ThoughtDAG

A free, open-source infinite canvas that turns your conversations with AI models into an editable graph — so you can see, prune, and reuse exactly which parts of the conversation the AI is actually reading, instead of a single ever-growing chat thread.

Kloni is a keyboard-first mind mapping app for macOS that lets you sketch out ideas on a visual canvas and then turn them straight into a task list, all stored locally on your Mac.

Records and transcribes every meeting, audio file, or video straight on your Mac — no bot joining your Zoom call, no audio leaving your machine — then turns the transcript into a structured summary with action items, for free.

An iPhone app where you dump anything — a photo, a voice note, a screenshot, a bookmark — and find it later just by describing what it was about, no folders needed.

OpenMarkdown

OpenMarkdown is a tiny, instant-opening notes app that stores everything as plain text files on your computer — and it's built so an AI assistant like Claude can read and edit the same file right alongside you.

Routine

Instead of switching between a to-do app, a calendar and a notes app, Routine puts all three in one place and lets you talk to it — "remind me to call the plumber tomorrow" becomes a task without typing.
