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.
