PromptKit
PromptKit is a web application that turns a project description and a guided questionnaire into structured markdown documentation (PRD, tech stack, app flow, system prompts) giving AI coding assistants like Cursor, Copilot or Claude stable project context.
What is PromptKit?
PromptKit is a web platform that generates project documentation written to be read by AI coding assistants. Its premise, set out in the homepage section Help AI Better Understand Your Project, is that without clear documentation an assistant produces incorrect or off-target code, forces the developer to re-explain context, and suggests code that does not match the project's architecture. The answer it proposes is a structured document set those tools can parse.The path has three steps. Describe your project, its vision and goals, the site noting that more detail yields better documentation. Complete a questionnaire on architecture, technical stack and development practices. Create the documentation, which produces the requirements document, technical specifications and optimised prompts. Seven document types are named on the homepage: Project Requirements Document, Frontend Guidelines, Backend Structure Doc, App Flow Doc, Tech Stack Doc, File Structure Doc and System Prompts Doc. Output is markdown, which the FAQ says any AI assistant able to read markdown files can consume.Advertised compatibility covers Cursor, GitHub Copilot, Claude, Windsurf, Codeium, v0, Bolt, Replit and Lovable, with ChatGPT added in the FAQ. Hero badges announce GPT-5 Powered, Instant Generation and 30+ Templates. The positioning is deliberately indie, with 30+ indie-friendly project ideas for personal projects, side hustles and small-team development, and it is also pitched at people without coding experience, the questionnaire acting as the guided path.Two tiers exist: a free plan limited to one basic requirements document per project, and Pro, which unlocks every document type. Access runs through a dashboard, with a claimed two-minute setup and no installation.Several homepage figures are self-declared and carry no method or source: 25+ hours saved per project, 4M+ tokens saved, 87% fewer hallucinations, and a 4.8/5 rating over 127 reviews that appears only in the page's structured data. The publisher is a solo project with no company and no postal address, the official contact being ethan@ethanyu.me. The terms state a 99.9% uptime target, maintenance announced 24 hours ahead and support by email. A blog sits in the navigation but holds no articles.

When to use PromptKit / When not to
A quick filter to help you decide if PromptKit is the right fit.
When to use PromptKit
- Developers who work daily with an AI coding assistant and want to hand it stable, written project context instead of re-explaining the codebase in every session
- Indie makers and side-project builders, the audience the site targets with its library of 30+ indie-friendly project ideas for personal projects, side hustles and small-team development
- Teams opening a new web app, mobile app, browser extension or plugin and documenting it from scratch, since the flow starts from a blank project rather than an existing repository
- Non-technical founders and product people, as the guided questionnaire is designed to work from a basic concept with no coding experience required
- Users who move between several AI tools, because the output is plain markdown readable by any assistant that can open markdown files
When not to use PromptKit
- Anyone looking for a code generator: PromptKit produces documentation only and never writes the application itself
- Developers who need to call the service programmatically, as there is no public API and no API documentation for PromptKit itself
- Mobile, desktop or IDE-plugin users, since the product exists only as a web application with no app and no browser extension
- Buyers under procurement or audit constraints: no GDPR claim, no data processing agreement, no named subprocessors and no stated hosting country are published
- Organisations needing enterprise features or a signed contract, with only Free and Pro tiers, no team plan, no SSO and no legal entity or postal address published
How to use PromptKit
A typical end-to-end flow, from setup to results.
