NotebookLM Now Automatically Labels and Categorizes Your Research Sources

If you rely on NotebookLM for research, you know the struggle: sources pile up fast, and manually sorting through ten or more entries is a chore. Google has finally addressed this pain point with a new NotebookLM auto-label feature that organizes your research sources for you. As a result, you can spend less time scrolling and more time actually thinking.

The AI-powered research assistant, built on Gemini, now automatically detects when your notebook contains five or more sources. Once that threshold is crossed, it reads the content of each source and groups related items together. Labels are then assigned based on topic, making your research source organization smoother than ever.

How Does NotebookLM Auto-Label Work?

When your notebook reaches the five-source mark, NotebookLM scans the material and clusters similar entries. It then applies labels to those clusters—like “market trends” or “case studies”—based on the content. If a single source touches multiple subjects, the system can assign more than one label. This flexibility ensures your organization stays accurate without being rigid.

You still have full control over the results. Labels can be renamed, reorganized, or even spiced up with emojis. If the AI’s categorization doesn’t match your needs, you can override it and assign your own label. This means the NotebookLM auto-label feature is both intelligent and customizable.

Building on this, Google is considering expanding the feature to improve how outputs are organized, though that enhancement hasn’t been confirmed yet. For now, the auto-labeling alone cuts down the time you waste digging through unorganized piles of material.

Notebook Sharing Gets a Major Upgrade

Another long-standing frustration—sharing notebooks with groups—has also been fixed. Previously, you had to enter each email address individually, which was tedious for large teams. Now, you can paste an entire list of email addresses at once, and NotebookLM automatically parses and identifies the recipients. This update makes Google NotebookLM update especially valuable for collaborative projects.

Both features are rolling out now and should reach all users shortly. As Google deepens the integration between NotebookLM and Gemini, the tool recently arrived inside Gemini Notebooks, and notebook projects are now free for all Gemini users on the web. This gives more people a reason to make it part of their daily workflow.

Why This Matters for Researchers and Students

For academics, journalists, and anyone who juggles multiple sources, the NotebookLM auto-label feature is a game-changer—without using that cliché word. It reduces manual sorting and lets you focus on analysis. Instead of fighting with folders, you let AI handle the heavy lifting.

However, the tool doesn’t take away your control. You can always tweak labels or reorganize groups. This balance between automation and customization is what makes NotebookLM stand out among AI research assistants. If you’re looking for a way to streamline your research, start by exploring how using NotebookLM for research can boost your productivity.

In addition, the ability to share notebooks with multiple people at once simplifies team projects. You no longer need to send individual invites—just copy and paste your list, tap send, and everyone gets access. This is a small change that makes a big difference for group work.

What’s Next for NotebookLM?

Google continues to refine NotebookLM, and the auto-label feature is just one step. With the Gemini integration expanding, we can expect more intelligent features in the future. For now, the focus is on making research source organization effortless.

If you haven’t tried NotebookLM yet, now is a great time. The tool is free, and the new updates make it even more user-friendly. Check out our guide on best AI research tools to see how NotebookLM compares to other options.

Ultimately, the NotebookLM auto-label feature saves you time and mental energy. Whether you’re writing a thesis, preparing a business report, or just curious about a topic, let AI organize your sources while you focus on the big picture.

Databricks wanted $1 billion. Investors offered $15 billion. Here’s what happened next.

Published

on

Databricks raises $5B

The leak that changed everything

It started with a single news article. Not a product launch, not a customer win — just a report from The Information that Databricks was raising money. That was enough to set off a chain reaction CEO Ali Ghodsi never anticipated.

“We wanted to raise $1 billion, but then The Information printed this article saying that Databricks is doing a big fundraise,” Ghodsi told TechCrunch. “We were heads down with our conference, and we were not actually at all focused on fundraising.”

The timing couldn’t have been worse. Databricks was in the middle of its annual user conference in June, and Ghodsi’s phone wouldn’t stop buzzing. “My phone blew up. It was like the worst timing for us because we were busy with our conference,” he recalled.

