A real feedback loop, start to finish

A reviewer left feedback on the exact HTML state. The owner turned it into a clean revision brief. The agent pulled it and published the next version on the same link.

4 versions · 2 review loops · 6 feedback items · 2 applied briefs

Everything after generation

Not another static host — the publish, share and feedback loop for agent-generated HTML.

One-line agent publish

Publish a single HTML or Markdown file, zip or directory from any environment via CLI / API / MCP, get links back as JSON.

Stable links · implicit versions

Every publish becomes v1 / v2 / v3; the latest link never changes and old versions stay viewable.

View / Feedback links

Viewers read cleanly, reviewers leave lightweight feedback — separate permissions and UI.

Precise feedback

Select text or click an image to pin feedback exactly; falls back to sections or the whole content.

Feedback loop

Export an Agent Feedback Brief in one click, or let the agent read it via API and ship the next version.

Access analytics

Views, devices, source and version split — know if a share actually landed.

A four-step loop

1

Agent publishes

Run publish in Codex / Claude Code / CI and get view and feedback links.

2

Confirm & share

Check it on desktop or mobile, copy a link to clients, execs or your community.

3

Collect feedback

Reviewers comment on the whole piece or a section — no signup.

4

Ship the next version

The agent reads feedback and generates v2; the link stays the same, pointing to latest.
