FeynmanLM vs RemNote
RemNote is an all-in-one student platform: notes that auto-generate flashcards, PDF annotation, exam schedulers, and a growing AI layer. It's arguably the most feature-complete study app for coursework. FeynmanLM is narrower and more opinionated: track every source you consume, schedule it, and verify understanding through Feynman-style AI dialogue — with your data in your own iCloud and the AI you already pay for.
At a glance
| FeynmanLM | RemNote | |
|---|---|---|
| Price | Free to download — no tiers, no lifetime license to weigh up | Free tier (capped); Pro $96/yr; Pro + AI $216/yr; $395 lifetime (AI still +$10/mo) |
| AI costs | Pay-as-you-go from a prepaid balance ($5 free to start): any model in Chat at provider API price +15%, or 1¢ per tool call via an AI subscription you already pay for | Metered AI credits included in tiers (1,000/mo on Pro, 20,000/mo on Pro + AI); no bring-your-own-key |
| Platforms | Native macOS app (macOS 14+) | Web, Mac, Windows, Linux, iOS, Android |
| Data storage | Local SQLite + files in your private iCloud container | RemNote's cloud by default; local-only knowledge bases on desktop lose sync |
| Source ingestion | Automatic: articles, papers, podcasts, books, YouTube, X posts | PDFs, slides, lecture recordings, web clipper — no podcasts or YouTube |
| Review method | Feynman-technique dialogue with an AI tutor | Spaced-repetition flashcards (SM-2/FSRS), AI-generated cards, AI quizzes and grading |
| Model choice | Any MCP-compatible AI (Claude, ChatGPT, Gemini, Grok), or any API provider in-app | OpenAI/Anthropic/Google behind RemNote's credit system |
| Export | Files in your iCloud Drive; SQLite you can open | Markdown/JSON export; rich structure and scheduling history don't survive cleanly |

Pricing: subscription + credits vs free app + pay-as-you-go
Meaningful AI use on RemNote costs $216/yr (Pro + AI), and even the $395 lifetime license excludes AI credits — AI stays a $10/mo add-on forever. The credits are RemNote-denominated: you can't bring your own key or your existing ChatGPT/Claude subscription.
FeynmanLM has nothing to buy. The app is free to download, and AI comes out of a prepaid balance you top up through Stripe, starting with $5 free. Two rates, mixable: any model in the in-app Chat at that provider's own API list price plus a 15% margin, metered on the exact cost the provider reports; or 1¢ per tool call if you drive FeynmanLM over MCP from the Claude, ChatGPT, Gemini, or Grok subscription you're already paying for — the inference is on that subscription, the cent covers reading and writing your library. Per-conversation costs are shown to the cent, and a daily spend cap bounds runaway usage.
Three years of RemNote Pro + AI is ~$648 committed up front. FeynmanLM's equivalent number is $0 for the software plus whatever AI you chose to run — which is the honest answer, not a dodge: it's the one line item you control directly.
Where RemNote is better
- Course-based studying. Annotating lecture slides and PDFs, auto-deriving flashcards from your note outline, exam schedulers that compress reviews before a test date — for a semester with exams, RemNote is purpose-built.
- Every platform. Web, Windows, Linux, Android, iOS. FeynmanLM is Mac-only.
- Integrated notes. RemNote is a real outliner/note-taking app; FeynmanLM deliberately isn't.
- Usable free tier. Unlimited notes, flashcards, and devices for $0 (with caps on PDFs and AI).
- Built-in flashcard scheduling. If you want classic spaced repetition with image occlusion and clozes, it's all there.
Where FeynmanLM is better
- Explaining beats grading cards. RemNote's review is still fundamentally flashcards — even its AI grading scores your answer to a fixed card. FeynmanLM's review is a conversation: you explain the source from scratch and the AI probes gaps it discovers along the way. See Why Quizzing?
- Your whole consumption stream, not just coursework. Podcasts with full transcripts, Safari reading list articles, books, papers, YouTube, X posts — auto-discovered, not manually uploaded. RemNote has no podcast or YouTube ingestion at all.
- Real money, not a private currency. RemNote credits are RemNote-denominated, refilled monthly, and spendable nowhere else. FeynmanLM bills what the provider actually charged plus a 15% margin — or a flat 1¢ per tool call if you'd rather lean on a subscription you already have. Any provider, switch anytime, and the ledger is in dollars you can check.
- Data in your iCloud. RemNote's synced knowledge bases live on their servers (local-only mode exists but gives up sync). FeynmanLM syncs through your own Apple account; the app's servers never store your library.
- Simpler by design. RemNote is famously dense — rems, portals, descriptors, templates. FeynmanLM has one loop: track, schedule, read or listen, explain it back.
Which should you choose?
Choose RemNote if you're a student working through structured courses with exams, want notes + flashcards + PDF annotation in one place, or need Windows/Android.
Choose FeynmanLM if you're on a Mac and your learning is source-driven — articles, papers, podcasts, books — and you'd rather own your data outright and pay for AI by the token you actually spent, instead of renting credits by the year.
