About pheebo
AI makes mistakes, pheebo guards your back. Detects and solves mathematical expressions on ChatGPT and Claude AI.
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 to not trust 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 trust the LLM you are using, delegating to pheebo the task to check and signal you when and where an error appears!
pheebo comes with 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.
Automatic mode: our most advanced error detection engine, working in silence in the background, automatically spotting the errors.
