Jinna.ai is an AI assistant for business admin and finance. The company says it helps users create invoices and estimates, follow up with clients, get paid and stay on top of cash flow, so the routine work of running a small business needs less manual effort.
The site presents the product as "Brain & Hands." The brain is a memory of the user, the business and each client. The hands are AI agents that draft proposals, send invoices and follow up until the client pays. The company says more than 1,200 solopreneurs in the U.S. use it.
According to the site, Jinna connects to the user's tools and watches the inbox, calendar and tasks. Its agents organize the day across inbox, calendar, tasks and documents, then draft proposals, send invoices and follow up. The site describes the control model as "You say go, they run."
Users give instructions in plain language, such as asking Jinna to add a client with a name and email, or to create an invoice for a set amount. The memory layer learns from every action, so less needs to be explained over time. Follow-up messages need approval before they are sent.
The product covers the path from first contact to payment. A client list stores contact details, notes and activity. Proposals are shared by link, with view and time stats, and can be converted to invoices. Estimates are shared as a simple link and convert to an invoice in one click.
Invoices can be downloaded as PDF, customized and sent with Stripe payment links and scan-to-pay. AI writes the emails and the follow-up reminders, and the user approves them before sending. The Plus plan adds auto-reminders, company memory, AI skills for business and a Xero integration.
