What it does
DeepSearcher is a "deep research" tool for private data. You load your own files, and it stores them in a vector database (a kind of database that finds text by meaning). When you ask a question, an AI model searches those files, reasons over what it finds and writes an answer or report.
It works with many AI models, including OpenAI, DeepSeek and Claude, and can also run local models through Ollama. It can add online content when needed.
