AI marks

Matrix ecosystem

The Matrix ecosystem at a glance

345 clients, servers, bots and bridges, compared by what they do, how alive their development is, and how they treat AI: what they say about AI-made contributions, whether their developers use AI tools, and whether the product ships AI features.

The AI marks switch. In the header, AI-wary marks AI use with a red cross and “none found” with a green check; AI-friendly does the reverse; Neutral shows plain marks. It only changes the marks, never the data or the order. Your choice is remembered on this device.

AI across the ecosystem

AI policy

What the project says about AI-made contributions

  • Banned (fits the chosen stance)(against the chosen stance) 9
  • Restricted (fits the chosen stance)(against the chosen stance) 40
  • Allowed (fits the chosen stance)(against the chosen stance) 3
  • Encouraged (fits the chosen stance)(against the chosen stance) 1

AI in development

Whether the developers use AI tools on the repository

  • None found (fits the chosen stance)(against the chosen stance) 273
  • Config only (fits the chosen stance)(against the chosen stance) 6
  • Occasional (fits the chosen stance)(against the chosen stance) 40

AI in the product

Whether the product itself has AI features

  • None found (fits the chosen stance)(against the chosen stance) 324
  • Optional (fits the chosen stance)(against the chosen stance) 7
