FAQ

Questions accounting and tax firms ask

  • How did we treat R&D credits for Aster Collective last year?

    The prior-year working paper records the treatment and supporting research. The review note identifies the responsible partner. 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.

  • What's our year-end stock count procedure?

    The firm procedure lists stock-count planning and review responsibilities. The checklist links the current instructions. Connect the relevant Drive folder or Notion pages, or upload documents, then follow citations to their original passages from the AI tools your colleagues already use.

  • 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.
