How we classify AI products
- Autonomous agent Completes multi-step tasks with tools and limited supervision, as documented by the vendor.
- Agentic tool A human-directed tool that can plan, edit and run actions, with the user reviewing or approving changes.
- AI assistant Answers questions and suggests content or code; the user performs the actions.
- Software with AI features Conventional software that includes AI features rather than being built around an agent.
We use a stronger label only when vendor documentation supports it.

Evidence first, with unknowns labelled.
Sourced and dated
Pricing, features and integrations come from vendor pages and documentation where possible, with the source and the date it was accessed shown on each profile.
Honest about gaps
When something is not documented in the sources we reviewed, the profile says so. We do not infer security certifications, autonomy levels or model capabilities.
No paid placement
This directory contains no paid placements, affiliate links, ratings or reviews. External links to vendor sites are labelled.
