Your research inbox

More than a folder of PDFs.

ForeverLM catches what you want to read, keeps the original source, and turns the surrounding research trail into something you can actually use.

01

Paper manager

Import from arXiv, PubMed, a DOI, or a PDF. ForeverLM fetches the full paper and metadata, catches duplicates, and keeps every paper searchable.

02

Reading list

Save something in Safari, Chrome, or Brave and it appears automatically. Keep papers and articles together, then organize them into Projects when they matter.

03

X posts & YouTube

Sync bookmarked X posts, liked YouTube videos, or a dedicated ForeverLM playlist. Transcripts and threads become searchable sources, not forgotten tabs.

04

Academic presentations, with the papers attached

Watch a talk with its transcript and slides. ForeverLM can scan the presentation for cited papers, resolve them, and import the ones you want straight into your library.

MCP built in

Your knowledge base, inside your chat app.

You already think alongside an AI assistant. ForeverLM connects your whole library to it over MCP, so Claude or ChatGPT can search your sources, pull the full text, quiz you Feynman-style, and save the review back into your library.

No copy-pasting PDFs into chat windows. No re-explaining what you're studying. Your assistant simply knows what you know.

Why ForeverLM is different

Built by researchers, for researchers.

ForeverLM comes out of a working research habit, not a productivity trend. It optimizes for one thing: understanding that lasts.

01

Not another note-taking app

There are plenty of second brains to garden. ForeverLM tracks the sources themselves. You bring the content; the AI brings the quizzing.

02

No flashcard graveyards

Instead of stale decks, your AI generates fresh Feynman-style questions from the source every time. Retrieval practice, without the maintenance.

03

Real papers, first class

Import from arXiv, PubMed, or any DOI. PDFs are fetched, metadata extracted, and duplicates caught, the way a reference manager should behave.

04

Quizzing over highlighting

The research is unambiguous: testing yourself beats re-reading. Every review session probes what you actually understood, then saves the transcript.

05

Your files, no lock-in

Everything is plain files and SQLite in your own iCloud Drive. No proprietary cloud, no export hostage situation, nothing on our servers.

06

Works with the AI you already use

Bring your Claude or ChatGPT subscription over MCP, or use built-in pay-as-you-go AI. Either way, no new monthly fee.

Storage

It just lives in your iCloud.

Your library is stored in your own iCloud Drive and synced by Apple, so it's on every Mac you own, backed up without thinking about it, and readable even if ForeverLM disappeared tomorrow. We never see your data.

  • Synced across your Apple devices by CloudKit
  • Works offline because it's just files on disk
  • Private by design: no accounts, no server-side library
Pricing

No subscription. Ever.

The app is free to download. Nothing to unlock, nothing to convert. You pay only for the AI you actually use, in two ways that you can mix.

Built-in AI

Chat in the app

$25minimum AI balance

Auto top-up can restore your balance to $25 when it reaches $5

  • Every source type, unlimited library
  • Choose your model; a cheap one stays cheap
  • Every provider and OpenRouter cost is included
  • Top up when you run out. That's it.
MCP

Bring your own AI

1¢ per tool call

Use the Claude or ChatGPT plan you already pay for

  • Your whole library, inside your chat app
  • Your subscription covers the thinking. We bill only for reading and writing your library
  • A daily cap keeps a chatty assistant from running up a bill

Background work such as tidying transcripts, pulling paper metadata, and building search indexes uses the same dollar balance. Costs stay micro-cent precise.

Start remembering what you read.

Download the app for your private library, then connect it to the AI assistant where you learn.
