Arcarius is a Swiss AI platform for accounting and finance from Arcarius GmbH in Wallisellen, aimed at fiduciary firms and small and medium-sized businesses. An AI assistant carries out requests given in natural language and prepares bookings that you approve with one click.

According to the vendor, accounting data is stored exclusively in Switzerland. AI processing generally takes place in Switzerland or Europe but, for some features, can also occur elsewhere, including the United States, through providers such as Anthropic, Google and OpenAI.
