SpeechifyAI is one per-minute rate with the LLM included. Most competitors quote a platform fee, then bill the LLM and telephony on top. Drag your monthly minutes and switch the competitor to see the difference. Rates are from each vendor's public pricing.
One line item. No passthrough, no token math.
Rates vary by usage, region, and contract.
SpeechifyAI at the $0.07/min Pro rate, LLM included; Scale drops to $0.068 and Enterprise to $0.06. Competitor "+" items are billed separately on top of the platform fee, so a competitor's true all-in is higher than its headline rate.
| Monthly volume | SpeechifyAI, all-in ($0.07/min) | Synthflow trial rate ($0.08/min) | You save |
|---|---|---|---|
| 1,000 min · ≈200 calls | $70/mo | from $80/mo | $10/mo + |
| 6,000 min · ≈1,200 calls | $420/mo | from $480/mo | $60/mo + |
| 20,000 min · ≈4,000 calls | $1,400/mo | from $1,600/mo | $200/mo + |
The "+" marks the LLM and telephony Synthflow bills separately on top of the platform fee — so the true saving is larger than the platform-fee gap shown.
Synthflow's main pricing page leads with enterprise contracts starting at $30,000 a year, scoped by volume, integrations, and security review. The compare pages surface a 14-day trial with $10 in free credits instead. SpeechifyAI keeps the price public: $99 a month for 1,200 minutes at $0.07 a minute on Pro, and $499 a month for 6,000 minutes at $0.068 a minute on Scale, with the rate readable on the pricing page and no procurement cycle to start.
Synthflow's pitch is a no-code visual builder for non-developers, in-house telephony, and a security checklist. SpeechifyAI covers the same surface area: a visual workflow editor, the same telephony posture (included or bring-your-own carrier), SOC 2 Type II compliance, and the same evals on a published self-serve rate rather than a sales-led conversation, with rates that only get better as workload scales into a real contract.
SpeechifyAI is a published self-serve rate from $0.07 a minute on Pro at $99 a month, with the same workflow editor, evals, tool calling, telephony, and SOC 2 Type II compliance that an enterprise contract would require, without an annual contract minimum.
