Actaa AI

Actaa AI is a business operating system with a private AI built in. Mail, chat, calendar, documents, projects, files, knowledge, people, hiring, sales, operations and finance run on one system, one login and one set of permissions. Core functions Mail — a business mailbox on your own domain, with spam and phishing protection, shared and delegated mailboxes, rules, snooze, undo send, and retention and export controls. Messages, calls and announcements — channels and direct messages, video and audio calls with screen share and waiting rooms, company announcements with read tracking. Files and ActiveSpace — a company drive with safe preview, virus scanning, version control and a Vault for sensitive files, plus Write for documents, Tables for spreadsheets, Present for slides, Board for whiteboards and Notes. Word, Excel and PowerPoint files open and export back. Knowledge — a wiki, playbooks, training courses with quizzes and certificates, and a Data Room you can ask questions of. Tasks and projects — tasks, dependencies, checklists, projects, milestones, roadmap and automations, with every progress number computed rather than estimated. Calendar and meetings — scheduling with clash checks, a one-page brief before each meeting, and recorded meeting notes with action items that become tasks. Daybook — tamper-evident attendance and time, with consent recorded before tracking starts, shifts and rosters, breaks, overtime approval, corrections and monthly statements. People and HR — the employee record from onboarding to offboarding, time off, policies, reviews, equipment, concerns and engagement. Hiring — job posts with public job pages, an applicant pipeline, interviews, document requests and offers, flowing straight into onboarding. Sales — contacts and deals built from your own mail, with lifecycle stages worked out from what actually happened. Operations — 21 business types, so a salon sees Bookings and Clients while a builder sees Sites and Reports. Finance — quotes, invoices, expenses, budgets, bills, payroll, bank reconciliation and a full double-entry ledger. The private AI Ask Actaa sits on every page and knows what you are looking at. Behind it, a company brain answers from tasks, projects, files, documents, boards, wiki, playbooks, calendar, meeting notes, chat digests and sales — always limited to what the person asking is already allowed to see. HR and Finance data never enters that assistant. Those two modules have their own separate ones. The AI proposes and a person decides. It never sends mail, pays, posts or judges a person on its own. Admins choose which models are used, which data the AI may read, who gets it, and the monthly budget. Several leading models are available, and Roundtable lets them answer the same question side by side. In hiring, personal details are removed before the AI sees a candidate. It summarises what the candidate wrote and never scores or ranks a person. Security and control Every workspace is separated at the database level. Passkeys and two-step sign-in, roles and permissions down to single features, a full audit log, retention rules, legal hold, company data export and personal data erasure on request. Getting started One-click import brings in mail, calendar, contacts, files, tasks and people from the tools you use now. Actaa is 5.99 US dollars per person a month, with every module on every seat and nothing held back for a higher tier. A 14-day free trial covers up to five people. The AI is one plan for the whole company, from 29 dollars a month, rather than a charge on every seat. Actaa AI is a product of Nomisma LLC, founded 2022, in Sheridan, Wyoming, United States. Actaa is not affiliated with any other company with a similar name.
