How the Expolita checker works
Expolita flags possible errors, explains each suggestion and leaves the decision to you. Automatic checking helps, but cannot replace expert proofreading.
Write the way you always do
When you pause, Expolita reads the paragraph you are in and underlines whatever deserves a second look. It never interrupts, never moves the caret and never touches the text.
The new proposal aim to make the process clearer.
Understand the rule
Every suggestion says what it saw and why. If you want the whole rule, “Understand the rule” shows it without taking you away from what you are writing.
The verb form 'aim' does not seem to match the subject 'proposal'.
Apply correctionEnter ↵Let it passYou decide every change
“Apply correction” writes the suggestion into your text and Ctrl+Z undoes it. “Let it pass” discards it. “My words” keeps the terms you use so they stop being flagged.

Catalan, Spanish, French and English.
Expolita recognises the language of your text by itself, or you fix it from the panel. In English it keeps United States conventions apart from British ones.

Privacy: your text is never stored.
The text you check travels encrypted to Expolita’s server, is processed in memory, and is discarded when the request ends. It is not written to a database, to files or to logs, and it is never used to train models.
- In memory, nowhere elseThe fragment is checked and discarded. No copy stays on the server.
- The least your account needsEmail, an Argon2id-protected password, your personal dictionary and your preferences. You can delete all of it from the extension.
- Fields it never readsPasswords, one-time codes and card details stay out of reach. It does not read the clipboard either.
- No ads, no analyticsNo tracking, no third-party SDKs, no data sold.
Install it and write the way you always do.
Expolita stays in the background until it is needed. And when it is, it tells you in the margin.
