Sonoyo

Shows a GPT-5.6 Luna research panel in the right-hand column of Google search results, built from its own extra web searches.

Sonoyo takes the work of opening result after result to check what is true, and hands it to a model. When you search on Google, a panel appears in the right-hand column and GPT-5.6 Luna runs its own web searches right there. It does not paraphrase the results you can already see: it searches the topic itself and cross-checks what it finds, so background and caveats become visible. Every claim carries an inline citation, and the pages the model consulted are listed under each card. No source-less summary that sounds plausible but cannot be verified. ■ Features ・Research on the query itself Sonoyo searches the web for the search phrase itself and reports key points, detail, caveats, and what to search next — starting from what you were trying to find out, not from the links already on the page. ・Inline citations Claims link to the page the model actually read, and every consulted page appears as a chip under the card. ・Live progress, stoppable You see "Searching: …", "Reading results…", and "Writing the summary…" as they happen, and the text streams in as it is written. Press ✕ in the header to stop — billing stops there too. ・The same search is not billed twice An identical query with identical settings is served from cache for 24 hours by default (adjustable from off to 7 days), so reopening a search page does not generate again. ・Usage in plain sight Runs, extra searches, and input/output tokens for the current month are shown in the popup. ・Follows Google's appearance setting By default the panel matches the light / dark setting of Google Search itself, so it stays consistent even when that setting differs from your OS or browser theme. You can also pin it to light or dark. ・Readability controls Panel width (300–560px) and text size (11–18px) are configurable; text size scales every label in the panel proportionally. IBM Plex Sans JP ships with the extension, so the panel looks the same on every machine. ・Built to survive layout changes The panel falls back through "Google's right column → its own column → floating at the right edge", and placement does not depend on specific class names, so a Google redesign does not make it vanish. ■ What you need Sonoyo runs on your own OpenAI API key (an account with access to GPT-5.6 Luna and the hosted web_search tool). Issuing the key and paying for usage are between you and OpenAI; the publisher of this extension does not cover API costs. ■ How to use 1. Install from the Chrome Web Store 2. Open the 🌙 toolbar icon and paste your OpenAI API key (it saves when the field loses focus) 3. Search on Google as usual — the research appears in the right-hand column 4. Turn automatic runs off if you prefer to press "Research" yourself 5. Adjust reasoning effort, cache duration, appearance, and text size from the popup ■ Notes ・Works on Google's regular search tab. Image, video, shopping, and book tabs are not supported. ・Output is an AI summary and can be wrong. Check the cited sources before relying on it.
