Why Buyers Like It

A compact feature set that demos well and ships easily as a static tool.

Sell-Ready

1. Single-file deployment with no backend required.

2. Platform-specific caption generation for Instagram, Twitter, LinkedIn, Facebook, and TikTok.

3. Demo fallback included, so the app still showcases value without a live API call.

4. Copy-per-caption, Copy All, and CSV export make it easy to hand off usable output.

Privacy & Trust

Position the app clearly for clients who care about where prompts and keys go.

Client-Safe

This app runs fully in the browser. It does not include a backend, database, or built-in key storage.

Gemini requests are sent directly from the page to Google using the user’s own API key.

The app attempts the requested Flash model first and automatically falls back to a newer supported Flash model when Google rejects older availability.
