PolitePost solves a very specific and very common problem: writing an email that says what you actually mean without sounding rude, unprofessional or unhinged. You drop your unfiltered draft into the box, press the button, and the service sends the text through a large language model that rephrases it into measured, collegial language suitable for an office inbox.
The project is deliberately small and transparent. Its About page publishes the actual monthly inference bills the site has paid since December 2022 and explains that it runs on Together AI's inference platform after moving through Anyscale, Microsoft and OpenAI over the years. The site states that it does not store or cache your text and acts only as a middleman, and that inputs are capped at 2,000 characters to keep costs predictable. Rather than charging users, it relies on optional coffee donations.
That model has proven durable: the operators have kept the service online for years and even spun off a companion Microsoft Word add-in called ConcisePost for editing documents in place. If you want a quick sanity check on a frustrated draft before you hit send, PolitePost is about as frictionless as it gets.
