FAQ
How do you ensure the extension complies with Chrome Web Store policies?
I build strictly following Manifest V3 guidelines with minimal permission scopes, zero remote/eval code, and robust Content Security Policies (CSP). This ensures your extension is store-ready and structured to meet Google's strict review criteria.
Do I need to pay for AI API keys (Gemini, Claude, OpenAI)?
We can build two models: 1. BYOK Model: Users provide their own API key ($0 API cost to you). 2. Backend SaaS Model: Keys live securely in the backend, allowing you to track per-user quotas, set rate limits, and charge paid monthly subscriptions via Stripe.
Will I receive the complete source code and documentation?
Yes, 100%. You receive the complete, well-documented TypeScript/React codebase, build scripts, asset folders, and a step-by-step setup guide for local development and store submission.
Can you connect the extension to my existing database or API?
Absolutely. I can connect your extension to any custom REST API, GraphQL endpoint, Supabase, Firebase, or external CRM with secure authentication tokens.
