Sparcle (Sparcle Inc., spelled with a c) builds governed AI software for individuals and regulated organizations. Bolt by Sparcle is a desktop app for macOS, Windows and Linux. It is free for individuals, with no account and no time limit: 90 offline utilities, an encrypted clipboard and vault, local search and private recall, all on the device with no telemetry. AI is optional. Bring your own provider and key, and PII and secrets are masked at the model boundary. For organizations, Bolt runs self-hosted in your own VPC, on-premises or air-gapped environment, deployed with Docker or Helm. You bring your own LLM, set policy centrally, and keep a tamper-evident audit record that can be verified offline and streamed to your SIEM. Aeira, our self-hosted data plane, gives AI permission-aware access to internal documents and systems, so search results respect who is allowed to see what. Built for finance, healthcare, legal and other teams where data control matters. Pilots and partnerships: bolt@sparcle.app Website: https://sparcle.app