But here’s the thing about having too many investors pounding on your door — it’s a pretty good problem to have. What started as a modest $1 billion target quickly snowballed into something far bigger. “The interest level was just insane. Just from this select group of investors that we looked at, there was $15 billion of interest,” Ghodsi said.

From $1 billion to $5 billion: how the round grew

When you’ve got that much demand, telling longtime backers they can’t get in is a quick way to burn bridges. So Databricks made a pragmatic call: issue more stock. In July, the company announced it had closed a new round at a $188 billion valuation, though it kept the exact amount under wraps at the time.

On Thursday, the full picture emerged. Databricks raised $5 billion at a valuation that ticked up to a clean $190 billion. The round was led by Coatue, with participation from Blackstone, MGX, T. Rowe Price accounts, and newcomer Sixth Street Growth — the firm founded by former Goldman Sachs chief investment officer Alan Waxman. All told, about two dozen VCs got a piece of the deal.

Why investors were so eager

The answer is simple: Databricks looks like a sure bet. Ghodsi says the company has hit $7 billion in annualized run-rate revenue, growing at 80% and already cash-flow positive. Its core cloud data warehouse product alone generates $1.5 billion of that run-rate and is still expanding at 100% year-over-year.

Then there’s the AI angle. Lakebase, the company’s database for AI agents launched in June 2025, has already reached a $100 million revenue run-rate. And Genie, its AI chatbot for business analysis, is — in Ghodsi’s words — “insanely popular.”

Why raise more when the business is thriving?

That’s the obvious question. Databricks had already pulled in $20 billion over the past 20 months. But AI doesn’t come cheap.

“AI research is very expensive,” Ghodsi said, noting the company employs a 100-person AI research team. Databricks also has multi-billion dollar cloud commitments with all three major hyperscalers — AWS, Azure, and Google Cloud.

On top of that, Databricks is on an acquisition spree. This week it snapped up Electric, the company behind the lightweight Postgres database PGlite. In June it bought AI cybersecurity firm Panther, and in March it acquired two more startups. “We do a lot of M&A,” Ghodsi said simply.

The new math of mega-rounds

There was a time when a $1 billion raise was considered massive — a headline-grabbing feat that took months of courting investors. In today’s AI gold rush, that number barely moves the needle. Startups are walking out of the gate with billion-dollar seed rounds.

Databricks’ private fundraising has become something of a running joke in Silicon Valley. When the company announced this round last month, observers quipped online that it had raised so many times it was running out of letters of the alphabet to name the rounds.

What’s next for Databricks?

Ghodsi told CNBC he still wants to take the company public eventually. With this many investors on the cap table, all of whom will want an exit at some point, he doesn’t have much choice.

But for now, the focus is on investing in AI — and doing it out of the public eye. Given the expenses involved, staying private a while longer makes sense. And when you can command $15 billion in instant interest on your own terms, why rush?

Anti-surveillance clothing is getting cheaper, but don’t expect an invisibility cloak

anti-surveillance clothing

Privacy fashion moves from art school to the street

Anti-surveillance clothing is starting to look less like an art-school experiment and more like something you could actually wear outside. Shirts designed to confuse facial recognition systems now cost about as much as ordinary streetwear. But buying one won’t make you disappear.

Designers are using face-like prints, unusual cuts and infrared lights to interfere with computer vision, according to The Guardian. These techniques target specific weaknesses, so their success depends on what happens to be watching you.

How can clothing confuse a camera?

Adversarial clothing takes advantage of the shortcuts software uses to identify people and objects. Urban Privacy‘s Faception designs scatter fake faces across the fabric, giving an algorithm more visual noise to process.

Cap_able, meanwhile, uses knitted patterns created with AI. The company says versions of the YOLO object-detection system have mistaken its designs for animals or small figures instead of identifying the wearer as a person. It’s an amusing result, but fooling one model doesn’t guarantee the same trick will work elsewhere.

Infrared tricks for night vision

Urban Privacy’s experimental Urban Ghost coat tries a different approach. Infrared LEDs around its hood are intended to overwhelm compatible night-vision cameras. Regular cameras and other surveillance systems may remain completely unimpressed.

How affordable is privacy fashion?

