"My thoughts, like spark-riding fireflies, shimmer in the deep silence of your own starry sky."
思想如点点萤火，在属于你自己的寂静星空中闪烁。
Firefly is named after that image: a small, living light moving through a quiet sky. It frames the product as a local-first AI workspace that does not try to dominate your attention, but stays close to your thoughts, catching sparks, shaping context, and illuminating the work already in front of you.
A quiet browser workspace for thoughts that arrive as sparks.
We don’t run a backend that stores your chats or credentials. Session history, model choice, app settings, extension credentials, provider keys / OAuth, and usage totals live only in this browser (IndexedDB via Dexie).
The app still uses the network: Model requests go directly to the providers you configure, unless you explicitly route them through Settings -> Proxy. Optional extensions may call their own network services when enabled. Firefly does not load third-party analytics or event tracking.
| Setting | What it’s for |
|---|---|
| Settings -> Providers | LLM API keys and OAuth credentials for the model providers you use. |
| Settings -> Extensions | Optional AI-callable browser tools and extension-owned credentials/settings. Disabled extensions are not exposed to the model. |
- Browser workspace - Run local-first AI workflows in the browser without a hosted product account.
- Extension packages - The default experience is plain AI chat; installed packages expose a manifest plus lazy runtime/settings entry points and stay disabled until the user enables them.
- Stack - pi-mono with browser-native state and provider access.
- Local first - Agent work runs in a per-tab
DedicatedWorker; durable state stays on the main thread through IndexedDB. - Resilient - Lease ownership, runtime recovery, and interrupted-turn repair all stay inside the browser runtime.
This codebase has been built with substantial AI assistance.
