Tacit OS: desktop apps, AI agents and the USB trial

What the desktop brings together

Tacit is a free, Arch-based Linux operating system with its own desktop and everyday applications. Praxis puts supported AI agents, including Claude Code and Codex, in a dedicated app. The video explains the documented workflow: start a task, close the window and receive a notification when the agent finishes.

The operating system being free does not make every AI service free. You use your own provider accounts, with their normal prices and limits. Check the account and model requirements for the agent you intend to use.

1. Open the official Tacit site and compare the desktop with the tasks you already do.
2. Check which provider account your chosen Praxis agent requires.
3. Review the agent’s access and inspect its output before relying on a completed task.

Find the everyday applications

The video introduces Graphis for editing code, Pinax for files and Thyris, a Chromium-based browser with ad and tracker blocking. These sit alongside the agent workflow; an integrated assistant is one part of a complete desktop.

Use the official documentation to check current features. This coverage does not establish performance, compatibility with all applications or a hands-on comparison with another operating system.

Check the USB trial requirements

The official installation page says you can try Tacit from a USB stick before choosing to install. It lists an Intel or AMD PC using UEFI, an 8 GB or larger USB stick, and a plugged-in charger. Writing the image erases the USB stick, so use one whose contents you have backed up.

For a Windows dual-boot installation, the guide currently lists about 65 GB of free disk space; using an entire disk requires a disk of at least 32 GB. Requirements and downloads can change, so follow the linked current guide.

1. Open the official installation guide below and confirm that your computer meets its requirements.
2. Download Tacit from the official page and check its provided checksum.
3. Follow the documented Rufus or balenaEtcher route to prepare the USB stick.
4. Boot the trial and inspect the desktop before deciding whether to install.

Review the installation choice before changing a disk

The current official guide describes installing beside Windows or replacing the contents of a disk. It also covers Windows shutdown, BitLocker and Secure Boot requirements. Read those steps in full before changing security or disk settings, and keep a separate copy of important files.

The video is an introduction based on Tacit’s documentation. Luke did not perform an installation or performance test for it; the guide should help you decide what to investigate, rather than stand in for tested compatibility evidence.

1. Back up important files to a separate location.
2. Read the current Windows preparation and boot requirements in the official guide.
3. Check the selected disk and the proposed installation layout before confirming any write.

The takeaway

Try the desktop and check account and installation requirements before committing to a new operating system.
