whichtool.dev is a curated decision matrix built from five years of personal notes on 200+ apps and tools. Click a scenario like “I need to write code with AI help,” and get a recommendation with pros, cons, and an opinionated verdict.
I’ve tested over 200 tools for thought, AI apps, and productivity tools — a weird little hobby that produced a genuinely useful reference. The friction of remembering which tool fits which scenario is what turned the private notes into a public site.
Features
- Scenario-based filtering — start from what you’re trying to do, not from a product list
- Category browsing — 32 categories from AI Models to CLI Tools
- Full-text search — across names, descriptions, pros, and cons
- Cards and table views with platform badges (Web, Windows, macOS, iOS, Android, Linux)
- Active-use indicators — see which tools are currently in my own toolkit
Principles
Completely free and available to all. No subscriptions, no ads, no gated content. The data is subjective by design — every verdict comes from actually using the tool.
I wrote about the backstory in Which Tool?, the essay that launched it.
