LLMs, such as ChatGPT, are not designed to perform computations or mathematical operations but they don't refuse doing it, introducing errors that can be catastrophic if the users cannot find them. Many experts suggest not trusting them with these types of tasks... But why shouldn't you? AI is correct most of the time, until an error appears. With pheebo, you can go back to trusting the LLM you are using, delegating to pheebo the task to check and signal you when and where an error appears! pheebo comes in two modes: - 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 - perfect for quick verification and spot-checking (FREE - No Account Needed). - Automatic mode: our most advanced error detection engine, working in silence in the background, automatically spotting the errors and highlighting math expressions as you read; ideal for intensive study sessions and research (PRO - Subscription). TIP: Ask ChatGPT or Claude to "show steps" or "show all computations" for better result. HOW TO USE 1. Install pheebo (no signup required for Selection Mode) 2.
