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 PySCF?
Quantum chemistry package adding whole method families every release.
PySCF is a Python-based quantum chemistry toolkit, and its release cadence is unusually feature-dense: each version lands multiple new electronic-structure methods rather than polishing existing ones. Recent releases have built out the GW/BSE excited-state stack, k-point RPA for periodic systems, higher-order coupled cluster, and multi-state PDFT with analytical gradients. Platform work runs alongside — Windows DLL compatibility, GPU4PySCF interfacing, and configurable einsum backends.

Appcues

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.
PySCF
2.5ANALYTICS
Quantum chemistry package adding whole method families every release.
◆ Current state
PySCF is a Python-based quantum chemistry toolkit, and its release cadence is unusually feature-dense: each version lands multiple new electronic-structure methods rather than polishing existing ones. Recent releases have built out the GW/BSE excited-state stack, k-point RPA for periodic systems, higher-order coupled cluster, and multi-state PDFT with analytical gradients. Platform work runs alongside — Windows DLL compatibility, GPU4PySCF interfacing, and configurable einsum backends.
◆ Where it's heading
Two arcs are visible. The methods arc is pushing toward periodic (PBC) parity with molecular calculations — PBC GW, PBC RPA, SOC-ECP for PBC DFT, QM/MM for periodic systems all landed in this window. The infrastructure arc is about getting PySCF to run where it previously did not: Windows, GPUs, alternative tensor-contraction backends.
◆ Prediction
The PBC catch-up should continue, since each release closes another gap between molecular and periodic implementations of the same method; the entries do not indicate which gap is next.
