Why Inkstone

The hard part of studying was never the learning

It's turning a thick book into cards you can actually review โ€” and then reviewing them on schedule. Inkstone does both.

โœ• Making cards by hand takes hours

Highlighting, formatting, and typing up one textbook can eat whole nights.

โœ“ AI builds a deck in minutes
โœ• Anki is powerful but complex

Templates, add-ons, syncโ€ฆ many people quit before they ever start studying.

โœ“ Open it and just study โ€” zero setup
โœ• Reviewing by guesswork

You never quite know what to review today, so memory comes down to luck.

โœ“ FSRS schedules every day for you
Core features

Turn a whole book into your memory system

From generation to review, end to end.

๐Ÿค–

One-tap AI flashcards

Upload a PDF, text, or even a scan. The AI parses it, extracts what matters, and writes clean Q&A cards โ€” adding mnemonics and key distinctions along the way. Math formulas are preserved.

๐Ÿง 

FSRS science-based review

Inkstone uses the industry-leading FSRS memory algorithm to predict your forgetting from every rating and resurface each card on the optimal day โ€” far better than cramming.

๐Ÿ“”

Warm notebook design

Ring holes, torn edges, ruled paper, washi-tape rating buttons โ€” it feels like studying in a real notebook. Warm, focused, and inviting to open.

FAQ

You might be wondering

How is Inkstone different from Anki?

Anki is powerful but has a steep learning curve, and you build every card by hand. Inkstone is all about one-tap AI card creation and being ready out of the box: upload your material and a deck is generated for you, in a warm notebook-style interface with zero setup. You can also import your existing Anki decks and keep using them.

What formats can I import?

PDFs (including scanned files, with automatic OCR), pasted plain text, and Anki formats such as .apkg / .colpkg / .csv / .tsv. Math formulas are preserved and rendered correctly.

Is it free?

Yes โ€” you can use Inkstone for free and study a set number of new cards each day. More AI generation credits, Anki import, and AI explanations are Pro features. See the app for current limits and pricing.

Is my data safe?

Material you upload is used only to generate your flashcards. We take privacy seriously โ€” see the Privacy Policy linked in the footer.

Which devices are supported?
