UnboundChat: Private AI (BYOK)

UnboundChat — private AI, on your terms UnboundChat is a privacy-first AI chat app for Android, Windows and Linux. Bring your own API keys, talk to hundreds of models through OpenRouter or directly to OpenAI, Google and others, and keep every conversation on your device unless you decide otherwise. Your data, your rules • Conversations live in an encrypted local database on your device • Optional cloud sync and backups are encrypted on your device before anything leaves it; nobody but you can read them • Timed chat retention, one-tap history wipe, and a separate account deletion that erases everything server-side • No tracking, no ad SDKs, and analytics you can switch off completely Hermes: your own AI agent, in your pocket Run your assistant on your own computer and chat with it from your phone. Hermes relays messages, files, voice notes and tool activity between the two over an end-to-end encrypted channel. Ask it to read a document, check a website or run a task, and get the result as a normal chat message, with notifications when it replies. Your agent, your machine, your data.