- Open the site and start from the free tier, which the terms confirm requires no credit card
- Create an account and reach the dashboard, where projects are handled
- Describe the project, its vision and its goals, in as much detail as possible, since the site states that detail drives the quality of the output
- Complete the questionnaire on architecture, technical stack and development practices
- Launch the generation and let the platform produce the documents and the optimised prompts
- Review the result: a basic requirements document on the free plan, all document types on Pro
- Retrieve the markdown files and place them inside the project so they sit alongside the code
- Point the AI coding assistant at those files, whether Cursor, GitHub Copilot, Claude, ChatGPT, Windsurf, Codeium, v0, Bolt, Replit or Lovable
- Browse the 30+ indie-friendly project ideas library when starting a project from scratch
- Upgrade to Pro when one requirements document is no longer enough; the site describes the upgrade as seamless, with premium features flagged in the interface
Pros & Cons
Pros
- Narrow, clearly framed scope: one problem only, the project context that AI coding assistants lack
- Output tied to no IDE, since plain markdown is readable by Cursor, GitHub Copilot, Claude, ChatGPT, Windsurf, Codeium, v0, Bolt, Replit and Lovable
- Permanent free plan with no credit card, giving one basic requirements document per project
- Public and low Pro pricing, USD 19 per month or USD 159 per year, with no quote to request
- Ownership of the generated documentation explicitly granted to the user, in the terms and again in the FAQ
- No installation and a setup the site describes as two minutes, with a guided questionnaire that opens the tool to non-technical profiles
- Stated service commitments: a 99.9% uptime target, maintenance announced 24 hours in advance, and a 30+ project ideas library on top of the documentation itself
Cons
- No legal entity and no postal address published anywhere, which makes the publisher impossible to identify
- Legal and support questions routed to ethan@ethanyu.me, a personal domain separate from the product, while the FAQ's Email us link still carries a mailto:your@email.com development placeholder
- Terms and privacy policy dated January 2024, earlier than the site's first Wayback capture on 17 January 2025
- No GDPR mention, no data processing agreement, no Article 27 representative, no retention period, no hosting country and no named subprocessors
- Internal contradiction on data: the FAQ states project details are never stored, while the terms describe stored metadata and aggregated, anonymised reuse to improve the models, with no training opt-out offered
- Performance claims, 25+ hours saved, 4M+ tokens, 87% fewer hallucinations, and the 4.8/5 rating over 127 reviews are self-declared and cannot be verified
- No public API, no mobile or desktop application, no browser extension, no team or enterprise plan, no SSO, no interface language other than English, no official social account, and a blog listed in the navigation that holds no articles

Data, GDPR & hosting
A consolidated view of how PromptKit handles your data.
GDPR overview
The site never uses the words GDPR or General Data Protection Regulation, on any page, so compliance is neither claimed nor denied. There is no EU representative under Article 27, no named data protection officer, no data processing agreement, no legal basis cited for any processing and no retention period. Third parties are described only by category, namely AI coding assistant services, payment processors and cloud service providers, and none is named; no hosting country or region is stated. The privacy policy does list rights that resemble GDPR rights: access and export of project data, deletion of the account and associated data, opt-out of non-essential data collection, and correction of personal information, with privacy@promptkit.tools as the contact. Both legal documents carry the notice Last Updated: January 2024. EU buyers should treat this as an informal framework rather than a documented one.
Who owns the data?
Section 3 of the terms states that users keep full ownership of their project information, their code and the documentation PromptKit generates. That documentation may be used across the user's own organisation and development tools, and the FAQ repeats that it can be freely used, modified and shared. Ownership of the service stays with the publisher: the AI models, algorithms and documentation templates remain its property, and reselling or redistributing those templates and optimisation techniques is prohibited. No corporate entity is named anywhere on the site, so the counterparty holding those rights is identified only by the PromptKit name and the contact address ethan@ethanyu.me, on a third-party domain.
Reuse rights
Generated documentation can be reused without asking permission: the terms allow it to be used inside the user's organisation and development tools, and the FAQ adds that it can be modified and shared at will. The only restriction is on PromptKit's own material, since reselling or redistributing its templates and optimisation techniques is forbidden. On the publisher's side, the privacy policy lists account data (name, email, professional details), authentication data, usage data and billing data, plus project metadata and structure, documentation templates and content, integration settings and preferences. Stated purposes are generating and optimising documentation, improving AI model performance and documentation templates, improving the platform, technical support, and handling payments and subscriptions. Data is shared with the AI coding assistant services the user selects, with payment processors and with cloud providers; the policy states that personal data and project information are never sold. One tension inside the site deserves attention and is not resolved by the site itself: the FAQ says project details are never stored once documentation has been created, while the terms describe storing essential project metadata and using aggregated, anonymised data to improve the AI models and templates. No opt-out from that reuse is documented; the only opt-out offered covers non-essential data collection.
