Replace the kitten's random generic tips with a deterministic, LLM-free prose checker that reads the actual document and surfaces one gentle, bilingual note at a time — quoting a slice of her own sentence so the advice is clearly about *this* draft. Rules (all conservative, tuned for a Mandarin-native ESL writer): run-ons, comma splices, unclear antecedents, Oxford comma, a/an, uncountable plurals, capitalize languages/days/months, subject-verb agreement, plural-after-number, double determiner, "there is" + plural, its/it's, than/then, comma-after-transition, doubled words, lowercase "i", sentence capitals, and spacing around punctuation. Each rule is paired with false-positive guards (e.g. "a university", "After dinner, I went home and read", existing Oxford lists) and pinned by a 45-case Vitest suite (npm test). Also: bubbles now linger proportional to how much there is to read (zh+en) and pause-on-hover, so denser advice no longer vanishes mid-read.

🌸 Petal
A self-hosted, privacy-first writing editor with warm bubbly design, auto-save, and
local-LLM grammar/ESL suggestions. See petal-spec.md for the full
design spec and BUILD_PLAN.md for build progress.
Stack
Go + chi backend · SQLite (modernc, pure Go) · React + Vite + Tiptap + Tailwind v4 frontend ·
local vLLM/Ollama for AI suggestions. Single-binary deployment (frontend embedded via go:embed).
Local development
Two processes during development:
# 1. Backend (serves /api on :8080)
go run ./cmd/server
# 2. Frontend dev server (HMR on :5173, proxies /api → :8080)
cd web && npm install && npm run dev
Open http://localhost:5173 while developing.
Production build (single binary)
cd web && npm run build # emits web/dist (embedded by the Go binary)
cd .. && go build -o petal ./cmd/server
./petal # serves UI + API on :8080
Configuration is via environment variables — copy .env.example to .env.
Status
Early build, multi-session. Auth (Authentik), Copyleaks plagiarism, and Docker/Traefik
deployment are deferred — see BUILD_PLAN.md.
