I-Onlabs AI Tool Picker
Quick reference for vibecoders juggling multiple AI tools.
Decision Tree
What are you trying to do?
Writing/Editing Code in a File
→ Cursor or Windsurf (in-editor, sees your files) → Claude Code (terminal-based, good for refactors across many files)
Quick Question or Concept
→ Grok (fast, real-time info) → This Claude (if you're already here) → ChatGPT (familiar, broad knowledge)
Long Codebase or Big Context
→ Gemini (huge context window — 1M+ tokens) → Claude Code (can navigate and read files itself)
Creating Files, Docs, Diagrams, Presentations
→ This Claude (creates downloadable files, artifacts, browser control)
Debugging Error Messages
→ Paste into Cursor/Windsurf (sees your code) → Or paste into This Claude with the file
Agentic Tasks (multi-step, autonomous)
→ Claude Code (runs commands, edits files, loops until done) → Codex CLI (OpenAI's agent) → Aider (open source, git-aware)
Research + Code
→ This Claude (web search + file creation) → Gemini (good at research, massive context) → Perplexity (research-first, then code)
Image Generation / Vision
→ ChatGPT/DALL-E (image generation) → Claude (vision analysis, can see images) → Gemini (vision + generation)
Tool Profiles
| Tool | Best For | Limitations |
|---|---|---|
| Cursor | In-editor coding, tab completion, inline edits | Needs IDE open, per-file focus |
| Windsurf | Similar to Cursor, Cascade flow | Same as Cursor |
| Claude Code | Terminal agent, multi-file refactors, autonomous | Command line only |
| This Claude | Files, research, browser control, conversations | Not in your IDE |
| Gemini | Huge context (2M tokens), research | Can be verbose |
| Grok | Fast answers, real-time X/Twitter data | Less depth |
| ChatGPT/GPT-4 | Familiarity, DALL-E, plugins | Rate limits |
| Codex CLI | OpenAI's terminal agent | Newer, less mature |
| Qwen | Free/open, good at code | Less polish |
| Aider | Open source, git-integrated | Setup required |
| Copilot | VSCode integration, autocomplete | Less agentic |
Common Scenarios
"I need to refactor authentication across 20 files" → Claude Code — it can navigate, plan, and execute
"Help me understand this error in my React component" → Cursor/Windsurf — sees your code context
"Create a presentation about my project" → This Claude — makes PowerPoint files
"What's the best way to structure a Next.js app?" → Any of them, but Gemini/Claude for long explanations
"I'm stuck and don't know what's wrong" → Start with Cursor (sees your files), escalate to Claude Code if complex
"Build me a landing page from scratch" → Cursor/Windsurf for iterative coding, or This Claude for a complete artifact
"Analyze this 500-page PDF" → Gemini (massive context) or This Claude (can read PDFs)
"What's happening in the news about X?" → Grok (real-time) or This Claude (web search)
"Generate an image for my app" → ChatGPT/DALL-E, Midjourney, or dedicated image tools
Pro Tips
- Stay in one tool per task — context switching loses context
- Cursor/Windsurf for flow — stay in editor, stay in zone
- Claude Code for big jobs — let it run while you do other things
- This Claude for output — when you need actual files to download
- Gemini for massive context — paste entire repos
- Match the tool to the output — need a file? Use something that makes files
- Use MCP servers — extend Claude Code with custom tools
Model Selection Within Tools
When you can choose the model:
| Task | Best Model |
|---|---|
| Complex reasoning | Claude Opus, GPT-4, Gemini Pro |
| Fast iteration | Claude Sonnet, GPT-4o-mini |
| Long context | Gemini 1.5 Pro (2M tokens) |
| Cost-sensitive | Claude Haiku, GPT-4o-mini |
| Code generation | Claude Sonnet, GPT-4 |
When Tools Hit Limits
| Problem | Solution |
|---|---|
| Cursor slowing down | Break into smaller files/tasks |
| Claude Code looping | Be more specific, or take over manually |
| Context too long | Summarize, or switch to Gemini |
| Rate limited | Switch tools temporarily |
| AI hallucinates | Ask for sources, or verify with another AI |
| Need real-time data | Use Grok or Claude with web search |
| Tool doesn't support feature | Chain tools — generate in one, edit in another |
Tool Combos That Work Well
- Research → Implement: This Claude (research + plan) → Cursor (code it)
- Prototype → Polish: This Claude (quick artifact) → Cursor (refine)
- Debug → Fix: Paste error in Claude → Apply fix in Cursor
- Big Refactor: Claude Code (autonomous) → Cursor (review/tweak)
- Learn → Build: Gemini (explain concepts) → Cursor (practice)
