Overview

DocCrafter is a modern, AI-powered documentation platform designed to turn raw project details into fully structured, export-ready documents within minutes. It removes the repetitive, time-consuming parts of documentation and replaces them with an intelligent, guided workflow that generates clear, well-organized content instantly.

What Users Can Do

Smart Q&A Flow

Start by entering basic project details. DocCrafter then asks dynamic, context-aware follow-up questions to gather deeper information without overwhelming the user.

AI-Generated Document Structure

Based on the collected inputs, the platform automatically creates a chapter-wise structure tailored to the project type — whether technical, business, or academic.

Content Generation with Gemini

Each chapter is expanded into accurate, domain-specific content using Google’s Gemini model, ensuring the tone, depth, and terminology match the project’s context.

Live Preview & Export

Users can view the documentation in real time and export it instantly in DOCX or HTML formats.

Why I Built This

Documentation is essential in every project, but it often becomes the most delayed and neglected task. I wanted to eliminate that friction by creating a system that:

  • Collects project information through an intelligent, conversational flow
  • Automatically generates structured chapters
  • Produces high-quality content instantly
  • Removes writer’s block entirely
  • Gives users full control over tone, detail, and output

If design and testing can be automated, documentation should be too — that’s the idea behind DocCrafter.

Tech Stack

  • Next.js 15 and React 19 for a fast, modern frontend
  • Google Gemini API for generating high-quality, domain-specific content
  • MongoDB + Mongoose for managing project data
  • Clerk for authentication
  • Inngest for background AI job processing
  • Azure Blob Storage for asset storage

Challenges & Learnings

Building a flexible question engine that adapts to any project type — from SaaS apps to academic theses — was the toughest challenge. Balancing AI-generated structure with user customization was also essential to avoid rigid outputs. Securing and optimizing Gemini API usage led to the introduction of Bring Your Own API Key, giving users full scalability at minimal cost.

Outcome

DocCrafter has transformed how I create documentation. Work that previously took hours or days now takes minutes, with consistent formatting and no creative friction. With the ability to use personal Gemini API keys, the platform is scalable, accessible, and ready for real-world use.
