anyform(AI form builder)

AnyForm is an AI powered, tool-first platform that lets you build complex, validated forms in under 30 seconds just by describing them no drag-and-drop required

Comment

Inspiration

The inspiration for AnyForm came from watching non-technical users struggle with existing form builders. Teachers wanted to create quizzes but got lost in dropdown menus. Event organizers needed registration forms but spent hours on setup. Small business owners needed contact forms but hired developers instead.

I envisioned a world where anyone could create professional, functional forms by simply describing what they need. With Google's Gemini 3 API, I could finally make this vision a reality.

What it does

AnyForm is an AI-powered form builder that transforms natural language into fully functional, production-ready forms in seconds.

Form Builder Interface

How I built it

🏗️ System Architecture:

System Architecture Diagram

The architecture consists of three main layers:

  1. Client Layer: Next.js app with React components, running on Vercel Edge
  2. AI Layer: Google Gemini 3 API for natural language processing
  3. Data Layer: PostgreSQL database with Prisma ORM

Tech Stack:

Frontend:

  • Next.js 16 (App Router) - React framework with server components
  • TypeScript - Type safety throughout the entire codebase
  • Tailwind CSS - Custom "paper wireframe" theme with hand-drawn aesthetic
  • React Hooks - State management (useState, useEffect, useCallback, useMemo)

Backend:

  • Next.js API Routes - Serverless functions deployed on Vercel Edge
  • Prisma ORM - Type-safe database access with auto-generated types
  • PostgreSQL - Production database (Vercel Postgres)
  • NextAuth.js - Authentication with Google OAuth and credentials

AI Integration (Extensive Gemini 3 Usage):

  • Google Gemini 3 API - Natural language processing and form generation
  • Gemini Pro - Text-based form generation from voice/text input
  • Gemini Vision - Image analysis for scanned forms (OCR)
  • Gemini Embeddings - Semantic search and context understanding
  • Function Calling - Structured JSON output for reliable form generation

Voice Technology:

  • Web Speech API - Browser-native speech recognition (no backend needed!)
  • Web Audio API - Real-time audio level visualization
  • Custom React Hooks - Voice state management and auto-stop logic
  • Mobile Optimizations - iOS/Android specific handling

Real-Time Features:

  • Pusher - WebSocket-based real-time collaboration
  • SWR - Data fetching with caching and revalidation

🔧 Key Implementation Details:

1. Gemini Integration Strategy:

I use Gemini 3's advanced features extensively:

  • Function calling for structured form generation (ensures consistent JSON output)
  • Multi-turn conversations for form refinement and follow-up questions
  • Large context window for complex multi-step forms
  • JSON mode for reliable parsing and validation

2. Voice Mode Architecture:

The voice mode works entirely client-side with zero backend configuration:

User Speech → Web Speech API → Text Transcript 
           ↓
Gemini 3 API → Form Structure → React Components

Key Innovation: Smart auto-stop detects 3 seconds of silence and automatically stops recording, making it feel natural and intuitive. No need to manually click "stop"!

3. Smart Form Generation:

When you describe a form, Gemini:

  • Analyzes user intent and context
  • Generates appropriate field types (text, email, number, date, dropdown, etc.)
  • Adds validation rules automatically (email format, required fields, min/max values)
  • Creates conditional logic when needed (show field X if answer Y is selected)
  • Suggests quiz scoring if educational context is detected

4. Mobile Optimizations:

iOS Safari:

// iOS doesn't support continuous mode
recognition.continuous = false;

// Auto-restart after each utterance
recognition.onend = () => {
  if (shouldKeepListening) {
    setTimeout(() => recognition.start(), 300);
  }
};

Android Chrome:

// Continuous mode works but needs restarts
recognition.continuous = true;

// Handle unexpected stops
recognition.onend = () => {
  if (shouldKeepListening && restartAttempts < 5) {
    setTimeout(() => recognition.start(), 150);
  }
};

5. Performance:

  • Lazy loading: Voice module loads on demand (~35KB, only when needed)
  • Code splitting: Separate bundles for different features
  • Debounced updates: Interim transcripts debounced to 100ms
  • Optimized audio processing: FFT size of 64-128 for efficient audio monitoring
  • Memoization: React.memo and useMemo to prevent unnecessary re-renders

📊 Data Flow:

Data Flow Diagram

Challenges I ran into

1. Gemini API Response Consistency

Problem: Gemini sometimes returned forms in inconsistent formats, making it difficult to reliably parse the output.

Solution:

  • Implemented strict JSON schema validation using Zod
  • Used Gemini's function calling feature to enforce structured output
  • Added fallback parsing with error recovery for edge cases
  • Created comprehensive prompt engineering with examples

2. Voice Recognition on Mobile

Problem: iOS Safari doesn't support continuous voice mode, causing recognition to stop after each utterance. This made the experience feel broken and frustrating.

Solution:

  • Detected iOS devices using user agent and switched to single-shot mode
  • Implemented auto-restart mechanism with 300ms delay between restarts
  • Added retry logic with exponential backoff (up to 5 attempts)
  • Created device-specific error messages for better UX

3. Real-Time Collaboration Conflicts

Problem: Multiple users editing the same form simultaneously caused data conflicts and race conditions.

Solution:

  • Implemented operational transformation for conflict-free editing
  • Added optimistic UI updates for instant feedback
  • Created conflict resolution strategy with "last write wins"
  • Added visual indicators for collaborator presence and cursor positions

4. Form Validation Complexity

Problem: Gemini generated forms but validation rules were inconsistent or missing.

Solution:

  • Created validation rule templates for common field types
  • Used Gemini to generate Zod schemas for type-safe validation
  • Implemented both client-side and server-side validation
  • Added real-time validation feedback as users type

5. Embed Security

Problem: Embedded forms needed to work across domains without security issues (CORS, XSS, etc.).

Solution:

  • Implemented proper CORS headers for cross-origin requests
  • Created iframe-based embedding with sandboxing
  • Added Content Security Policy (CSP) headers
  • Isolated embedded forms from parent page scripts

6. Performance with Large Forms

Problem: Forms with 50+ fields caused slow rendering and poor user experience.

Solution:

  • Virtualized long form lists to only render visible items
  • Lazy loaded form builder components (loaded on demand)
  • Memoized expensive computations using React.memo
  • Optimized re-renders by preventing unnecessary updates
