, where it fits in the course
When it isn't sure, it asks
Low-confidence items wait in Needs review instead of being filed wrongly. One tap decides, and your correction is remembered.
Tags
Tags you never have to keep tidy.
The assistant proposes a few from the tags you already use, in your own words. Keep them, drop them, add your own — or ignore the whole idea. Search works either way, because it also reads the page text and the description.

Two tags on the card, the rest behind a count. A card is for recognising the thing, not for auditing it.

41 of 1 248 items
Combine a category with tags, a domain or a date to narrow a thousand items to forty — then save that as a search you can come back to.
Never a chore
No required fields, no folders to file into, no empty-tag guilt. An untagged item is still found by its text, its colours and the sentence the assistant wrote.
Snapshots
The rules changed. Your copy didn’t.
Every save keeps a full-page snapshot and the readable text. When a deadline moves, a clause disappears or the page is taken down, you still have the version you read — and we point at exactly what changed. That is the difference between a bookmark and evidence.

Read it without the noise
Reading mode strips the page to its words at a comfortable measure — offline, in your own type, still there when the original is behind a paywall.

Saved it twice? We’ll show you the difference.
Mnemo recognises a page you already hold and offers the diff instead of a second copy — so you notice the edit nobody announced.
Quotes
Keep the sentence, not just the link.
Highlight a line while you read and it becomes its own card — searchable on its own, and still able to take you back to the exact paragraph it came from.
While you're reading

At the end of the first pass you should be able to answer five questions: the category, the context, whether the assumptions hold, the contribution, and whether the paper is clear.
The source, the author and the paragraph are attached for you. Nothing to fill in.

- ⌘⇧K Highlight, one keystroke, done.
- Search quotes only Half-remembered wording is enough to find one.

Privacy
Nobody else is invited in.
Mnemo has no feed, no followers and no public profile — not as a setting you switch off, but because none of it was built. Even the operator console can manage your account without ever seeing what's in it.
-
Yours alone
One library per person. No sharing surface exists to leak through.
-
Not training data
The assistant reads your item to file it, then forgets it. No ads, no profiling.
-
Admins can't read it
The console shows counts and roles. No titles, no URLs, no snapshots.
-
Leave with everything
One click exports every item, snapshot and note in open formats.
Secure cards
For the few things nobody should be able to read.
A lease, a doctor's letter, notes from a hard conversation. Encrypted on your device with a passphrase only you hold — we store the result and cannot open it, for support or for anyone else. Even the title is unreadable to us.
Not a password manager. No autofill, no breach alerts, no 2FA codes — and if you lose the passphrase, nothing can recover it. Keep credentials where they belong.

This is all a secure card shows until you open the safe — and all we ever see.
- Works offline Save on a plane; it syncs when you land.
- Installs as an app Desktop, iOS, Android — one codebase, no store.
- / Every action has a key. The mouse is optional.
- Nothing goes by accident Deleted things wait seven days in the bin, then leave for good.
- Archive, don't discard Finished with something? Shelve it — no deadline, still searchable.
Built for speed
Fast enough to be a habit.
Saving takes under a second and never blocks the page you're on. Moving through a thousand items is a keystroke, not a scroll. If a tool interrupts you, you stop using it — so this one doesn't.

Questions
Before you ask
- Is this another bookmark manager?
- No folders, no hierarchy, no maintenance. You save; it files. The unit isn't a URL — it's whatever you were looking at, kept as it looked.
- What happens when a page dies?
- You keep the snapshot and the readable text. A dead link stays a usable memory instead of a 404.
- Does the assistant guess wrong?
- Sometimes. When it isn’t confident it says so and asks instead of filing badly — and your correction sticks, so the same mistake doesn’t come back.
- Can I get my data out?
- Any time, in one export: items, notes, snapshots and text in open formats. Leaving is a feature, not a support ticket.
- Can I keep something genuinely private?
- Yes — a secure card is encrypted on your device with a passphrase we never see, title included. It's the right place for a lease or a medical letter, and the wrong place for passwords: no autofill, no breach alerts, and no recovery if you forget the phrase.
- What if I delete something by mistake?
- Undo is one keystroke, and beyond that it sits in the bin for seven days — with its tags, quotes and snapshots — and comes back in the same place on your timeline.
- Why invite-only?
- Every account is a private library with real storage behind it. We add people at the pace we can keep it quiet, fast and intact.
