Plain renames AI agents: Ari is now Customer Agent, Sidekick now Sidekick Agent
What happened
Between the Oct 26, 2026 and Nov 2, 2026 captures of Plain's pricing page, Pulse recorded one change: AI agents renamed: Ari (customer AI agent) is now Customer Agent and Sidekick (internal AI agent) is now Sidekick Agent; credits and prices unchanged. Pulse files it as a product change (positioning) with a neutral direction. The current page lists Foundation at $45 and Horizon at $99.
It lands 21 days after Plain's previous change, "Plain adds $10-$100 credit top-ups, doubles Foundation credits to 1,000/month" (Oct 12, 2026). Before that Pulse recorded "Plain swaps seat bundles for $45 and $99 per-user pricing, cuts AI credits" (Oct 5, 2026). Plain has been tracked since 2026-03-02.
In the same window Stripe and Squarespace also changed their CRM pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
