Built for Enterprise Developers

On-Device AES-GCM Keyring

API credentials are encrypted client-side using 256-bit AES keys derived from your Master Password via PBKDF2. Decrypted keys exist only in transient execution scopes.

Context-Preserved Switch

Swap models dynamically between OpenAI, Anthropic, Gemini, and local Ollama mid-conversation. Context structures are normalized on-the-fly to sustain history.

DNR Initiator Lock protection

Local CORS-bypass network headers are restricted via declarativeNetRequest rules to match ONLY requests initiated by the unique extension ID origin.
