FAQ

Questions teams ask

  • What did I note about the Lisbon client?

    Your Lisbon project notes record the agreed scope and next review date. The saved brief contains the client's priorities. Ask follow-ups in the same conversation and open each citation to check the surrounding detail, then share the source with colleagues who can access the same collection.

  • Can I compare pricing research saved in Notion and PDFs?

    Connect your Notion notes and upload the PDF report, then ask how the pricing approaches compare. HeyBrain brings back the relevant notes and supporting figures with their sources. Open the citations to read the original details, and ask follow-up questions from the same collection as you develop your comparison.

  • Which sources and AI tools can we use?

    Connect Google Drive, Notion and document uploads; Claude, Cursor and Codex ask your company knowledge through HeyBrain MCP. Keep decisions and references available where your team works. HeyBrain supplies knowledge; agents use their own tools for actions requested by the user.

  • How does HeyBrain keep private knowledge private?

    People and agents receive answers from sources they can open. Workspace rules restrict the audience; each agent has its own key and scope. Administrators review requesters, times and source references in activity records alongside workspace membership and source access rules.

  • How do we get the team started?

    Connect your team’s current brief, decision notes and working guide, invite the people who need them and ask a familiar question. Open its source citations before expanding the collection. Align workspace membership and individual agent scopes with each team’s responsibilities.

  • How does HeyBrain reduce AI token cost?

    HeyBrain sends only the context a task needs instead of repeatedly passing whole documents to your AI tool. Use the context calculator to compare the amount you send and your input price. Your team shares the same connected knowledge across tools, so every new conversation can start with the relevant passages and their sources.
