Three kinds of engine

AI-powered tools (paraphrasing, grammar, summarizing, translation and most content tools) send your text to our server for transient processing; the result comes back and the text is discarded. Browser tools (spell checker, dictionary, word and character counters, readability checker, case converter, text compare, citation generator and the text utilities) run on your device, so the text never reaches our server; the dictionary only looks the word up on Wiktionary for its definition. The plagiarism checker sends a few short phrases to open sources and lists every source it searched.

English first, every language welcome

Tools start in English on this site. Switch the text language in the editor to work in another language: the AI tools are instructed to follow that language's own spelling rules, and each language edition of AdeptWrite adds its own spell checker where an open dictionary for that language exists.

Every core tool is free and needs no account. We do not show user counts or testimonials because we have no verified data yet; what we promise is tools that work exactly as described.

Frequently asked questions

Are all of these tools really free?

Yes. Every tool works without login. The only limits are the text length per run (shown in each AI tool, and higher on paid plans) and fair per-minute quotas that keep the service fast for everyone; browser tools have no quota at all.

Which tools work without sending my text to a server?

The Spell Checker, Word Counter, Character Counter, Readability Checker, Case Converter, Text Compare, Citation Generator and the text utilities run entirely in your browser. The Dictionary also checks words locally but fetches definitions from Wiktionary. The other tools use our server.

Do the tools work in languages other than English?

Yes. AI tools accept English and the other languages in the text-language list, and the translator works between 95 languages. The Spell Checker and Dictionary on this site check English; other languages have their own instances on their language editions, such as KBBI and EYD V on the Indonesian site.
