# Eric Porres - porres.com

> Eric Porres is Chief AI Officer at Logitech, writing about AI transformation from the trenches - frameworks, receipts, zero bullshit. porres.com is his personal home; the substantive work lives in the Beyond Reason newsletter, The AI Field Guide, TrialThread, his AI field notes, and a living history of the pianist Dwight Peltzer.

Eric leads AI strategy and platform at a ~7,000-person company and writes Beyond Reason, a Substack on AI and the economy for practitioners. The most complete resources on this domain are The AI Field Guide (a fifteen-card reference on how AI actually works), the Dwight Peltzer living history (sixty documented entries and sixteen preserved recordings of the American pianist, recovered from analog tape), and the AlephBrain field note (decoding a living-brain ultrasound file with ChatGPT and Claude). Each has a plain-text rendering for LLMs. TrialThread is a working tool rather than a piece of writing: a free, open-source agent that reads clinical-trial eligibility criteria in plain English.
