AI-Powered Document Summarization

DocSummarizer is a smart, AI-powered web app built by Silver WebBuzz to help users quickly extract meaningful summaries from large documents (PDF, DOCX, TXT). Powered by Google’s Gemini generative AI, the platform allows individuals—from researchers to corporate professionals—to summarize dense text instantly and securely.

This solution eliminates the cognitive and time overhead of manual document reading, providing a scalable, intuitive interface paired with high-accuracy AI summaries.

ABOUT THE PROJECT

Project Overview

We envisioned DocSummarizer as a privacy-conscious, low-latency SaaS tool offering:

Drag-and-drop document upload (10MB limit)
Multiformat support: PDF, DOCX, TXT
Generative summaries using Gemini API
Responsive web UI with real-time feedback
Backend integration with MySQL for session logs and analytics
Support for autoscaling in production

The project’s full stack included:

Frontend: React + Tailwind CSS
Backend: Python Flask
AI: Google Gemini via google.generativeai
Database: MySQL
Deployment: Cross-platform compatible

SEE WHAT WE SOLVED

The Problem

Before the rebuild, TrackiPet faced several critical issues that limited growth and customer satisfaction:

Text Extraction from Rich Files
DOCX and PDF parsing was complicated by formatting artifacts, tables, and symbols. Ensuring clean, semantically useful plain text for the AI model took multiple iterations using PyPDF2 and python-docx.

Handling Large File Sizes and Timeouts
Gemini API calls with long text required splitting the document into manageable parts while preserving context. We implemented chunk merging logic to present cohesive summaries from segmented inputs.

Client-Server Synchronization
Managing real-time UI state updates during long-running summarization required frontend resilience and user feedback mechanics (e.g., loading spinners, disable buttons, retry logic).

Data Security & Upload Handling

The app handles user documents securely using Flask’s secure_filename and temporary uploads directory. We also implemented file size caps and type filtering to avoid injection and misuse.

Cross-Browser Styling & Mobile Responsiveness

Achieving a consistent, elegant experience across screen sizes meant heavy use of Tailwind CSS utility classes, mobile-first breakpoints, and accessibility-first development practices.

CHALLENGES WE HAD

The Solution

To address the above, Silver WebBuzz engineered an optimized workflow:

Intelligent Text Extraction
We built robust parsers using PyPDF2 and python-docx to extract clean, readable text from diverse document formats while filtering out visual noise and formatting artifacts.

Chunked Gemini Summarization
To handle large documents efficiently, we implemented a smart chunking and merging logic that feeds text segments to Gemini’s API while maintaining context for coherent summaries.

Secure Upload & File Handling
User files are processed securely using Flask’s secure_filename with temporary storage. Files are filtered, size-checked (10MB max), and auto-deleted post-summarization for privacy.

Prompt Engineering for Accuracy
We designed structured prompts tailored to Gemini’s model behavior, enhancing the relevance and structure of AI-generated summaries across use cases like academic, legal, and business docs.

Streamlined UI/UX with Tailwind
Using React and Tailwind CSS, we created a fast, responsive interface with real-time feedback, drag-and-drop uploads, and user-friendly summary displays across all devices.

FINAL MILESTONE

The Result

After deployment and refinement, DocSummarizer delivered:

Instant Summaries Under 10 Seconds
Users receive accurate, AI-generated summaries in less than 10 seconds for documents up to 10MB, ensuring a fast and productive workflow.

92%+ Summary Accuracy
Through Gemini prompt tuning and chunk merging, the platform delivers summaries that maintain over 92% relevance and contextual integrity based on real user testing.

Seamless Cross-Device Experience
