Zetane

Document-heavy business writing is where this AI writing tool focuses, and Zetane is built around source files rather than blank-page drafting.

Zetane is a writing and editing tool that turns source documents into long compositions, runs deep research reports, and analyzes RFPs to write proposals.

It also offers chat, document Q&A, code help and image generation, plus 20+ agents and workflows that share a common resource pool.

The free Starter plan needs no credit card and includes about 100 assistant interactions, 3 long document compositions and 2 deep research reports.

Standard costs $59 per user per month and raises that to roughly 1,500 interactions, 6 RFP analyses, 9 long compositions, 15 research reports, 30 images and 3 GB of storage.

Professional is $200 per user per month with about 5,000 interactions, 20 RFP analyses, 30 compositions, 50 reports and 100 images.

Enterprise adds team sharing, access controls, custom integrations, tailored agents and dedicated support.

Usage figures are approximate, so check limits before you commit a team.
