The short version

  • Each has a real cost: Grammarly occasional false positives and grammatically incorrect suggestions that can introduce errors; Nuclino there is no publishing layer, so a public help centre or versioned product documentation cannot live here and has to be maintained in a second tool.
  • They diverge on capability: Grammarly covers Grammar checking, Nuclino covers Item graph.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

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

Nuclino

  • There is no publishing layer, so a public help centre or versioned product documentation cannot live here and has to be maintained in a second tool.
  • The free plan is capped at roughly fifty items, which a real team passes within weeks, making it a trial rather than a usable tier.
  • Per user pricing means occasional readers who open a document twice a month cost the same as the writers who maintain it.
  • The editor is intentionally limited, with no databases, relations or page-level templates, so structured content such as a request register needs a different product.
  • Export options are limited to Markdown and PDF per item, so moving a large workspace elsewhere is a bulk conversion job rather than a supported migration.

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
Nuclino: Where is the data stored?

In the European Union, by a company registered in Germany, which is usually the reason procurement shortlists it.

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
Nuclino: Does it handle translated content?

No. There is no locale model, so translations would be separate items kept in sync by hand.

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.
