Telegram PDF Summarizer: AI-Powered Document Assistant

The Telegram PDF Summarizer is a stateless AI bot that turns dense PDFs into concise, readable summaries — delivered directly inside chat. No installs, no databases, no waiting. Just upload, and get insights in seconds.

I created this project to showcase how AI and automation can make information more accessible. The design emphasizes speed, privacy, and scalability, ensuring anyone can use it without friction.

Key highlights:

Seamless user flow: Upload a PDF → bot validates → extracts text → generates summary → delivers result.

Privacy-first design: Stateless, no database, no data retention.

Customizable output: Summaries can be tuned for length, language, and tone.

Error-resilient workflow: Each step includes validation and clear feedback.

Scalable foundation: Ready to extend with OCR, cloud storage, or integrations.

Built with BuildShip workflows and OpenAI APIs, the system is fully modular and production-ready.

Trigger: Telegram Webhook → Validate PDF → Retrieve file.

Parser: Secure local parsing for text extraction.

Summarization: AI-powered summaries via OpenAI Responses API with configurable settings.

Delivery: Chunked messages for smooth Telegram output.

Tech highlights: ✔️ Safe PDF parsing with token protection. ✔️ Flexible AI summarization (language, bullets, tokens). ✔️ Modular workflow architecture for easy feature expansion.
