Building an autonomous Slack agent with OpenCode
Memory. I use Supermemory for this. Before, Pipa loaded context files and knew to update them. A memory tool adds teammate-like recall: goals, preferences, latest business state, and small details that should carry across runs. Good memory tools also know how to supersede and delete memories, which matters once the agent has more autonomy. - Source: dev.to / about 2 months ago
Build a Real-Time Voice RAG Agent for Your Documentation
We wire everything up with Vision Agents as the voice agent framework, Stream for WebRTC audio and video, OpenAI Realtime for speech in and speech out, Anam so the agent shows up as a face on the video, and Supermemory so answers come from search over your uploaded documents instead of guesswork. The code stays small and most of the behavior lives in one registered function that asks the memory store for relevant... - Source: dev.to / 3 months ago

How to Summarize PDFs Locally with Open-Source LLMs (No API, No Data Leaving Your Machine)
You just need a few summaries occasionally. Standing up Ollama, a model, and an extraction pipeline to summarize five PDFs is overkill. If privacy isn't the constraint, a free web tool does it in seconds — ChatPDF and NotebookLM if you don't mind an account, or PDFSummarizer.net if you want no sign-up and formats like EPUB/PPTX handled for you. One caveat that matters specifically because this article is about... - Source: dev.to / 20 days ago
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 / 2 months 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 / 3 months ago
How did I pass the AWS Certified Solutions Architect – 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 / 4 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 / 4 months ago
