LLMSymphony

One Secure Chat. Multiple AI Models. Your API Key.

Free Download for Windows

Empowering professionals and enthusiasts who value privacy and control - to have conversations with frontier AI models like ChatGPT, DeepSeek, Gemini and Claude while minimising exposure to data breach events and information harvesting practices.

Benefits

Incognito Mode (by default)

Chats are stored in-memory and disappear when you close the app, unless you save them to disk.

Encryption at Rest (on your PC)

Your saved chats and API keys are encrypted and tied to your PC's unique hardware and software fingerprint, protecting your confidentiality in the event of malware, data exfiltration or use of data recovery tools against your storage device.

Better Privacy Protection (on the AI Model Provider)

By using "developer" API keys with your AI model hosting provider, you're protected by stronger privacy policies with greater control of chat retention and data sharing settings. If the AI Hosting provider suffers a data breach your chats are not exposed or only minimally exposed. You're in control.

No middle man (by design)

All chats are directly between you and the AI hosting provider. We do not store or have access to your encryption keys or chats.
