The prompt

Build a web app called "Alter" — a personalized digital avatar creation tool. Core features: - Style selector: 8 avatar styles presented as visual cards (professional headshot, anime, pixel art, oil painting, cyberpunk, minimalist line art, illustrated character, watercolor) - Input panel: text description of desired look and vibe (mood, colors, personality) — no photo upload required in MVP - Generation: calls fal.ai FLUX API with a structured prompt built from the style selection and description — generates 4 variants per request - Customization: background color picker overlay, optional username/tagline text added via Canvas API - Download: PNG at 400px, 800px, and 1500px square - History: last 12 generated packs saved in localStorage — click any to view and re-download UI: bright, expressive, fun. Large visual cards for style selection. Results shown in a 2x2 grid. Mobile-responsive. Stack: React, fal.ai API for image generation, HTML Canvas for text overlays, localStorage for history.

How to use this prompt

Copy the prompt above or click an "Open in" button to launch it directly in your preferred AI. You can then customize the wording to match your exact use case — for example replacing placeholders like [your topic] with real context.

Which AI model works best

Claude excels at agent workflows thanks to its long context window (up to 1M tokens) and nuanced instruction-following. ChatGPT has native Actions (tool-calling) built in. Gemini integrates best with Google Workspace data. For autonomous workflows, Claude Sonnet 4.6 is the current sweet-spot for quality and cost.

How to customize this prompt

Adjust the agent's role and constraints to your environment. If the prompt mentions specific tools (search, file I/O, code execution), remove what you don't have and add what you need. Add guardrails: "Always ask for confirmation before writing files." Define success criteria explicitly.

Common use cases

Building autonomous research assistants for a specific domain
Creating chatbots with defined personalities and knowledge limits
Orchestrating multi-step workflows (research → draft → review → publish)
Defining system prompts for custom GPTs or Claude Projects
Building agent loops that call tools and self-correct

Variations

Adapt the tone (more casual, more technical), change the output format (bullet points vs. paragraphs), or add constraints (word limits, target audience).
