Features

Memory that compounds

Capture anything

Photos, screenshots, links, voice notes, forwarded messages, quick thoughts — just text it. No app to open, no workflow to learn.

Retrieve instantly

Ask questions in plain English over everything you've ever saved. Semantic search that understands what you mean.

Reflect over time

Weekly summaries, recurring themes, evolving thinking. See patterns across months of your own knowledge.

Transform into knowledge

Turn raw captures into structured notes, reading lists, research folders, and decision logs — automatically.

Use cases

Built for the way you actually think

Researchers

“that paper about attention mechanisms I screenshotted at the conference”

Snap a whiteboard, forward a PDF, text a half-formed idea between sessions. Search by concept when you're finally writing.

Designers

“dark mode dashboards I've been saving”

Screenshot inspiration from any app, forward Dribbble links, snap real-world signage. A visual library that's always in your pocket.

Developers

“that error boundary pattern from the blog post”

Forward articles, screenshot terminal output, text code snippets to yourself. Find that one thing you saw three weeks ago.

Students

“lecture notes from week 6 constitutional law”

Photograph whiteboards, forward reading links, voice-note your thoughts after class. Everything searchable before the exam.

Writers

“the interview where she talked about craft”

Forward articles, text quotes that catch your ear, voice-note observations on a walk. Pull up sources while you're drafting.

Product managers

“competitor onboarding screenshots from last month”

Screenshot competitor apps, forward user feedback emails, text meeting takeaways. Build context without a dozen folders.

How it works

Three steps

1

Text

Send Librarian anything — a photo, a link, a thought, a voice note. Just text it like you would a friend.

2

It organizes

Librarian reads, tags, and connects what you send. People, projects, topics, and themes emerge automatically.

3

Ask anytime

Search your memory in plain English. Get answers, summaries, and things you'd forgotten you saved.

Your memory, always with you.

Stop losing the things you notice. Start building a memory that actually works.
