1. Introduction and Overview

VibeGen is an AI-powered platform that takes indie hackers from initial idea to implementation-ready task list in minutes. It combines multiple AI models, real-time web research, and developer-native tooling into a single workflow: generate ideas tailored to your target market, score them across five dimensions, produce PRDs and task breakdowns, validate demand through simulated customer interviews, and export everything directly to GitHub Issues, Linear, Jira, or Notion.

Who It Is For

• Indie hackers looking for their next project with a clear build path
• Solopreneurs who need market validation before investing time
• Startup founders who want to move from concept to execution plan quickly
• Side-project builders exploring weekend or multi-week project ideas
• Technical creators who prefer developer-native workflows over generic business tools

The Problem

Most AI idea generators produce US-centric suggestions without regard for regional markets, stop at the idea stage without offering implementation guidance, and scatter their output across disconnected tools. There is no end-to-end platform that generates region-specific ideas, rates them on multiple dimensions, produces PRDs with developer-ready tasks, validates demand, and exports to the tools developers actually use. VibeGen fills that gap.

2. Quick Start Guide

Registration

VibeGen supports three registration methods:

• Email and password -- create an account with your email address
• Google OAuth -- sign in with your Google account
• GitHub OAuth -- sign in with your GitHub account

The registration page with email and social sign-in options.

Onboarding (3 Steps)

After registration, a brief onboarding flow personalizes your experience:

1. Skill level -- Select Beginner, Intermediate, or Advanced. This adjusts the complexity of generated ideas and the level of technical detail in outputs.
2. Preferred categories -- Choose from 12 categories (SaaS, Mobile App, Chrome Extension, CLI Tool, API/Backend, AI/ML, Dev Tool, Marketplace, Social Platform, Productivity, E-commerce, Game).
3. Preferred industries -- Choose from 12 industries (Technology, Finance/FinTech, Health & Wellness, Education/EdTech, E-commerce/Retail, Marketing/AdTech, Creator Economy, Real Estate, Travel & Hospitality, Food & Beverage, Entertainment, Sustainability).

These preferences persist across sessions and influence idea generation, swipe recommendations, and weekly digest content. You can change them at any time in Settings.

Generating Your First Idea

1. Navigate to the Generate page from the dashboard.
2. Walk through the 6-step wizard (detailed in Section 3).
3. Answer optional follow-up questions to refine your criteria.
4. Receive 3-5 AI-generated ideas, each with a Vibe Score and radar chart.
5. Save ideas you like, then drill into any idea for PRD, tasks, research, or validation.

The entire process takes under two minutes. Your first generation costs 1 credit, and Free tier accounts start with 3 monthly credits.

• Cost: 1 credit per batch
• Follow-up questions: After the wizard, the AI may ask clarifying questions to refine results before generating

---

4. Features -- Vibe Score System

Every generated idea receives a Vibe Score -- a multi-dimensional rating that helps you compare ideas at a glance. The score is composed of five dimensions, each rated from 1 to 10.

The Five Dimensions

Radar Chart Visualization

Each idea displays a radar chart with five axes (labeled Market, Competition, Complexity, Vibe, Money) that provides an immediate visual comparison of strengths and weaknesses. The chart is interactive and appears on idea cards, the idea detail page, and the swipe interface.

Overall Vibe Score

The overall Vibe Score is a weighted composite of the five dimensions, displayed as a single number from 1.0 to 10.0. Color coding provides instant feedback:

• 8.0+ (green) -- Excellent
• 6.0-7.9 (blue) -- Good
• 4.0-5.9 (amber) -- Fair
• Below 4.0 (red) -- Needs work

---

5. Features -- Idea Detail Page

Selecting an idea opens its detail page with comprehensive information and action buttons.

