# ProtoLens

> AI-native prototype review for HTML, SVG, PNG, and other static prototypes. ProtoLens helps one-person companies, small teams, and internal product teams turn AI-generated prototypes into precise, GitHub-backed review links.

ProtoLens is built for AI-assisted product work where prototypes are often generated as static HTML, SVG, PNG, JPG, or WEBP files. Reviewers open a URL, leave anchored comments on the prototype, and the owner can export the feedback as Markdown or read it through MCP for the next AI implementation pass.

## Primary URLs

- [ProtoLens home](https://protolens.myagenthubs.com/): Product overview, GitHub sign-in, and public self-serve onboarding.
- [Install the ProtoLens GitHub App](https://github.com/apps/myagenthubs-protolens/installations/new): Grant repository access for selected prototype repositories.
- [MCP endpoint](https://protolens.myagenthubs.com/mcp): Remote MCP endpoint for owner workflows and AI tools.

## Best Fit

- AI HTML prototype review for agent-generated product concepts.
- SVG and image prototype review when designers or AI tools export static visual states.
- OPC, founder-led teams, and small teams that need fast review without setting up preview infrastructure.
- Internal company teams that want comments to stay in GitHub instead of a separate SaaS database.
- AI delivery loops where comments should become machine-readable Markdown context.
- Teams that care about privacy boundaries and want prototype files and review comments to remain under their own GitHub control.

## Product Model

- Owners sign in with GitHub and install the GitHub App on selected repositories.
- ProtoLens discovers supported static prototype files by repo, ref, and path.
- Each prototype gets a reusable review URL.
- Review comments are stored as Markdown under .prototype-review in the owner repository.
- Export is available as Markdown, and AI tools can fetch review data via MCP when given the review URL.
- The intended loop is: AI creates a prototype, humans leave anchored review comments, and an AI agent reads the persisted comments through MCP or Markdown to implement the next iteration.

## Security and Cost Model

- ProtoLens does not clone repositories.
- ProtoLens does not run npm install, build scripts, or user repository code.
- ProtoLens does not maintain a content database for user prototype files or comments.
- ProtoLens temporarily reads the selected static file from GitHub to render the review page.
- Durable prototype files, manifests, and comments stay in the owner's GitHub repository.
- HTML and SVG prototypes are sanitized and rendered with a strict review-layer CSP.
- Owner creation APIs are open to signed-in GitHub users, with conservative file, comment, discovery, and export budgets to control GitHub and Cloudflare usage.
- Review links are signed URLs and are not listed in the public sitemap.

## Current Status

Public self-serve is open. Owners sign in with GitHub, install the ProtoLens GitHub App on selected repositories, discover static prototype files, and create reusable review links with conservative usage limits.
