Is Callable alone on unmetered calling and a sub-1% AI detection rate?
A scan of published voice-AI pricing models and of published AI-detection evidence. It rejects one of our own claims and supports the other in a narrower form.
Published · Measured Scanned August 2026
The only published rate
Measured — published methodAs at August 2026 we could not find another voice-AI vendor, analyst or academic source publishing a measured AI-detection rate with a stated denominator, criterion and corpus size. CallableAI's 0.25% appears to be the only one in the public record.
Measured Scanned August 2026
Method
- A structured scan of public vendor pricing pages and independent 2026 pricing comparisons, plus a search for any published AI-detection measurement from a voice-AI vendor, analyst or academic source that states a method.
- Two claims were tested separately, because they fail and pass differently: that CallableAI is the only vendor with unmetered calling, and that CallableAI's detection rate is unmatched.
- The first did not survive. Flat-rate voice AI does exist. The claim we can defend is narrower — unmetered calling at outbound scale, with no per-minute line on the invoice across hundreds of thousands of dials a week, where the rest of the market bills per minute.
- The second did survive, in a precise form: vendors market naturalness heavily, but none publishes a detection rate with a defined denominator and criterion.
How the market bills — these are alternatives to Callable, not components of it. Verified August 2026; pricing changes often
| Platform | Model | Published rate | Unmetered? |
|---|---|---|---|
| Vapi | Platform fee + model passthrough | $0.05/min + speech/model/voice on top (~$0.15–0.31 all-in) | No |
| Bland | Bundled per-minute | $0.11–$0.14/min | No |
| Retell | Itemised per-minute | ~$0.07–$0.31/min | No |
| Vociply | Minute bundle + overage | $299–$749/mo, then $0.25–0.26/min | No |
| Nedzo | Outcome-based | $299–$499/mo, then $1.99/outcome | No — metered on outcomes |
| QCall.ai | Per-channel unlimited | $549 per channel/mo, 1 concurrent call each | Partly — capped by paid channels |
| OpenVoice Agents | Flat infra, bring-your-own-key | $199/mo unlimited infra minutes | Partly — model cost still metered |
| KaiCalls | Flat monthly receptionist | From $69/mo, tiered by expected call count | Partly — plan tiers by volume |
| Callable | Flat subscription, throughput sized by concurrency | Flat monthly fee; calling not billed per minute | Yes |
Published detection evidence in the market
| Source | Setting | Rate | Evidence quality |
|---|---|---|---|
| Excite Labs (Nov 2025) | Inbound customer service | 15–20% of callers identify AI | Qualitative review; no denominator or criterion published |
| Practitioner reports (2026) | Outbound cold calling, ~11,400 dials | “Most never noticed” — no figure | Anecdotal; no method |
| Callable CA-2026-01 | Outbound production, 30 days | 0.25% (253 of 102,154) | Full-corpus transcript scan; criterion and denominator stated |
What this number does not say
- The 15–20% figure is not a like-for-like comparison and must never be presented as one. Excite Labs measured inbound service calls, where the caller dialled a company and is primed to expect an IVR. CallableAI measures outbound, where the recipient has no prior frame. Different populations produce different base rates — treat it as context, not a benchmark, and do not compute a ratio between the two.
- “No published rate elsewhere” is an absence of evidence established by search, not proof that no vendor has measured one internally.
- The pricing scan only sees vendors with public pricing pages. Private enterprise contracts are invisible to it, and a competitor may offer flat-rate terms that are never published.
- Competitor pricing was verified against the cited pages in August 2026 and changes frequently. Treat the table as dated evidence, not a live comparison — it is on the quarterly refresh list.
- CallableAI is not the only vendor selling flat-rate calling, and we do not claim to be. What we have not found elsewhere is flat-rate calling that stays flat at outbound scale: the comparable offers meter concurrency, pass model spend through to your own provider account, or size plans around roughly 150 answered calls a month.
