IEEE's research library of journal articles, conference papers and standards across computing, electrical engineering, AI and robotics.
From the site: Search and browse IEEE journals, conference proceedings and standards; abstracts are free, full text usually requires a subscription or purchase.
Why I recommend it: Paywall warning: searching and reading titles, abstracts and citations is free, but most full papers need a subscription, an institutional login or a per-article purchase. Some papers are open access and free in full. Check your school or public library for access before paying, and look for the same paper on the author's own site or arXiv first.
Subscription tech newsroom covering AI labs, funding and executive moves, known for scoops on OpenAI, Anthropic, Google and Meta well before wider coverage picks them up.
Why I recommend it: Honest warning: this one breaks the site's 100%-free rule. Almost everything is behind a paid subscription — you can read headlines and the opening lines, and a few free briefings, but full articles need a paying account. Added at my request as a reporting source; treat it as a headline tracker rather than something you can read end to end.
