What it can do
| Tool | What it says it does |
|---|---|
company_stack | Tools a company publicly uses according to usedby, strongest proof first, each with its proof level (job-post signals last) and source page. Each `listed` line carries its `proof` level, strongest first: quote the per-level `mix` next to any total. A line whose source.method is SUBPROCESSOR_LIST… |
compare | Two tools side by side: public customers with their proof mix, top industries, the companies on both (every proof level, each side's level given), and vendor facts with their sources.

who_uses | Companies that publicly use a tool, strongest proof first, each with its proof level (CONFIRMED, DECLARED: the company states it, OBSERVED, or SIGNAL: a job post, the weakest proof), source page and first public proof date. Each `listed` line carries its `proof` level, strongest first: quote the… |
