Whichi Studio
Spec-Driven AI Development

The intelligent spec editor that transforms vague ideas into crystal-clear specifications. Built-in validation, templates, and a 4-phase workflow that scales from side projects to enterprise apps.

What Makes Whichi Studio Different

Precision Over Guesswork

No more vague prompts that force AI to guess. Whichi Studio guides you to create detailed specs that capture your exact intent.

Built-in Validation

Every phase has checkpoints. Review and validate before moving forward. Catch issues early, not after 1000 lines of wrong code.

Git-Powered History

Every change is versioned. Undo mistakes, compare versions, and time-travel through your project with one click.

The 4-Phase Workflow

Whichi Studio breaks AI development into four clear phases. Each phase validates before moving forwardβ€”no surprises, no rewrites.

Phase 1

Specify

Define the What & Why

Start by describing user journeys, key experiences, and success criteria. Whichi Studio helps you structure your vision into a comprehensive specification document.

Template library for common app types
AI-assisted spec generation
Markdown export for documentation
Validation checkpoints
Phase 2

Plan

Create Technical Blueprint

Provide your tech stack, architecture preferences, and constraints. Whichi Studio generates a detailed technical plan that respects your standards.

Stack-aware planning (React, Vue, etc.)
Architecture patterns (MVC, microservices)
Database schema design
API endpoint definitions
Phase 3

Tasks

Break Into Manageable Chunks

Whichi Studio transforms your spec and plan into small, reviewable tasks. Each task is independently testable and focused.

Automatic task breakdown
Dependency tracking
Parallel vs sequential identification
Time estimates per task
Phase 4

Implement

Build & Validate

AI tackles tasks one by one. You review focused changes instead of overwhelming code dumps. Live preview shows results instantly.

Task-by-task execution
Live preview server
Incremental testing
Git commit per task
