Browser integration

Chrome extension

Optimize and improve prompts directly inside your browser. The extension reads the prompt you are writing in ChatGPT, Claude, or Gemini, shows what is unclear or sensitive, and writes an improved version back when you ask.

  • Manifest V3
  • On-device by default
  • Load unpacked

What it does

The extension puts the PromptFlowEngine engine next to the chat box you already use. A launcher button opens a side panel beside the conversation. From there you can analyze the draft, restructure a loose request into sections, remove filler, or redact secrets, and insert the result back into the chat.

By default everything runs on your device with the engine bundled into the extension. It reads the prompt box only, not the conversation, cookies, or anything else on the page, and it does not store prompt text.

It is not on the Chrome Web Store yet. Until it is listed, you build it from the repository and load it unpacked, which takes a few minutes and is described in the documentation.

Practical example

What happens when you click Restructure

The request on the left is what a developer might type into a chat box. The prompt on the right is what the engine returns, generated when this page was built.

What the AI gets

100/100
## Role
Act as a senior Python engineer.

## Requirements
- Handle bad rows.
- Follow the conventions, naming, and structure already used in the codebase.
- Handle invalid input and failure paths explicitly.

## Constraints
- Do not change unrelated code, and do not add dependencies unless the task requires them.
- Keep existing public interfaces and API contracts unchanged.

## Technical requirements
Stack: Python. Use it; do not introduce alternatives.

## Testing
- Add tests for the new behavior, including failure paths.
- Run the existing test suite and report the result.

## Acceptance criteria
- The new behavior works as described in the objective.
- All tests pass and no unrelated files are changed.

## Expected output
- Write a Python script that reads a csv of orders and emails a summary every morning.

Computed by the engine when this page was built. Every added line is labeled as engine guidance in the interface, so you can delete what does not apply.

Frequently asked questions

Is the PromptFlowEngine Chrome extension on the Chrome Web Store?

Not yet. Until it is listed, build it from a checkout of the repository and load it unpacked from chrome://extensions with Developer mode on.

Which sites does it support?

ChatGPT, Claude, and Gemini are supported directly. On any other page with a text box, click the toolbar icon, or paste a prompt into the panel.

Can the extension read my conversations?

No. It reads the prompt box only, after you open the extension on that page. It requests no host permissions and stores no prompt text.

Does it work in Edge or Brave?

It works in Chromium browsers that support Manifest V3 side panels.

Every product runs the same engine, so they combine without surprises.
