Peep the chick mascot

The file browser for
the AI generation.

Your OS shows you filenames. OpenPeep gives every file its own app.

Get OpenPeepView on GitHub

AI generates 30 files. You preview them one at a time.

Your JSON config is a wall of text. It could be an editor.

Quick Look can’t show you what matters. Context can.

Every project folder is just… a folder.

Every file type deserves its own app.

Peeps are mini-applications that live inside your file browser. They don't just preview files — they understand them.

Edit

Not plugins. Workflow apps.

A Peep can view, edit, generate, validate, and claim entire project folders. Here's what that looks like.

ViewEditToolsVerifyBundle

Poll Studio

A JSON config becomes a visual editor.

  • Content matching recognizes {"type": "poll"} — not just the file extension
  • Visual editor with live preview replaces raw JSON editing
  • Click "Generate" → server-side tool creates 1080×1080 images
  • Verify checks option count, caption length, image dimensions before export
  • One config file. One Peep. An entire creative workflow.

Episode Planner

A folder becomes a production dashboard.

  • Bundle matching claims folders with episode.json + scripts/ + assets/
  • See your script, assets, and exports in one unified view
  • No more digging through nested folders to find what you need
  • The folder IS the app. The Peep IS the workflow.

Your Custom DSL

Any JSON schema. Your own mini-app.

  • Define a custom JSON format for your team’s workflow
  • Build a Peep that renders it as a purpose-built UI
  • Content matching inspects JSON fields to auto-detect your format
  • Ship it on PeepHub. Now everyone on your team has the same tool.
  • This is what "extensible" actually means.

PeepHub: An app store for your files.

Every Peep on PeepHub is a new superpower. Install one, and your file browser learns a new trick.
