Brain Chat
Stop searching and start conversing. Use natural language to ask your notes questions and get synthesized, cited answers from your personal knowledge base.
Conversational Retrieval
Query your entire history using natural language to find specific facts or ideas across all your recordings and documents. Instead of typing keywords, ask natural questions like "What did Sarah say about the Q3 budget?" or "Summarize my research on climate policy." Brain Chat understands context across your entire knowledge base, connecting information from multiple notes to provide comprehensive answers without manual searching.
Citations & Sources
Every response includes direct links to source notes, ensuring your AI-generated answers are always verifiable and accurate. Brain Chat cites sources for every claim, allowing you to verify accuracy with clickable references to original notes. The AI is trained to say "I don't know" when information isn't in your knowledge base rather than making things up. You can also provide feedback on answers to improve future responses.
Deep Synthesis
Ask HyNote to compare multiple notes or identify themes to chat with your knowledge base and gain new perspectives. Brain Chat doesn't just find keywords—it understands the semantic connections between your ideas. Ask about a project and get insights from meeting notes, research articles, and brainstorming sessions all in one coherent response, synthesizing information from multiple sources.
Instant Recall
Retrieve buried information from years ago in seconds with the power of semantic search engine technology. Brain Chat indexes your entire knowledge base—transcripts, PDFs, web clips, and typed notes—making everything searchable through natural conversation. You can also limit searches to specific folders or tags for more focused queries. Enterprise users can set permissions for team knowledge bases.
