Its reviewed file, document, image, audio, video, connector, and MCP cells are scoped to that web surface and do not apply to the separate Grok Bot desktop-plus-cloud agent product. - HTML: https://canmyagentuse.com/harnesses/grok-web - JSON: https://canmyagentuse.com/api/v1/harnesses/grok-web.json - Markdown: https://canmyagentuse.com/harnesses/grok-web.md Grok appears here as a **Web** column so a capability page can show this harness next to others. This record covers the consumer browser chat at `grok.com`; it is separate from **Grok Bot**, whose desktop client controls persistent agents running on a hosted computer. Support cells for this surface are published only when a dated note cites reviewable public evidence; every other cell remains **unknown**. ## Exact surface - Family: Grok - Provider: xAI - Surface: web - Execution: hosted - Target type: hosted-observation - Default environment: hosted-default - Tracks: current, preview - Product site: https://grok.com - Brand reference: [Grok](/provider-marks#grok) ## Current support summary - Reviewed: 9/114 - Supported: 9 - Partial: 0 - Unsupported: 0 - Unknown: 105 - Not applicable: 0 - Unique public sources: 2 - Latest current evidence: 2026-08-28 ## Capability family summaries Family summaries are derived from atomic child records;
