Chervil Pro

Share what you make.

Chervil is free and open source. Pro adds hosting β€” publish your interactive lessons, quizzes, and pages to a shareable link, with a public profile, per-card analytics, live applets, and your own branding.

Chervil Chat β€” Sprig on your phone

A hosted, chat-only Chervil that runs in any phone's browser at getchervil.com/chat. Sign in and talk to Sprig from anywhere, grounded in live web search, with nothing to install and no API key to bring. Dictate by voice, attach a photo and ask about it, and pick up where you left off β€” the conversation is saved. Tap β€œTo desktop” to beam a chat to the desktop app and continue or compose there. Add it to your home screen and it opens full-screen like a native app β€” and on Android, a home-screen widget puts a chat, a photo question, or voice one tap away. If the managed AI is busy for a moment, Chervil waits and retries rather than dropping your reply. It runs on Chervil's managed AI β€” yours the moment you're Pro, on any device you sign in from.

🌐

Publish lessons, quizzes, pages, blogs & agents

Send any lesson, quiz, interactive page, blog post, agent β€” even a whole Space β€” live to a getchervil.com link that opens on any phone or browser, with a one-tap Share button and rich link previews (your page's hero image shows when the link is pasted anywhere). Lessons keep their hands-on widgets, interactive for every visitor. Free covers 3 of each; Pro is unlimited.

🀝

Pages & agents are remixable

Everything you publish carries an β€œOpen in Chervil” button, so other Chervil users can pull it into their own app and build on it. Your shared work becomes a starting point, not a dead end.

πŸͺ

Reach the Agent store

Submit your best agents and pages to the community Agent store and Share gallery β€” browsable by category, vetted and human-approved, now with community star ratings so strong work stands out. Unlimited published agents on Pro means more you can put in front of everyone.

πŸͺͺ

Your public profile

A getchervil.com/profile/you page with your avatar that gathers everything you've published β€” grouped by Lessons, Quizzes, Blog, and Pages β€” into one shareable library.

πŸ“Š

Per-card analytics

See views, completion rate, and exactly which card learners drop off on β€” a funnel for every lesson, so you know what's landing.

🧩

Live applets on the web

Your hands-on, generative applets keep working for viewers on hosted pages and lessons β€” they call Sprig live, not just inside the app.

🎨

Custom branding

Drop the β€œBuilt with Chervil” badge, set your own cover and social image β€” and, soon, your own domain.

♻️

Hosted living pages

Publish auto-updating pages that re-ground on a schedule and stay current for everyone β€” running in the cloud, not just your machine. In the app, a living page now tells you exactly which figures moved between refreshes, and you can ask it to watch one for you: β€œtell me when the price drops below $1,500.”

