PenPal is your voice-first notetaking pal. Just talk — PenPal records, transcribes, and turns what you said into clean summaries, to-do items, and calendar events, automatically. Spend less time typing and organizing, and more time thinking out loud. TRANSCRIBE ANYTIME — EVEN LOCKED Tap once and start recording. PenPal transcribes live and keeps going in the background, so you never lose a word — even with your phone locked or while you switch apps. SUMMARIES AUTOMATED Every recording becomes a clean, time-stamped summary organized by topic. Skim a 30-minute conversation in seconds and jump straight to the part you need. YOUR TO-DOS AND MEETINGS, HANDLED PenPal pulls the action items and meetings out of what you said — with due dates and times. Review the suggestions, accept the ones you want, and they land in your to-do list and on your calendar. SYNC TO YOUR REAL CALENDAR Accepted events sync to your Apple Calendar — and onward to the Google, Outlook, or iCloud accounts you already use. No extra setup. ASK YOUR NOTES ANYTHING Chat with your entire library. Ask "what did I decide about the budget?" and PenPal answers, citing the exact notes it came from. STAY ORGANIZED Folders, tags, favorites, and search keep everything findable. Tap any line of a transcript to jump to that moment in the audio. PRIVATE BY DESIGN Your notes live on your device.
