JavaScript Library
Summary
Surmiser is a UI-agnostic JavaScript autocomplete primitive that adds Smart Compose-style predictive text to any web input. It runs a local, privacy-first prediction engine by default, supports React, vanilla HTML, and major UI libraries, and offers a provider architecture for plugging in remote APIs or LLMs.
Highlights
- Local-first prediction engine with a default phrase corpus; no data leaves the client by default
- UI agnostic: drop-in React component, React hook, or vanilla JS attach function for any input element
- Provider architecture allows swapping the local engine for remote APIs, LLMs, or custom logic
- Mobile gestures (swipe right to accept, double space to dismiss) and keyboard shortcuts (Tab, Arrow Right)
- Custom corpora supported via simple string arrays for domain-specific suggestions
