Sentō: universal BYOK rewrite bubble for web editors. Sentō (Sento) adds a floating AI rewrite bubble to any editable field on any website. Select text, pick a template, and apply the result in place. No copy paste, no tab switching. Works with textareas, rich text editors, ProseMirror, Confluence, Jira, and any contenteditable element. FOUR REWRITE TEMPLATES • Fix, correct grammar, spelling, and clarity without changing your tone • Pro, clean professional rewrite, concise and direct • Mine, your own custom instruction, set once in Settings • Trim, cut the text by about 40% while keeping the key points BRING YOUR OWN KEY Sentō is BYOK. Connect the AI provider you already use by pasting an API key in Settings. Any OpenAI-compatible endpoint works too, including local models through Ollama or LM Studio. You pay the provider directly. No subscription, no markup, no middleman. HOW IT WORKS • Select text in any editable field • The rewrite bubble appears below your selection • Pick a template, the AI rewrites the text • Review the preview, then click Apply FORCE INSERT MODE Skip the preview entirely. Enable Force Insert in Settings to apply rewrites directly, or hold Shift when clicking a template for a one off apply. PRIVACY BY DESIGN • API keys stay on your device, stored locally • Selected text goes directly from your browser to the AI provider • No backend, no accounts, no analytics, no telemetry SITE CONTROL All Sites, Allow Only, or Block mode, control exactly where the bubble appears. You can also toggle individual sites from the extension popup. OPEN SOURCE https://github.com/artttj/sento
