Plainwork
vs OpenAI Codex

Both can act across your apps, but they start from different places. OpenAI Codex is a coding agent that now drives your screen when you prompt it. Plainwork detects what you repeat on its own and proposes the automation, no prompting needed.

Why Plainwork

Four reasons people
move over

01

It runs on your device

Capture, storage and detection all happen locally. Your screen activity never leaves the device it was recorded on.

02

There is nothing to set up

It watches what you repeat and proposes the automation. No prompts, no building.

03

It works with your oldest apps

Even the clunky internal software nothing else can automate. If you can click it, it can repeat it.

04

You approve every action

It proposes. Anything that sends, deletes or pays waits for you every single run.
