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.
What is Survicate?
Survicate pivots from survey tool to AI-native research platform with Research Hub.
On May 22, 2026, Survicate replaced Insights Hub with Research Hub — a project-based workspace that connects surveys, support tickets, call transcripts, app reviews, and 15+ other feedback sources, producing stakeholder-ready AI-generated reports where every claim links back to the exact feedback it came from. A Research Assistant grounded in the project's own sources handles follow-ups; insights surface and are tracked over time. The prior months show steady survey-craft improvements: in-survey language selectors (March), custom fonts (March), response attributes (March), light/dark theme support (Feb), team-invite role bundling (Feb), and an alternative CSAT calculation (Feb).

PySCF

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.

◆ Current state

◆ Where it's heading
The directional move is clear — from "survey tool" to AI-native research platform. The earlier Research Assistant work in January and February was the stepping stone; Research Hub is the destination, and the rebrand from Insights Hub signals the team treating this as a category move, not a feature add. Survey-builder work continues but now reads as table-stakes maintenance underneath the new platform layer.
◆ Prediction
Expect Research Hub to grow new source integrations (sales-call platforms, support systems beyond ticket text) and pre-built templates for common B2B-SaaS research patterns — churn analysis, win/loss, NPS driver mining. Deeper report sharing and distribution would put Survicate directly in Dovetail and Sprig's path.
