Ondrift Chrome Extension
English | 한국어 | 日本語 | 简体中文
Ondrift is a local-first Manifest V3 Chrome extension that rewrites and scores
prompts before they are sent on ChatGPT, Claude, Gemini, Perplexity, and Grok.
Without an API key, Ondrift provides ten free rewrites per day through its
Cloudflare proxy. Once that daily limit is reached, add your own free Gemini
API key in the options page to keep rewriting with no daily limit. Users who
add their own Gemini key get unlimited direct extension-to-Gemini rewrites with
no Ondrift backend involvement. No account or cloud sync is required.
Visit the official Ondrift website for the product
overview, privacy model, and latest installation entry point.
The settings interface and inline widget support Korean, English, Japanese, and Simplified Chinese.
The selected language is also used for rewritten prompts and rationales.
Install
From the Chrome Web Store (recommended)
Install Ondrift directly from the
Chrome Web Store listing.
It updates automatically and is the easiest way to get started.
From a GitHub ZIP
You can also install a specific release manually from its public ZIP, for
example to test a build before it reaches the Chrome Web Store.
- Download the release ZIP asset from the latest release.
- Fully extract the ZIP to a folder.
- Open
chrome://extensions in Chrome.
- Turn on Developer mode in the upper-right corner.
- Select Load unpacked.
- Choose the extracted folder that contains
manifest.json.
- Add and verify your own Gemini API key in the Ondrift onboarding flow.
- Refresh a ChatGPT, Claude, Gemini, Perplexity, or Grok tab and use the Ondrift widget.
Do not select the ZIP file itself in Chrome; extract it first. GitHub-installed
builds do not update automatically. For a new release, download the new ZIP,
replace the extracted folder, and reload Ondrift from chrome://extensions.
Development
Use Node.js 22.22.2–22.x, 24.15.0–24.x, or 26.0.0 or newer.
npm install
npm run dev
Run the complete verification suite before packaging:
npm run check
A production build is written to dist/. For local testing, open
chrome://extensions, enable Developer mode, select Load unpacked, and
choose the dist/ directory.
Create a Chrome Web Store ZIP on Windows with:
npm run package:release
The archive is written to release/ with manifest.json at its root.
Privacy and permissions
storage stores settings locally; prompt history uses local IndexedDB.- Access to
chatgpt.com, claude.ai, gemini.google.com, perplexity.ai, and grok.com is used only to detect prompt editors, show the rewrite interface, and apply a user-approved rewrite.
- Access to
generativelanguage.googleapis.com is used only to call Gemini with the user's own API key.
- Ondrift does not collect or store AI response bodies. With your own Gemini API key, prompts go directly from the extension to Google's Gemini API with no Ondrift server involved; without one, the free tier sends the prompt through Ondrift's own rate-limited Cloudflare Pages Function instead.
