I built TextBoi, a desktop tool that lets you proofread or translate text anywhere using a simple hotkey.

Most AI writing tools or GPT wrappers follow a workflow like this:

select text → trigger shortcut → choose an action → run

Even though it’s faster than copy-paste, it still breaks the writing flow if you repeat the same task many times.

TextBoi takes a slightly different approach.

You choose the action first (for example proofreading, translation, or rewriting). After that, the workflow becomes:

select text → press Cmd+C+C on Mac (or Ctrl+C+C on Windows) → done

Because the action is already selected, you can repeat the same task very quickly without opening menus or switching apps.

The goal was to make AI feel more like a native desktop shortcut rather than a chat interface.

It works across apps like browsers, email clients, Slack, and IDEs.

There is a small free tier for light use (around 30k characters), and a $5/month plan designed for heavier usage (up to around 10M characters per month).

I'm a solo developer and built this as a side project over the past several months. I'd really appreciate feedback from the HN community.
