AI Tools Comparison
A quick-reference guide to the AI assistants and bonus tools you can use while building. All have free tiers.
Your Workspace: Replit (Already Decided)
The course uses Replit as your single building tool. Replit has a built-in AI assistant, code editor, live preview, and one-click deployment — all in your browser. You set this up in Lesson 3.3. You don't need to compare workspaces; we picked the one that works for every track. Stick with Replit through Module 7.
AI Assistants (Pick One, Outside Your Workspace)
Sometimes you'll want a separate AI assistant to plan, brainstorm, write project content, or talk through tricky decisions — separate from the AI built into Replit. Any of the four below works. They're all free.
| Tool | Strengths | Best For | Sign-Up |
|---|---|---|---|
| ChatGPT (chat.openai.com) | Strong code generation, wide knowledge, image generation built in. | General-purpose AI work. Good if you want code and images in one place. | Free, email or Google. 13+. |
| Claude (claude.ai) | Excellent at long, careful explanations and reasoning through complex problems. | Project planning, debugging tricky issues, writing thoughtful content. | Free, email or Google. 13+. |
| Google Gemini (gemini.google.com) | Tied into Google services (Sheets, Docs, Drive). Multimodal. | Students already deep in the Google ecosystem. | Free with Google account. 13+. |
| Microsoft Copilot (copilot.microsoft.com) | Built into Windows and Edge browser; good for quick research. | Students on a Microsoft device or already using Microsoft tools. | Free with Microsoft account. 13+. |
Which one should you pick?
Any of them. The prompting techniques you learn in Module 2 work for all four — that's the whole point. Pick one, stick with it for the course, and try a different one later if you're curious. If you have no preference, ChatGPT or Claude both have generous free tiers and work well for everything in this course.
Account setup note: All of these are 13+ and most ask for a parent's email confirmation when you sign up. Get a parent for the first signup.
Bonus Tools (Optional, Add as Your Project Grows)
You don't need any of these to finish the course. But once your project is working, these can level it up. Pick the ones that match what you're building.
| Category | What It Does | When You'd Use It |
|---|---|---|
| Image generation | Creates images from text descriptions (DALL-E built into ChatGPT, Midjourney, etc.) | Hero images, icons, illustrations, placeholder art for a portfolio. Always check the tool's usage rights. |
| Chart.js | A JavaScript chart library. AI loads it into your project for you. | Track 3 dashboards, or any project that needs charts or data visualization. |
| AI writing tools | Generate and refine text content — bios, descriptions, copy, etc. | Track 2 portfolios, About pages, anywhere you need a polished paragraph. |
| Design AI | Color palettes, font pairings, background removal, layout suggestions. | Visual polish. Or just ask your AI assistant for color and font recommendations. |
| Google Sheets | Organize data, write formulas, use as a simple database. | Track 3 data projects. Also useful for planning and content organization in any track. |
| Automation tools | Connect apps: "when X happens, do Y" (Zapier, Make). | Advanced/future projects. Not needed for this course. |
The Essential Toolkit
Everything you truly need to finish this course: Replit (your workspace) and one AI assistant (ChatGPT, Claude, Gemini, or Copilot). Everything else is bonus you can add as your project grows.
More tools means more complexity. Before adding a new tool, ask: "Can I do this with a tool I already have?" If yes, skip it.
