subtl

A privacy-first semantic search layer that enables natural language querying across local and cloud-based document silos.

Subtl bridges the gap between raw data and actionable intelligence by indexing fragmented knowledge bases (Slack, Notion, and local PDFs) into a unified vector space. It uses local-first processing to ensure sensitive enterprise data never leaves the perimeter while maintaining sub-second retrieval times. By deploying lightweight embeddings and a clean API, Subtl allows teams to query their internal documentation as easily as asking a colleague a question.
