This matrix distinguishes supported behavior from provider-validated behavior and future plans. Media metadata, accessible content, and voice transcription are separate capabilities: support for one does not imply the others.
  • Supported: implemented and available without an additional provider-validation qualifier.
  • Validated: implemented and manually verified against the provider.
  • Preview: implemented, with provider validation or production gating still in progress.
  • Planned: a design target that is not available yet.
  • Not supported: unavailable in the current implementation without ruling out later adoption.
  • Not planned: outside the current product direction for that provider.
  • N/A: the feature does not apply to that platform.
¹ Ordinary X DMs are supported. Encrypted Chat is Preview.

Inbound media

See Media and attachments for an overview of inbound media. Provider pages for Email, Slack, Telegram Bot, and Twitter / X describe their exact support and limitations.

​
Outbound files

See the outbound file matrix for native delivery, link fallback, limits, and provider permissions. Outbound file delivery does not imply support for inbound file content.
