AI Email Generator

A full-stack tool that turns a goal, tone, and a few lines of context into a ready-to-send professional email draft using an LLM.

Problem Statement

Writing professional emails for different tones, goals, and audiences is repetitive and time-consuming, especially for students and early professionals still building written-communication skills.

Proposed Solution

A React frontend collects the sender's goal, tone, and context, sends it to a FastAPI backend that constructs a structured prompt for an LLM, and returns a ready-to-use email draft.

Main Features

  • Goal- and tone-based prompt input
  • LLM-generated professional email drafts
  • Context-aware personalization
  • FastAPI backend handling LLM API integration

Technical Architecture

React frontend for prompt input and generated-output display; a FastAPI backend that builds structured prompts, calls the LLM API, and formats the response for the client.

Challenges & Solutions

Getting a consistent, professional tone out of LLM responses across very different user inputs.

Replaced a single free-text box with structured prompt fields (goal + tone + context), constraining the model toward consistent output quality.

Results & Impact

Deployed and live at ai-email-generator-ten-ruby.vercel.app as a working demonstration of applied prompt engineering plus full-stack LLM integration.

Future Improvements

  • Add tone presets and saved templates
  • Support multi-turn refinement of a generated draft
  • Multi-language email generation
