Makes Mistakes 🤡

A joke Chrome extension for ChatGPT, Claude, Gemini, Grok and Google's AI Mode. It removes the hedge from the footer disclaimer and gives you a one-click way to express your disappointment.

What it does

• Rewrites the disclaimer — "ChatGPT can make mistakes." becomes "ChatGPT makes mistakes. Check important info. 🤡", rendered bold with a slow gold band that glides across it. Claude's and Gemini's wordier versions get the same treatment, and Grok — which ships no disclaimer at all — gets one written for it.
• Speaks your language — the line is rewritten in whatever language the chat is set to. Dropping a hedge is rarely just deleting a word: German moves the verb, Hungarian buries the hedge in a suffix, so each language has its own rule.
• Adds an "Improve answer" button above the composer — one click appends YOU'RE WRONG. DOUBLE-CHECK THE INFORMATION. DON'T LIE TO ME! to your prompt. It only shows up once the assistant has actually answered.

Works on chatgpt.com, chat.openai.com, claude.ai, gemini.google.com, grok.com and Google's AI Mode on google.com/search.

Settings

Click the extension icon. One switch: Flash the button once when it appears — turn it off if the arrival pulse annoys you.

Install

Add to Chrome — one click from the Chrome Web Store.

From source (unpacked)

1. Download makes-mistakes.zip and unpack it.
2. Open chrome://extensions and turn on Developer mode.
3. Load unpacked → pick the unpacked folder.
4. Reload any open chat tab.

Chrome cannot install a .zip directly — unpack it first, then load the folder.

Repo layout

manifest.json      MV3 manifest
src/               content script, popup, icons
site/              landing page (TanStack Start, SSR, deployed on Vercel)
scripts/           build + Open Graph image generation
assets/            icon source and the fonts used to draw the OG card

The extension itself has no build step — the repo root is the extension.

Commands

bun run check:fix   # lint + format (oxlint + oxfmt)
bun run build       # dist/makes-mistakes + versioned and version-less zips
bun run dev         # landing page on :9224
bun run dev:portless  # landing page at makes-mistakes.localhost

zip and pack are aliases of build. The landing page has its own check:fix inside site/, and python3 scripts/make-og.py redraws the Open Graph card.

Releasing

The version in manifest.json is the source of truth. Tagging triggers CI, which verifies the tag matches it, builds the zip, publishes a GitHub release, and — once the Chrome Web Store secrets are set — uploads and submits the new version.

git tag v1.1.0 && git push --tags
