A prospect visits your site at midnight wanting to learn about your enterprise plan. Your AI Agent activates a Convolo AI character with deep product knowledge and a professional voice. The character walks the visitor through features, answers pricing questions, and captures their contact details. Your sales team gets a qualified lead brief by morning, complete with the full conversation transcript.
A new customer signs up from France and prefers speaking French. Your AI Agent creates a session with a French-configured Convolo AI character that guides them through account setup, explains billing terms, and answers initial questions. The customer completes onboarding in their native language. Your support queue stays clear of repetitive setup tickets.
Your team runs 500 voice conversations daily and needs quality oversight. After each session, your AI Agent calls the Evaluate Character endpoint with scoring criteria for empathy, accuracy, and resolution. Low-scoring sessions get flagged for human review. Your QA team focuses only on conversations that need attention instead of sampling randomly.

FAQs
The agent calls the List Voices endpoint to retrieve all available voice profiles, including different genders, accents, and languages. You select a voiceType identifier when creating or updating a character. Convolo AI supports voices across multiple locales, so your character can speak in American English, British English, French, German, and more.
The Knowledge Bank is a document repository that grounds your character's responses in factual content. Your Tars agent uploads PDFs, text files, or other documents via the Upload Knowledge Bank endpoint. During conversations, the character references this material to give accurate, domain-specific answers instead of generic AI responses. This feature requires an Enterprise plan.
Yes. The Get Character Response endpoint accepts either userText for typed messages or a mono WAV audio file for voice input. You can also enable voiceResponse to receive spoken replies. A single session can mix text and audio interactions seamlessly based on how your customer prefers to communicate.
In your Tars dashboard, navigate to Tools and select Convolo AI. Enter the API key from your Convolo AI developer settings. Once authenticated, the tool appears in your available integrations. Attach it to any AI Agent Gambit, and the agent can create characters, start sessions, and manage knowledge banks during conversations.
You define the evaluation criteria through a custom prompt that includes a [[conversation_history]] placeholder. The endpoint analyzes the session transcript against your prompt, scoring dimensions like clarity, helpfulness, tone, and resolution quality. You can also pass custom variables for additional context. Results help your QA team spot patterns without reviewing every conversation manually.
No. Audio data is streamed between your customer and the Convolo AI backend in real time. Tars passes the audio through the API call but does not retain copies. Session transcripts may be available through Convolo AI's own dashboard, but Tars does not maintain a separate audio archive.
Convolo AI's interface lets you manually create and test characters. Tars automates the entire lifecycle programmatically. Your AI agent can spin up new characters, update backstories, swap voices, upload knowledge, and evaluate sessions during live customer interactions, all without anyone logging into a dashboard. It turns manual character management into an automated pipeline.
You can update backstory, voice type, name, and language codes using the Update Character or Update Backstory endpoints at any time. However, changes take effect in new sessions. An active session continues with its original configuration. This lets you iterate on character behavior between conversation rounds without disrupting ongoing interactions.
Don't limit your AI Agent to basic conversations. Watch how to configure and add powerful tools making your agent smarter and more functional.
