Where should an in-page writing assistant work perfectly first?

I launched Polish to remove the copy, prompt, paste loop from small writing fixes. It improves selected text inside the web editor you are already using.

The launch itself brought almost no users. That told me I need to test it in real workflows instead of asking for general support.

If you write in Gmail, Slack, Jira, LinkedIn, a support tool, or another web editor, which one should Polish support perfectly first?

A useful test takes about two minutes:

1. Open the demo and install page on desktop Chrome

2. Try one real English sentence

3. Tell me which editor you used and whether the text was replaced cleanly

I am looking for failures and friction, not upvotes.
