What is Appcues?
Appcues drops Embeds — in-product experiences that live inside the UI rather than overlay it.
Appcues is a product-adoption platform whose recent quarter has run two parallel storylines. Captain AI, the in-product assistant, has gone from a chat helper to something that drafts segments, analyzes funnels, diagnoses display problems, and explains performance — adding capability essentially every monthly release. Alongside that, the team has expanded the experience surface itself: an MCP Server that exposes Appcues data to ChatGPT and Claude, and Embeds — a new experience type that lives inside the product UI rather than as an overlay.
What is Calibre?
Calibre MCP lets your coding agent read RUM and Lighthouse data, then fix the slow code
Calibre now ships a read-only MCP server that gives Claude Code, Cursor, Codex, Copilot, Claude and ChatGPT access to an account's RUM, CrUX and Synthetic data, included on every plan. It came days after Test Agents moved to Chrome 156 and Lighthouse 13.6.0. The latest entry is a design tidy-up that places each page's Guide link in the same top-right spot.

Appcues drops Embeds — in-product experiences that live inside the UI rather than overlay it.
◆ Current state
Appcues is a product-adoption platform whose recent quarter has run two parallel storylines. Captain AI, the in-product assistant, has gone from a chat helper to something that drafts segments, analyzes funnels, diagnoses display problems, and explains performance — adding capability essentially every monthly release. Alongside that, the team has expanded the experience surface itself: an MCP Server that exposes Appcues data to ChatGPT and Claude, and Embeds — a new experience type that lives inside the product UI rather than as an overlay.
◆ Where it's heading
Appcues is reframing what an 'in-product experience' tool covers. Embeds break the long-standing overlay-only model that defines the category (Pendo, Userpilot, Chameleon all anchor on overlays). MCP exposes the same data surface to external AI tools, which makes Appcues a source as well as a destination. Captain AI keeps absorbing operator tasks — segmentation, funnel analysis, install diagnostics — turning the product manager's in-tool workflow into more of a conversation than a configuration session.
◆ Prediction
Expect Captain AI to start fully building things autonomously rather than drafting (the team teased this in the January notes), and for Embeds to gain a bigger pattern library now that the underlying primitive is shipped. The MCP server integration line will likely grow with more bidirectional actions exposed to external AI tools.

Calibre MCP lets your coding agent read RUM and Lighthouse data, then fix the slow code
◆ Current state
Calibre now ships a read-only MCP server that gives Claude Code, Cursor, Codex, Copilot, Claude and ChatGPT access to an account's RUM, CrUX and Synthetic data, included on every plan. It came days after Test Agents moved to Chrome 156 and Lighthouse 13.6.0. The latest entry is a design tidy-up that places each page's Guide link in the same top-right spot.
◆ Where it's heading
Calibre is turning its monitoring data into something agents act on rather than something people read in dashboards. The summer work on deployment markers, all-pages aggregates and the audit log built the context and governance an agent needs: which deploy, which page, who connected. Expect the remaining surface to follow the same path, with agents both querying performance and being measured by it.
◆ Prediction
The likely next step is write access or deploy-linked workflows over MCP, such as an agent opening a fix tied to a regression marker, since the current server is explicitly read-only and the launch frames fixing as the goal.
