TerraHarness gives you a durable personal AI agent — claim it once, choose your model, and pick up where you left off from any device. No setup burden, no credential plumbing.
Sign in with your email one-time code, claim your isolated agent, pick a model from OpenRouter, and start a conversation — streaming responses appear as they're generated.
Your conversation history persists between sessions. Return from a different device and the thread is exactly where you left it.
Each user gets an isolated agent with its own durable conversation history. Return later or switch devices without losing the thread.
Choose from models available through OpenRouter. All model traffic is routed through a centralized gateway for unified delivery and visibility.
Responses appear as they are generated, creating a fast and natural chat experience on desktop and mobile.
See request and token usage alongside an audit trail of important actions. Correlation IDs help trace individual requests when troubleshooting.
Reset the conversation, disconnect or reconnect model access, and suspend or reactivate the agent directly from the control center.
Identity is verified at every request before any AI call is processed. Provider credentials stay server-side — they never reach the browser.
TerraHarness is built from the ground up to keep your agent under your control — verified access at every request, isolated state, and credentials that never touch the browser.
TerraHarness is rolling out to a small group of technical teams and independent operators. Request access and get a durable personal AI agent under your control from day one.
