## Tools (4)

- `compare_tools`: Two EffectHub tool cards side by side — pricing, scores, platforms, API, liveness — plus the differences in plain sentences. When EffectHub has a researched head-to-head page for the pair, comparison_url links to it.
- `get_tool`: Everything public on one EffectHub tool card: what it does, category, pricing model and entry price, Effect score, Trust score, platforms, whether it is still alive and when that was last checked, and the card URL. Takes the tool's slug (from search_tools, or the last part of https://effecthub.net/ai/{slug}).
- `list_alternatives`: Tools that do the same job as the given one. Alternatives our research named for this tool come first (basis "researched"), then live tools from the same category (basis "category"). Discontinued tools are left out.
- `search_tools`: Search the EffectHub catalog of AI tools by product name, job to be done ("transcribe interviews") or category ("video editing"). Optionally narrow by task slug, category slug or pricing model. Returns published, live tools with pricing, Effect score and a link to each card on effecthub.net.
