Englify – Fix My Comment by Jem Works

Write first, fix later. Englify adds a one-click "Fix English" button directly inside comment boxes on X / Twitter and YouTube, so you can clean up your grammar, spelling, and phrasing without leaving the page.

How it works
─────────────────────────────

Type your comment as you normally would.
Click the Fix English button next to the Post button.
Review the AI-suggested rewrite side by side with your original.
Choose to apply the suggestion, keep your original, or edit either version before posting.

Features
─────────────────────────────

✦ Seamless injection — The Fix English button appears automatically next to the submit button on every supported platform. No copy-pasting, no switching tabs.

✦ Side-by-side review popup — Before anything changes, you see your original text and the AI suggestion in an editable comparison modal. Both sides are fully editable, so you can mix and match the best of both versions.

✦ Instant apply mode — Prefer speed over review? Toggle off the comparison popup in Settings and rewrites are applied immediately with a single click.

✦ Tone control — Choose how your rewritten comment should sound. Available tones: Professional, Casual, Friendly, Formal, Confident, Empathetic, Humorous, or Concise. The selected tone is automatically applied to every rewrite.

✦ Supported platforms
— X / Twitter (twitter.com and x.com)
— YouTube (youtube.com)

✦ Secure authentication — Sign in once with your englify.social account. Your session is stored locally on your device and automatically refreshed — no repeated logins.

✦ Privacy-first — We do not store the text you write or the rewritten version on our servers. The only data we save is anonymous usage metrics — such as the number of rewrites, word counts, and dates — to power your dashboard analytics.
