Without brief

build a website for my dog walking business

Vague. The AI guesses scope, features, and tech stack.

With brief

Build a website for my dog-walking business that serves dual purposes: (1) as a booking platform where clients can schedule and pay for dog-walking services, and (2) as a marketing and trust-building site to attract new customers and establish credibility.

See full prompt

The website should include:

  • A booking/scheduling system where clients can select dates, times, and service durations, and complete payments
  • Portfolio or gallery sections showcasing your dog-walking services (photos, testimonials, case studies)
  • Clear information about your services, pricing, and service areas
  • An about/bio section to build trust and demonstrate expertise
  • Customer testimonials or reviews prominently displayed
  • Contact information and inquiry forms
  • Mobile-responsive design since potential clients will likely browse on phones

Edge cases to consider:

  • Handle cancellations and rescheduling in the booking system
  • Ensure payment processing is secure
  • Accommodate different dog sizes, breeds, or special needs if applicable
  • Prevent double-booking of your time
  • Include clear terms of service and liability information

Specific. Covers features, edge cases, and asks the right questions before building.

Frequently asked questions

Does brief work with Cursor, Copilot, and Claude?

Yes. brief works with any AI tool. It rewrites your prompt before you send it, so it's completely tool-agnostic. Cursor, Copilot, Claude, ChatGPT, or anything else.

Is brief free?

brief is free to start with 20 rewrites per day. Paid plans with unlimited rewrites and additional features are coming soon.

What platforms does brief support?

brief is available as a desktop app for macOS and Windows. It runs as a lightweight menu bar / system tray app and works with any text input.

Is my data stored or sent anywhere?

Your prompts are sent to our API for rewriting and are not stored or logged. brief does not collect, train on, or share your data.

How is this different from just writing a better prompt myself?

brief's algorithm was trained on thousands of real developer prompts to identify the specific gaps that cause AI tools to produce generic or incorrect output. It fills those gaps automatically in under a second.

Can I customize how brief rewrites?

Yes. brief has 5 specialized modes, 7 built-in styles, and support for fully custom styles where you define tone, formality, and format. You can also add a context file for project-specific instructions.
