Create AI chatbots in minutes

Build AI powered chatbots based on your own content. Fully customizable. Add to your website or share with your team. Bring your own OpenAI API key to keep costs low.

Stop overpaying for messages

Other platforms limit your messages on each plan and charge a big plus on top of it, we don't. We charge you a small monthly fee to cover the cost of the infrastructure and you can send as many messages as you want.

* Based on our fixed monthly plan of $19 and the assumption that a message is 1000 tokens, the current cost of OpenAI's models and the listed competitors. Realistically for most use-cases it will be less, but we'd like to be on the safe side. Last Updated: February 5th 2024.
