Tough Tongue AI is a platform for building and deploying live voice AI agents. The company describes it as a way to practice high-stakes conversations with realistic AI partners, and also to automate conversations such as sales calls, demos, and candidate screening. For interview preparation, it offers AI mock interviews, including PM, coding, and system design rehearsal.
The product has two sides. One is training: sales coaching, negotiation, leadership development, K-12 teacher training, and job interview practice. The other is automation: an AI SDR, outbound calling, customer service agents, and hiring screens. The company says it is a research lab covering voice AI, cognitive science, and human performance, with a remote team in the US, India, and the Netherlands.
The site describes three steps: create an agent, deploy it, and analyze the sessions. Agents can be scaffolded from Claude Code, remixed from a template, or described in plain language. For sales teams, users can upload recordings of calls, pitch decks, and battle cards, describe the buyer, and let the platform build a scenario that can be shared by link, iframe, or an enterprise account.
Agents deploy on phone calls, Google Meet, Zoom, and the web. During a session they can show slides, images, multiple-choice questions, whiteboards, and code editors. The company says they read tone and facial expressions, remember progress across sessions, and answer in under a second. Afterward each session is scored and logged, so users can review feedback and teams can track results.
The scenario library covers cold calls, discovery, objection handling, demos, and enterprise deal roleplay, each with a buyer persona that has its own personality and pushback style. Scenario Studio lets teams build their own from real material. Feedback is described as concept-based rather than keyword-based, so reps can answer in their own words instead of reciting scripts.
On the automation side, the AI SDR demos a product with slides and screen sharing, qualifies leads, handles objections, and books meetings. Outbound calls can be triggered from a CRM. An organization dashboard tracks rep progress over time and exports CSV data. Through an MCP option, teams can also start calls and coaching reviews from Claude, Codex, or Cursor.
Tough Tongue AI is a platform for building live voice AI agents. Teams use it for roleplay practice in sales, leadership, and job interviews, and for automating calls, demos, and candidate screening. Agents run on phone, Google Meet, Zoom, or the web.
