Open WebUI Assistant

AI-powered text tools using your local Open WebUI instance

Open WebUI Assistant – Local AI + the Only OIDC/SSO Extension AI writing tools powered by your own Open WebUI instance. Right-click to rewrite, fix, summarize, translate, and chat — the only extension with OIDC/SSO built in. ----------------------------- Transform your browsing experience with AI-powered text tools that work seamlessly across the web. Open WebUI Assistant connects your self-hosted Open WebUI instance directly to your browser — giving you instant access to your own language models wherever you write, with your data never leaving your control. Whether you're running Open WebUI at home or rolling it out across an organization, this extension meets you where you are. And for teams that need it: this is currently the only Chrome extension that brings OIDC/SSO login to Open WebUI, letting employees sign in with the identity provider your organization already uses — Okta, Azure AD, Keycloak, Auth0, Authentik, and more — instead of a separate username and password. What it does Right-click any selected text for instant AI actions: ✏️ Rewrite — Improve clarity and flow, replaced directly on the page ✓ Fix Grammar — Silently corrects errors in place 🔍 Check Grammar — Detailed explanations in the side panel 📈 Expand — Add ~25% more detail while keeping your tone 📉 Shorten — Condense to key points, edited in place 📄 Summarize — Concise summary in the side panel 💬 Chat — Conversation about the selected text with full page context 🌐 Translate — English and Spanish free; 10 more languages with Pro 🔊 Speak Aloud — Read any selection aloud instantly Right-click with no text selected: 📖 Explain This Page — Full AI summary and analysis of any webpage Also included: memory of previous interactions, and a direct Open WebUI side panel for side-by-side chat. Built for regulated and security-conscious teams — and everyone else Because everything runs through your own Open WebUI instance, nothing you write is sent to a third-party AI service. That makes this a fit for organizations that can't use public AI tools at all — healthcare, legal, education, government, and any workplace with strict data-handling requirements. OIDC/SSO login means IT can manage access the same way they manage every other internal tool: through the identity provider they already run. Works everywhere you write Gmail, Outlook, Google Docs, Google Sheets, Google Slides, and any website or text field in Chrome. Free features include: All core writing tools (rewrite, expand, shorten, fix grammar, summarize, chat), browser text-to-speech, saved prompt library, pinned items board, export chat history, 3-day interaction memory log, and translate to English and Spanish. Pro and Enterprise licenses (including OIDC/SSO) are purchased as a one-time fee per seat.
