Stop buying prompts. Start enhancing yours.
PromptBase sells 270,000+ prompts at $1.99–$19.99 each. PromptAI enhances whatever you type into a structured, role-aware prompt in under a second — no marketplace browsing, no stale templates, no per-prompt fees. Flat rate from $7.99/month.
PromptBase is a prompt marketplace — you browse and buy prompts written by others. PromptAI is a prompt enhancer — you write your own task in plain language and it builds the structure for you. Different model, different audience.

When PromptBase is the right pick
PromptBase is genuinely useful if your primary need is image-generation prompts — Midjourney, Stable Diffusion, DALL-E 3. The marketplace has over 270,000 prompts with example outputs you can preview before buying, and many creators have refined their prompts for months. For creative image work where exact style replication matters, buying a well-crafted Midjourney prompt can be worth $3–5. PromptAI focuses on text-based AI tools and does not currently offer image-gen prompt optimization.
When PromptAI wins
You work with text AI tools — ChatGPT, Claude, Gemini, or developer tools like Cursor and Claude Code. You enhance prompts more than 5–10 times a month, making a flat $7.99 subscription cheaper than per-prompt purchases. You want in-place enhancement — no bouncing between a marketplace and your AI chat. And you want prompts tuned to your exact task, not written for a generic use case six months ago.
Instant, in-place
No marketplace tab. No copy-paste. PromptAI's floating button lives inside ChatGPT, Claude, Gemini, and Perplexity — type, enhance, send.
Every AI, one account
Chrome extension for web AI tools. Mac desktop app for Claude Code, Cursor, Warp, VS Code — triggered by ⌘⇧P from anywhere.

PromptAI does not store your prompts, does not sell them, and does not train on them. See promptai360.com/privacy.
