Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Antora

  • Content must be AsciiDoc, so an existing markdown documentation set has to be converted before you can evaluate the tool properly.
  • The component, version and module model must be understood before anything builds, and the first working site typically takes days rather than the afternoon a markdown generator needs.
  • Theming means building a separate UI bundle with Handlebars templates and its own pipeline, which is a front-end project most documentation teams are not staffed for.
  • There is no search included, so every deployment adds either a Lunr extension with its own index size limits or a paid hosted search service.
  • Builds fetch from every configured repository, so large multi-component sites become slow and depend on git availability during every documentation build.

Grammarly

  • Occasional false positives and grammatically incorrect suggestions that can introduce errors
  • Privacy concerns about sending text to Grammarly's servers for analysis
  • AI capabilities sometimes produce hallucinations and fabricated citations that appear grammatically correct

Answered from the vendors’ own pages

Antora: Can I use markdown with Antora?

Not as the primary format. Antora is an AsciiDoc pipeline, and treating markdown as a first-class input means a different tool.

Grammarly: Does Grammarly have a free version?

Yes, Grammarly offers a free tier with basic spelling, grammar, and punctuation checks, tone visibility, and 100 AI prompts per month. The Pro plan ($12/month annual) adds sentence rewriting, plagiarism detection, and 2,000 AI prompts.

Antora: Is it worth it for a single product with one version?

Usually not. The model pays off when you have several repositories or several supported versions; below that a simpler generator will do the same job with far less setup.

Grammarly: What platforms does Grammarly work with?

Grammarly works across 1 million+ apps including Google Docs, Microsoft Word, Outlook, Slack, Gmail, and web browsers. It also integrates with productivity tools like Asana, Jira, Monday.com, Confluence, and HubSpot.

Source
Antora: How does versioning actually work?

Each branch or tag of a source repository becomes a version of that component. You publish a new version by branching, not by copying a directory.

Grammarly: Can I use Grammarly offline?

Grammarly requires an internet connection to function, though the browser extension works with some offline text areas. For offline use, the desktop app and browser extensions sync when reconnected.

Source
Antora: Who maintains it?

OpenDevise, the group behind Asciidoctor, under the Mozilla Public Licence. Paid consulting and custom UI work are available from them separately.

Grammarly: What is included in the Enterprise plan?

The Enterprise plan includes unlimited team members, dedicated support, custom roles and permissions, data loss prevention, bring-your-own-key encryption, and unlimited AI prompts. Pricing is custom and available by contacting sales.
