Piecerun

WHYWhat repeats is the brand, not the content

Where your brand's content gets made.

Pieces, a calendar, and an agent that works on its own. It already writes; in here it also designs, checks and schedules, without you opening a design editor once.

Only to tell you when it opens. Nothing else. Privacy

Why

Posting on social every day is worth nothing if every piece looks like a different brand

Nobody recognizes a brand because of one brilliant idea: they recognize it because they saw the same color, the same type and the same margin thirty times, under thirty different messages. That is exactly what breaks when every piece is generated from scratch.

And what slows you down is not running out of things to say: it is having to design them. That is why the agent here does not hand you an image to fix, it builds the piece against your brand kit and what comes out is already on brand.

How it does it

Three rules that are not up for discussion

Designs with code

Real type, a real grid, brand tokens. The same piece comes out the same twice, and a fix is applied to the file, not to a prompt.

The brand kit is in charge

No layer stores a color or a font: it stores a reference to the kit. Change one color in the kit and the pieces from six months ago get repainted too.

The linter measures the render

Literal color, literal font, contrast, how much text fits and what spills over: everything is measured on the drawn piece, not on the text.

The workshop

All the work, in plain sight

Feed, Stories, Calendar, Assets and Templates. Everything there is can be seen, opened and edited from the browser, with nothing to install.

  • The editor opens on Content: one field per text in the piece, with how much fits in each and what it is for. The design is one click away, but it never gets in the way of writing.
  • A piece is a file: a file of your own: open it, save it, version it.
  • Undo understands the gesture: five clicks on a field arrow are one step back, not five.
  • Calendar and approvals: what goes out, on what day, and who looked at it first.
Real pieces

Four pieces, one brand

Four different templates. The colour, the type and the sign-off are not up to each piece: they are loaded once in the brand kit and every template inherits them.

The agent

It works inside, not alongside

Your agent connects over MCP and works inside the workshop: it creates the piece, writes it, validates it, renders it and schedules it.

  • 35 tools over MCP: create, write, validate, render, schedule, translate and export.
  • Bring your own: Claude Code, Claude Desktop, Cursor or Codex. Piecerun ships no model.
  • You and the agent, at once: if you both touch the same piece at the same time, yours wins.
  • Your agent never queues: another account's work never slows you down, and yours never collides with itself.

Your model and your languages

The model bill is yours

The subscription pays for the platform. The agentic part is paid with your own credential, so the model bill is yours and no surprise shows up at the end of the month.

English, Spanish and Japanese

The original is written in English and the translations hang off it. If the original changes, the ones that went stale mark themselves.

No passwords

You sign in with Google or GitHub. Piecerun stores no passwords at all: the one who confirms it is you is your provider.

!

Piecerun exports the files and the captions ready to upload. Publishing is still done by hand, on purpose: as long as the last call belongs to a person, no piece ever shows up published without anyone having looked at it.
