# HeyBrain > HeyBrain is an AI knowledge workspace for individuals, teams and their agents. This index links to product information, current pricing, setup guidance, comparisons and editorial resources. Use the current integration pages and your workspace to check availability before planning a connection. Setup guidance is client-specific; an MCP connection does not by itself establish permission inheritance, source write-back or universal memory across clients. ## Key pages - [HeyBrain MCP](https://heybrain.io/mcp): connection and access guidance -

Does it support the answer?](https://heybrain.io/blog/ai-hallucination-company-data): Open the link, then compare the claim with the passage. Those are two different checks. - [AI pilot evaluation: count the work after the draft](https://heybrain.io/blog/ai-for-executives): Ten briefings take 200 minutes manually and 210 with AI. The next decision needs more than a faster draft. - [Inconsistent AI answers: compare the inputs before changing the prompt](https://heybrain.io/blog/ai-inconsistent-answers): Two different sentences can be equally right. Two different routing decisions need a closer look. - [Context engineering: a complete AI briefing, from sources to draft](https://heybrain.io/blog/context-engineering): A complete fictional briefing and customer email, with every required fact visible. - [What is an AI brain? Follow the source to the answer](https://heybrain.io/blog/what-is-an-ai-brain): For company knowledge, “AI brain” usually points to a system that helps an assistant find and use relevant information. The label matters less than the source-to-answer path. - [Design a company AI knowledge system around one answer](https://heybrain.io/blog/build-a-company-ai-brain): Before you connect the whole company, decide exactly which answer the first version must get right. - [AI brain vs second-brain tools: choose for the work and the readers](https://heybrain.io/blog/ai-brain-vs-second-brain-tools): Your private notebook and the team’s approved reference do not have to live in the same system. - [How AI knowledge access works: identity, permissions and retrieval](https://heybrain.io/blog/how-an-ai-brain-controls-access): Logging in establishes an identity. It does not grant that identity every document in the index. - [What is an agentic brain? A practical map of the parts](https://heybrain.io/blog/what-is-an-agentic-brain): “Agentic brain” is an informal label for several parts working together. A component map is more useful than treating it as one mysterious intelligence. - [AI brain, agent brain and AI mind: translate the labels into components](https://heybrain.io/blog/ai-brain-agent-brain-ai-mind-glossary): Ask what persists, what gets retrieved and what can act. The metaphor alone will not tell you. - [AI knowledge access: a five-check permission test](https://heybrain.io/blog/secure-ai-brain-company-knowledge): A refusal can still leak a document title. Check what the reader receives, not just the answer’s tone. - [AI agent brain: follow one decision from request to result](https://heybrain.io/blog/ai-agent-brain): An “AI agent brain” is a useful metaphor only if it helps you follow a decision. Here is one request, the evidence it needs and the point at which the agent must ask for help. - [YC’s company-brain thesis: turn know-how into usable instructions](https://heybrain.io/blog/yc-company-brain-bet): The interesting part of YC’s company-brain request is what happens after the system finds the information. - [Company knowledge maturity: assess five capabilities, not five tools](https://heybrain.io/blog/company-brain-maturity-model): A well-run wiki can be more dependable than a badly run AI assistant. - [Institutional knowledge loss: separate missing answers from hard-to-find ones](https://heybrain.io/blog/institutional-knowledge-loss-cost): A better search tool cannot retrieve a decision nobody recorded. - [Governed vs verifiable AI: check the rule and the receipt](https://heybrain.io/blog/governed-vs-verifiable): A contractor asks an assistant for a restricted budget. The answer says “access denied”, and the dashboard shows a matching event. That is encouraging. It still leaves two questions: did the system actually withhold the budget, and can the event be checked later? Governance and verification address different parts of that investigation. - [On-chain audit anchoring: what a hash can prove](https://heybrain.io/blog/on-chain-audit-anchoring): An auditor receives a log on Friday. The operator says it is the same log that existed on Monday. An earlier cryptographic commitment can help check that claim. It cannot tell the auditor whether Monday’s log was accurate or whether requests were missing before the commitment was created. - [C2PA content provenance: what a valid credential tells you](https://heybrain.io/blog/c2pa-content-provenance): A supplier sends a photo labelled “tested at 120°C”. Its Content Credential validates. Can you publish that temperature claim? Not on that evidence alone. The credential may help you inspect who signed information about the image and whether the asset matches it. The test result still needs supporting evidence. - [Shared memory for multi-agent teams: handle a conflicting update](https://heybrain.io/blog/multi-agent-shared-memory): Two agents can read the same information and still overwrite each other’s work. Shared memory needs a rule for accepting changes, not