DeepDoc vs Pergamon

DeepDoc turns a code repository into a navigable documentation site, regenerating pages affected by code changes through its update command. It scans source files, plans and generates documentation, stages OpenAPI references when present, and builds a site organized around topics such as architecture, endpoints, integrations, and schemas. Its AI answers can cite repository file paths and line ranges. Listed inputs include Python, TypeScript, JavaScript, Go, PHP, Vue, GraphQL, and OpenAPI or Swagger specifications. Output options include Markdown, Mermaid diagrams, a MkDocs Material site, a static Next.js/Fumadocs site, and an interactive API reference. Generated sites can include navigation and search, with an optional AI chatbot widget. DeepDoc is a terminal-based Python package requiring Python 3.10 or later; the maker says it needs no account or cloud service and identifies it as MIT licensed. Users bring their own LLM provider. Generate and update call that provider, so costs depend on the chosen model and documentation pages; other listed commands do not call an LLM. The deploy command produces a static site for any host.

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.
