FIDEX I

Features

Built to do the work,
not just talk about it.

Autonomous agent

Give it a goal. FIDEX SI researches, plans and carries out the steps on your Windows computer.

Approval first

It asks before publishing, messaging, spending money, deleting files or anything irreversible.

Remembers your work

Current, finished and unfinished tasks, past decisions and instructions are kept so you can pick up where you left off.

Take Over

Tell it to start something or continue from where you stopped. It builds from beginning to end alone: clicking, creating files, using other AI tools if you choose, messaging customers and more.

Works offline

No internet needed. FIDEX SI keeps working on your machine even when you are disconnected.

Vision

It has every organ it needs to carry out tasks, like a real humanoid robot sitting at your system and doing the work.

How FIDEX SI works

From idea to finished in five steps.

  1. 1

    Tell it the goal

    Type a command or a mission in plain language.

  2. 2

    It thinks and plans

    The brain reads your request and writes step one immediately, while the rest follows.

  3. 3

    Hands start working

    Actions begin while the plan is still being written. You see progress as it happens.

  4. 4

    You approve what matters

    Important actions wait for your yes. Everything else just gets done.

  5. 5

    It finishes and delivers

    It completes the task and delivers the final message. It can take over for a whole day.
