Gemini Notebook
Google's source-grounded research notebook, formerly NotebookLM: add your documents and get cited answers, summaries and Audio Overviews.
What Gemini Notebook does
Gemini Notebook is Google's research assistant that works from the sources you give it. Until July 2026 it was called NotebookLM; Google says it is the same product and existing notebooks remain available. You create a notebook, add sources, and ask questions. Answers draw on those sources and include inline citations, which makes it easier to check where a claim came from.
Sources can be PDFs, Google Docs, Slides and Sheets, Word and PowerPoint files, text, Markdown and CSV files, web pages, public YouTube videos, audio files, images, ePub files and Play Books. The help center sets a limit of 500,000 words or 200MB per source, and free users can add up to 50 sources per notebook.
From those sources it can produce podcast-style Audio Overviews, Video Overviews, reports, slides, infographics, flashcards and quizzes. Deep Research and Source Discovery look for new material to add. Personal accounts can share a notebook publicly.
It runs on the web and in iOS and Android apps. The standalone plan is free; Google AI Plus, Pro and Ultra subscriptions raise usage limits and source caps, and organizations get it through Google Workspace, Workspace for Education or Google Cloud. It suits students, researchers, analysts and anyone who needs to work through a pile of documents and wants answers tied to them.
- Asking questions across a set of papers, reports or class notes with cited answers.
- Turning source material into an Audio Overview to listen to.
- Making flashcards and quizzes from course material.
- Building a public notebook of help-center articles for quick answers.
Who should use it
- Students and researchers working through many documents.
- Analysts and teams who want answers tied to their own sources.
Who should look elsewhere
- Questions that need general web knowledge beyond the sources you add.
- Developers who need a documented API; the consumer pages do not describe one.
Strengths
- Answers cite the uploaded sources inline.
- Accepts many source types, including YouTube videos, audio, images and Google Workspace files.
- Free plan with up to 50 sources per notebook.
- Workspace and Education data is not used for model training or human review.
Limitations
- Free users are limited to 50 sources per notebook and standard usage limits.
- Google AI Plus, Pro and Ultra plans are available only in some regions.
- Deleted notebooks cannot be recovered.
- Public sharing works only for consumer accounts, and YouTube sources must be public videos.
Privacy notes
Google says content from personal accounts is not used for training unless you submit feedback, and feedback can be reviewed by trained human reviewers. For Workspace and Education accounts, uploads, queries and responses are not reviewed by humans or used to train AI models, even when feedback is given.

Agent Reach is a Python command-line tool that prepares an AI agent to read and search sites that are awkward to reach from a script, including Twitter/X, Reddit, YouTube, Bilibili, XiaoHongShu and GitHub. It leaves the actual reading to other tools. For each platform it picks an upstream project (Jina Reader for web pages, yt-dlp for YouTube, gh for GitHub, feedparser for RSS, twitter-cli and OpenCLI for social sites), installs it, checks that it works and gives the agent a SKILL.md file describing what to call. Every platform has an ordered list of backends, and when one breaks the maintainers move the next one up. The README cites June 2026, when Bilibili blocked yt-dlp and the tool switched to bili-cli. Running agent-reach doctor shows which channels work and which backend each is using. Web pages, YouTube, RSS, public GitHub repositories, V2EX and basic Bilibili search need no setup. Twitter, Reddit, XiaoHongShu, Facebook and Instagram need a logged-in session, either from cookies you export by hand or through OpenCLI reusing your desktop Chrome login. The main README is in Chinese; English, Japanese and Korean versions sit in the docs folder.

oMLX is a local LLM inference server for Macs with Apple Silicon, built on MLX and managed from a menu bar app. It exposes OpenAI-compatible and Anthropic-compatible endpoints, so existing clients can connect to http://localhost:8000/v1 without code changes. Its main idea is a two-tier KV cache. Frequently used cache blocks stay in RAM, and when that hot tier fills up, blocks are offloaded to the SSD in safetensors format so they can be reused instead of recomputed. The author pitches this at long coding sessions with tools such as Claude Code. Concurrent requests go through continuous batching using mlx-lm's BatchGenerator. The server loads text LLMs, vision-language models, OCR models, embeddings and rerankers. Several models can stay loaded at once, with least-recently-used eviction, pinning and a per-model idle timeout. A web admin dashboard at /admin covers monitoring, model management, chat and benchmarks. Source builds also include an experimental mode that splits one model across several Macs. You can install it as a .dmg from GitHub Releases, through Homebrew, or from source, and it is licensed under Apache-2.0.

iFixAi is an open-source Python tool that audits AI agents and models by running a set of test inspections and returning an A to F grade with a written report. The free engine has 60 inspections. The grade comes from five core pillars: fabrication, manipulation, deception, unpredictability and opacity. Another 28 inspections from twenty premium categories are included and reported on their own, outside the grade. A grade counts as citable only when a judge model from a different vendor scores the run, so a full audit needs two API keys. You can test a bare model through providers such as Anthropic, OpenAI, Gemini, Azure, Bedrock and OpenRouter, or point the tool at your own agent's OpenAI-compatible HTTP endpoint. There are three ways to run it: a setup wizard, a CLI with explicit flags for CI, or a plugin for Claude Code and Codex, with a scaffolded /ifixai-skill command for other agents. Reports land as JSON and Markdown in ./ifixai-results/. The README estimates judge costs for a full run with a Sonnet judge at roughly $12 to $18, billed by the provider. The company also sells iFixAi Pro, a paid audit service with up to 400 inspections. Telemetry is on by default outside CI and can be switched off.

AI Engineering from Scratch is a free, MIT-licensed course on GitHub that teaches how AI systems work by having you write each piece yourself, starting with linear algebra and ending with multi-agent systems and production infrastructure. The material is split into 20 phases and 523 lessons, with code in Python, TypeScript, Rust and Julia. Each lesson folder holds a written explanation, runnable code and an outputs directory. The pattern is to build an algorithm such as backpropagation, a tokenizer, attention or an agent loop from plain math first, and only then run the same idea through a library like PyTorch or scikit-learn. Lessons end with something you keep: a prompt, a SKILL.md file, an agent or an MCP server. The repository holds 396 skills and 99 prompts produced this way, plus a script that copies them into an agent's skills folder. There are three ways to follow it. You can read lessons on the website with no setup, clone the repository and run the code locally, or install the course's tutor skills into a coding agent such as Claude Code or Codex. Those skills run a placement quiz, write a study plan to LEARNING.md and teach one lesson per session. Separate tracks prepare for the four Claude certification exams and the MCP Associate exam; the README says these are independent and not affiliated with the exam bodies.