Content Displayed

• Title and elevator pitch -- the core concept in one line
• Category, industry, and complexity badges -- quick reference labels
• Full description -- expanded explanation of the idea
• Vibe Score -- overall score with color-coded label (Excellent/Good/Fair/Needs Work)
• Radar chart -- five-dimension visualization
• Individual dimension ratings -- each of the five scores with labels and tooltips
• Tech stack recommendations -- organized into four groups:
  • Frontend (e.g., Next.js, React, Tailwind CSS)
  • Backend (e.g., Node.js, Supabase, Express)
  • Database (e.g., PostgreSQL, Redis)
  • Hosting (e.g., Vercel, AWS, Railway)

Action Buttons

Community Features

• Publish to Community toggle -- make your idea visible in the community feed for others to vote on
• Like / Super Like buttons -- save ideas to your collection with different priority levels

6. Features -- PRD Generation

Generate a structured Product Requirements Document from any saved idea.

What It Produces

A PRD of approximately 1,500 words covering:

• Product overview -- problem statement and proposed solution
• User stories -- specific use cases from the target audience perspective
• Core features -- prioritized feature list for the MVP
• Technical architecture -- recommended system design and technology choices
• MVP scope -- clear boundaries for the minimum viable product
• Success metrics -- measurable goals for launch and growth

Technical Details

The PRD streams directly to your browser as it is generated. You can watch the document build in real time and begin reading before generation completes.

---

7. Features -- Task Generation

Convert a PRD into an actionable implementation plan.

What It Produces

A developer-ready task breakdown that includes:

• Ordered task list -- sequential implementation steps
• Task descriptions -- what each task involves and why
• Technical details -- specific files, APIs, or components to create
• Dependencies -- which tasks must complete before others can start
• Estimated effort -- relative sizing for each task

Technical Details

Tasks are structured for direct export to project management tools (see Section 12: Export).

---

8. Features -- Market Research

Run AI-powered market analysis backed by real-time web search data.

Two Research Tiers

How It Works

1. VibeGen uses the Tavily API to perform real-time web searches related to your idea's title, industry, and category.
2. Basic tier runs 3 search queries; Pro tier runs 6 queries for deeper coverage.
3. Search results are fed to Claude Sonnet 4.6 as context for structured analysis.
4. The output is region-specific, using your target market setting to focus competitor and trend data on the relevant geography.

Research Output Structure

• Competitors -- existing products in the space with positioning analysis
• Market trends -- current and emerging trends relevant to the idea
• Opportunities -- gaps in the market you can exploit
• Niche description -- concise definition of your market niche
• Opportunity summary -- high-level assessment of the opportunity
• SEO keywords (Pro only) -- search terms with volume indicators
• Social buzz (Pro only) -- relevant social media discussion and sentiment
• TAM/SAM/SOM (Pro only) -- total, serviceable, and obtainable market estimates
• Revenue estimates (Pro only) -- benchmark revenue data for similar products

Technical Details

9. Features -- Idea Validation

Simulate customer interviews to gauge demand before you build.

What It Produces

• Simulated customers -- fictional but realistic personas from your target audience, each providing a verdict on whether they would use/pay for the product
• Verdicts per customer -- Definitely, Probably, Maybe, Unlikely, or No
• Sentiment score -- an overall sentiment rating from 1 to 10
• Key insights -- an array of actionable takeaways from the simulated interviews

Why a Different AI Model

Validation uses OpenAI GPT-5 mini (gpt-5-mini) rather than Claude. Using a separate model provider for validation reduces confirmation bias -- the model that generated the idea is not the same model evaluating it.

Technical Details

You can optionally override the target audience for a specific validation run to test the idea against a different market segment.

10. Features -- Discover / Swipe

Browse and save ideas from the community using a swipe-based interface.

Interface Layout

The swipe page has two tabs:

• Discover -- a card stack of published community ideas, presented one at a time
• Saved -- your collection of liked and super-liked ideas

Actions

Each card displays the idea title, elevator pitch, category, industry, complexity badge, Vibe Score, and a radar chart.

Daily Swipe Limits

16. Why VibeGen -- Competitive Advantage

Competitor Comparison

What Sets VibeGen Apart

1. The only all-in-one idea-to-implementation platform. Other tools handle one piece of the puzzle. VibeGen covers the entire pipeline: idea generation, scoring, market research, validation, PRD, and task breakdown -- all in one place.

