Stop spam before it rings
2Line.AI labels likely spam before your phone rings, lets you block or unblock any number in one tap, and can let Mia by 2Line.AI screen unknown callers so only real customers reach you.

What you get
A business number goes on signs, listings and websites, and spam callers find it fast. Every robocall pulls you off a job, and ignoring unknown numbers means ignoring new customers too.
2Line.AI tries to get you the middle ground. Likely spam is labelled, blocked numbers stay blocked, and unknown callers can go to Mia, who finds out what they want and leaves you a slip.
Likely-spam label
Calls that look like robocalls are marked before you answer.
Block in one tap
Block a number from the call, the text or the contact. Change your mind with undo.
Mia screens unknown callers
Unknown numbers can go to Mia first. You get a slip saying who called and why.
Silence unknown callers
Turn it on and numbers you don't know stop ringing you. Mia still answers them and leaves a slip.
How spam blocking works
- 1Spam gets a labelCalls and messages from numbers that look like robocalls show “Likely spam”, unless the number is in your People.
- 2Block in one tapFrom a call, a text thread or a contact. Pick a reason, like spam, scam or harassing calls. Undo if you tapped by mistake.
- 3Silence unknown callersNumbers you don't know stop ringing your phone. Mia still answers them and leaves you a slip.
- 4No automatic texts to spamMissed-call texts, reminders and review requests never go to blocked numbers, and missed-call texts skip likely spam.
- 5Unblock any timeBlocked numbers lists everyone you've blocked. Unblock from there.

| Missed-call text back: To | New callers only, or everyone except blocked numbers. |
What it costs
Labels, blocking and silencing are free. Say Mia screens 10 unknown callers in a month, about a minute each. That’s 490 credits. The cheapest way to cover it is one 950-credit pack ($19.99), on top of your plan. Your real use will differ.
| Likely-spam labels, blocking, silencing | Free |
|---|---|
| Mia, 10 calls × 1 minute | 48 × 10 = 480 credits |
| AI summaries | 1 × 10 = 10 credits |
| Total | 490 credits, covered by $19.99 in packs |
Missed spam calls are free, and no missed-call text goes to likely-spam numbers. Plans are $19.99 a month or $99.99 a year with a 3-day free trial, and start with 100 credits, once. Credits don’t refill each month; packs start at $4.99. See all rates.
Get more out of spam blocking
- Don't press buttons or say “yes” on a robocall. Hang up and block.
- Block from the call or the text right away. Undo is there if you were wrong.
- If most of your work comes from new numbers, don't silence unknown callers. Let Mia answer instead.
- Add regular customers and suppliers to People, so they never look unknown.
- Report robocalls to the FTC too. Our spam guide shows how.
