When to stay with Lindy.ai

While Lindy can handle phone calls through integrations, voice is one of many capabilities rather than its core focus.
- Far broader general-purpose automation — email, scheduling, data extraction, and multi-step workflows well beyond phone calls.
- Lower entry price ($49/mo) if voice is only one of many tasks you want a single AI assistant to handle.
- A better fit for teams that want one flexible AI agent platform across many workflows rather than a dedicated voice product.
