What exactly do I get for one credit?
Three engineering-grade prompts delivered simultaneously — one optimised for Text AI, one for Image AI, and one for Video AI. All from a single rough idea. One credit costs 10p.
Which AI tools do the prompts work with?
Every major platform. Text prompts work with ChatGPT, Claude, Gemini and any text AI. Image prompts work with Midjourney, DALL·E, Stable Diffusion, Firefly and more. Video prompts work with Sora, Runway, Kling, Pika and Luma.
Do my credits ever expire?
Never. Buy credits when you need them and use them entirely at your own pace. There are no deadlines, no monthly resets and no pressure.
Why are my current AI results so mediocre?
Because vague inputs produce vague outputs. AI models are extraordinarily powerful, but they respond precisely to what they are given. A poorly structured prompt returns generic results. An engineering-grade prompt unlocks the full capability of the model.
Do I need an account to use Promptly?
No account required. Pay via Stripe, receive your credits instantly, and use them straight away. No sign-up, no passwords, no profile to manage.
Is my payment information stored?
No. All payments are processed securely by Stripe. Promptly never sees, stores or handles your card details at any point.
What makes Promptly different from just asking AI to improve my prompt?
Promptly uses a Claude-powered expert system specifically trained in prompt engineering for each medium. The output is not a general rewrite — it is a structured, role-assigned, format-defined prompt built to get maximum performance from whichever AI you use next.
Can I use Promptly for professional or commercial work?
Absolutely. Promptly is built for exactly this. Marketers, content creators, designers, developers and agencies use it to dramatically accelerate their AI workflows and raise the quality of every output.
What if the generated prompt does not give me what I wanted?
Use another credit to refine your input — add more detail, specify a style, or narrow the brief. The more precise your idea, the more targeted the prompt. Most users find the first result transforms their output immediately.
Why buy a larger credit pack?
Every tier is genuinely cheaper per credit. The £10 pack delivers 125 credits at 8p each — 20% cheaper than buying £1 at a time. If you use AI regularly, the larger packs pay for themselves quickly.
