How it works

Your client clicks. You get a clear report.

And if you want — AI can already prepare the fix for you.

🖱️

Client visits staging

No signup. No app to install. The feedback button is already there.

📌

They click what's wrong

Pin a spot, highlight text, or click any element on the page.

💬

They type the fix

"Change this to say..." Plain language. That's it.

🤖

AI writes the code

Pensl finds the right file and writes the exact change.

✅

PR lands in GitHub

You review and merge — or let it auto-merge if confident.

Three ways your client can leave feedback

📌 Drop a pin

Goes to your inbox

Click anywhere. Type a note. Pensl takes a screenshot and sends everything to your dashboard.

✏️ Highlight text

AI fixes automatically
Get in touch → Book a free call
“Change this to say Book a free call”
→ PR opening in 3 seconds…

Select any text on the page. Type what it should say instead. AI finds it in your code and changes it.

🖱️ Click an element

AI fixes automatically
Selected
“Make this button bigger and yellow”
→ AI reviewing component…

Click any button, image, or section. Describe the change. AI knows exactly which component to edit.

What you get

Everything. In one place.

One line to install on any site

Works on Next.js, WordPress, Webflow, plain HTML — anything. Your clients see a small button and nothing else changes.

<!-- paste before </body> -->
<script>
  window.Pensl = { projectKey: 'pk_live_…' }
</script>
✓ Feedback button is now live

AI opens the pull request

Most loved

Connect your GitHub repo once. When feedback arrives, the AI reads it, finds the right file, writes the change, and opens a PR — before you've finished your coffee.

“

“We used to lose half a sprint to 'just small changes.' Now those close before I even read them. It's the closest thing to a self-running client relationship I've found.”

Markus B.

Founder, Studio Kiesel · Berlin

“

“My AI coding tool goes through the open feedback every morning and fixes what it can. I review the pull requests over coffee. We cut revision time by 70% in the first month.”

“

“Self-hosted was the dealbreaker for us. Our clients have strict NDAs. Pensl runs on our own server. None of their content ever leaves.”

Questions we get asked.

Honest answers.

Does my client need to sign up or install anything?+
No. The feedback button is already on their staging site. They click it, describe what they want, and hit send. No accounts, no apps, no training.
What kind of changes can it fix automatically?+
Text changes work every time — the client highlights what they want reworded, types the new version, and a pull request appears within seconds. For layout or visual changes, it sends a fix for your review.
What if the AI gets it wrong?+
Every fix has a confidence score. Below your threshold, Pensl waits for your review instead of touching the code. And it's all in Git — one revert and it's undone.
Where does my data live?+
On your server. Pensl is self-hosted — you run it yourself. We never see your client's feedback, your code, or anything else. Takes about 5 minutes to set up with Docker.
Can I use it with Claude Code, Cursor, or other AI tools?+
Yes. Pensl exposes all open feedback to your AI coding tool so it can read, fix, and close tickets on its own. Your agent can process the whole queue while you sleep.
How is this different from Marker.io or BugHerd?+
Those tools collect feedback beautifully. Pensl actually acts on it. Neither Marker.io nor BugHerd can write a code fix, open a pull request, or talk to your AI coding tool. They hand you a to-do list. Pensl closes it.
