FiftyGPT is an independent AI tools platform built around one idea: writing tools should be useful, fast, and honest about what they can and cannot do.
What we build
We offer a suite of free tools for everyday writing work — an AI detector, an AI humanizer, a paraphraser, a summarizer, a grammar and spell checker, a translator, a word counter, a citation generator, an email assistant, a resume helper and image utilities. Each tool is designed to do one job well, with a clean interface and clear results.
Our honesty principle
AI detection is probabilistic by nature. No detector on the market can prove with certainty that a text was written by a machine, and we refuse to pretend otherwise. Our detector always shows a confidence level alongside its estimate, explains the patterns it found, and reminds you that the score should never be the only basis for judging someone's work. When a tool needs an external data source that is not connected, we say so instead of inventing a result.
Privacy
Your text is processed to generate your result. Our usage statistics record counts and timings — not your content. Read the full details in our Privacy Policy.
Who it's for
Students checking their drafts, teachers reviewing submissions thoughtfully, writers polishing tone, marketers adapting copy, recruiters and job seekers, and developers who want the same capabilities through our API.
