Ask your AI assistant if Otis is right for you.

Paste this into your AI assistant

I’m thinking about using Otis (https://otisbase.com) for my client billing. Read https://otisbase.com/llms.txt and https://otisbase.com/how-it-works to learn what it does and what it doesn’t. If you can connect to MCP servers, try the read-only sample it describes. Then ask me a few short questions: what I bill for, how many clients I have, how I invoice today, and which AI assistant I use. Based on my answers, tell me honestly whether Otis would help me, what it would take over, and what it can’t do. If it’s a good fit, walk me through connecting it.

Good to know

  • What you pay for elsewhere

    Your AI assistant’s own subscription. No AI model runs on Otis, so there is nothing else to pay for.

  • Who covers the costs

    Startup support from Cloudflare, where Otis runs, and from Anthropic, the makers of Claude. Thank you to both.

  • If paid extras come later

    They’ll sit on top of Free. Nothing in Free goes away.