Always free

  • βœ“The full Chervil app β€” composed pages, Deep Dive, agents, agent pipelines (incl. orchestrated), Spaces, Living pages
  • βœ“Your Web β€” a private index of your own reading. Search inside the pages you've made and (opt-in) the sites you've read, ask "what was that laptop review I read last month?" and get an answer from your own history with no web search, or have Sprig pull together everything you've read on a subject. It's a file on your machine: never synced, never uploaded, off until you turn it on, private tabs and logins never captured, and deleting really deletes
  • βœ“Your Feeds β€” subscribe to RSS/Atom feeds, podcasts, newsletters, blogs, YouTube channels and subreddits (no API keys), or import your whole list from another reader in one OPML file, folders and all. Chervil pulls them in the background; then ask "summarize the Entertainment folder" or schedule the built-in PulseKeeper agent for a daily briefing of what arrived β€” grouped by theme, linked, from your own sources with no web search. Feeds group into folders, each with its own retention, and a πŸ“‘ subscribes from any page
  • βœ“Instant answers β€” ask something you've already asked and Chervil serves the page you already have, clearly labelled, with a one-click refresh (questions whose answer moves are never cached)
  • βœ“Chat mode with live web search β€” plain conversational answers grounded in current sources, right in the chat; star any answer worth keeping and it lands in Library β†’ Replies, filed under the question that produced it, searchable by its own text, reusable as context for the next question, or openable as a real page
  • βœ“Compare anything β€” ask "iPhone 16 vs Pixel 9" (or two frameworks, two towns) and Sprig builds a sourced, side-by-side comparison table from the live web, with a per-row winner, a bottom-line verdict, and a "best for…" guide
  • βœ“Inline citations & source freshness β€” every claim a composed page draws from the web is cited inline, and the Sources panel shows how recent each source is; refine any page in place with a follow-up right on the page
  • βœ“Share & import pages and agents β€” portable files, or one-click import from the web (browse the store right in the app)
  • βœ“Publish up to 3 agents to your profile + submit to the community Agent store
  • βœ“Sprig on every page β€” ask about the site you're on, translate it in place, read it aloud, snip any region into a question or open it in the built-in image editor (text, erase, crop, upscale, AI edits), compare your open tabs
  • βœ“Publish to your blog β€” send a composed page to WordPress (a real draft via its API, app password kept in the vault), Medium (import-by-URL with a canonical link), or Substack (editor + one-paste); Sprig drafts and fills, you press Publish
  • βœ“A Share this page menu β€” Sprig drafts the post and opens the composer pre-filled: Fedica, AddToAny (100+ services, no account), or any network you've registered; choose which appear and popup-vs-tab in Settings
  • βœ“Your places β€” register your webmail, blog, and socials; "open my email" by keyboard or voice, mailto: links open your webmail, and welcome-screen tiles
  • βœ“A quick chat from anywhere β€” Ctrl+Shift+Space opens the Hey Sprig bar; ask for a page or hold a real inline chat (no tab), then carry it into Chervil
  • βœ“Collections β€” named page sets in the Library that reopen as a named tab group in one command or ground a composed page as Sprig's data source
  • βœ“A complete everyday browser β€” live background tabs (music keeps playing), pinned tabs that pre-warm at launch so mornings are fast, collapsible tab groups, tab search, truly isolated private tabs; import your bookmarks, history, passwords & autofill from Chrome/Edge/Brave/Vivaldi (guided by the first-run Welcome setup); omnibox with history suggestions, per-site zoom memory, spell-check, reader view, an inline PDF viewer, Favorites & folders, multiple windows, downloads, a real print preview (destination, range, copies, layout, paper, margins, scale, colour β€” the sheet redraws as you change them), send-to-phone QR, per-site permissions (camera/mic, location, notifications), ad & tracker blocking, picture-in-picture, a hideable tab bar β€” and set it as your default browser
  • βœ“An encrypted, passphrase-locked vault for logins and payment cards β€” filled on real sites with one click, never auto-submitted, never shown to Sprig (the card security code is never stored)
  • βœ“Pin files to a Space as permanent sources; pick a page style (Balanced / Rich / Minimal)
  • βœ“Sprig's Desk β€” delegate an ongoing goal in plain language ("keep me posted on the Electron 40 release"); Sprig keeps a fresh, cited briefing on it in the background and only pings you when a real figure changed, not when the wording did. Point a goal at a page URL instead and he watches it (price drop, back in stock, docs update). Ask "my briefing" to pull your goals, feeds, and what changed onto one page
  • βœ“The Trust Ledger β€” everything Sprig does on his own, in one plain-language record, newest first, with a one-click undo wherever the action can be reversed
  • βœ“Agentic actions β€” Sprig plans and acts on live sites, every step gated (payments and logins always blocked) and logged to the Trust Ledger; "unsubscribe me from this" drives the page's own opt-out flow, pausing before the irreversible click
  • βœ“Build unlimited lessons locally
  • βœ“β€œHey Sprig” wake word + the quick-ask hotkey
  • βœ“Export to PDF / PowerPoint / Word / Excel / image / GIF β€” and to books: Kindle-ready EPUB or print-ready PDF at real trim sizes with bleed
  • βœ“Export a swipeable lesson as a standalone .html
  • βœ“Bring your own AI β€” Claude, OpenAI, Grok, Gemini, Azure, or local Ollama
