Turn your daily scribbles into Steam-style patch notes. Local, private, offline-first — no accounts, no servers, data lives only on your machine. It goes online only at the moment you hit “Generate” to call the LLM.

Today · Input & Generate	Result · Patch Notes Card

Left: Today — draft input + one-click generate. Right: Steam-style patch notes card with stackable “More savage / More game-ish” re-rolls, screenshot & copy.

• Today — Write 3–10 lines about your day → Steam-style card. Stackable [More savage] / [More game-ish] re-rolls; auto-saved per day
• History — Grouped by month, newest first. Open any day to view the original card, screenshot / copy / delete
• Reports — Pick a month → auto-aggregate (active days · section counts · 6-stat avg · top Buff/Nerf) → generate Major Release
• Backup — Export / import full JSON for cross-device migration. Same date overwrites, confirmation before import
• Settings — OpenAI-compatible (OpenRouter / DashScope / DeepSeek / Moonshot) Base URL / Key / Model / Temperature 0–2 / Reasoning toggle / Extra params + connection test
• i18n — Full bilingual UI (EN / 中文), default EN, toggle in header or Settings. Preference persisted to localStorage:lpn_lang

Details: one entry per day, version vYY.M.D[.N] auto-increments; draft localStorage:lpn_draft auto-saved; zero animation inside the card for stable screenshots.

Requirements Node.js ≥ 20

# 1. Install (China mirror if needed --registry=https://registry.npmmirror.com)
npm install
# if install scripts are blocked
npm install-scripts approve esbuild workerd && npm rebuild esbuild workerd

# 2. Init local DB (once)
npx wrangler d1 execute DB --local --file schema.sql

# 3. Build + start
npm run build
npm run dev:full   # wrangler dev :8787

Open http://localhost:8787, then go to Settings to configure your API Key.

HMR dev: in another terminal npm run dev (Vite :5173 proxies /api → 8787)

You own the key. Two ways:

• Recommended: Settings → paste Key → Save → Test connection (green). Key is stored in local D1, UI only shows masked sk-or-v1…1042
• Manual: write OPENROUTER_KEY=sk-xxxx in .dev.vars at repo root (already in .gitignore)

Default: OpenRouter · stealth/ox-alpha (free). To switch provider just change Base URL / Model / Key in Settings — no code change needed.

Default EN. Toggle via the EN / 中文 button in the top nav or Settings → Language. Stored in localStorage. Patch content language follows the model’s output (prompts are bilingual-ready).

• Local DB: .wrangler/state/v3/d1/.../db.sqlite (SQLite, survives restarts)
• Migrate to another machine:
  • Option 1: Backup → Export JSON → Import on new machine
  • Option 2: Copy the whole .wrangler/state folder to the same path on the new machine
• Draft: localStorage:lpn_draft (separate from DB)

Never wrangler deploy or expose this project to the public internet:

• No auth — anyone on the internet could burn your API Key
• Key is stored plaintext in local D1, safe only on localhost

package.json has no deploy script on purpose; do not add one in CI. /.dev.vars is in .gitignore — rotate immediately if leaked.

Vite · React 19 · TypeScript 5 · Tailwind 4 · React Bits (FaultyTerminal / SplitText / ClickSpark / ShinyText / SpotlightCard / CountUp) · Cloudflare Worker (local runtime only) · D1 SQLite · html2canvas-pro · Custom i18n (EN/zh persisted)

npm test        # vitest (schema / monthly / text / dates / worker-lib)
npm run build   # tsc --noEmit + vite build

• Slow / failed generation: ox-alpha is a reasoning model, 10–30s is normal. Hit retry on failure. Temperature-related 400s are auto-retried (strip temperature → strip json_mode)
• Port in use: npx wrangler dev --port <other> and update vite.config.ts proxy target
• Use on phone / LAN: Only localhost is intentional. To open to LAN at your own risk: npx wrangler dev --ip 0.0.0.0 (no auth)
• wrangler hangs and won’t exit: Known local quirk — the command already succeeded, just Ctrl+C
