The Chervil blog

Building the agentic, conversational web browser in public.

Floating around him are floppy-disk save icons, a printer feeding a sheet of paper, loose pages, green checkmarks, and blue speech bubbles; sailboats and calm water fill the background.

Chervil 0.28.0: Keep the good answers

Chat could give you a brilliant answer and then lose it the moment you closed the tab. Now a star keeps it. Plus: Chervil grew its own print preview, because the one Windows was showing said it didn't have one — and a bug I found on the way that could break printing until you restarted the app.

Chervil 0.27.0: Sprig on your home screen

Chervil Chat has lived in your pocket since 0.22 — but you still had to go find it. This release puts Sprig on your Android home screen: a one-tap widget that drops you straight into a chat, a photo question, or voice. Plus a fix for the most confusing way publishing could fail.

Chervil 0.26.0: Sprig's Desk

Until now Chervil answered when you asked. This release lets you delegate — hand Sprig an ongoing goal in plain language and he keeps at it in the background, tells you only when something actually changed, and shows you everything he did while you were away. It's the browser that keeps working when you close the laptop.

Chervil 0.25.0: show your work

An AI that answers in one confident voice is hiding something — the places its sources didn't agree. This release is about Chervil showing you the seams: where the web contradicts itself, which claims it actually checked, and what came from your own reading. And it starts remembering the things you tell it it got wrong.

Chervil 0.24.0: the tune-up

No new vertical this time. Chervil used to freeze for about half a second at a time while you worked, chat sat silent until the whole answer was ready, and the Trash kept everything you ever deleted, forever. All three are fixed — and chat now starts answering in under half a second.

Chervil 0.23.0: beam your chat from phone to desk

Chervil Chat grew up. Talk to it, show it a photo, and it remembers where you left off. And when a question you started on your phone turns into real work, tap “To desktop” — the whole conversation beams over to the desktop app, ready to continue or compose into a page. Plus: managed AI on Grok is working again.

Chervil 0.22.0: Sprig in your pocket

Chervil is a desktop browser — that's the whole point. But you're not always at your desk. Chervil Chat is a new, hosted, chat-only Chervil that runs in any phone's browser: sign in and Sprig is a tap away on your home screen, grounded in live web search, with nothing to install and no API key to bring. Plus the desktop quick-chat finally stays open while it answers you.

Chervil 0.21.0: your feeds, briefed

You already have a feed reader you like. Chervil 0.21.0 isn't trying to be a better one — it's the browser that reads your feeds for you. Bring your whole OPML over, folders and all, then just ask: "summarize the Entertainment folder." Sprig briefs you on what arrived, grouped and linked, from your own sources with no web search. Plus the Library is a real page now.

Chervil 0.20.0: your browser finally remembers what you read

Every browser keeps a list of where you've been and throws away what was there. Chervil 0.20.0 keeps a private index of your own reading — on your machine — so you can ask "what was that laptop review I read last month?" and get the answer with no search at all. Plus dossiers that pull together everything you've read on a subject, repeat questions answered instantly, and a top bar that finally looks like a browser's.

Chervil 0.19.1: compare anything, cite everything, watch the web

Chervil takes on the search engine head-on. Ask it to compare two things and it builds a sourced, side-by-side table with a verdict. Every composed page now cites its sources inline and shows how fresh they are. And Chervil can watch a page and ping you when something changes — a price drops, an item's back in stock, the docs update. Plus refine any page in place with a follow-up, resizable sidebar and tab bars, and a toolbar that never hides its buttons.

Chervil 0.17.0: fast mornings

The release about the friction you feel every single morning. Pinned tabs now warm up in the background the moment Chervil launches, so the first click on each one shows a loaded page — not a spinner. Tab groups grew a visible fold arrow, and opening a Collection now drops its pages into a tab group named after it.

Chervil 0.16.0: your places, your collections — and a book press

Chervil learns where you live on the web — say "open my email," let mailto links open your webmail, and have Sprig draft posts to your networks when you publish. Gather pages into Collections that Sprig can compose from. And the big one: turn any lesson or page into a real book — a Kindle-ready EPUB or a print-ready PDF, with a built-in image editor that upscales for print.

After making it easy to switch to Chervil, 0.14.0 is about the everyday details that decide whether you stay — sites that ask for your camera the way a real browser does, PDFs that just open, a wake word that won't compose a page from the TV, and a password vault that finally feels like a manager.

The hardest part of trying a new browser is everything you'd leave behind. So 0.13.0 imports it — your bookmarks, history, saved passwords, and address autofill from Chrome, Edge, Brave, and Vivaldi. Plus a reorganized Library (Favorites for websites, Saved Pages for what you compose) and a fix so deleted things stay deleted across your synced machines.
