## What the platform does
- Notes: up to 500 characters each, in a reverse-chronological log grouped by day
- Media: photos, video and audio. Attach, drag and drop, paste, record a voice note, or send from the share sheet when installed as an app. Tap a photo to open it full screen.
- Tags: type a word to make a chip, add more, or take suggestions based on the text.
- Filter: tap a tag to show only the notes that carry it
- Export: a button at the end of the log downloads a .zip with log.md and a media folder.
- Reserve your spot: enter an email to get on the list. Joining is the visitor's agreement to create an account when the list opens.
- Installable as a web app.
