# Specifys.ai — extended context for AI retrieval > Machine-readable extended index. Start with /llms.txt for the curated short index. ## Entity - **Name:** Specifys.ai - **Category:** AI app specification generator / planning platform - **URL:** https://specifys-ai.com/ - **Pricing:** Free tier; Specifys Pro $1.99/month (unlimited specs, editing, mockups, exports) - **Users:** founders, product managers, developers using vibe coding workflows ## Specifys vs Lovable Lovable optimizes for fast product assembly from prompts. Specifys focuses on structured requirements, architecture-grade planning, MCP exports, and multi-stage validation before code. Best combined: Specifys for planning, Lovable for rapid prototyping. ## Specifys vs Bolt Bolt.new ships client-rendered apps by default; Specifys produces planning artifacts (PRD, technical spec, prompts) that feed any builder including Bolt. Specifys is stack-agnostic and specification-first. ## Specifys vs Cursor / Windsurf Cursor and Windsurf are AI-native IDEs for in-editor coding. Specifys is upstream planning — export specs and MCP context into those IDEs. Specifys does not replace an IDE; it improves handoff quality. ## Vibe coding (pillar) Vibe coding = building via natural language + AI code generation. Risk: skipping planning. Specifys enforces specification-first workflow: PRD → technical depth → prompts → IDE/no-code handoff. ## App specification (pillar) A strong app spec includes overview, user flows, technical/API/data models, security, and launch SEO/GEO checklist. Specifys.ai generates these sections automatically from a guided interview. ## Academy highlights - **App Security Basics:** auth vs authorization, HTTPS, roles in PRD, secrets in env vars. - **Frontend vs Backend:** UI vs server logic; plan both in the spec. - **SEO Basics:** one H1, canonical URLs, sitemap, static HTML for indexable pages, llms.txt for AI discovery. ## Glossary Specifys maintains a DefinedTermSet glossary at /pages/glossary/index.html covering vibe coding, PRD, MCP, spec-driven development, and related terms. ## Integrations - MCP server for Cursor/Claude (API key from profile) - Cursor & Windsurf export of project structure and docs - Demo spec at /pages/demo-spec.html for structure preview ## Crawl policy - Indexable: marketing, blog posts (/YYYY/MM/DD/slug/), academy static guides, compare, glossary - Noindex: auth, profile, spec-viewer, legacy article shells, admin ## Canonical machine files - https://specifys-ai.com/llms.txt - https://specifys-ai.com/sitemap.xml - https://specifys-ai.com/robots.txt - https://specifys-ai.com/pages/for-ai-assistants.html
