I will develop a custom ai chrome extension with manifest v3
Pankaj
About this gig
I develop custom Chrome, Edge, and Brave extensions with Manifest V3, polished UI, secure permissions, and reliable integrations.
What I can build:
- AI assistants, side panels, popups, and content scripts
- ChatGPT, Gemini, Claude, Grok, or custom LLM integrations
- Page-aware chat, document processing, summaries, and translation
- Workflow automation, data extraction, and notifications
- Authentication, subscriptions, and third-party APIs
Why work with me:
I built PikuZen AI, StylixAI, and HeyGeniereal browser extensions with multi-provider AI, smart drafts, voice, page context, website restyling, Sign Up / Sign In and subscription flows. I also created Proxima, a multi-AI MCP platform with 5,000+ users and 1.2K+ GitHub stars.
Q: Do users need their own AI API keys?
A: Not necessarily. I can build the extension so users connect through their AI account they are already logged into in their browser such as ChatGPT, Gemini, Claude, Grok, or another supported provider, also allow each user to securely add their own API key, or route requests through an API hosted on your backend.
You receive tested source code, setup instructions, clear communication, and post-delivery support.

I turn ambitious AI ideas into polished, production-ready products.
I built Proxima, a 1.2K+ star multi-AI MCP platform; Halo AI for document intelligence; HeyGenie for webpage, document and live-voice assistance; PikuZen for multilingual social writing; and StylixAI for prompt-based website customization.
I handle the full journey—from architecture and UI/UX to AI integrations, Node.js, Python, Electron, APIs, testing and deployment. If you need an AI SaaS platform, developer tool, desktop app or browser extension, I can build it from idea to launch with clean, scalable code.
