Get feedback on sites and have GPT-6 Astra prep the fix
Build client websites. Get feedback on the page. Let GPT-6 Astra in Codex prepare the fix. Simple Commenter gives your agent the comment, screenshots, element details and captured JavaScript errors through MCP. You review and test the change, then ask the agent to reply and resolve the original comment.
Hey Product Hunt, Aleksander here, founder of Simple Commenter.
You build the client’s website. They leave feedback. Your AI agent prepares the fixes, and you review them.
That’s the idea behind our third launch. Simple Commenter already lets clients point at a page and leave a comment. For OpenAI Day, we’re focusing on the next step: bringing that feedback into GPT-6 Astra in Codex through our MCP integration.
Take a comment like “The Book a call button does nothing.” Alongside the comment, Astra can read available screenshots, element details and captured JavaScript errors. An error such as “openBookingModal is not defined” gives it a useful starting point. With your project open in Codex, it can inspect the handler and prepare a code change for you to review.
You review and test the fix, then ask the agent to reply and resolve the original comment. Your client keeps using the same simple commenting experience.
Astra handles the coding work in Codex. Our built-in developer briefs are a separate Claude-powered feature, and the MCP integration also works with Claude Code and Cursor.
Our Webflow and Shopify plugins are coming soon too.
Give it a try and let me know what you think.
Thanks, Aleksander

Simple Commenter AI was hunted by Aleksander Kaaberma.

Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
