Sayelo at a glance: the AI voice agent that answers calls for you

Sayelo is a French AI voice agent that answers calls 24/7 for micro-businesses, SMEs and independent professionals, gives callers information, books appointments in the calendar and transfers urgent calls. The agent announces itself as an AI in its first sentence and sends you a summary of every call by email.

Sayelo costs from €39 excl. VAT a month, with 4 plans up to €279 excl. VAT a month depending on minutes, agents, simultaneous calls and number of users. The trial is free for 14 days and there are no set-up fees. Details are on the pricing page.

Yes: data is hosted by an HDS-certified host (health data hosting provider), on all plans, including the entry-level one. The agent sticks to booking appointments and practical information, and never gives medical advice.

Numbers and telephony are provided by a partner operator registered with ARCEP (the French telecoms regulator). You keep your current number, as you prefer: by forwarding it to your agent or, in France, by porting it, on all plans. A new number is also included from the start of the trial, if you would rather start from scratch. If you use your own number (forwarded or ported), it remains yours. A number assigned by Sayelo is taken back at the end of the subscription.

Sayelo integrates natively with Sellsy and monday.com, and sends webhooks to your other software. For calendars, it reads and writes live in Google Calendar, Microsoft 365 and Cal.com; other calendars on request.

Depending on the plan, 1, 2, 5 or 10 simultaneous calls: 1 on Solo, 2 on Essentiel, 5 on Pro, 10 on Business. Details of each plan are on the pricing page.

Depending on the plan, from 1 to 5 people: 1 on Solo, 2 on Essentiel, 3 on Pro, 5 on Business, and on Custom, 5 users, more on request. Each person logs in with their own email, as “Administrator” or as “User”: a user only sees and manages the agents within their scope. The activity log keeps a record of who did what for one year. Teamwork is only available in the new version of the app.

Yes. You talk to your agent in the app, in writing, by dictation or in a voice conversation: it updates you on your calls and adjusts its own opening hours, closures, greeting, instructions, transfers and what it can answer. Sensitive actions wait for your approval. A few things still have to be done on screen: connecting a calendar or a CRM, paying, activating outbound calls (only in France for now).

Exceptional closures (time off, public holidays, long weekends) without changing your usual opening hours: the agent plays your message, hangs up or transfers the call, and books no appointments during the closure. You add it in “What it does” → “Opening hours”, or simply by asking your agent.

Nearly 100 languages included in all plans. With the “Multilingual agent” option, the agent switches to the caller's language from the first few words, and the summary always reaches you in your account's language.
