What's New in Cornelius v05.26

Released May 2026 · Cornelius versions are named for their month (vMM.YY)

Corneliusis the open-source second-brain agent built for Trinity — a company or personal brain that compounds, with receipts. This is a Cornelius release, not a Trinity one. New here? Start at Cornelius.

v05.26 adds the autonomous loop: a perception layer that notices what is new, and a thinking engine that keeps working on open questions across scheduled runs. And a way to get your own thinking out of your head — one question at a time.

What changed

•Incubation loop — autonomous iterative thinking engine; each run applies a rotating analytical move (ACH, Bayesian update, steelman, cross-domain bridge, implication check) and persists reasoning state across scheduled runs.

•Domain watch — autonomous perception layer that scans the KB for new notes matching configured domains, checks gap resonance, and probes external signals to auto-activate topics for the incubation loop.

•Insight interview — KB-grounded Socratic dialogue; searches existing notes on a topic then runs a one-question-at-a-time session to surface and sharpen your thinking, saving results as permanent notes.

•YouTube transcript — extract transcripts from any YouTube video for processing into the knowledge base.

•deep-research Phase 4 — an optional insight-interview step before connection discovery, capturing your personal angles alongside extracted research (/deep-research).

•45 skills — for insight capture, autonomous thinking, connection discovery, research, and content creation.
