Relay: A Browser with Built-in AI
A Chromium-based AI browser
Relay is a Chromium-based AI browser from Riven. Because it is built on Chromium, the sites, extensions, logins, and workflows you already use keep working. The difference is that an AI sidebar is available on every page you visit.
Built-in AI sidebar
With Relay, an AI sidebar stays available as you browse. You can summarize the page in front of you, ask questions about its content, draft replies, or extract data, without leaving the tab or copy-pasting into a separate chat window. The sidebar connects to Riven's 20+ frontier models, including GPT-5.6, Claude, Gemini, GLM, and Kimi.
Why a browser with built-in AI
A separate chat tab works for standalone questions, but it breaks down when the answer depends on the page you are reading. Relay closes that gap: the AI sees the context you see. That makes it useful for research, support, code review, and any task where the source material lives in the browser.
Free download for macOS, Windows, and Linux
Relay is a free download for macOS, Windows, and Linux. There is no separate AI subscription required to use the browser; the sidebar connects to Riven's pay-as-you-go API at $3 per million tokens, or to your self-hosted Riven deployment.
For enterprise teams
For organizations that need control over their data, Relay pairs with Riven's self-hosted, single-tenant deployments. Self-hosted, single-tenant AI for enterprises that demand control, compliance, and performance. Your infrastructure or ours.
