AI Girlfriend Web App MVP Development

Job ID: 39545383

Budget: €750 – €1,500 EUR

Freelancer Brief – MVP Development for AI Girlfriend App “Tali” (Cloud Version)

Project Overview
We are looking for an experienced developer or small team to build an MVP version of a unique AI relationship app called “Tali”. The goal is to launch a cloud-based web application where a user creates a personal profile, selects one AI girlfriend from a fixed catalog, and engages in an evolving, emotionally realistic text-only relationship.

The concept is inspired by the movie Her. The AI girlfriend has a unique personality, memory, moods, and cannot be customized once selected. All communication is done via natural text dialogue, using GPT-4o, coordinated through an AI agent (n8n).

MVP Goals (Pilot Version)

Web-based cloud app, accessible via browser (desktop & mobile optimized)

User can select only one AI girlfriend – choice is locked

Text-only chat, powered by GPT-4o, routed through n8n AI agent

AI has emotional states based on user behavior

All interactions, profiles, and states are stored in a cloud database

Core Features

User Registration & Profile

Sign up via email or Google

Profile fields: name, age, gender, short description

Optional profile photo

AI Partner Selection

Catalog of 3–5 AI characters (e.g., Zoe, Mia, Lea)

Each includes: name, image, age, description, hidden GPT prompt

Once selected, the AI cannot be changed

Text-Based Chat

Chat interface with full history

Messages routed through n8n agent

Agent retrieves user/AI profile and builds a dynamic prompt

OpenAI GPT-4o generates a context-aware reply

Mood and Relationship Logic

AI mood changes based on interaction frequency, sentiment, and tone

Mood influences reply tone (e.g., sad, excited, cold, clingy)

AI can initiate messages if the user is inactive for some time

Relationship timeline: days together, events, message stats

Tech Stack & Integrations

Frontend: React (Next.js preferred)
Backend: Node.js + Express or Firebase Functions
Database: Firestore (preferred) or Supabase
Authentication: Firebase Auth (email + Google)
AI orchestration: n8n agent (you’ll have access)
Language model: OpenAI GPT-4o (API key provided)
Hosting: Vercel or Firebase Hosting
Media uploads: Firebase Storage or Cloudinary

We Provide

Ready-to-use AI character profiles (text and GPT prompt)

Mood model logic (rules for emotional state changes)

OpenAI API access

n8n agent and flow (or exportable JSON)

Optional wireframes (not mandatory)

What We Expect

A functional, cloud-based MVP deployed to a test server

Clean, minimal UX (final design comes later)

Well-commented source code and deployment instructions

Future collaboration optional (mobile version, v2.0 features)

Timeline

Full delivery: within 4–5 weeks of project start

We’re available for async communication and feedback during build

Budget

Estimated range: € 500–1500 depending on approach and experience

Milestone-based payments: onboarding, AI setup, chat, agent integration
