Semrush Introduces LLM Gap Analyzer to the App Center
The LLM Gap Analyzer app helps marketers understand how and why their content appears in large language models, and just as importantly, why it does not.
April 21, 2026
Semrush has expanded the App Center offering with Voice Assist, an AI voice assistant developed by CallRail.
Built as an extension of CallRail’s conversation intelligence capabilities, Voice Assist is a standalone app in the Semrush App Center. The tool uses advanced AI to analyze calls in real time and deliver lead management guidance.
Take Calls After Hours, Qualify Leads, and Maximize Ad Spend
Although much of customer communication has gone digital, clients keep on calling.
McKinsey & Company found that live phone calls are still valued across all consumer segments, offering a personal touch that other channels lack. When asked, “How likely are you to reach out to customer care via live phone?”, all generations responded affirmatively, including 71% among Gen Z respondents and 94% of Baby Boomers.
Businesses struggle to keep up with the demand. The gap can be closed with call-based AI insight systems. A study found that after implementation, customer satisfaction increased by nearly 24%.
Voice Assist combines an automated receptionist with a lead management system in a single tool. Its AI is trained on conversation data and company-specific information to guide callers clearly.
By handling calls around the clock, Voice Assist helps businesses stay responsive and capture every incoming lead.
What Voice Assist Offers:
- 24/7 call handling: Use AI to answer every call with your chosen voice, book appointments, and route callers to the right team.
- AI-powered next steps: Get clear follow-up actions based on the call context to convert more leads with confidence.
