AI voice · changelogVoice AI: August's cuts came out of the free tiersSeventeen days on from our last sweep we re-captured every pricing page in the directory and set the new screenshots against the old ones. Two platforms made a change that matters, and here is the uncomfortable part: neither change moved a single dollar figure, so the automated price comparison we run first saw nothing at all. Both cuts landed on the free tier instead. This edition covers 30 July to 16 August 2026.2026-08-16 · 8 min read AI voice · analysisWhen your voice platform goes enterprise-onlyBetween our screenshot on 15 June 2026 and our next one on 11 July, Synthflow deleted every price from its website. No announcement, no email that we saw, no migration notice. In place of a pricing table there is now one card saying contracts start at $30,000 a year and a button that says contact sales. If you build on somebody else's platform, this is the failure mode worth planning for, because it is not a bug and it is not a wind-down.2026-08-16 · 9 min read AI voice · changelogVoice AI in August 2026: every verified changeOur July sweep re-captured every pricing page in the directory and set the screenshots against the previous pair. Three platforms moved their prices, four changed a banner and hoped you would read it as news, and the European Commission quietly published the document that decides whether your voice agent has to announce itself. Here is every change we can show you a capture for.2026-08-01 · 9 min read
