What you pay for
- On your computer: nothing per use. You pay in disk space, memory and electricity, at lower quality.
- publik API: publik’s published price for each use, in dollars, from your publik balance. It is above the model’s cost; the difference runs publik and pays the app’s builder.
- Your own key: the provider’s price, billed to an account you keep with the provider.

README
Open in GitHubPlantGPT
Pixel-parity desktop clone of ecogpt.com ("Regenerative AI") built with Tauri v2 + React + Vite — except it's 100% local and free: inference runs through Ollama on your own machine. No accounts, no keys, no cloud, no ads, no analytics, no cost.
What's cloned (and what's upgraded)
| Area | Parity | Notes |
|---|---|---|
| Sidebar, empty state, input pill, tools menu | ✅ pixel-matched | tokens extracted from the real site (UI-SPEC.md) |
| Chat thread (user bubbles / plain assistant text, action row) | ✅ | |
| Impact drawer (isometric field, trees/CO2/H2O/light, badges, About/Friends/Rankings) | ✅ | stats computed locally, 1 tree per 100 messages |
| Search chats modal (⌘K), chat history, rename/delete | ✅ | |
| Projects | ✅ upgraded | real site gates them behind login; here they work locally |
| Markdown rendering | ⬆️ better than the original | real headings, numbered lists, green blockquotes, code blocks with language header + copy + syntax highlighting, KaTeX math, rounded tables |
| Web search | ⬆️ free + local | DuckDuckGo HTML results fetched natively and fed as context |
| Study mode | ⬆️ unlocked | tutoring system prompt (login-gated upstream) |
| Login/ads/analytics | ❌ intentionally dropped | replaced by a Settings modal (model, theme, username) |
