Whatdoyouactuallyknow?

Rereading feels like progress. Blurting and recall show you the truth.

Blurting

Notes closed. Write everything.

Dump what you remember into one box. The AI compares it to your notes, and what is missing is exactly what you study next.

Blurt · Cell division

Mitosis: prophase, metaphase, anaphase… then the cell splits in two.

Compared to your notes · 1 gap found: telophase
Recall

Or just say it out loud.

Press record, talk, press stop. The on-device AI transcribes every word to text, so your spoken recall is something you can work with.

Recall · PhotosynthesisRec0:42
Transcribed on your device

Photosynthesis happens in the chloroplasts and produces glucose and oxygen.

04 · Remember

Itallbecomesflashcards.

Spaced repetition decides when you review. The AI writes the cards so you never have to.

Spaced repetition

Graded once. Scheduled forever.

Tap Again, Good or Easy and the card comes back right before you would forget it. One day, three days, a week. No deck management, no guilt pile.

AI flashcards

You never write the cards.

Questions, answered.

Do I need an account to start?

Yes — a free account takes seconds and is free forever. It keeps your sessions safe and in sync on every device you use.

Is my data private?

Yes. Your data is stored securely in your account, and your stats are only ever visible to friends you approve. The AI runs entirely on your device — your notes never reach a cloud model.

What exactly is Synapzz AI?

A real language model that downloads once (about 800 MB) and runs entirely in your browser, on your GPU. It generates flashcards and powers recall tools. No cloud, no API key, and your notes never leave the device.

Is Pro a subscription?

No. Pro is a single one-time payment of $35. The AI, every Pro tool and all future updates are yours forever. No monthly fees, no renewal.

Does it work offline?

Sessions keep running through connection drops — everything is cached locally and syncs to your account the moment you're back online. The AI itself runs fully on your device, no connection needed.

Can I use it on my phone?

Yes. Synapzz is fully responsive and works in any modern mobile browser.
