How they differ
Second Nature has been building AI role play since 2018 and is known for its conversational avatars, which run in voice and video. It is used beyond sales, for customer support, call centers and HR training, and it slots into an existing learning stack: any LMS via SCORM or LTI, plus CRMs, SAML and conference tools. It supports more than 30 languages.
Muntri is narrower on use case and wider on the revenue side. Practice is built for sales calls, scored against a sales rubric, and you can start without a demo. If you need more than practice, the Enablement Platform adds content, learning paths and certification, and the full platform adds CRM, pipeline and customer success on one record.
