What platforms does Specifys.ai support?

Specifys.ai is available on Web App.

What are the limitations of Specifys.ai?

The homepage shows no concrete pricing tiers, credit costs or limits on paid plans. Spec quality depends heavily on how thoroughly you answer the intake brief; thin answers likely produce generic documents. Market research is qualitative (SWOT, ICP, GTM) with no sizing or validation data, so it should not replace real research.

What is Specifys.ai?

Specifys.ai is an AI project builder tool that turns an app idea into a full PRD before AI writes code.

Specifys.ai is an AI planning workspace for software projects. Instead of jumping straight into a chat window and prompting an assistant to write code, you describe the app you want and receive a structured specification: application overview, user stories, acceptance criteria, technical architecture, database schema, API endpoints, market research, design direction and diagram definitions. The homepage frames this as the difference between twenty disconnected prompts and a single complete project document. The workflow is short by design. You answer a brief covering pages, features, audience, platform, age range, interests and constraints, and can attach reference screenshots for layout guidance (up to ten). The tool then generates a spec that opens in a Spec Viewer, organised into tabs for Overview, Technical, Market Research, Design, Diagrams and Prompts. The overview stage includes personas and epics; the technical stage carries architecture notes, a Postgres schema and endpoints; the design stage holds a colour palette, theme preview, component inventory and app icon direction. Diagrams are delivered as Mermaid, and the prompts tab produces IDE-ready development prompts split into build, review and test variants across ordered stages. It is aimed at founders, developers, product managers and agencies who want a shared reference before implementation starts. The pitch is that a written PRD reduces rework caused by vague chat context and invented architecture, and the site reports roughly 25 pages for a typical spec, about 4 minutes to first draft and 70% fewer prompt iterations. Where it differs from general coding assistants: those tools excel inside a single file or function, while Specifys.ai works one layer above and hands the plan to a person or an agent. Output can be exported for Cursor and Windsurf or connected through MCP so the IDE reads from the live spec. Pricing details beyond a free first spec and paid upgrades are not spelled out on the homepage.

How do you use Specifys.ai?

1Create a free account
Planning requires registration, which is used to save specifications, manage projects and track progress. The free account is enough for the first spec.
2Describe your app in the brief
Pick your role (founder, developer, product manager or agency) and fill in pages, features, audience, platform and constraints. Page and feature presets speed this up.
3Optionally add screenshot references
Upload up to ten UI screenshots with a short note when you want a specific layout. Each one is analysed and can be edited before you confirm it.
4Generate and review the spec
Run the generation and read the result in the Spec Viewer tabs: Overview, Technical, Market Research, Design, Diagrams and Prompts. Check personas, schema and endpoints against what you intended.
5Connect or export to your IDE
Either export a structured package for Cursor or Windsurf, or wire the spec into your IDE over MCP so the agent reads the live document as context.

Pros and cons

Pros

Produces a multi-stage document rather than a single chat answer, covering overview, technical, market, design, diagrams and promptsAI
Prompts tab splits work into ordered stages with build, review and test variants per stageAI
MCP bridge lets IDEs such as Cursor and Windsurf pull context from the live specAI
Screenshot references and feature presets let you steer layout without writing a long briefAI
Example spec library covers CRM, marketplace, booking, AI SaaS, social and support apps for comparison before generating your ownAI

Cons

The homepage shows no concrete pricing tiers, credit costs or limits on paid plansAI
Spec quality depends heavily on how thoroughly you answer the intake brief; thin answers likely produce generic documentsAI
Market research is qualitative (SWOT, ICP, GTM) with no sizing or validation data, so it should not replace real researchAI
Spec Viewer, editing and export flow are hard to judge without an account; pro editing is gated behind subscriptionAI
Only three public pages are linked, so documentation depth for MCP setup and troubleshooting is unclearAI
