For those who have ever left a job interview or client call thinking, "I should have said that," Sanity OS has introduced a potential fix. The company launched OTO AI, a desktop application designed to listen to live conversations on platforms like Zoom, Microsoft Teams, and Google Meet. Unlike traditional tools that focus on post-meeting transcripts, OTO provides real-time answers and context while the conversation is still happening.

How It Works

The process is straightforward: users install the app on Windows or Mac and connect their own API key from providers like OpenAI, Anthropic, Google Gemini, or DeepSeek. Once active, OTO monitors the meeting audio and the user's microphone. When it detects a question, it sends the relevant audio snippet to the selected AI model. The response appears directly in the OTO interface, allowing users to glance at facts or structured points without switching windows or typing prompts manually.

Context Is King

A significant limitation of standard chatbots during live calls is the lack of specific background knowledge. OTO addresses this by allowing users to upload documents in formats such as TXT, Markdown, DOCX, and PDF before the meeting begins. This pre-loading ensures the AI can reference project details, company info, or technical specs during the conversation. Furthermore, if someone shares a screen containing charts or code, OTO can utilize multimodal AI capabilities to analyze that visual information and answer questions about it in real time.

Pricing and Philosophy

Sanity OS positions OTO as a counter to the subscription fatigue many developers and professionals face. The tool is sold as a one-time purchase rather than a monthly service. Users pay their AI provider directly for API usage, which can often be covered by a small amount of credit for multiple meetings. The team behind OTO noted that existing solutions were often too expensive or lacked basic controls, such as adjustable text sizes and the ability to distinguish between actual questions and casual chatter.

Key Takeaways

  • OTO AI provides real-time assistance during live meetings, avoiding the awkwardness of typing into a separate chatbot.
  • Users can upload documents (PDF, DOCX, etc.) to give the AI specific context about their projects or the company they are interviewing with.
  • The software supports major AI models via BYO-API keys, including OpenAI, Claude, Gemini, and DeepSeek.
  • Pricing is a one-time purchase for the software, with users paying only for their own AI usage costs.

The Bottom Line

This tool is a practical bridge for anyone who needs a quick memory aid without the friction of manual prompting. It turns AI from a distraction into a silent, helpful copilot for high-stakes conversations.
