Chervil gives you two ways to work with Sprig. They share the same conversation and the same live-web access — the difference is the output.
Compose mode
This is Chervil's default. You ask for something and Sprig composes a complete, self-contained page to answer it — with real typography, tables, cards, and interactivity where it helps. Composed pages can:
- Search the live web and cite sources when the question needs current data.
- Refine in place — ask for changes and Sprig updates the page rather than starting over.
- Include live applets — small interactive tools Sprig builds into the page.
Every composed page has a Sources panel showing the live pages Sprig used (or noting when it answered from the model's own knowledge — a good cue to run Verify).
Chat mode
Sometimes you just want to talk, not get a whole page back. Switch to chat mode and Sprig replies in plain conversation in the panel — quick questions, brainstorming, follow-ups.
Chat mode is fully web-aware on providers that support search (Claude, Grok, Gemini, OpenAI): Sprig decides on its own when a question needs current information and searches for it, listing the sources it used right under the reply. Ask "what's the weather tomorrow?" or "who won last night?" and you'll get a grounded answer without leaving the conversation. For evergreen questions it just answers directly.
Chat mode also sees the page you're looking at. If Sprig composed a page and you switch to chat, you can ask questions about "this page" and Sprig answers from its contents.
On providers without web search (Azure, Ollama), chat answers from the model's knowledge and will suggest composing a page when a request needs the live web.
Which should I use?
- Compose when you want something to keep, share, or act on — a plan, a comparison, a dashboard, a lesson.
- Chat when you want a fast answer or to think out loud.
You can move between them in the same session — the conversation carries over.
