About Chervil
Chervil is an agentic browser designed for the frontier-model era, enabling users to delegate web-based tasks to an AI assistant named Sprig. Instead of returning search results, it composes a single, living page tailored to a user’s exact question, complete with inline citations and source freshness indicators. The tool maintains a private, on-device index of a user’s reading history, allowing queries like “what was that laptop review I read last month?” without requiring a new search. It supports setting ongoing goals such as monitoring price drops or tracking updates to specific pages, with changes summarized in a Trust Ledger for review or undoing. Chervil also integrates with RSS, Atom, podcasts, newsletters, blogs, YouTube channels, and subreddits, pulling content in the background and generating briefings on demand. Users can request interactive lessons or quizzes on topics, which are published as shareable links with functional widgets. The browser emphasizes transparency by highlighting where sources disagree on key facts and allows users to correct errors, which are then applied to future compositions.

How does Chervil handle user privacy?

Can Chervil monitor ongoing tasks like price drops or page updates?
Yes, Chervil allows users to set ongoing goals in plain language, such as monitoring price drops or tracking updates to specific pages. Changes are summarized in a Trust Ledger, and Sprig only notifies the user when something actually changes, such as a price adjustment.
Does Chervil integrate with RSS feeds, podcasts, or newsletters?

How does Chervil handle disagreements between sources?
Chervil highlights where sources disagree on key facts by presenting conflicting information alongside the sources that support each position. It avoids fabricating disputes and only flags disagreements when there is a material difference in facts like prices, dates, or measured figures.
Can users correct errors in Chervil’s responses?
Yes, users can correct errors by typing /correct followed by the accurate information. Sprig applies these corrections to future compositions and maintains a dated list of corrections in the Settings, which can be removed individually if needed.
