Introducing ZapBrain
Chat with online articles, PDFs, and YouTube videos on WhatsApp.

Information is everywhere, but often locked inside long articles, academic papers, or dense documents. Finding the insights you need takes time, focus, and endless scrolling.
ZapBrain changes that.
Our AI agent transforms documents and links into conversations. Just share a web article, a PDF, or a YouTube video on WhatsApp, and ZapBrain will give you clear, instant answers.
How it works
Share your content: Send a link, upload a PDF, or paste a YouTube video.
Ask questions: What’s the main idea? Can you summarize it? How does this compare to X?
Get instant insights: Instant summaries, key takeaways, and references directly in WhatsApp.
Why it Matters
ZapBrain helps you:
- Save hours of reading and searching
- Study smarter with concise, AI-powered summaries
- Unlock knowledge from any source, in any language
What's next
We're just getting started. Soon, ZapBrain will:
- Support more formats: Go beyond PDFs to include DOCX, PPT, PNG, and JPG.
- Offer voice interaction: Listen to summaries and ask follow-up questions in real time.
- Unlock mind maps: Visualize ideas and connections as interactive maps inside WhatsApp.
This is only the beginning of bringing AI agents to WhatsApp, making everyday learning faster, simpler, and more accessible.
Our purpose
At IndiGo, we believe AI should serve everyone. That’s why every agent we create, including ZapBrain designed to make knowledge more accessible, and to contribute to social impact projects. By supporting ZapBrain, you also help us expand initiatives like ReviveriA, bringing AI-driven support to communities that need it most.
