Pheebo is a Chrome extension that checks the calculations of your AI. Using it, you don’t disrupt your workflow by turning to external math solvers, or continuously asking ChatGPT to use Python for math. Available in: - Selection mode: click & drag to create a frame around the formula or computation that you want to check and let pheebo give the right answer (free). - Automatic mode: our most advanced error detection engine, working in silence in the background, automatically spotting the errors (paid).
What to expect from an ideal product
- pheebo catches silent math mistakes that ChatGPT makes without warning, so you stop shipping reports, spreadsheets, or decisions built on wrong numbers.
- No tab switching, no copy-pasting into Wolfram Alpha: pheebo checks AI calculations directly inside your browser while you stay in your actual workflow.
- The free Selection mode lets you drag a frame around any formula or result and get the correct answer in seconds, no account required to get started.
- Automatic mode runs in the background across your entire session, flagging arithmetic and calculation errors before you even notice them yourself.
- If you rely on ChatGPT, Gemini, or Claude for anything involving numbers, pheebo works like a silent spellchecker that only speaks up when the math is wrong.
