Everything you hear, organized to study

Folio is built for students first — and anyone who needs to capture spoken content without sending it to the cloud.

Record in one tap

Capture full lectures with background recording, live waveform, and timestamp marks for important moments.

Clean transcripts

On-device speech recognition turns audio into searchable text with speaker-aware segments on supported devices.

Summaries & concepts

Premium unlocks AI-generated overviews, key takeaways, and concept chips — processed with Apple Intelligence on your phone.

Courses & library

Group recordings by course, filter your library, archive old lectures, and share study packages with other Folio users.

Flashcards & quizzes

Study from auto-generated cards and quizzes built from your own recordings — not generic web content.

Export & share

Share recordings and notes via AirDrop, export to text or PDF, and import .foliolecture files from friends.

Stays on your phone

Privacy isn’t a feature bullet — it’s how Folio is built. We don’t operate servers that receive your lecture audio.

No cloud uploads of audio

Recordings stay in local app storage on your iPhone.

No third-party AI APIs

Transcription and study features use Apple’s on-device frameworks.

No analytics on your content

We don’t sell your recordings or read transcript text for ads.
