Sotto

Sotto is a privacy-first voice memory app built for people who think out loud — founders, writers, researchers, and anyone with ideas and experiences they want to remember without breaking flow to type. You just speak naturally, and Sotto's AI turns scattered thoughts into organized, searchable memories you can come back to later. The product is opinionated about privacy: you choose between cloud transcription with Zero Data Retention (nothing is stored on third-party servers) or fully offline on-device transcription that never leaves your phone. Memories are kept locally in an encrypted database, so the user — not a cloud provider — owns the personal history. It's a calmer alternative to traditional voice notes and second-brain apps: instead of dumping raw audio into a folder you'll never revisit, Sotto structures speech into retrievable knowledge while keeping the privacy posture closer to a local journaling app than to a cloud SaaS.
