Kalpa is a second brain for everything people tell you. Let it listen through your day on iPhone, Apple Watch or AirPods, and it remembers who said what, what you promised and what they owe you. No new gadget to buy. Later, just ask: "What did Andrew and I agree on last time?" Kalpa answers from your own recordings and shows the conversation the answer came from. REMEMBERS PEOPLE - Everyone you talk to, sorted by person: clients, family, friends - What you owe them and what they owe you - What is worth asking about next time, like a birthday or a new job EVERY PROMISE, KEPT - Commitments are caught in conversation, yours and theirs - Today shows what needs you, with one tap to mark it done - Prep for a meeting with a brief of unfinished business (paid plans) JUST ASK - Chat with everything you have recorded - Every answer links back to the recording it came from - AI summaries, key points, decisions and open questions for each recording - Topics sort themselves: projects, trips, family, health RECORD ANY WAY YOU LIKE - A sound recorder on iPhone and Apple Watch: tap record, keep it going with the screen locked - Voice notes, voice memos, meetings, lectures, interviews and brain dumps - Import audio and video files, or paste a podcast or video link - Share a voice message or video to Kalpa from any app PRIVATE BY DESIGN - Kalpa transcribes speech to text on your iPhone in 25 languages and switches on its own - Your recordings never leave your phone. Only the text syncs, so you can ask about it - For links, Kalpa keeps the transcript, not the media - Delete your account and everything in it from Settings MADE FOR - Founders and managers: meeting notes and follow-ups without a note taker in the call - Students: record a lecture, ask it questions later - Doctor visits and caring for family: remember what the doctor said and what to do next - Busy and ADHD brains: brain dump by voice, find it when you need it - Journaling: keep a voice journal or diary, a lifelog to look back on your days FAIR PRICING Start free.
