Hana AI

Hana AI has a free plan, with paid tiers at $7 and $15 per user per month. The free plan covers unlimited users and groups but caps each person at 20 interactions a month, so a busy team will hit the limit quickly.

Hana AI is an AI assistant for Google Chat that helps teams with productivity tasks and workflow automation inside the chat they already use.

The free plan runs on GPT-4o and GPT-4o mini, with access to the o3-mini reasoning model and chat history context of 10 minutes.

Basic costs $7 per user per month and raises the cap to 70 interactions and 15 minutes of context.

Pro costs $15 per user per month and switches to GPT-4.1 and GPT-4.1 mini, adds the o3 and o4-mini reasoning models, handles up to 1M tokens per request, removes the interaction limit, and extends context to 20 minutes.

Pro also adds extra actions and model use cases.

If your team wants a chatbot without leaving Google Chat, the tiers are easy to compare.
