Gatheon · product family
Gatheon is a family of small iPhone and Mac tools that make the screenshots, voice and files you save offhand findable and usable. There are seven today: ScreenNote, SnapCal, ScreenStack, Shotbox, VoiceInput, Twinsubs and Filewise; pricing and privacy are set on each product's own site.
Each one does one job with a screenshot: keep it as a note, turn it into an event, clean it up, or find it again on a Mac.
ScreenNote is a screenshot notes app for iPhone and Mac that keeps what is inside your screenshots: it reads the text on the device, logs payment screenshots as expenses, creates to-dos automatically and finds the original from one word. Core features are free, no account, and with AI off nothing leaves your device.
SnapCal is a schedule-reading app for iPhone that turns screenshots of chat messages, posters and meeting notices into calendar events, then writes them to Apple Calendar and Feishu once you confirm. The free plan includes 10 reads a month; a subscription or a one-time lifetime membership unlocks unlimited use.
ScreenStack is a screenshot manager for iPhone: it sorts screenshots by purpose, makes codes and order numbers searchable and copyable with on-device OCR, and shows a receipt before anything is deleted. It manages the screenshots themselves and does not turn them into notes. Core features are free; Pro is a one-time purchase.
Shotbox is a menu-bar screenshot tool for macOS that lets you find any screenshot again from one word: after each capture it reads the text on your Mac, titles the shot and files it automatically. It is free, needs no account and works offline, and screenshots and their text never leave your device.
Speech becomes text; whatever plays becomes bilingual captions.
VoiceInput is a voice input method for macOS: hold Right Option, speak, release, and the text lands at your cursor. Free to start; local engines run offline.
Twinsubs is a Mac app that live-translates the sound your computer plays and turns video and audio into bilingual SRT subtitles, all on-device, no upload.
Downloaded files get renamed and filed by what is inside them.
Filewise is a file organizer for Mac that reads what is inside your files: downloaded PDFs, invoices, screenshots and scans are renamed clearly and filed where they belong by a local AI. It runs fully on the Mac, never deletes files and makes every step undoable; free to download at present.
