Chervil is an agentic browser for Windows. Instead of hunting through search results and tabs, you tell Sprig — Chervil's leafy guide — what you want, and Sprig composes a complete, purpose-built page to answer it: a comparison, a plan, a dashboard, a lesson, a live mini-app. When a request needs the real web, Sprig searches it; when it needs to do something, Sprig takes action.
Install
- Download the latest installer from the Releases page (
Chervil-Setup-X.Y.Z.exe). - Run it. Chervil installs for the current user — no admin rights needed.
- Launch Chervil from the Start menu.
Windows may show a SmartScreen prompt on first run because the installer isn't yet signed by a widely-recognized certificate. Choose More info → Run anyway to continue.
Add a provider
Sprig is powered by an AI model, so the first thing to do is connect one under Settings → Provider. Chervil works with Claude, Grok, Gemini, OpenAI, Azure, and local models via Ollama. See Providers & API keys for the details and which ones can search the live web.
Your first page
Type what you want into the prompt and press Enter. Try:
- "Compare the top 3 note-taking apps for me in a table."
- "Plan a 3-day trip to Lisbon with a map for each day."
- "Teach me how a transformer works, with a quiz at the end."
Sprig composes a page in response. From there you can keep the conversation going — ask for changes ("make it darker", "add a budget column") and Sprig refines the page in place.
Where to go next
- Compose vs. Chat — the two ways to talk to Sprig.
- Deep Dive & Verify — long researched reports and fact-checks.
- Real-world actions — maps, calls, and live applets.
