Our Agent Rank score currently lists 14 research agents — ranked by autonomy, capabilities, integrations and price-to-value. The shortlist on this page reflects our weekly editorial sweep; full methodology at /methodology.
AI research agents range from free open-source (self-hosted, BYO API key) up to enterprise tiers from $500/month per seat. Most teams that ship daily land between $20–$100/month per user. Click any card to see the full pricing tiers.
A tool waits for every click. An agent gets a goal and runs multiple steps autonomously — driving the browser, executing code, reading files, calling tools — until the goal is met. The list above is restricted to agents; pure tools live at /ai-tools.
Start with the top three by Agent Rank score (they balance all six scoring axes). If you have a specific integration or compliance need (HIPAA, GDPR, SSO), filter via the comparison page at /compare. For solo users, the cheapest paid tier is usually the right entry point.
