Yantra is your second brain โ€” a private place to capture what matters, find it again later, and act on it. Everything you save lives on your device. Capture, transcription, search, your calendar, tasks, and reminders all run on-device for free โ€” no account, no subscription, no server in the middle. Add your own AI key only if you want to chat with your notes or auto-summarize what you save; that's the only time anything leaves your phone, and it goes straight from your device to the provider you chose. CAPTURE ANYTHING โ€ข Voice memos, transcribed on-device as you speak โ€ข Quick text notes and a daily journal โ€ข Photos โ€” with on-device text recognition โ€ข Saved links โ€” summarized when you add an AI key โ€ข Meetings โ€” long-form recording with speaker labels TASKS, BUILT IN โ€ข Capture to-dos with a due date and priority โ€ข See what's Overdue, due Today, and Upcoming at a glance โ€ข Turn any note into tasks, or promote a meeting's action items to your list โ€ข Tasks show up in your Agenda and in Ask ASK YOUR NOTES (optional AI) Add your own Anthropic (Claude) key to chat with everything you've saved. Yantra finds the most relevant notes on-device and answers with citations back to your own words. Talk to it hands-free, or type. YOUR CALENDAR, BUILT IN See your agenda from any calendar on your iPhone (iCloud, Google, Exchange), and turn notes and action items into events. MEETING REMINDERS Get a heads-up the evening before, and again shortly before each meeting โ€” so you can review any notes you prepared. Yantra even tells you how many of your saved notes look related. All scheduled on-device. BRING YOUR OWN KEY (optional) The basics are free and on-device. For AI features, Yantra uses your own Anthropic key โ€” you pay the provider directly at cost, no markup, no middleman. Optional Deepgram and Sarvam keys unlock speaker-labeled meetings and Hindi/Indic speech. PRIVATE BY DESIGN โ€ข Notes and tasks stored only on your device โ€ข API keys kept in the secure Keychain โ€ข No tracking, no ads, no analytics โ€ข Export everything to a single file you control Your thoughts are yours. Yantra just helps you find them again โ€” and get them done.
