Gemma Gem is an open-source Chrome extension that runs Google's Gemma 4 language model entirely in your browser using WebGPU — no API keys, no server, no data leaving your device. Install the extension, wait for the one-time model download (500MB for the efficient 2B variant, 1.5GB for the larger 4B), and you have a fully private AI assistant that can read web pages, fill forms, take screenshots, and execute JavaScript. The extension uses Hugging Face Transformers.js with ONNX-quantized versions of Gemma 4's E2B and E4B variants, making the model small enough to run in a browser tab without throttling GPU memory. Gemma 4's strong efficiency profile — particularly its per-layer attention architecture — makes it a natural fit for WebGPU's memory constraints compared to older models at similar parameter counts. What makes Gemma Gem interesting beyond the cool factor: it's a glimpse at what fully private, zero-latency browser-native AI looks like. There's no round-trip to a server, no API billing, no rate limits. On a mid-range MacBook M3 or gaming GPU, inference is fast enough to be genuinely useful. The trade-off is capability — Gemma 4 E2B is a 2B parameter model, not Claude or GPT-5, but for summarization, form-filling, and basic Q&A it holds its own.

Notebooks in Gemini
Google brings project-scoped AI workspaces to Gemini — chats, docs, files in one space

Google has launched Notebooks in Gemini, a new organizational layer that groups related chats, files, and project context into a single persistent workspace. Unlike standard Gemini conversations that exist in isolation, Notebooks let users create project-scoped containers — similar in spirit to Claude's Projects feature — where AI context, uploaded documents, and conversation history persist and accumulate over time. The feature integrates with Google Workspace, allowing users to attach Google Docs, Sheets, Drive files, and Gmail threads directly to a Notebook. Gemini can then be queried across all attached materials in a unified way, making it useful for long-running research, client projects, or any work that spans multiple sessions and document types. Notebooks debuted at #2 on Product Hunt with 181 upvotes on launch day. This positions Gemini more directly against Claude's Projects and ChatGPT's memory-augmented workspaces. For Google Workspace users in particular, the tight Drive and Docs integration gives Notebooks a material advantage — it's the only AI workspace with native access to the full Google productivity stack. Enterprise buyers who've already committed to Workspace will find the feature immediately useful without any additional setup.
Reviewer scorecard
“WebGPU inference in a browser extension is a technical achievement worth shipping just to see what's possible. The ONNX quantization pipeline here is clean and reusable. I'd fork this immediately for any project needing fully offline browser AI.”
“The Google Workspace integration is the story here — native Drive, Docs, and Gmail context inside an AI workspace is something Claude Projects and ChatGPT can't match out of the box. For teams already deep in Google's ecosystem, this is a no-brainer upgrade to their AI workflow.”
“A 2B parameter model running in a browser tab via ONNX quantization is impressive engineering, but the actual capability is limited. For anything that requires reasoning, current knowledge, or multi-step tasks, you'll hit a wall fast. Fun demo, not a daily driver.”
“Claude Projects and Notion AI already do this better in many respects. Google has a history of launching polished features and then abandoning them — Stadia, Inbox by Gmail — so long-term commitment is a real concern. The feature is also locked behind Gemini Advanced for power usage.”
“On-device browser AI is the privacy endgame. When models are good enough to run locally in a browser tab, the cloud AI industry faces a genuine disruption threat. Gemma Gem is two years early to the party, but the party is coming.”
“Persistent, project-scoped AI workspaces are the natural evolution of how knowledge workers will interact with AI — not ephemeral chats but living project brains. Google pushing Notebooks mainstream normalizes this interaction model and accelerates adoption across the massive Workspace install base.”
“The idea of an AI that reads web pages with me and answers questions without any privacy concerns is huge for creative research. I'm tired of pasting article excerpts into ChatGPT. This should be the default browser experience.”
“For creative projects spanning multiple briefs, reference files, and iteration rounds, having a Notebook that holds all of it in one AI-queryable space is a real quality-of-life improvement. Especially useful for agencies running multiple client projects simultaneously in Google Docs.”