2. Developer-native exports. Export PRDs and tasks directly to GitHub Issues, Linear, Jira, or Notion. No copy-pasting between tools. Your implementation plan lands in your existing project management workflow.

3. Region-specific idea generation. Choose from 7 target market regions. Ideas, market research, and validation are tailored to the regulatory environment, market dynamics, and consumer behavior of your selected region.

4. Multi-dimensional Vibe Score. Five independent dimensions (Market Potential, Competition Level, Technical Complexity, Vibe Codeability, Monetization Potential) with radar chart visualization. Compare ideas objectively rather than relying on a single score.

5. Swipe and discover with community voting. Browse community ideas in a card-stack interface. Like, super-like, or skip. Community voting surfaces the ideas other builders find valuable.

6. Streaming AI responses. All AI-generated content streams token-by-token to your browser. Start reading PRDs and research results immediately instead of waiting for the full document.

7. Competitive credit-based pricing. Start free with 3 monthly credits. Paid tiers range from EUR 12 to EUR 79 per month. Credits never expire. Failed generations are automatically refunded.

8. Full pipeline from concept to code. Idea generation feeds into market research, which informs validation, which produces a PRD, which breaks down into tasks. Each step builds on the previous one, giving you a complete path from concept to code.

18. FAQ

General

What is VibeGen? VibeGen is an AI-powered SaaS platform that helps indie hackers and solopreneurs generate project ideas, validate them, create PRDs, and produce implementation task lists -- all in one workflow.

Do I need technical knowledge to use VibeGen? No. VibeGen adapts to your skill level (Beginner, Intermediate, Advanced). Beginners receive simpler ideas with more guidance. Advanced users get more complex suggestions with detailed technical architecture. However, the generated PRDs and task lists are most useful if you have some development experience or are working with a developer.

What languages is VibeGen available in? The interface is available in English (default) and Lithuanian.

Credits and Billing

What happens to my credits if I do not use them? Unused credits roll over indefinitely. Credits from your monthly subscription allotment and purchased credit packages never expire.

What if an AI generation fails? Credits are automatically refunded to your balance if a generation fails due to a network error, model error, or timeout. You are never charged for unsuccessful generations.

Can I switch between monthly and annual billing? Yes. You can switch billing intervals from the Credits page. Annual billing provides approximately 17% savings compared to monthly billing.

Is there a free trial for paid tiers? The Free tier with 3 monthly credits serves as the trial. You can explore idea generation, validation, and basic market research before upgrading.

Ideas and Generation

How many ideas does each generation produce? Each generation produces 3 to 5 ideas based on your wizard selections.

Can I regenerate ideas with the same preferences? Yes. After viewing results, you can generate another batch with identical preferences or start the wizard over with new selections.

Are my ideas private? By default, all ideas are private and visible only to you. You can optionally publish individual ideas to the Community feed using the publish toggle on the idea detail page.

What AI models does VibeGen use? VibeGen uses multiple AI models for different tasks: Claude Haiku 4.5 for fast idea generation, Claude Sonnet 4.6 for PRDs, tasks, and market research, and GPT-5 mini for validation. Using different models for generation and validation reduces confirmation bias.

Data and Privacy

Can I export all my data? Yes. The Settings page includes a GDPR-compliant data export button that downloads all your data (ideas, PRDs, tasks, research, and profile information) as a JSON file.

How do I delete my account? From the Settings page, use the "Delete account" button in the danger zone. This initiates a 30-day grace period during which you can cancel the deletion by signing back in. After 30 days, all data is permanently removed.

Is my data used to train AI models? Your ideas and generated content are not used to train AI models. Data is processed through Anthropic (Claude) and OpenAI (GPT) APIs under their respective data processing agreements, which do not use API data for model training.

Technical

Why do AI responses stream instead of loading all at once? Streaming delivers content token-by-token as it is generated. This lets you start reading immediately rather than waiting 10-30 seconds for the full response. It also provides visual feedback that the generation is working.

Which export formats are available on which tiers? Clipboard and Markdown export are available on all tiers including Free. PDF export requires Starter or above. Notion, GitHub Issues, Linear, and Jira exports require Pro or above.