Data retention & training
Hosting summary
The site states no hosting country and no hosting region. The privacy policy mentions the use of cloud service providers for infrastructure support without naming any of them, and the terms add that documentation is processed in isolated environments, with encryption during processing and transmission. No jurisdiction, no data centre location, no transfer mechanism and no data processing agreement are described. As a purely technical observation, and not as a commitment made by the publisher, the domain resolves to 76.76.21.21, an anycast front-end address geolocated in the United States on AS16509 (Amazon.com Inc.). That indicates where the entry point answers, not where project data is stored or processed. Anyone with a hosting-location requirement will need a written answer from the publisher, at privacy@promptkit.tools, before relying on the service.
Things to keep in mind
Risks and trade-offs to weigh before adopting PromptKit.
- The publisher cannot be identified: no company, no postal address and no legal notice, with legal and support contact sent to ethan@ethanyu.me, a domain unrelated to the product
- The Email us link in the site's FAQ points to mailto:your@email.com, a development placeholder left in production, so that support route reaches nobody
- Terms and privacy policy are dated January 2024, earlier than the site's first Wayback capture on 17 January 2025, so the published documents may not describe the service as it runs today
- The site contradicts itself on project data: never stored according to the FAQ, stored as essential metadata and reused in aggregated, anonymised form to improve the models according to the terms, with no opt-out from that reuse
- Metrics and social proof are self-declared: 25+ hours saved, 4M+ tokens and 87% fewer hallucinations come with no method or source, and the 4.8/5 rating over 127 reviews with named testimonials exists only in the page's structured data, behind no review page
- Promotional pressure without dates or conditions: a 50% OFF banner, strike-through prices of USD 38 and USD 456, and an Only 7 early-bird spots left scarcity message
- Documentation produced from a short description and a questionnaire is not reviewed by anyone, so treating it as the project's source of truth can quietly replace the team's own design work; the product is also a version 1.0.0 run by a single person, which concentrates continuity risk
Setup & Integrations
Technical difficulty
Very low. PromptKit is a web application: nothing to install, no IDE to configure, no API key to supply and no integration to authorise. The site advertises instant access and a two-minute setup, and the guided questionnaire is designed so that no coding skill is required. The sequence is create an account, describe the project, answer the questionnaire, generate. The only technical gesture left to the user is placing the generated markdown files inside the project so the AI coding assistant reads them, which supposes knowing where that assistant looks for context files.

Should you pick PromptKit?
PromptKit does one thing and frames it clearly: it writes the project context that AI coding assistants lack. The three-step path, describe the project, answer a questionnaire, generate the documents, produces markdown files tied to no particular IDE, which is the product's strongest structural choice. The same documents feed Cursor, GitHub Copilot, Claude, ChatGPT or any assistant that reads markdown, so the output survives a change of tool. Pricing is public and low, the free tier is a permanent plan rather than a trial, and the terms grant the user full ownership of what is generated.The other side of the file is thinner. No legal entity, no postal address and no legal notice are published; legal and support questions go to an email address on a personal third-party domain, and the FAQ contact link still carries a development placeholder. Both legal documents are dated January 2024, which predates the site's first archive capture in January 2025. The GDPR is never mentioned, no data processing agreement is offered, no subprocessor is named and no hosting country is stated. The FAQ says project details are never stored, while the terms describe stored metadata and aggregated, anonymised reuse to improve the models, with no way to opt out. The headline figures, 25+ hours saved, 4M+ tokens, 87% fewer hallucinations, and the 4.8/5 rating over 127 reviews, are self-declared and rest on no published review page.The reasonable reading is a well-scoped tool from a solo publisher, priced for individuals. For a developer, an indie maker or a small team wanting cleaner assistant output for the cost of a monthly subscription, the exposure is limited to that subscription. For a purchase subject to procurement, audit or data-protection review, the file is not complete enough to sign.
