Cortona's Vision

Inspiration

I’ve spent years saving videos—from TikTok, YouTube, and educational platforms—with the intention of organizing and using them to create content or share insights. But I kept running into the same problem: too many videos, not enough time to rewatch or extract value.

I wanted a tool that could help me transform video into usable knowledge—summarized, searchable, and shareable—with minimal friction. That’s where Cortex Companion was born.

What it does

• Accepts any video link or pasted transcript
• Summarizes the content instantly with AI (OpenAI GPT-4)
• Lets the user ask questions about the video
• Generates social media captions or content ideas based on the video
• Built entirely in Bolt.new with external AI integrations via webhook

How we built it

• Frontend built using Bolt.new
• All video summarization and content generation is handled via OpenAI’s GPT-4 API
• Prompts were designed in advance and passed through a webhook using Make.com
• Deployed via Bolt’s built-in preview + backup Netlify link
• UI was kept minimal for fast interaction: 1 input box, 2 action buttons, and a chat log

Challenges we ran into

• Bolt.new doesn’t support file/image uploads, so we focused on paste-based interactions
• Some image embedding and persistent data logic had to be moved off-platform
• Time limits made us narrow to a “Lite” version of our long-term vision
• GPT context limitations required us to simplify how summaries and Q&A worked

Accomplishments that we're proud of

✅ Built a fully functional AI assistant in under 2 hours using Bolt.new (TRUST ME)

• ✅ Created a simple, intuitive experience that turns any video into usable insight
• ✅ Seamlessly integrated OpenAI GPT-4 for summarization, Q&A, and content generation
• ✅ Designed prompts and flows that feel like a real assistant—without needing a database
• ✅ Overcame Bolt.new limitations by cleverly using external hosting and prompt-based logic
• ✅ Delivered an MVP that reflects a much larger long-term vision for creators and learners

What we learned

• Bolt.new is amazing for UI prototyping but has hard limits (no file storage, limited state)
• Real-time AI use cases don’t need a lot of code—just the right flow
• MVP ≠ incomplete; it’s focused

What's next for Cortona's Vision

• Add voice interaction for a full Cortana-style experience
• Organize saved videos into smart folders with AI auto-tagging
• Add timeline playback or highlight reels from long-form content
• Turn this into a personal AI system for content creators and knowledge workers
