Multi-Model AI Platform for Smarter AI Comparisons

A full-stack SaaS AI platform that compares OpenAI, Claude, and Gemini responses side by side through parallel processing, independent streaming, and intelligent usage management.

Overview

Prompt.me is a multi-model AI SaaS platform that enables users to submit one prompt to multiple AI models simultaneously and compare their responses in one interface. Built with Next.js, TypeScript, Firebase, Clerk, and Stripe, the platform integrates OpenAI, Anthropic Claude, and Google Gemini through a unified AI orchestration layer. It supports independent response streaming, provider-level error handling, token and cost tracking, credit-based usage metering, and subscription billing.

Problem Statement

Fragmented AI Model Access

Users needed a more convenient way to compare responses from different AI providers without switching between separate tools and interfaces.

Slow and Unreliable AI Responses

Sequential requests and provider delays could increase waiting times, while a single failed API request could disrupt the overall comparison experience.

Complex AI Usage and Cost Management

Different model pricing and token consumption required accurate usage tracking, balance validation, and credit deductions to manage AI costs effectively.

Subscription and Data Management

The platform needed integrated authentication, secure user-scoped data, conversation history, and subscription billing to support a reliable AI SaaS experience.

Solution Statement

Unified Multi-Model AI Integration

Developed a shared provider abstraction for OpenAI, Claude, and Gemini, standardizing model requests, streaming output, errors, timeouts, and usage data.

Parallel Streaming and Fault Isolation

Implemented concurrent model requests with independent response streams, provider-specific timeouts, and failure isolation so one unavailable provider would not block others.

Credit-Based Usage and Cost Tracking

Built model-specific pricing, pre-request balance validation, token tracking, credit deductions, and usage records to connect AI consumption with account balances.

Integrated SaaS Accounts and Billing

Connected Clerk authentication, Firestore persistence, and Stripe subscriptions to support account management, conversation history, and subscription-based access.