just a place to put them. - [A knowledge base through MCP: trace one search from request to source](https://heybrain.io/blog/mcp-knowledge-base-for-agents): MCP can expose a knowledge tool to an AI application. The useful result is a traceable piece of evidence—not a promise that every source or permission is automatically connected. - [Use Notion pages in HeyBrain: connect, import and check your first answer](https://heybrain.io/blog/connect-notion-to-ai-agents): Import one approved Notion page, check its answer and decide how to keep the copy current. - [Give ChatGPT company knowledge: choose the right source route](https://heybrain.io/blog/give-chatgpt-company-knowledge): First decide whether ChatGPT needs a selected snapshot or a way to retrieve changing sources. The right route depends on the task, your workspace and the access you can actually verify. - [Choosing an AI second brain for a team: start with the shared work](https://heybrain.io/blog/best-ai-second-brain-for-teams): The best fit depends on what the team shares: files, a working wiki, structured records or notes an assistant can retrieve. Start there before comparing feature counts. - [AI knowledge management in 2026: improve one answer path first](https://heybrain.io/blog/ai-knowledge-management-2026): A useful AI knowledge-management project starts with a question people repeatedly struggle to answer. Give that question a reliable source path before expanding the system. - [Accountable AI memory: what your evidence actually proves](https://heybrain.io/blog/accountable-ai-memory): An AI memory system needs a way to explain what happened. The difficult part is stating exactly what its records establish—and where the evidence stops. - [AI second brain: a three-note workflow for your next draft](https://heybrain.io/blog/ai-second-brain): For a solo writer, a useful knowledge base ends with something you can use. - [Second-brain apps: choose the workflow you will actually reuse](https://heybrain.io/blog/best-second-brain-apps): The best second-brain app is the one that helps you turn saved material into useful work. Choose the moment of reuse before choosing the capture interface. - [Setting up AI memory: plan one capture-and-recall path](https://heybrain.io/blog/how-to-set-up-a-brain-for-ai): Start with one useful record and one client. Decide what is saved, who may read it and how you will know that the next session retrieved the intended record. - [Claude Code persistent memory: choose a route and verify the read](https://heybrain.io/blog/give-claude-code-persistent-memory): Claude Code already has persistence mechanisms. Start by choosing what should carry forward, then verify where a fresh session actually gets its information. - [Agent memory layers compared: Mem0, Zep, Letta, Cognee and LangMem](https://heybrain.io/blog/agent-memory-layers-compared): Choose an agent memory layer by the information you need to preserve and change. A preference record, a changing relationship and a shared working file are different jobs. - [Enterprise AI knowledge systems: five requirements to establish](https://heybrain.io/blog/enterprise-ai-brain): “Enterprise” should describe the requirements your system meets, not the confidence of its sales copy. - [From personal notes to team knowledge: what actually needs to change](https://heybrain.io/blog/personal-second-brain-to-enterprise-ai-brain): The first shared note needs an owner and an audience. It does not automatically need a new platform. - [AI brain tools for companies: build a shortlist around your sources](https://heybrain.io/blog/best-ai-brain-tools): Choose a company knowledge tool by the sources it must reach and the team that will operate it. A long feature matrix is useful only after those two questions are clear. - [How to choose an AI brain tool: seven questions to demonstrate](https://heybrain.io/blog/how-to-choose-an-ai-brain-tool): A useful evaluation turns each buying criterion into something a vendor can show. Keep documented capabilities, observed behavior and unresolved requirements separate. - [AI knowledge base security checklist: leave with a decision](https://heybrain.io/blog/ai-brain-tool-security-checklist): A policy, a demo and an assurance report answer different questions. Keep the difference in the meeting notes. - [A second brain for AI agents: decide which memories to accept](https://heybrain.io/blog/second-brain-for-ai-agents): A useful memory store needs more than a read path. It needs a way to distinguish a proposed summary from an accepted fact before another agent relies on it. - [Do AI agents need a second brain? Start with what must survive](https://heybrain.io/blog/do-ai-agents-need-a-second-brain): An agent needs durable state when something useful must survive a run. It does not automatically need a new memory service, and restricted data is a separate access question. - [Build a company second brain around decisions people reuse](https://heybrain.io/blog/company-second-brain): The useful record is often a decision and its reason, not another copy of every document. - [AI for Obsidian: check the boundary between your vault and a model](https://heybrain.io/blog/ai-brain-obsidian): A local vault and an AI connection have different access boundaries. Follow the files and the outgoing text before deciding what is appropriate to share. - [What is a company knowledge base—and what does AI change?](https://heybrain.io/blog/company-knowledge-base): A