VibeBlocks

VibeBlocks is a web-based AI specification generator for developers, founders, product managers, and teams who want to turn vague app ideas into structured, spec-driven blueprints they can hand off to AI coding tools.

Key capabilities include:

• Full technical blueprints from one prompt, covering idea breakdown, requirements, design details, and implementation tasks in a nested structure.
• Multi-modal input, letting users type an idea, upload a sketch, or use voice to capture requirements on the go.
• Editable and iterative specs, with the ability to re-run sections and reuse outputs across iterations.
• Exports for AI coding workflows, including copy-paste and export to Markdown or PDF for tools such as Lovable, Cursor, Bolt.new, v0, and Replit, plus model switching (GPT-4o, Claude, Grok 4, Groq).

Pricing: Freemium ($0 Free plan with 100 credits; $9.99/month Vibe; $29.99/month Code).

What makes it notable is its focus on producing spec-first, tool-ready outputs (requirements plus tasks and design structure) to reduce wasted AI credits and rework caused by under-specified prompts in “vibe coding” workflows.
