Learn languages by living in them.

Nitido quietly improves your writing in any app on your machine — and turns every correction into practice you actually need.

How it works

Three steps, one keystroke.

Nitido sits next to whatever you're already typing in — email, chat, docs, code reviews — instead of asking you to switch to another tab.

01

Correct

Select text anywhere on your machine and press the hotkey. Nitido rewrites it in clean, natural language.

02

Annotate

A non-blocking popup shows what changed and why, side-by-side with your original.

03

Practice

Your real mistakes feed a spaced-repetition deck, so you work on the gaps you actually have.

Who it's for

For people who already live in another language.

You use a foreign language every day for work or study, and you want to stop guessing whether your writing sounds right.

  • Writing email, chat and docs in a second language all day.
  • Tired of pasting into a separate tool to check yourself.
  • Want feedback that compounds — not corrections you forget.

Stop guessing. Start noticing.