knowledge base earns its place when someone can find an answer they can act on. - [Permission-aware AI search: compare the implementation, not the label](https://heybrain.io/blog/permission-aware-ai-vs-standard-ai): RAG describes how evidence reaches a model. It does not tell you whose evidence the application may retrieve. - [Plan an AI access rollout: from source inventory to owner handoff](https://heybrain.io/blog/set-up-ai-access-governance): Finish a handoff your implementation team can act on, without pretending a planning document configures the system. - [AI on company data: a six-part pre-launch review](https://heybrain.io/blog/ai-on-company-data-checklist): A launch decision needs a defined scope, evidence and an owner for what remains unresolved. - [AI data security: four places company knowledge can escape](https://heybrain.io/blog/ai-data-security-company-knowledge): A restriction on model training does not stop an assistant sending a document to the wrong person. - [AI access governance: four decisions leaders need to own](https://heybrain.io/blog/governing-ai-access-company-knowledge): The tool can enforce a rule. Leadership still needs to choose the rule and who may change it. - [What Is Agent Knowledge? A Plain Guide](https://heybrain.io/blog/what-is-agent-knowledge): An agent can sound informed while reasoning from an expired policy. The knowledge layer decides which facts reach the model. - [What Is Verifiable AI? A Plain-Language Guide](https://heybrain.io/blog/what-is-verifiable-ai): A useful proof names the event, the evidence, and the assumptions. A green verification badge on its own tells a reviewer very little. - [AI agent security: control what it reads and where it goes](https://heybrain.io/blog/ai-agent-security-knowledge-access): A blocked external action does not undo information already supplied to the agent. - [Best Obsidian Alternatives for Teams (2026)](https://heybrain.io/blog/best-obsidian-alternatives-for-teams): Choose the replacement for the work your team actually does: writing together, organizing personal notes, or letting agents retrieve governed knowledge. - [Explainable AI vs Verifiable AI: The Difference](https://heybrain.io/blog/explainable-ai-vs-verifiable-ai): A plausible explanation and a checkable access record answer different questions. Company data needs both the right controls and evidence of their use. - [Choosing an AI brain for agents: compare the job first](https://heybrain.io/blog/best-ai-brain-for-ai-agents): A useful agent brain needs the right context and the authority to retrieve it. Rank candidates against the workload you actually plan to run. - [Choosing an AI brain for developers: repository context or shared memory?](https://heybrain.io/blog/best-ai-brain-for-developers): Keep repository instructions near the code and shared project facts in a source your coding tools can query consistently. - [Agent Knowledge vs Agent Memory](https://heybrain.io/blog/agent-knowledge-vs-agent-memory): Treat approved policy and a remembered conversation differently, even when the same memory engine can store both. - [Agent Knowledge Governance: What Agents Should Know](https://heybrain.io/blog/agent-knowledge-governance): Assign an owner to every agent and make its reading boundary explicit before connecting sensitive sources. - [Verifiable AI for Enterprise Security Review](https://heybrain.io/blog/verifiable-ai-for-enterprise): Bring the evidence package to the security review: a defined boundary, representative requests, and a verification procedure someone else can run. - [Prompt Injection Through Company Documents](https://heybrain.io/blog/prompt-injection-company-documents): A document can supply evidence for a task without gaining the authority to redefine that task. - [Obsidian Alternatives AI Agents Can Use](https://heybrain.io/blog/obsidian-alternatives-for-ai-agents): An agent can query an Obsidian vault through community tooling. The harder requirement is sharing knowledge while preserving different access boundaries. ## Plan your setup - Review the current MCP setup page for connection instructions and requirements. - Check the integration pages and in-app availability before selecting a source. - Evaluate access, revocation, freshness, deletion and data handling for your intended workflow. These are separate requirements; a connection alone does not prove them. ## Integration availability Google Drive: the integration page describes this connector as Coming soon. This Notion update does not verify Google Drive availability; check its current integration page and your workspace. Notion: selected-page import into HeyBrain Library with optional periodic refresh is supported where the connection is offered in the workspace. See https://heybrain.io/integrations/notion and https://heybrain.io/blog/connect-notion-to-ai-agents. This does not establish universal account eligibility, per-reader Notion permission inheritance or source write-back. - [Google Drive availability](https://heybrain.io/integrations/google-drive) - [Notion availability](https://heybrain.io/integrations/notion) ## Who it is for Individuals organizing their knowledge, teams evaluating a shared knowledge workspace, and developers evaluating agent connections. ## Get started Review current plans, then sign up at https://heybrain.io/signup. If you already have a workspace, log in and follow the in-app setup.
