How it works
From feedback to fix in three steps
Point at a problem, and our AI agent does the rest — no context-switching, no back-and-forth.
Annotate
Navigate to any page and click exactly where you see an issue. Add your feedback — text, screenshots, or recordings.
AI analyzes & fixes
The agent reads your annotation, clones the connected repo, finds the relevant code, and generates a fix in an isolated sandbox.
Review & ship
A draft pull request appears on GitHub. Review the diff, approve, merge — done. What took hours now takes minutes.
Platform

Annotation, collaboration, and AI-powered fixes — all in one platform.
Live Website Annotation

Click 'AI Fix' on any annotation. The agent finds the code and opens a PR with the solution.

FAQ
Common questions
How does the AI agent work?
Click 'AI Fix' on any annotation. The agent reads your feedback and screenshot, clones the connected repo into an isolated sandbox, locates the relevant code, generates a fix using Claude, and opens a draft pull request on GitHub — all automatically.
What languages and frameworks does the agent support?
The agent works with any GitHub codebase — React, Vue, Svelte, Angular, plain HTML/CSS, and more. If your code is in a GitHub repo, the agent can analyze and fix it.
Is my code safe?
Yes. Every agent run happens inside an ephemeral sandbox that is destroyed immediately after the fix is generated. No source code is stored. The sandbox runs with network isolation and never has access to your API keys or secrets.
Can external stakeholders leave feedback without signing up?
Yes! Create a share link for any markup project. Guests can view the page and leave annotations without creating an account. You control the permissions — view-only or comment-enabled.
What file types do you support?
Sitemarks supports live websites (any URL), uploaded images (PNG, JPG, WebP, SVG), PDF documents (multi-page), and videos (MP4, WebM). All with precise, contextual annotation.
Can I use my own API key?
Enterprise customers can bring their own API key (BYOT) for Anthropic or other LLM providers. This gives you full control over model usage, billing, and rate limits.
Stop describing bugs. Start fixing them.
Annotate, let AI fix, review the PR, and ship. Sitemarks turns visual feedback into merged code.
