PERPLEXITY HACKATHON — LONDON, UK  

We’re hosting the first-ever Perplexity Hackathon in the UK, powered by the Perplexity API Platform.  

Join developers, researchers, and innovators for 24 hours of creativity, curiosity, and collaboration.

At this in-person hackathon, you’ll build applications that explore, reason, and answer questions using the Perplexity API Platform — the same technology that powers millions of Perplexity queries daily.  

Advanced offerings—such as reasoning, research, and multi-step planning—allow developers to build custom agents that support follow-up questions and expose chain-of-thought.

We’re looking for developers to push the boundaries of what’s possible with the Perplexity API Platform and dream up entirely new product categories. If you’ve been thinking about shipping the “Perplexity for ____,” there’s never been a better time to start building.

Check out the following:

Requirements

🧩 What to Build

Participants are challenged to build projects that leverage the Perplexity API Platform to create tools, agents, or applications that inspire curiosity, deepen understanding, or help people reason through complex topics.

Your project should:

  • Integrate at least one capability from the Perplexity API Platform

  • Demonstrate meaningful or creative use of Perplexity’s API for real-world exploration, research, or knowledge discovery.

  • Be functional, original, and developed primarily during the hackathon.

  • Address a real problem, use case, or opportunity where AI-powered reasoning or search can make a difference.

Example ideas include:

  • AI research assistants or tutors that guide users through complex subjects

  • Interactive knowledge tools that surface trusted information from live search

  • Developer agents or productivity tools powered by natural language reasoning

  • Custom interfaces or products that extend the “Perplexity for ___” concept

Whether you build a browser tool, chatbot, mobile app, or backend system, the goal is to create something that helps people ask better questions — and get better answers.

📦 What to Submit

To qualify for judging, each submission must include:

  1. A working project built using the Perplexity API Platform

    • The project should run consistently on its intended platform and function as described.

    • If it’s hosted privately, include demo credentials or a live link for judges.

  2. A public code repository (GitHub)

    • Must include a README.md with setup instructions and dependencies.

    • The README should briefly explain how the Perplexity API was integrated.

  3. A demo video (max 5 minutes)

    • Show your project in action.

    • Upload to YouTube or Vimeo (public or unlisted) and include the link on Devpost.

  4. A written summary (200–300 words)

    • Describe your project’s purpose, technical approach, and use of the Perplexity API.

    • Explain the reasoning or retrieval capabilities used and their impact.

  5. Team details

    • Include names, roles, and LinkedIn profiles of all contributors.
