Can PlugThis rebuild PopAi - Your Personal AI Assistant?
“It is just a PDF viewer hooked up to standard multimodal LLM APIs.”
PopAi extracts text and images from web pages or PDFs and sends them to standard vision-enabled AI models. You can easily build this using Chrome's side panel API, an open-source PDF parser like PDF.js, and your own OpenAI or Gemini API key. There are no proprietary models or locked datasets involved.
What you'd plug into
Multimodal text and image analysis for PDFs and pages
Client-side PDF rendering and text extraction
Why build your own PopAi - Your Personal AI Assistant alternative
- Pay raw API rates instead of high monthly subscription fees
- Complete privacy: your documents and queries stay strictly between you and your AI provider
- Freedom to choose any vision or text model (Claude 3.5 Sonnet, GPT-4o, Gemini 1.5 Pro)
- No artificial usage limits or query throttles
What it costs vs what you'd save
The original: Free tier with premium subscription plans around $10 to $20/month
Your version: Switching to your own API key turns fixed monthly SaaS costs into cents per hundred document queries.

Questions about rebuilding PopAi - Your Personal AI Assistant
How does document chat work inside a custom extension?
The extension uses PDF.js to extract text client-side, splits it into readable chunks, and sends relevant context along with your prompt to your LLM of choice.
Can my extension handle image recognition like PopAi?
Yes. Multimodal models like GPT-4o or Claude 3.5 Sonnet accept base64-encoded screenshots and document images directly through their standard REST APIs.
Do I need a server to store document history?
No. You can store chats and summaries locally in chrome.storage.local or connect Supabase if you want synchronized history across devices.
