The web should work for you.
Chervil is the agentic, conversational web browser. Talk to Sprig — and the open web composes itself into a single, living, cited page built for your exact question. Not ten blue links.
Free & open source · Bring your own AI · Runs on your machine
Stop searching. Start asking.
The shift underway is bigger than "AI search." It's the move from answer engines to agentic systems — from an AI that tells you a fact to one that does the work: gathering, organizing, presenting, and maintaining a page made just for you. The destination comes to you, purpose-built, every time.
A full interface for doing things with the web
Composed pages, not links
Ask a question and Sprig composes a single, beautiful, image-rich page — grounded in live web search, with its sources shown.
Deep Dive research
A two-phase pipeline that produces long, fully-cited reports — and vets for disinformation as it goes.
A built-in trust layer
Every page can show its work and one-click verify its own claims against reputable live sources.
Living pages
Tell a page to stay live and Chervil re-grounds it on a schedule, notifying you the moment something changes.
Agentic actions
Sprig can operate real sites for you — safely, with hard gates on logins, payments, and destructive actions.
Bring your own AI
Pluggable providers — Claude, Grok, Gemini, Azure, or local Ollama. Your keys, encrypted on your machine.
Meet Sprig
Every great interface has a face. Chervil's is Sprig — a glowing, leafy guide you actually talk to. Sprig searches, reads, cross-checks, and composes; it shows its work and greets you by name. (Chervil is "French parsley" — the name and the mascot grew from the same plant.)
Open source, and built to be trusted
An agentic browser holds your keys and can act on your behalf — so "trust me" isn't good enough. Chervil is open source: read the code, run it, contribute. Authority doesn't live in the model's reasoning; a deterministic layer governs every action it's allowed to take.
