Generate regex patterns with AI

Generate regex patterns with AI

Tip — start your description with an action word matching the tab you're on. This ensures the AI generates a pattern that fits your rule type:

• Block tab → start with "Block" or equivalent words: stop, prevent, deny, ban (e.g., "Block SEO ahref bots")
• Redirect tab → start with "Redirect" or equivalent words: send, route, forward (e.g., "Redirect all AI crawlers to homepage")
• Whitelist tab → start with "Allow" or equivalent words: permit, whitelist, accept (e.g., "Allow Googlebot and Bingbot")

How to use:

1. After selecting Regex as the Type, click the Generate with AI icon (✨) on the right side of the "Regex pattern" input.
2. In the panel, describe the bots, browsers, or traffic you want the rule to match (see the tip above for how to phrase your description).
3. Click Generate. Blockify will show you:
4. • The generated regex pattern with a copy icon so you can copy it anywhere.
   • A What this rule does explanation in plain English.
   • Sample user agents tagged as Matched (green) or Not matched, so you can see how the rule behaves on real examples.
   • A Test your rule input where you can paste any User-Agent string to verify the match.
4. If the result isn't quite right, click Regenerate to try again.
5. When you're satisfied, click Use this rule — the generated pattern is automatically filled into the Regex pattern field above. You can still edit it by hand before saving.

The screenshot above shows the Block tab — the flow works the same way in the Redirect and Whitelist tabs.

Note: You can generate up to 10 times per day. The daily limit resets 24 hours after your first generation of the day.
