What Are the Differences Between Prompt Anything Pro Free and Pro?
Prompt Anything Pro's free tier gives you 7 prompts/week with GPT-4o mini, Claude Haiku, and Gemini Flash to evaluate the BYOK (Bring Your Own Key) workflow. Pro unlocks unlimited prompts, all frontier models (GPT-4o, Claude Sonnet, Claude Opus, Gemini Pro), unlimited templates, conversation history, and export. Pricing: $6.99/month, $29.99/year, or $49.99 lifetime — and because Pro is BYOK, you pay raw API rates (often a few tenths of a cent per prompt) instead of the $10–$19/month markups competitors charge.
- Free tier: 7 prompts/week, GPT-4o mini + Claude Haiku + Gemini Flash, text selection prompting, 5 saved templates — no credit card.
- Pro unlocks unlimited prompts, all frontier models (GPT-4o, Claude Sonnet, Claude Opus, Gemini Pro), unlimited templates, conversation history, Markdown/JSON export.
- Prompt Anything Pro is BYOK — your own OpenAI/Anthropic/Google key. You pay raw API rates, typically fractions of a cent per prompt, instead of the $10–$19/month subscription markups competitors like Sider, Monica, or Merlin charge.
- Pricing for the extension itself: $6.99/mo, $29.99/yr, or $49.99 lifetime — one-time, no renewals, no per-model surcharges.

The Numbers Behind This Answer
Every figure below cites a primary source. Click through to verify.
Approximate raw API cost of a single typical paragraph-length prompt-and-response on GPT-4o or Claude Sonnet at published per-million-token rates. Heavy daily users in the BYOK model often pay less in total API + extension fees than a single month of Sider/Monica/Merlin's subscription tiers.

Typical subscription markups charged by competing AI-on-webpage extensions (Sider ~$10/mo, Monica ~$19/mo, Merlin ~$19/mo) on top of the underlying model costs. Prompt Anything Pro's BYOK model removes this middle layer entirely.
