A free AI document editor that also works offline

Yes. ZET Mindshare includes the Zeta AI assistant on its free tier: chat, document editing and drafting. The free tier is not a trial — it has no time limit and asks for no credit card. It gives 30 documents, 30 notes, 40 credits and 100,000 tokens per day, and 500 MB of storage.

For most documents, yes. It has tables, charts, footnotes, a table of contents, columns, margins, page numbers, watermarks, digital signatures and PDF import and export. What sets it apart from Word is that nothing needs installing, and from Google Docs that the AI assistant is built in and the editor keeps working offline.

Yes. Documents are stored on your own device first, so they open and edit on a plane or with no signal. They sync once the connection returns.

Judge evaluates business plans, projects and ideas against criteria and writes its findings with reasons. Most assistants soften when you push back; Judge changes its verdict for evidence, not for pressure. An appeal without proof is rejected, and concrete proof genuinely moves the score.

Free tier: $0, forever. Pro: $14 a month or $140 a year, with a 7-day free trial. Creative Station: $40 a month or $400 a year, which covers every ZET app including ones released later. One-off credit packs start at $3.

The interface is available in 10 languages: English, Turkish, German, French, Spanish, Arabic, Russian, Japanese, Korean and Chinese. Most of this website is in Turkish; this page is the English summary.
