What people are saying

Dealing with a difficult parent

Why not just block them?

Blocking cuts you off. Doing nothing wears you down. Quell is the middle ground.

	Do nothing	Block them	Quell
Hostile messages	You read every word	You miss important info	Rewritten calm, facts intact
Emergencies	Mixed in with the noise	Blocked entirely	Always delivered immediately
Your replies	Risk escalating	Can’t reply at all	Go through unmodified
Evidence / admissions	Lost in the chaos	Never received	Forwarded verbatim
Your peace of mind	Constantly on edge	Guilt and missed info	Calm and in control

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.
