Frequently asked questions

Does the other person know their messages are being filtered?

No. They text your Quell number like a normal phone number. They don’t see the rewritten version — only you do.

What if the message is already calm?

Calm messages are delivered as-is with minimal changes. The rewriter only activates when it detects hostility or passive aggression.

How fast is it?

Most messages are rewritten and delivered in under 3 seconds. You won’t notice a delay.

What about emergencies?

Messages about health emergencies, safety threats, or time-sensitive situations are flagged and delivered immediately with all details preserved.

What happens to blocked messages?

When Quell blocks a message (threats, harassment, etc.), you’re notified via email with the category and original content — so nothing slips through without your awareness. You stay informed without the emotional ambush.

Is this just for co-parents?

No. Quell works for any relationship where texts get tense — exes, difficult family members, roommates, and more.

What’s the catch?

There isn’t one. $10/month, cancel anytime. No contracts, no hidden fees. Receive a full refund if you’ve signed up and not received a text message at your Quell number within 30 days. Quell doesn’t store your messages — they’re processed and discarded in real time.
