Message Viktor in Slack like you'd message a teammate. "Send this month's invoices in ProAbono to the customers on this list." "Find the customers in ProAbono with a failed subscription payment and draft outreach." Plain English, any tool.
Viktor opens ProAbono, runs the work, and posts back what changed. Sensitive actions wait for your approval. Everything is logged. You stop doing the work and start reviewing it.
A ProAbono AI agent is an AI that connects to your ProAbono account and completes work in it - it doesn't just answer questions about ProAbono, it takes the actions. Viktor is that agent: an AI employee that works in ProAbono on your behalf and delivers the finished result in Slack or Microsoft Teams.
Unlike workflow builders such as Zapier or Make, there is nothing to configure - no triggers to map, no workflows to maintain. You describe the outcome in plain English, and Viktor picks the right ProAbono actions, chains them with the other 3,200+ tools it connects to, and asks for approval before anything sensitive runs.
ProAbono is the smart subscription management software that automates your daily routine.
Scoped API keys - Viktor stores your key securely, uses only the scopes you grant, and you can revoke it at any time.
Review-first approvals: sensitive ProAbono actions wait for your sign-off before they run.
Isolated compute per team, encrypted in transit and at rest - and your data is never used to train models.
SOC 2 Type 1 compliant, with Type 2 and ISO 27001 in progress.
Yes. ProAbono is one of the 3,200+ tools Viktor connects to, via a managed connector. Once connected, anyone on your team can put Viktor to work in ProAbono from Slack or Microsoft Teams - no workflow builder, no code.
