About this app

Actaa brings the tools your company runs on into one system, with a private AI built in. One login. No more switching between ten different apps.

EMAIL ON YOUR OWN DOMAIN
Get you@yourcompany from day one. Your inbox sits beside your chat, files and projects, and the AI can draft, summarize and find messages for you.

CHAT THAT FITS THE WORK
Channels, threads and calls live in the same place as your projects. Checklists tick right inside the conversation as work gets done, and the AI can catch you up on whatever you missed.

CALENDAR WITH VIDEO BUILT IN
See every meeting beside your mail and chat. Join a video call in one tap from the event, and keep time zones sorted for the whole team.

PROJECTS AND TASKS
Follow every project, its tasks and its owners in one view. Tasks stay next to the chat, files and calendar they belong to.

DOCUMENTS AND FILES
Write, build tables, present and take notes together, live, with the AI drafting and editing alongside you. Your .docx, .xlsx and .pptx files open and save faithfully, and you decide file by file what the AI can read.

PEOPLE AND FINANCE
Run hiring, onboarding, reviews and time off from one place. Send invoices, approve expenses, and manage payroll and your ledger without leaving the system.

A PRIVATE AI FOR YOUR COMPANY
Actaa's AI is your company's own. It is never trained on your data, it answers only what you are allowed to see, and your personal files are never read.

YOU STAY IN CONTROL
Roles and permissions decide who can see what, and you choose what the AI can read. Every module can be turned on or off per team.

BUILT FOR
- Startups that want everything ready on day one
- Teams that want fewer tools and one place to work
- Companies that care about keeping their data private

Download Actaa and run your company from one place.
Run your company in one place: email, chat, files, HR, finance and private AI.
