SaaS Pricing Tier Strategist
Design pricing tiers around who the customer is and what they value, with the metric you charge on and the upgrade trigger for each tier.
Act as a pricing strategist for software products. Design a pricing structure. The product: - What it does and for whom: [PRODUCT, AUDIENCE] - The value it creates, in the customer's terms: [TIME SAVED / REVENUE / RISK REDUCED — with a number if I have one] - Current pricing, if any: [TIERS AND PRICES] - Costs that scale with usage: [API CALLS, STORAGE, SUPPORT] - Competitors and their prices: [LIST] - Customer segments I actually serve: [e.g., solo users, small teams, agencies] - Where existing customers get stuck or churn: [WHAT I KNOW] Deliver: 1. The pricing metric — what we charge per — with two alternatives and the trade-off of each. Explain which one grows with the value the customer receives rather than with our costs 2. Three tiers, each with: who it is for, the price, what is included, and the single feature or limit that makes someone outgrow it 3. The upgrade trigger for each tier, stated as an event the customer will notice 4. What to deliberately leave out of the lowest tier, and what should never be paywalled because it blocks the first success 5. Free trial versus freemium for this product, with the reason 6. Annual discount, and whether it makes sense given my cash position 7. How to change prices for existing customers: who gets grandfathered, for how long, and the email that announces it Flag any recommendation that depends on data I have not given you.

Built into every resultVague prompt in, vague answer out
Most people type a one-line request, get a generic reply, then re-prompt again and again trying to fix it. The AI is capable — the instructions just aren't clear enough.
You re-prompt 5 times
Tweaking wording by hand until the answer is finally usable wastes more time than the task itself.
Bland, off-target replies
No role, no context, no format — so the model guesses, and you get something generic.
You don’t know the tricks
Prompt engineering has real techniques. Learning them for every model is a job on its own.
A clear prompt gets you there faster
Describe the goal once. PromptVibe adds the role, context, constraints, and output format a good answer needs — so you spend minutes, not an afternoon, and you don't have to learn prompt engineering to do it.
Better answers, fewer tries
Structured prompts give the model what it needs the first time.
No expertise required
Pick a framework or let Standard handle it — plain English is enough.
Works with your AI
Tune the prompt for ChatGPT, Claude, Gemini, Midjourney, and more.
Built on real prompt-engineering frameworks
PromptVibe doesn't rely on a black box. Every prompt is built from named, documented frameworks — ROLE, TAG, COAST, RISE, APE, RACE — so you can see exactly why it's structured the way it is, and learn the pattern as you go.

|---|---|---|
| Approach | Generates a custom prompt from your goal | Browse pre-made templates |

Prompt Generator vs Prompt Optimizer
Prompt Generator
Start from scratch. Describe your goal in plain language and the generator creates a structured prompt using your chosen framework. Best when you have an idea but need professional structure.
Example: "Create a weekly workout plan for building muscle" → structured ROLE-based prompt with fitness coach persona, program constraints, and output format.
Prompt Optimizer
Improve an existing prompt. Paste a weak or vague prompt and the optimizer rewrites it with added context, clear role definition, output format, and constraints.
Example: "write about AI" → "Act as a technology journalist with 10 years of experience. Write a 750-word explainer on practical AI applications for small businesses..."
Which Prompt Framework Should You Use?
Quick answer: use TAG for fast, simple requests, ROLE for complex tasks that need a defined persona and constraints, and COAST when the task needs full background context. The table below maps each framework to its best use case.
| Framework | Stands for | Best for |
|---|---|---|
| TAG | Task, Action, Goal | Quick, direct, single-step requests |
| ROLE | Role, Objective, Limitations, Expectations | Complex tasks needing a persona + constraints |
| COAST | Context, Objective, Actions, Scenario, Task | Tasks that need full background context |
| RISE | Role, Input, Steps, Execution | Multi-step workflows and processes |
| APE | Action, Purpose, Execution | Action-oriented, step-based tasks |
| RACE | Role, Action, Context, Explanation | Educational content and explanations |
| Standard | General purpose | Everyday prompts with no special structure |
Prompt Engineering FAQ
What is prompt optimization?
Prompt optimization means refining an input prompt so the AI model gets clear role, context, constraints, and output format instructions. A well-optimized prompt reduces ambiguity and produces more consistent results.
How do I generate prompts for free?
Use create mode to describe your goal, pick a framework such as ROLE or TAG, select a target AI model, and click generate. Your first prompt is shown in full with no signup; after that, enter your email once to unlock results and get a free pack of 50+ prompts. Write in any language and the prompt comes back in that language. No account or credit card needed.
Which AI models does PromptVibe support?
PromptVibe supports ChatGPT, Claude, Gemini, Grok, Perplexity, GLM, DeepSeek, Qwen, MiniMax, Kimi, Xiaomi, and Llama for text and code tasks; Midjourney, DALL-E, Stable Diffusion, and Nano Banana for image generation; and Sora, Veo, and Runway for video generation. PromptVibe is not affiliated with any of these AI model providers.
Does PromptVibe guarantee better AI results?
No. PromptVibe generates structured prompts based on proven frameworks, but it cannot guarantee the quality of AI output. Results depend on the AI model, your specific context, and how you apply the generated prompt. Always review AI-generated content before using it.
