IntoCal: Scheduling infrastructure for people, websites and AI agents.

IntoCal is meeting scheduling software for people and teams on Google Calendar or Microsoft Outlook, with booking pages, team routing, a developer API, and a hosted MCP server that lets AI assistants book meetings for you. Connect the calendars you already use, set your availability, and share one branded booking page, or embed it on your website. IntoCal checks live busy times, writes confirmed meetings back to your calendar, and adds a Microsoft Teams, Zoom, or IntoCal Meet link automatically. Confirmations, reminders, and reschedule links go out on their own. For teams, route meetings round-robin, book several hosts together, or let guests choose who they meet. What sets IntoCal apart: every user gets a hosted MCP endpoint. Claude, ChatGPT, Cursor, Windsurf, and Warp can check your real availability and request bookings natively, with nothing to install or maintain. Developers can also build on the REST API, TypeScript SDK, React package, webhooks, or a one-line embed. Google Calendar and Outlook sync. IntoCal reads busy times across your connected calendars and writes every confirmed booking back, so you’re never double-booked. Automatic video links. Each confirmed meeting gets a Microsoft Teams, Zoom, or IntoCal Meet link. Team scheduling. Round-robin distribution, collective meetings with multiple hosts, or guest-picks-host. Branded booking pages. Publish a personal booking page with your own branding, or embed it on any site with one line of code. AI agent booking via MCP. Your hosted MCP server gives compatible assistants live availability and booking access. Setup takes three steps: copy your MCP URL from IntoCal, add it to your assistant, then ask it to find a time and book. Developer tools. REST API, TypeScript SDK, React package, and webhooks for when bookings are created, changed, or cancelled.

Kairo

Kairo is a salon management platform with an AI business advisor built in, made for hair and beauty salons. It is designed for owners who spend the day on their feet, behind the chair. Kairo does what salon software does (bookings, client records, a fiscal-compliant till) and then reads that data every day, the way a business advisor would. Every morning it tells you what matters: clients who are overdue for a visit, empty slots this week, how much discount left the till, which services earn the most per hour of work. Every insight comes with the action ready to go: a win-back message written around that client's history, a promotion for the empty slot, an appointment to move. You approve, Kairo does it. You can also ask it anything about your numbers, the way you would ask a person: "Who should I call back today?", "How much are discounts costing my margin?", "Do I need to hire someone?". On the salon's WhatsApp, on the number clients already know, Kairo answers messages, offers free slots and books the appointment, even after closing. It sends a reminder the day before and asks for a review the day after the visit. The client record keeps the colour formula, processing times, allergies and the full visit history. The till issues fiscal e-receipts and tracks every discount. The Free plan is free forever, with no credit card, and has the same features as the paid plans (Base €59, Pro €99, Business €199 per month), which include more AI tokens each month. Setup takes about two minutes, importing clients, price list and upcoming appointments from your current software.
