Every reply says what it saved

Type, record or photograph in the chat; the reply opens with a line for each thing it saved.

  • Hold to record, slide to cancel, or tap the camera.
  • One question per bubble; some come with buttons.
  • Up to 20 photos a message, each opens full screen.
  • People, Follow ups and More hold what it filed.

Plans are bought on the web

The app is for phones and in Beta; it sells nothing inside, and Settings exports your record.

  • Buy a plan on pricing or from Telegram.
  • Export everything in Settings: one JSON file of your record.
