Yantra: Second Brain

Yantra is your second brain — a private place to capture what matters, find it again later, and act on it. Now on iPhone and Apple Watch. Everything you save lives on your device. Capture, transcription, search, tasks and your calendar run on-device for free — no account, no subscription, no server in the middle. AI works with no key at all using on-device Apple Intelligence, or bring your own Anthropic, OpenAI or Gemini key for larger models. Then requests go straight from your device to the provider you chose. CAPTURE ANYTHING • Voice memos, transcribed on-device as you speak • Quick text notes and a daily journal • Photos, PDFs and scans — with on-device text recognition • Saved links, summarized for you • Meetings — long-form recording with speaker labels • Share anything into Yantra from any app APPLE WATCH • Tap to record a voice note, or dictate a quick text note, right from your wrist • Add the complication to start recording from your watch face • Notes land in Yantra on your iPhone, transcribed on-device YOUR DIGEST A short daily or weekly recap of what you saved, what's due, and older notes worth another look — on the Notes tab, as a widget, or as an optional notification.
