In their own words
GitBook
GitBook is a documentation platform for teams creating, reviewing, and publishing branded documentation websites. Content can be written in a block-based visual editor or Markdown, organized through branch-based review, or synchronized with GitHub and GitLab. Published sites support custom domains, responsive layouts, SEO, preview deployments, and site variants. GitBook Agent can surface documentation gaps, draft updates, and review changes, while GitBook Assistant answers questions using documentation and connected sources. Teams can set tiered permissions and restrict documentation to authenticated users. The Free plan is free, includes one user, and limits GitBook Agent to 10 messages per week. Premium is $65 a month billed per site annually, plus $12 per user/month; Ultimate is $249 a month billed per site annually, plus $12 per user/month. Annual billing includes two months free, and a 14-day trial is available. Published documentation traffic is not limited.
Pergamon
Pergamon generates regulation-based product manuals, labels, and related documentation from product specifications and reference materials. Its AI authoring agent accepts specifications, documents, videos, audio, and images to produce structured manual content, while more than 200 pre-built product blueprints offer structured starting points. Neural machine translation supports 30+ languages and is described as keeping terminology and regulatory structure consistent. Manuals can be exported as PDF, InDesign, HTML, or XML, with formats depending on plan. An optional AI Product Support Agent lets consumers and support teams scan a product and ask questions by voice or text, with answers drawn from its manual. Pergamon offers TMS and ERP/PIM integrations on Enterprise plans, plus API and bespoke integrations for Enterprise clients. It is hosted and runs on Linux, macOS, web, and Windows. Pricing starts at $49/mo; there is a 7-day trial and no free plan. The trial allows one manual with limited, watermarked exports containing partial pages. Pergamon says its data is hosted on AWS servers within the EU and encrypted at rest and in transit. It lists GDPR and ISO 27001 on all plans, while noting brands retain final responsibility for documentation compliance.
