AI voice agents, as AI assistants see them
In the week of 21 September 2026, the AI assistants we track most often recommend Retell AI (52), Vapi (44) and Bland (27) for ai voice agents, out of 29 products we follow in this category. Scores are the share of 60 answers naming each product, across 3 assistants.
Out of 29 AI voice agent products tracked, Retell AI leads with an overall score of 52 out of 100, named in 44 of 60 answers. Vapi trails close behind at 44, appearing in 38 of 60 answers, making the top of the leaderboard a genuine two-way race. After that, the gap widens: Bland sits at 27, ElevenLabs Agents at 26, and Synthflow rounds out the top five at 22. Scores vary by assistant too, Retell AI hits 68 with ChatGPT but only 48 with Perplexity, showing that "leading" depends a bit on who you ask.
Updated 2026-09-21. We re-ask every assistant on a schedule and publish whatever they say.
