Nitido
Private beta

Learn languages by living in them.

Nitido is a desktop and mobile app that quietly improves your writing in any application — and turns every correction into practice material.

How it works

  1. Correct. Select text anywhere on your machine, press the hotkey — Nitido rewrites it in clean, natural language.
  2. Annotate. A non-blocking popup shows what changed and why, side-by-side with the original.
  3. Practice. Your real mistakes feed a spaced-repetition deck, so the gaps you actually have are the ones you work on next.

Who it's for

People who already use a foreign language every day for work or study, and want to stop guessing whether their writing sounds right. Nitido sits next to whatever you're already typing in — email, chat, docs, code reviews — instead of asking you to switch to another tab.
