Nimble

Ask a question. Get one sentence back.

Math, units and graphs answer on the device. Everything else goes to two open models at once, and DuckDuckGo and Wikipedia catch what they miss. No API keys, no accounts, no telemetry.

Get it

iPhone and Mac	App Store
Mac, direct	Latest release, signed and notarized. ⌥Space summons it
Windows, Android	.msi and .apk on the same release
Web	nimble.heyitsmejosh.com/app, works offline once loaded
Terminal	swift build && ./.build/debug/nimble-tui "your question"

How it answers

1. Units, math and graphs: evaluated on the device. 5 miles to km, 15% of 240, plot sin(x).
2. Dictionary, weather, local time and currency: pattern-gated live sources.
3. Everything else: Gemma and Qwen3 run side by side on Cloudflare Workers AI through worker/worker.js. Agree and you get it; disagree and the two are folded into one sentence. Numbers are cross-checked against DuckDuckGo. Both give up and Wikipedia answers.

Agents get the same engine at https://nimble.heyitsmejosh.com/api/answer?q=5+miles+to+km and over MCP at https://nimble.heyitsmejosh.com/mcp. Tools: answer, convert, math, graph.

Every answer names its source. Light and dark follow the system. 8 accent themes.

What else it does

Weather, currency, local time and word origins come back as cards. Recent questions sit under the field on every surface and never leave the device. Follow-ups work: ask "and in celsius?" and the last three turns come along. Tap the mic and ask out loud. Share any answer as a yellow card. A home screen widget keeps your last answer on iPhone; the Mac answers straight from the menu bar. Agents get the same engine over REST at /api and MCP at /mcp. Five languages: English, French, Spanish, Chinese, Punjabi.

Development

xcodegen generate && open Nimble.xcodeproj   # macOS + iOS
node --test 'test/*.test.*js'               # web engine
cd worker && npx wrangler deploy             # answer proxy
scripts/release-macos.sh                     # signed, notarized Mac zip

The landing page is the web app: docs/index.html + docs/app.html + docs/engine.js, deployed to Cloudflare Pages on push. The app icon is Nimble.icon, an Icon Composer bundle.

Open work is in roadmap.md. Design notes in the whitepaper.
