Factful

Factful works as an integrated writing environment where you write and get your text checked in the same place.

Factful is an AI proofreading and grammar checker that reviews spelling, grammar and factuality across 100+ languages.

The factual check is the part that sets it apart from a plain spell checker, since it looks at whether a claim holds up and not only whether a sentence is correctly formed.

Suggestions come in two kinds.

Short-term ones fix the sentence in front of you.

Long-term ones are meant to help you learn as you work, so the same mistakes show up less often over time.

That makes Factful closer to a coach than a one-click corrector.

The language coverage is the practical draw if you write in more than one language or switch between them often.

Factful is pitched as something like Grammarly with a wider scope, though how well it handles each language is something you would want to test on your own writing.
