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 Knowledge Retrieval
Chat with your personal AI to surface insights from your notes without manual searching. 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.

Context-Aware Responses
Receive answers that synthesize information from multiple notes, understanding relationships between concepts. 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.

Source Citation & Verification
Every answer includes clickable references to original notes, ensuring transparency and easy fact-checking. Brain Chat cites sources for every claim, allowing you to verify accuracy. 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.

Mobile Voice Queries
Use voice input to ask questions hands-free on iOS and Android apps. The mobile experience is optimized for quick queries on the go. Ask questions while commuting, walking, or multitasking—Brain Chat responds with spoken answers or text, your choice.
