Installation & First‑Time Setup

PromptFlow eliminates the traditional installation hurdle entirely. To begin, open a supported browser (Chrome, Edge, Firefox, or Safari) and navigate to promptflow.ai. The landing page greets you with a clean, minimalist dashboard that highlights both the “Search” and “Create” functionalities.

Signing up takes less than a minute—simply enter an email address, or connect via Google or Apple ID. After confirming your email (if you chose that method), you are instantly logged into your personal workspace. Because the service runs on remote servers, there is nothing to download, no system drivers to install, and no GPU requirements on your device.

This design makes PromptFlow ideal for students using school computers, freelancers on shared workstations, or anyone who prefers a lightweight, cloud‑first approach.

Step‑by‑Step Usage Guide

1. Enter a Prompt: Type a clear, descriptive sentence—e.g., “a futuristic city skyline at sunset, cyberpunk style.”
2. Select an AI Model: Choose the default model for balanced results, or pick a specialty model for stylized output (cartoon, photorealistic, watercolor, etc.).
3. Apply Filters: Use the sidebar to set resolution, aspect ratio, color scheme, or mood tags that narrow the AI’s focus.
4. Generate & Review: Click “Generate.” The platform returns a grid of thumbnails; select any to view a larger preview, then adjust sliders for creativity, detail, or lighting to fine‑tune the image.
5. Save or Export: Add the final image to your cloud library, download it in your chosen format, or copy a shareable link for collaboration.
6. Reuse & Iterate: Access your prompt history at any time, duplicate previous sessions, or modify a saved prompt to explore new variations without starting from scratch.

Compatibility Across Devices

Since PromptFlow is accessed through a web browser, it works on virtually any operating system that supports modern web standards. Officially supported environments include:

• Windows 10, 11 – Chrome, Edge, Firefox
• macOS Ventura, Monterey – Safari, Chrome, Firefox
• Linux distributions with up‑to‑date browsers (Chrome, Firefox)
• Android 9+ – Chrome, Firefox
• iOS 14+ – Safari, Chrome

Because the heavy AI processing happens on PromptFlow’s cloud infrastructure, your device’s CPU or GPU performance only affects the responsiveness of the user interface, not the speed of image generation. This means you can comfortably run PromptFlow on a budget laptop, a tablet, or even a smartphone without sacrificing output quality.
