Espalier
A Procestra app

For writers, planners, and anyone who thinks better when they can see it.

Train your ideas
into shape.

A local-first bench for thinking spatially. Lay your ideas out as cards on an open surface, cluster them into stacks, and snap them into columns and rows. It's the stage after capture, when a pile of thoughts needs structure, sequence, and adjacency you can see.

Why it exists

Capture is easy; shape is hard. The move after a pile of ideas isn't another list. It's seeing how the pieces sit together, what clusters, what comes first. Espalier is a quiet bench for exactly that, where structure emerges from arrangement instead of an outline you fight to fill.

On the bench
Cards & stacks
Every idea is a card on an open surface. Drag them together and cluster the related ones into stacks you can collapse and expand.
Columns & rows
When a layout firms up, snap cards into neat columns and rows. One pass to clean up squares the whole board in a beat.
Boards you own
Each board is a local file, .bench or JSON, in a folder you control. Local-first, no account, nothing leaves your Mac.
Export the shape
Turn a finished board into an outline, Markdown, or PDF, and carry the structure into whatever comes next.
Works with Seed

Espalier boards fill with cards transplanted from your Seed garden. Capture loosely in Seed, then pull the ripe ideas onto the bench to shape them. Ideas begin in Seed and grow up in Espalier, though each app stands on its own.
