CallerFilterPro

Editor's pick
4.8

AI receptionist + concierge

AI receptionist that screens every unknown caller — then Upgrade Your Status to a voice-commanded concierge.

The only tool in our test that ships both layers of phone life as a single integrated product. Layer 1 is the standard AI receptionist — replaces voicemail with a live AI that greets unknown numbers, captures intent, and routes through only calls that match your rules; robocalls and scammers don't get past it. Layer 2 is the Status Upgrade — obtained by enrolling in concierge services on top of the base tier — where the same AI handles dinner reservations, spa appointments, travel options, callback scheduling, and reminders by voice command. Works on any phone via call forwarding from your existing number.

Pros

  • +Active screening — caller is engaged in real time, not just labeled
  • +Status Upgrade adds voice-commanded concierge (dinner, spa, travel, reminders) — the only tool in the category that does this
  • +Works on any phone (iPhone, Android, landline VoIP) via call forwarding
  • +Structured intake: caller name, reason, urgency captured as data
  • +Full rule engine: VIPs ring through, blocked numbers handled, contacts routed per profile
  • +Web dashboard with searchable call history and transcripts; printable membership card for Status Members

Cons

  • No free tier — base call-screening starts at $9.99/month
  • Spam-call database is pattern-driven, not the largest in the category (RoboKiller wins on raw block count)
  • Status Upgrade concierge services are a separate enrollment (à la carte from $3-9/mo each, or bundled into the $19.99 Platinum tier)

Best for: Anyone who actively wants unknown callers handled — and especially anyone ready to recover the minutes per day they spend on phone admin by delegating reservations, scheduling, and small-life logistics to an AI by voice.

Pricing: $9.99/mo Gold (screening only) · $19.99/mo Platinum (bundles 2 concierge services) · à la carte concierge add-ons from $5-9/mo Gold or $3-5/mo Platinum

RoboKiller

4.2

Aggressive blocker + answer bots

Largest spam database in the consumer space, with comedic 'Answer Bots' that waste scammers' time.

RoboKiller's flagship is its spam-call database (claims 1.5 billion blocks) combined with its novel Answer Bots — AI personas that engage robocallers in deliberately frustrating conversations. It's the most aggressive blocker we tested. Best fit for users who want maximum block and don't mind that legitimate unknown callers may also get filtered.

Pros

  • +Largest spam-call database we surveyed
  • +Answer Bots are genuinely novel and entertaining
  • +Annual U.S. Robocall Insights report earns press coverage
  • +Solid auto-blocking; few rings reach you

Cons

  • Block-first — legitimate unknown callers may be filtered out
  • No real screening conversation; Answer Bots are after-the-fact
  • No business features (multi-user, transcripts, dashboards)
  • Premium+ family plan ($19.99/mo) is expensive for what is essentially one feature on multiple devices

Best for: Consumers prioritizing maximum blocking who can live with the occasional false positive on real unknown callers.

Pricing: $4.99/mo Premium · $11.99/mo Premium+ · $19.99/mo Family

#3

YouMail

4.0

Visual voicemail + blocker

Smart voicemail with robocall blocking — the right tool if voicemail is your default.

YouMail replaces your carrier voicemail with a visual transcribed inbox and uses a large robocall database to block known bad numbers before they reach your voicemail. Its core paradigm is voicemail-first, which is fine if you don't pick up unknown calls anyway.

Pros

  • +Mature visual voicemail with AI summaries
  • +Free tier exists (ad-supported)
  • +Custom voicemail greetings per contact or time of day
  • +Solid robocall blocking from large database

Cons

  • Voicemail-first — never engages the caller live
  • No structured intake (free-form transcripts only)
  • Limited rule engine compared to dedicated receptionist tools

Best for: Heavy voicemail users who want smart voicemail plus known-spam blocking.

Pricing: Free with ads · $5.99/mo Plus · $14.99/mo Solo · $24.99/mo Professional

#4

Hiya

3.8

Caller ID + spam labels

Pre-installed on hundreds of millions of phones — labels suspect calls so you can decide.

Hiya is the carrier-distributed caller-ID layer on AT&T, Samsung, T-Mobile, and others. It labels incoming calls as 'Spam Risk' or 'Telemarketer' so you can decide whether to answer. It doesn't take action on your behalf — it's an information layer, not a screening tool.

Pros

  • +Pre-installed on hundreds of millions of devices
  • +Reliable spam labeling from carrier-scale data
  • +Free tier covers most consumer needs
  • +Reverse-number lookup is fast and broad

Cons

  • Labels only — doesn't reduce interruption, just renames it
  • No screening conversation, no message intake
  • Auto-block only acts on already-flagged numbers; new spam still rings

Best for: Phone users who answer their own calls and just want a heads-up label before deciding whether to pick up.

Pricing: Free · $3.99/mo Premium

#5

Nomorobo

3.6

Simultaneous-ring blocker

Cheap, simple, landline-friendly. The veteran of the category.

Nomorobo is one of the original robocall blockers. On landlines it's free; on mobile it's $1.99/month. The core technique is a simultaneous ring to Nomorobo's screening service, which hangs up on known bad numbers after the first ring.

Pros

  • +Cheap — $1.99/mo mobile, free on landlines
  • +Battle-tested — one of the longest-running blockers
  • +Available on landlines (most modern competitors aren't)
  • +Simple technique that works for known-bad numbers

Cons

  • Block-only — no screening, no intake, no rules
  • Can't help with unknown legitimate callers
  • Mobile app gets less attention than the landline service

Best for: Households with landlines — especially senior households where landline is still the primary line.

Pricing: Free landline · $1.99/mo mobile

How to choose

The five tools above cover four meaningfully different approaches. Pick by the question you're trying to answer:

“I want unknown callers handled, not just labeled.”

You need a screening tool — one that actually engages the caller. CallerFilterPro is the only entry in our test that does this end-to-end. Google Call Screen (Pixel-only, not in our top 5) is the free alternative if you happen to own a Pixel.

“I want maximum blocking — kill every spam call.”

RoboKiller has the largest spam database we surveyed and aggressive auto-blocking. Trade-off: some real unknown callers may also get bounced. If you don't take new business calls or callbacks from unknown numbers, fine.

“I just want to know which calls are spam — I'll decide.”

Hiya (free, pre-installed on AT&T / Samsung / T-Mobile) does this well. Adds a “Spam Risk” label without taking any action.

“I have a landline (or am setting one up for a parent).”

Nomorobo is free on landlines. It uses a simultaneous-ring blocking pattern that hangs up on known robocalls after the first ring.
