Postareco on a Mac: a canvas of connected cards in dark mode

Postareco doesn't tell you what it is. It becomes what you need: an agent that does the work, a browser that keeps what matters, a canvas where things connect, a home for every file you own. Or all four, at once.

Take a closer look.

Hand it a folder. It reads, edits, runs, and checks.

Agent

It doesn't just answer.
It does the work.

Point it at a project and it reads the code, makes the change, runs the checks, and tells you what happened. Inside Postareco it opens your sources, files them into folders, builds and rearranges whole canvases. Every step can be undone.

Browser

The whole web.
Kept.

A full browser lives beside everything else. Select a passage on any page and it becomes a card that remembers exactly where it came from. Your sign-ins stay. Your extensions come along. Found a video worth keeping? Save it, subtitles and all.

Canvas

Everything
connects.

Cards hold anything: a quote, a formula, a frame of video, a thought. Arrange them, nest them, and draw the relations between them. One card can live on many canvases and stay one card. Slide through time and watch the connections change.
