One-time purchase, no subscription. Available on Mac and iPad (as Writer Studio Pro). ALWAYS private, nothing collected, ever!

Hi everyone — I'm a retired teacher, not a professional developer. I built Writer Studio through AI-assisted coding, working with Claude to write the actual code. I initially wanted a rewriting tool that would modernise an 80 year old text - but it grew way bigger than that. I also wanted an app that didn't lock me into a subscription for something I'd use occasionally, so that's what I built: pick your AI (free on-device Apple Intelligence, Google Gemini's free tier, or your own OpenAI/Anthropic key), pay once, done. It is NOT a subscription model. It does NOT collect/store anything externally - ever. Totally private to your machine! Over 17,000 combinations of altering your text! I am happy to answer anything — including about the AI-assisted build process, if that's interesting to anyone here.
