How we researched and ranked AI support agents
Last updated: November 9, 2026
What we looked at
We included products whose main job is to resolve customer support conversations on their own, as opposed to tools that only draft replies for human agents. We started from widely used help desk platforms with built-in agents (Intercom, Zendesk, Salesforce, HubSpot, Freshworks, Gorgias, Kustomer) and from AI-first specialists that sell to support organizations (Sierra, Decagon, Ada, Forethought).
How we sourced facts
Every product fact comes from public sources read in November 2026. In order of preference: the vendor's official product and pricing pages, its official documentation and help centers, its press releases, and, where those weren't available, reputable third-party documents. Ada's website blocked automated reading, so Ada details come from its official documentation and press release plus a 2026 Bessemer Venture Partners case study. Ada's reported AWS Marketplace prices come from a review written by a competitor (Quiq); we could not verify them, and we label them that way wherever they appear. The ranking and pricing pages each end with a Sources list, and the full list is below.
Ranking criteria
- Breadth of fit: how many kinds of support teams the product serves well.
- Capability: channels covered, ability to take actions in other systems, handoff to humans, and testing and oversight tools, all as documented by the vendor.
- Accessibility: whether you can start self-serve or need an enterprise sales process.
- Pricing transparency: whether pricing is public, and how clearly the billable unit is defined.
Products that are strongest in one ecosystem (Salesforce, HubSpot, Shopify) are ranked by how broadly useful they are. Their best-for label tells you when one should be your first choice regardless of its position.
What we did not do
- We did not test any product hands-on, run benchmarks or measure resolution rates.
- We did not interview customers or publish reviews.
- Performance figures that vendors publish are vendor-reported. We present them as such, or leave them out.
- We don't accept payment for placement, and no vendor reviewed this ranking.
Updates
Pricing and products in this category change often. We re-check official pages when updating the guide and show the date of the last review on each page. If something is out of date, please check the vendor's own page, which takes precedence over ours.
