ASK · AI SEARCH
ASK A QUESTION.
GET THE ANSWER.
Brain reads your graph and tells you what you already decided, who said it, and where it lives. Citations on every answer. Zero archaeology.
GRAPH-AWARE RETRIEVAL
Semantic search across entities, relations, and concepts. The structure carries meaning.
EVERY ANSWER CITED
See the underlying notes that produced the answer. No hallucinations passed off as memory.
AGENT-READY
The same retrieval surface your AI agents use. One source of truth for humans and machines.

[ STATUS ]
On 2026-04-22 you settled on a phased rollout: phase 1 with channels A and B, phase 2 in week 4 once compliance review clears, phase 3 held to next quarter. Three sources cited.
CAPTURE LAYER
EVERY TOOL.
ONE INBOX.
Knowledge already lives in Slack threads, email, calendars, voice memos. Brain pulls it in, deduplicates, and routes each item to the right entity. You stop filing.
SLACK + EMAIL + DRIVE + VOICE
Six native sources at beta. More on the roadmap (Notion, GitHub, Linear, webhooks).
AUTO-ROUTED TO ENTITIES
Every item lands in the right project or person automatically. No manual filing.
DEDUPLICATED
Same idea forwarded twice does not become two notes. The graph collapses noise.

HONEST COMPARISON
BRAIN VS THE WIKIS.
Notion, Slite, and Obsidian are good products. They are also built for pages, not graphs, and most of them route your data through US clouds by default. Here is the honest read.
| CAPABILITY | BRAIN | NOTION | SLITE | OBSIDIAN |
|---|---|---|---|---|
| Storage model | Knowledge graph (entities + relations) | Pages + databases | Documents + folders | Markdown + backlinks |
| AI search | Native, graph-aware retrieval | Notion AI add-on, doc-level | Ask, doc-level | Third-party plugins |
| Default data region | EU only · Frankfurt | US default · EU on Enterprise | US default | Your device |
| GDPR Art. 28 DPA | Included on every paid tier | Enterprise tier only | Available on request | Not applicable |
| EU AI Act audit log | Hash-chained, ships at launch | No native support | No native support | No |
| Markdown export | Lossless · whole graph | Lossy · databases drop out | Limited fidelity | Native (files are markdown) |
| Auto-capture from Slack + email | Native, auto-routed to entities | Via integrations | Slack connector | Not supported |
| Solo + team in one product | Yes · same graph, shared or private | Yes | Team-only | Solo-only · sync is paid add-on |

FAQ
COMMON QUESTIONS.
Templated wikis store pages. Pages pile, they do not connect. Brain models your knowledge as a graph of entities, relations, and concepts. AI retrieval reads the same graph humans do. Notion and Slite were built before AI-native search mattered. Brain is built around it.
