I replaced four different apps with ThinkGenieAI. My meeting notes, PDFs, and journal all finally talk to each other.

The AI summaries after every lecture are shockingly accurate. Studying for finals has never felt this organized.

★★★★★

I run client calls all day. The transcription and action-item extraction alone pay for the subscription every week.

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.
