How I Built a Free AI Tool to Turn Videos into Subtitles, Transcripts & Summaries Instantly

If you’ve ever tried extracting subtitles, transcripts, or summaries from videos or podcasts, you know how frustrating it can be. Most tools either require a paid subscription, force you to upload files to third-party servers, or provide clunky, inaccurate results.

That’s exactly why I built AI Video Summary — a free, privacy-first web app that transforms your audio or video content into accurate .srt subtitles, full-length transcripts, and AI-generated summaries in seconds.

🧠 What is AI Video Summary?

AI Video Summary is a simple tool designed for creators, educators, researchers, and developers who want quick, accurate transcriptions and summaries from their files. It supports .mp4 and .mp3 formats, and offers:

• Subtitles in .srt format

• Full transcripts (punctuated, structured)

• AI-generated summaries using natural language processing

No sign-up. No file storage. No nonsense. Just results — instantly and privately.

🔧 Why I Built This

As a content creator and developer, I was tired of bloated transcription software and privacy concerns. I didn’t want to upload files to someone else’s cloud or worry about hidden limits or paywalls.

I also noticed many developers and educators needed lightweight tools that “just work” — especially when preparing subtitles, notes, or summaries for documentation, lessons, or meetings. So, I built one.

🏗️ Under the Hood: Tech Stack

Here’s how AI Video Summary works behind the scenes:

• Frontend: React + Vite + Tailwind CSS

• Backend: Flask (Python)

• Transcription Engine: OpenAI Whisper

• Summarization Engine: Facebook BART

• Hosting: Contabo VPS

• Privacy: 100% local processing — no data is saved or stored

The combination of Whisper and BART makes it extremely accurate and surprisingly fast. Whisper handles multilingual transcription beautifully, while BART condenses speech into readable summaries.
