Plain
Plain built an autonomous support agent, and has now built the controls to trust it.
A side-by-side editorial comparison of Plivo and Sleekplan — release velocity, themes, recent moves, and the top alternatives to consider.
Plivo's CPaaS hygiene work — but the feed is now over a year stale.
The most recent entry is from January 2025, and the rest land between August 2024 and November 2024. The visible work covers CPaaS table-stakes: dynamic usage-based pricing, automated India-number activation, self-service security/profile management, expanded CNAM coverage, voice-invoice transparency, and Verify API parameter additions for branded auth flows.
Sleekplan rebuilt itself around AI triage, then put the feedback board inside ChatGPT.
Releases are infrequent and arrive as monthly digests with truncated bodies, so scope has to be inferred from direction. The June 2.0 rebuild replaced the admin app and added an AI layer for handling feedback; July connects a workspace to ChatGPT, anonymizes identities on public boards, and adds @-mentions to composers. A rebuilt Chrome extension sits between them, aimed at capture from other tools.

What's in the feed is a steady but unglamorous platform-broadening cadence — geo expansion (India), regulatory plumbing (CNAM, toll-free verification), and pricing flexibility — with no AI, no agentic-voice, no LLM-meets-telephony moves. The bigger signal is the silence: a 16-month gap between the last entry and now, which either means the changelog has moved or the public-facing release stream has gone quiet.
If Plivo is still shipping, the next directional move would almost certainly involve AI voice agents or LLM-powered messaging — every CPaaS peer (Twilio, Vonage, Telnyx) has made that pivot. The absence of any such signal in this batch is consistent with a feed that's no longer the primary changelog surface; the next confirmation will be either a new release stream appearing or a long-overdue entry breaking the silence.

Both ends of the loop are being pushed out of Sleekplan's own interface. Capture moves to the browser extension where support and sales already work; management moves into the assistant a product manager already has open. The Impact Score rework and identity anonymization address the two objections that follow — that prioritization is opaque, and that public boards leak customer identity.
Expect the ChatGPT connection to be joined by other assistant surfaces on the same pattern, and the 2.0 beta to reach general availability with the AI triage layer as its headline.
