Telegram Text + Voice Conversational Agent
This workflow creates a voice-enabled conversational assistant that receives audio messages, transcribes them via Whisper, processes the text with an AI Agent enhanced by Perplexity, and replies directly in chat. It can search the web and respond naturally in real time through Telegram, Slack, or similar platforms.

How Latenode estimates time and cost
Latenode bills workflow runtime in CPU seconds. The first 10,000 CPU seconds are free each month, then usage follows pay-as-you-go CPU-second pricing. Plug-and-Play (PnP) AI nodes are billed separately—each PnP token is $1 USD, charged pay-as-you-go at vendor cost plus a small processing fee, with no API keys required.
