Quickstart

Follow these steps to go from zero to a complete PRD.

Step 1: Create an Account

Sign up at app.thig.ai with your email or Google account.
Password must be at least 8 characters with one uppercase letter, one lowercase letter, and one digit.

Step 2: Complete Onboarding

A quick 4-step wizard personalizes your experience:
  1. Your Profile — Name and job title
  2. Use Case — How you’ll use thig.ai (PM, developer, founder, etc.)
  3. Preferences — PRD style (comprehensive, lean, technical, agile)
  4. Team Setup — Optionally create an organization and invite teammates
You can skip this entirely and go straight to creating PRDs.

Step 3: Pick a Template

Template selection screen
Browse the template marketplace by category:
  • SaaS — Web application PRDs
  • Mobile — iOS/Android app specs
  • eCommerce — Online store features
  • FinTech — Financial products
  • Healthcare — Health/wellness apps
  • AI/ML — AI-powered products
  • And more…
Or start with a blank project for full flexibility.

Step 4: Chat with AI

The AI will guide you through a structured conversation:
  • Answer questions about your product vision, target users, and features
  • Upload existing documents (PDF, DOCX, TXT) for the AI to analyze
  • Use voice input to describe requirements hands-free
  • Watch the requirements panel fill up as the AI extracts key details

Step 5: Generate Your PRD

When the AI has gathered enough context (indicated by the completeness score), click Generate PRD. The document streams in section by section.

Step 6: Review and Export

In the PRD editor:
  • Edit any section with the rich text editor
  • Get AI coaching — a quality score with actionable feedback
  • Export to PDF, DOCX, HTML, Notion, or Google Docs
  • Share with stakeholders via a link (no login required for viewers)
