I rebuilt Natively's voice AI copilot as a free browser demo

I am a school teacher from Pakistan, not a software engineer. I build free tools with AI assistance, and this one is a rebuild of Natively's real-time voice AI copilot — the kind of tool that listens while you talk and answers live, useful for interviews and meetings.

Try it: https://natively-clone.pages.dev/
Code: https://github.com/zhbhaider-coder/natively-clone

What it does

Open the demo, allow the microphone, and it listens and answers live while you talk. It uses the Web Speech API for the mic, and the answers come from your own key — paste a free Gemini or OpenAI key once and it stays in your browser's localStorage. Nothing about your key or your audio goes to a server of mine, because there is no server.

The page lists the tiers for reference — Free BYOK at $0, then Standard $8, Pro $15, Max $25, Ultra $35, and a Pro licence at $39/year or $79 lifetime. The demo itself is free with your own key.

Why it is free

Same reason as my other tools: there is no backend. The page is static HTML/CSS/JS on Cloudflare Pages, the mic is a browser API, and the AI call goes straight from your browser to Google or OpenAI. Measured about 70x lighter than the original site — not a speed claim, just a smaller page, which is why it loads fast.

What it honestly cannot do

It is a demo rebuild, not the original — unofficial, and not affiliated with Natively. It needs mic permission and your own key. Speech recognition quality depends on your browser (best in Chrome). It will not coach you like a human would; it answers, you talk, that is the loop.

How it is built

Static page, Web Speech API for recognition, fetch calls to the Gemini/OpenAI APIs with the key from localStorage. No database, no tracking, no accounts.

What is next

If you try the demo, tell me one thing: does the live answer feel fast enough to talk over, or does the lag break the conversation? That is the question I cannot answer alone, and it decides what gets built next.

I am a teacher who builds tools, not a company. If this saves you one subscription, it did its job.
