You read.Pluto remembers.

Pluto Library files every video, podcast and article you save. It pulls out the facts, companies and ideas inside, links them across your whole library, and answers with citations, so you can write what you actually think.

How it works

Pluto Library reads
like a researcher.

01 / 03

File.

Every video, podcast and article gets read, summarised, given a call number and put on the right shelf.

02 / 03

Connect.

Facts, companies and concepts are pulled out of each item and tied to everything else you've saved.

03 / 03

Think.

Ask a question and Pluto reads the items that matter, weighs who agrees and who doesn't, and cites every claim.

Pluto Library works from a folder you already keep. There is nothing to tag and nothing to sort.

Choose Answer, Connect, Debate or Project. Every claim comes back with a call number you can open.

One library for everything
you read, watch and hear.

01Brain

Your whole library at a glance: areas, topics and what came in this week.

02Ask

Answer, Connect, Debate or Project, from a quick pass to a deep read of full transcripts.

03Write

Substack deep dives, articles and posts on X in a voice you choose, with every claim cited.

04News

Daily and weekly briefings from what you saved, linked to their sources and kept in a calendar.

05Library

Every item with its call number. You choose which sources, topics and years answers can use.

06Facts

Numbers your sources gave, with who said them and where, ready to sort and filter.

07Companies

Who comes up and how they're tied: who works with, competes with or invests in whom.

08Concepts

A concept map across your library, the models speakers explain, and a primer for each topic.

09Lenses

The leading voices, how they think, where they disagree, and a lens of your own.

Every claim cited

Call numbers like L108 open the exact passage, so you can check before you publish.

It organises itself

Every item gets a summary, its topics and a call number, then lands on the right shelf. No folders to sort and no tags to add.

Facts kept apart from views

Raw material lives on Facts and Companies. Opinions and frameworks live on Lenses.

Outside knowledge, labelled

Switch on Claude's own knowledge when you want it. Anything not from your library is marked.

Read for the joy of it. Keep every favourite article, podcast and talk in one place. Pluto Library shows you how it all connects, so your thinking gets clearer the more you read.

A few things you might be wondering.

What can Pluto Library read?

Videos and podcasts as transcripts, articles, PDFs, Word files and posts. Video to Text saves transcripts of what you watch into a folder, and Pluto Library Sync brings new files in. You can also add files and paste text by hand.

Where is my library kept?

In your own Claude account. Open Pluto Library at claude.ai on your phone or computer, signed in, and it's all there.

What does it cost to run?

It runs on your Claude account. Every action shows an estimate before it runs: filing an item with Haiku is a fraction of a cent, and a standard answer is about $0.08 to $0.21. On a Claude plan, questions use your plan's limits instead of being billed.

Which models does it use?

Haiku 5.5 for filing and quick passes, Sonnet 5.5 for answers and debates, and Opus 5.5 for connecting ideas and projects. You can pick a different model for any step.

Will answers mix in things I never saved?

Only if you switch on Claude's knowledge. Anything that comes from outside your library is marked as such, and may be out of date.

Can it write like me?

Add a style from 3 to 5 samples of your writing, or of a writer you admire. When you edit a draft yourself, the style can learn from what you changed.

Can I control what answers use?

Yes. Choose sources, topics, years and countries, switch single items or parts of items off, and archive anything you don't want answers to read.

Never lose a good idea again.

Pluto Library turns what you read into something you can ask, check and write from.
