Who It's For

If you build with AI,
this was made for you

Four types of builders. One tool. All of them ship faster.

Primary
🎨

Vibe Coders

"I have the idea, AI does the coding — I just need the right prompt"

You use Cursor, Bolt, Lovable or Claude to build apps with AI. Vague prompts give vague results. PromptlyApps structures your entire idea so the AI actually understands it.

No prompt engineering knowledge needed
AI brainstorm extracts your idea for you
One-click auto-fill the entire wizard (Pro+)
Paste the result directly into Cursor or Bolt
👩‍💻

Developers

"I know how to code — I just want to describe architecture faster"

Writing detailed prompts with full stack, schema, RLS policies and file structure takes 30+ minutes. PromptlyApps does it in under 5 with AI suggestions at every step.

AI suggests optimal tech stack for your app
Auto-generates ERD and database schema
Includes auth, RLS and API route specs
Version history — fork and compare prompts
🧪

Testers & QA

"I need test plans that reflect the real app being built"

With the full blueprint and user flows from PromptlyApps, QA teams generate test scenarios, edge cases and acceptance criteria directly from the structured spec.

User journey maps every testable flow
Feature list drives acceptance criteria
DB schema reveals data edge cases
Export spec to share with your whole team
🚀

Deployers & DevOps

"I need to know what this app needs before I provision anything"

The Golden Prompt includes a full deployment checklist — env vars, Supabase setup, Vercel config and every integration. No more back-and-forth with developers.

Complete .env.example in every prompt
Supabase + Vercel deployment steps
Integration checklist (Stripe, Auth, Storage)
Infrastructure known before a line is written
🎯 For Vibe Coders

You describe it.
AI builds it.
PromptlyApps perfects the handoff.

Vibe coding is powerful — but vague prompts give vague results. The gap between "I have an idea" and "the AI understood it perfectly" is exactly where PromptlyApps lives.

Run through our 5-minute wizard and get a structured prompt with exact tech stack, database schema, user flows and design specs — then paste into Cursor, Bolt, or Lovable.

Builders love it

From first-time vibe coders to senior engineers.

"I used to spend 30 minutes writing prompts before every Cursor session. Now I describe my idea, hit auto-fill, and I'm coding in 3 minutes. The AI even picks the right database schema."

"The ERD generator alone saved me hours on my last project. I described my tables, it generated the full Mermaid diagram with relationships, and I just dropped it into my prompt."

"I'm not technical at all. PromptlyApps is the first tool that made me feel like I understand what I'm building. I described my food delivery app and it explained every technical choice in plain English."

"The DB Optimizer caught two missing indexes and a broken RLS policy in my schema that would've caused production issues. The SQL fix was copy-paste ready. Worth every penny."

Frequently asked questions

What is a "Golden Prompt"?+

A Golden Prompt is a structured, production-ready prompt you paste into any AI coding tool. It includes your full tech stack, database schema, component structure, API routes, auth setup and deployment checklist — everything an AI needs to scaffold your entire app correctly the first time.

Do I need to know how to code?+

No. PromptlyApps is built specifically for vibe coders who use AI to build apps without deep technical knowledge. The wizard explains every choice in plain English, and the AI brainstorm extracts your idea through conversation.

Which AI tools does the output work with?+

The generated prompt works with any frontier AI model or coding tool: Cursor, Bolt, Lovable, Claude, ChatGPT, GitHub Copilot, Gemini, Grok and more. It's plain text — paste it anywhere.

What is the Unified Agent?+

The Unified Agent is a single, powerful tool in your dashboard. You pick any saved prompt from your history, choose what you want to change (UI/UX, Database, Security, Add Features, Tech Stack, Architecture, or a Full Project Update), and the agent reads your entire wizard context — blueprint, architecture, data model and design system — then generates one comprehensive, ready-to-paste prompt you can use in any AI tool to modify your existing project.

What change types does the Unified Agent support?+

UI/UX Enhancement, Database Optimization, Tech Stack Change, Add New Features, Improve Security & Performance, Refactor Architecture, Full Project Update, and Other (custom description). Tech Stack, Architecture and Full Update require a Pro plan.

What is the Auto-fill wizard?+

Pro and Team users click one button after the brainstorm step and have all 5 wizard phases filled automatically by AI in about 15 seconds. It costs 15 credits and is the fastest path from idea to Golden Prompt.

How does the Unified Agent use my project context?+

When you run the Unified Agent, it automatically loads your entire project spec — app name, description, target users, MVP features, tech stack, database entities, ERD schema, design system and your existing golden prompt. The agent uses all of this to generate improvements that are specific to your actual project, not generic advice.

Can I save the Unified Agent output as a new version?+

Yes. Before generating, check the "Save as new version" option and the output will be saved to your prompt version history automatically. You can access it later from My Prompts in your dashboard.

What does the DB Optimizer sidebar tool do?+

The DB Optimizer sidebar tool scores your schema 0–100 and flags missing indexes, RLS policy gaps and N+1 query patterns — with copy-paste SQL fixes for each issue found. 8 credits.

Can I cancel my plan anytime?+

Yes — no contracts, no lock-in. Cancel from your dashboard at any time and you retain access until the end of your billing period.

Do new subscribers get a bonus?+

Yes — every first-time Pro or Team subscriber receives 50 bonus credits as a welcome gift. The bonus is credited automatically when your subscription activates.

How do credits work?+

Every AI action costs credits: brainstorm costs 1, blueprint suggestions cost 2, prompt generation costs 5, auto-fill costs 15, ERD Generator costs 15, Architecture Diagram costs 12, Unified Agent costs 12. Regenerating a diagram adds +5 credits. Credits reset monthly on your billing date.

How does the Team feature work?+

On a Pro or Team plan, you can create a team from the Teams section in your dashboard. Invite members by email — they receive a magic link to join instantly. All team members share your plan credit pool and can create, view and edit prompts in the team workspace. You can assign Owner, Admin or Member roles.

Do team members need their own subscription?+

No. The team owner subscribes to Pro or Team plan and all invited members share that plan credit pool. Members can use all features available on the owner plan without paying separately.

Can I use PromptlyApps without a team?+

Yes — individual accounts are fully functional. Teams are an optional layer for collaboration. Your personal prompts, credits and wizard are entirely separate from any team workspace.

What are the ERD and Architecture diagram generators?+

Two AI-powered diagram tools in your dashboard. The ERD Generator takes your app description and produces a complete Entity-Relationship Diagram (tables, fields, relationships) in Mermaid.js format. The Architecture Generator creates a high-level system diagram showing your frontend, backend, databases and integrations. Both render in the browser and can be downloaded as Mermaid code (.mmd) or PNG images.

What format are the diagram downloads?+

.mmd (Mermaid code) can be pasted into GitHub, Notion, Confluence, GitLab, or any Mermaid-compatible tool. PNG is a 2× retina-quality image ready for presentations, README files, or documentation.
