Grok vs Onyx

Grok is an AI assistant for chat, research, writing, and problem solving, available on Android, iOS, web, and through an API. It searches the web and X in real time and provides citations from web sources. Users can upload PDFs, images, spreadsheets, code, and audio for analysis, extraction, and summarization. Grok Imagine generates and edits images and video from text prompts or reference photos, while voice mode supports natural, low-latency conversations. Built-in connectors cover Gmail, Google Calendar, Google Drive, OneDrive, Outlook, Microsoft Teams, SharePoint, and Salesforce; custom MCP servers must be publicly reachable. Team workspaces and app integrations are listed. The Free plan costs nothing. SuperGrok costs $30 a month, and SuperGrok Plus costs $100 a month.

Onyx connects enterprise knowledge so people and AI agents can use relevant context in answers. It searches indexed sources in parallel and presents documents while enforcing each source's permissions. More than 50 connectors sync connected tools in the background and support hybrid semantic and keyword search. The Business plan lists chat and search, major LLM access, custom agents, MCP/OpenAPI actions, web search, deep research, code interpreter, and image generation. Business costs $20 a month, billed annually at $20 per user per month, for teams of any size, with 40+ app connectors and Community Support. Onyx provides APIs for messages, agents, LLM management, actions, and user authentication. Slack integrations can provide responses and agents; Microsoft Teams and Zendesk are described as coming soon. Deployments can run in a customer's cloud or on bare metal, including on-premise and fully air-gapped environments. The site says documents and embeddings can remain in customer infrastructure, data is not used for training, and permissions are checked at query time. Native Windows, macOS, and Linux apps connect to an existing deployment.
