The six tools, one sentence each

VoiceInput
VoiceInput is a voice input method for macOS: hold Right Option to speak, release, and the text lands at your cursor while every sentence is kept as a searchable memory on your Mac; iPhone has a separate keyboard app. The free plan works out of the box and the local engines run fully offline.
ScreenNote
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
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
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
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.
Filewise
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.

ONE KIT

Different jobs,
the same principles.

Each one focuses on a single job, and they don't share data; but they all follow the same principles — which is why you can pick up one after another with confidence.

Local-first

OCR, transcription, and search all run on your device. Your data stays yours.

Fits your habits

Screenshotting and talking are things you already do; the tools just save you a step.

Findable again

What you save is filed by why you saved it, so one word brings it back.

Better with use

Correct it once and it remembers; the sorting fits you more and more.

Pick one. Start now.

Each tool handles one situation — free, local-first. Just start with whatever's bugging you most.
