ChatGPT Company Knowledge vs Claude: How to Make AI Know Your Company (2026)
Comparison · October 2026 · 4 min read
TL;DR
ChatGPT company knowledge, launched by OpenAI in October 2025 for Business, Enterprise and Edu plans, lets ChatGPT search connected apps such as Slack, SharePoint, Google Drive and GitHub and answer with citations and each user's permissions. Claude offers the same idea through Projects, enterprise search on Team and Enterprise plans, and remote MCP connectors. Both work by searching your tools when you ask. Neither keeps a record of what your company decided, notices when a decision changes, or shares that context with other AI tools. Sentra is the managed organization memory that does: it captures decisions and commitments from Slack, email and meetings, keeps each fact with its source and date, and gives the same memory to Claude, ChatGPT, Cursor and your own agents over MCP. In short: Sentra makes Claude, and ChatGPT, know your company.
What is ChatGPT company knowledge?
OpenAI introduced company knowledge on 23 October 2025 for ChatGPT Business, Enterprise and Edu.
- How it works: a version of GPT-5 searches several connected sources and answers with citations, respecting each user's existing permissions.
- Connectors: examples include Slack, SharePoint, Google Drive, GitHub, HubSpot and Intercom, plus custom apps built with MCP.
- How you use it: it is now a plugin, invoked with @Company Knowledge or from the tools menu, according to OpenAI's help center.
- Admin controls: Enterprise and Edu admins control access with role-based permissions.
How Claude knows your company
- Projects: a shared knowledge base and instructions per project, which Team and Enterprise members can share with view or edit rights.
- Enterprise search: on Team and Enterprise plans, owners connect a documents source and a chat source, and Claude searches them through MCP. Anthropic says no data from connected services is indexed in its systems.
- Custom connectors: any remote MCP server can be added, on all plans, and Research can call connector tools during a task.
- Claude Code: reads repository files and CLAUDE.md, and can connect to MCP servers for company context.

ChatGPT company knowledge vs Claude vs a company memory
| ChatGPT company knowledge | Claude (Projects, enterprise search, connectors) | Sentra company memory | |
|---|---|---|---|
| How it knows the company | Searches connected apps when asked | Searches connected apps or project files when asked | Captures facts continuously from Slack, email, meetings and tools |
| Knows what changed | No; finds the newest document | No | Yes; each fact has a time range and what replaced it |
| Captures meetings and decisions | Only if written in a connected app | Only if written in a connected source | Yes, including meeting notes and commitments |
| Works across AI tools | Inside ChatGPT | Inside Claude | Claude, ChatGPT, Cursor and custom agents over MCP and REST |
| Permissions | Each user's app permissions | Each user's connector permissions | Carried from each source tool |
| Best for | Teams standardized on ChatGPT | Teams standardized on Claude | Companies using several AI tools and agents |
The difference that matters: assistant search answers the question you asked from what was written. A company memory also answers the questions you did not know to ask, such as whether the plan you are about to act on was changed on Thursday.
How to make Claude know your company
1. Connect Sentra as a connector. In Claude Code it is one command: claude mcp add --transport http sentra https://api.sentra.app/mcp/. In Claude on the web or desktop, add Sentra from the connector list or as a custom connector at https://api.sentra.app/mcp/.
2. Authorize once. Claude reads company memory with your own permissions.
3. Ask about decisions, not documents. For example: what did we agree with this customer, and has it changed since?
The step-by-step guide to connecting Claude to organizational memory over MCP covers every client and the admin rollout.
How to make ChatGPT know your company
- Start with company knowledge for search across the apps ChatGPT connects to.
- Add a company memory over MCP so ChatGPT works from the same current decisions and commitments as your other tools.
- Keep one source of truth for both assistants, so a ChatGPT user and a Claude user get the same answer.
