About SIA
Sia answers questions about your work — by writing or by speaking. In Greek, English, Spanish or Romanian. You connect your CRM, your calendar, your email and your files. Then you ask in your own words: "what's on tomorrow morning?", "find the record for the client I spoke to yesterday", "send the quote we discussed". Sia reads your systems and answers with facts, not guesses. NOTHING IS WRITTEN WITHOUT YOUR APPROVAL Every action that changes something — an email, a message, a meeting, a CRM record — appears first as a card showing the recipient, the subject and the full text. Until you tap Approve, nothing has changed anywhere. TALK INSTEAD OF TYPING Start a call and have a normal conversation, with interruptions and changes of mind. Everything said is written out below, so you don't have to remember it. There is dictation too: the microphone types into the box and stops on its own — it sends nothing. FOUR LANGUAGES Greek, English, Spanish and Romanian — the interface, the messages, and Sia's own voice. Switch on the sign-in screen or later under Account. You can also ask her to change language in the middle of a call. YOUR AGENDA Overdue, Today, Week, Upcoming, Someday. With optional reminders when the time comes — asked for only when you turn them on. WHAT CONNECTS ArgonCRM · Google (Calendar, Gmail, Drive) · Microsoft 365 (Outlook, OneDrive) · WooCommerce ARTIFICIAL INTELLIGENCE, AND WE SAY SO Sia is an artificial intelligence system — no human answers. Before anything is sent, the app shows you by name who receives what: microphone audio goes directly to OpenAI Ireland Ltd, and the text of your requests to Anthropic PBC. Conversations are deleted automatically after 90 days, and you can delete your account permanently from inside the app, whenever you want. An Argonstack account is required.
