ailoopour toolfree · bring your own key
Design a loop in minutes — objective, metric, boundary — then it writes, an independent model judges, and it keeps the winners.
Best for turning a fuzzy ‘make it good’ task into a measurable, repeatable loopSkip if you just need a single one-off answer (use a chat model)

Claude Code$$ subscription / usage
Agentic CLI that edits files and runs commands across a whole repo — delegation, not autocomplete.
Best for multi-file changes, refactors, ‘go do this task’Skip if you only want inline single-line suggestions
AI-native editor with strong in-editor chat and edits that understand your repo.
Best for staying in a familiar VS Code-style editorSkip if you live in the terminal

Best for sentiment, classification, pulling fields from prose at volumeSkip if you need pixel-perfect tables out of scanned PDFs (use a dedicated OCR/doc tool)

General reasoning, writing and chat

They trade the lead constantly — the honest move is to run your real task on two of them. We keep a dated comparison.
