  • Tools I'm Using in 2026 (and what I've stopped using from 2025)
    Last year I was heavily into Perplexity but for most of 2026 I've actually been using NotebookLM a lot more. Perplexity is still useful for just daily news, but when I want to research, when I want to summarise, when I want to learn... NotebookLM all the way. - Source: dev.to / about 1 month ago
  • NotebookLM Skills: Give Claude Code a Brain That Doesn't Hallucinate
    NotebookLM already sorted this on Google's side. You upload your sources, Gemini answers only from those sources, every answer comes with citations pointing to the exact passage. The catch was it's browser-only. No API. No way to wire it into your agent workflow. - Source: dev.to / 2 months ago
  • How did I pass the AWS Certified Solutions Architect โ€“ Professional 2026 exam?
    In Notebook LLM, add the information sources you use for studying and use different formats. It currently supports Latin American Spanish. - Source: dev.to / 3 months ago
  • Automating Roadmap.sh into NotebookLM
    Then there's NotebookLM. For me, this is the "holy grail" of studying. You feed it a few links, and it generates these incredibly fun, informative "Deep Dive" podcasts. I started listening to them on my daily commute, and honestly, I've never absorbed complex tech topics faster. - Source: dev.to / 3 months ago
