Everything you need to get going with Chervil — the agentic browser where Sprig composes pages, runs agents, and takes real action for you. New here? Download for Windows and start with Getting Started.
Getting Started
What Chervil is, how to install it, and how to ask Sprig for your first page.
Connect Claude, Grok, Gemini, OpenAI, Azure, or a local Ollama model — and which ones can search the web.
Switch from Chrome, Edge, Brave, or Vivaldi without leaving anything behind — import your bookmarks, browsing history, saved passwords, and address autofill into Chervil.
Using Chervil
Use Sprig on the live website you're viewing — ask about the page, translate it in place, have it read aloud, snip any part of the screen into a question, and compare your open tabs.
The ordinary browser features Chervil has so it can be your only browser — live background tabs, tab groups, tab search, Collections, Your places, importing from Chrome/Edge, Favorites & folders, saved chat replies, zoom, downloads, a real print preview, reader view, truly private tabs, multiple windows, ad blocking, spell-check, and setting Chervil as your default browser.
The two ways to talk to Sprig — build a page, or just have a conversation — how web search works in each, and how to keep a chat answer you want back later.
Get a long, cited research report — or fact-check any page against the live web.
Sprig doesn't just answer — it opens maps, places calls, reads your PC, and browses real sites.
Delegate an ongoing goal in plain language and Sprig keeps at it in the background — standing intents, page watches, the Trust Ledger, schedules, and your daily briefing, all in one place.
Collect pages into a research Space so Sprig can synthesize across everything you've gathered.
Give Sprig a persona and instructions — or a whole team of specialists that work together.
Talk to Chervil hands-free with the on-device wake word.
Chervil's encrypted, passphrase-locked vault for saved logins and payment cards — how it stores them, how the 🔑 and 💳 fill buttons work, and the security guarantees (never auto-submitted, never shown to Sprig, CVC never stored).
Subscribe to the sources you follow, import your whole OPML, and have Sprig brief you on what arrived — grouped, ranked, and linked, from your own sources.
A hosted, chat-only Chervil that runs in any mobile browser — sign in and talk to Sprig from anywhere.
Chervil can keep a private, local index of the pages you read — so you can ask what you read last month, pull together everything you've read on a subject, and have Sprig answer from your own reading. Local, off by default, and yours to delete.
