What it does

One place for everything you know

Notes, PDFs, voice, and knowledge — connected by AI that actually understands your work.

Write & sketch freely

Rich text, handwriting, and drawing in one canvas — with palm rejection and unlimited pages for your stylus.

Annotate any PDF

Highlight, comment, sign, and search across your entire PDF library — with OCR built in.

Record & transcribe

Capture meetings and lectures, then get speaker-labeled transcripts, summaries, and action items automatically.

Chat with your notes

Ask questions across every document, PDF, and transcript you've ever saved — and get answers with sources.

Turn notes into anything

Generate study guides, flashcards, blog posts, presentations, or emails from any note in one click.

See how it all connects

Backlinks and a knowledge graph reveal the relationships hiding across your notes and documents.

OCR handwriting & scans

Snap a photo of a whiteboard, receipt, or handwritten page and get clean, editable text in seconds.

Image → Notes

Drop in any image and Gemini vision writes a structured markdown note — perfect for slides, diagrams, and screenshots.

Export anywhere

One-click export to PDF, Word, or Google Docs — with clean formatting and your original headings intact.

Turn any note into a Google or Outlook calendar event — or download a .ics file. AI extracts dates, times, and locations automatically.

Instantly visualize any note as a radial mind map. See how ideas branch and connect at a glance.

Video notes

Record or upload a video and get a full transcript plus AI-organized study notes with key points and timestamps.

Questions

Frequently asked questions

Can I import notes from other apps?+

Yes. ThinkGenieAI imports directly from Evernote, Notion, OneNote, and plain Markdown or PDF exports — your formatting and attachments come along with it.

Is my data private and secure?+

Your notes are encrypted in transit and at rest. AI features only process what you explicitly ask about, and you can turn off AI training on your content at any time in settings.

Does it work offline?+

Writing, drawing, and reading work fully offline, with automatic sync once you're back online. AI features require a connection.

Can I use it with a stylus and tablet?+

Yes — full palm rejection and pressure-sensitive drawing are supported on iPad, Android tablets, and Windows touchscreens.

What happens if I cancel?+

You keep read access to everything you've created and can export all your notes and PDFs at any time — no lock-in.
