GoodA complete platform for turning ideas into implementation-ready specs, plans, and insights — all powered by AI.
Describe your app in plain language. The AI asks targeted clarifying questions, then streams a structured spec with architecture, data models, API design, and implementation roadmap.
Built-in chat lets you refine any section mid-stream or after generation. Ask it to expand a feature, switch the architecture, or add edge cases — full spec context is preserved.
Every spec and plan is structured for AI coding agents. Paste into Claude Code, Cursor, or GitHub Copilot as a project context file and start building immediately.
Choose from 10 default spec sections — or add your own. Configure which sections to generate and provide per-section instructions to shape the output precisely.
Pick from a curated list of frontier models via OpenRouter — Claude, Gemini, GPT-4o, and more. Switch models per spec or per refinement pass.
All your specs and plans are saved, searchable, and accessible anytime. Resume, duplicate, or share any document from your library.
Download specs and SEO reports as Markdown, PDF, or Word. Designed to fit any development workflow or documentation system.
Share any spec, plan, or SEO report via a public link. Sensitive shares can require a one-time passcode — useful for handing off to contractors or clients.
Specs and plans auto-save with unsaved-change detection. Edit directly in the rich text editor or chat to iterate — every revision builds on the previous context.
Turn any spec into a full AI-generated PRD — with milestones, user stories, MoSCoW priorities, risk assessment, revenue projections, and success metrics.
Audit any URL across 8 scored categories: Meta Tags, Technical SEO, Content Quality, Structured Data, Performance, Mobile, Links, and Accessibility. 50+ signals analysed per scan.
Your specs, plans, and scans are never used for model training and never shared with third parties. Token usage is displayed transparently for every AI operation.
A growing suite of developer tools designed to bridge the gap between your ideas and AI-powered implementation.