Urban Privacy lists Faception Reloaded T-shirts from €35, sweatshirts from €59 and hoodies from €65. At those prices, anti-surveillance clothing isn’t reserved for wealthy privacy enthusiasts or gallery mannequins.

Cap_able remains considerably more expensive. Its knitted crop tops start at €560, while a hoodie costs €620. That puts the collection firmly in wearable-art territory, but the cheaper Urban Privacy garments show how quickly the idea is filtering down. You can now test an adversarial pattern without making your bank account unrecognizable too.

Why shouldn’t you trust it completely?

Controlled testing against one object-detection model can’t prove a garment will defeat facial recognition in public. Lighting and camera position can alter the result, while newer software may learn to ignore patterns that once caused trouble. Researcher Jennifer Bell also told The Guardian that these products haven’t undergone independent real-world testing.

That makes adversarial clothing more convincing as protest than protection. Wearing one makes a clear statement about surveillance and may inconvenience certain systems along the way. Just don’t treat a patterned hoodie as an anonymity switch. Until these garments face broader independent testing, assume the camera can still see you.

Google’s Gemini is about to let you fine-tune its voice. Here’s what’s coming

Published

Gemini voice customization

Google is handing you the mixing board for Gemini’s voice

For months, Google has been quietly pushing Gemini to sound less like a robot reading a script and more like, well, a person. The next step? Letting you dial in exactly how that person talks.

Fresh code pulled from the latest Google app beta (version 17.41.12) points to a new Gemini voice customization panel. Instead of picking from a handful of preset personalities, you’d get four separate sliders: Energy, Formality, Warmth, and Speed. Each one runs from Low to High (or Slow to Fast for speed).

That’s a meaningful departure from the current setup, where your choices are essentially limited to the voices Google cooked up for you.

What the new controls actually do

The feature hasn’t been announced yet, so we’re working from what’s visible in the code. Android Authority’s APK Insights team dug into the strings and found a dedicated “Customize” section tucked inside Gemini’s voice settings.

Here’s the breakdown of what you’d be able to adjust:

  • Energy: Low, Medium, High
  • Formality: Low, Medium, High
  • Warmth: Low, Medium, High
  • Speed: Slow, Normal, Fast

These aren’t meant to replace the existing voices. Rather, they’d layer on top of them. So you could pick a voice you like and then tweak its delivery to match your mood or use case — say, a brisk, formal tone for work queries and a slower, warmer one for casual chats.

The settings are expected to carry across both Gemini Live and the standard chat interface, which means you won’t have to reconfigure things depending on where you’re talking.

Why this matters after the Google I/O refresh

This discovery lands right after Google overhauled the voice picker following I/O. The old carousel interface is gone, replaced with a cleaner list. Two new voices — Flare and Glow — joined the lineup, bumping out Nova and Lyra.

The current roster now stands at ten voices: Ursa, Vega, Pegasus, Dipper, Eclipse, Capella, Orbit, Orion, Flare, and Glow.

Interesting detail: Google also stripped away the personality labels that used to describe each voice, things like “Calm” or “Bright.” Now you’re left to judge purely by ear. That move makes more sense in hindsight — if users are about to get granular controls, the preset descriptions become less relevant.

The interface is getting a facelift too

Alongside the voice changes, the update refreshes Gemini’s icons — slimmer, more modern takes on the microphone, camera, gallery, file upload, video, screen sharing, and Gemini Live buttons. These visual tweaks are rolling out via a server-side update alongside Gemini version 1.0.913571982.

Google isn’t the only one tuning voices

This push toward personalization fits a broader trend. At Google I/O, the company said regional dialects are on the roadmap for Gemini. Voice customization slots neatly into that effort to make AI feel less generic.

Apple is heading the same direction. Apple‘s iOS 27 gives Siri AI similar controls — Pace and Expressivity — and those preferences extend across Maps and Safari.

The subtext here is clear: the AI race isn’t just about what assistants can do anymore. It’s about how they sound while doing it. Tone, warmth, and cadence are becoming competitive battlegrounds.

What to expect next

None of this is official yet. Code in a beta doesn’t guarantee a public rollout, and Google could tweak the feature before it ships. But the trajectory is obvious.

If this lands as expected, you’ll soon be able to shape Gemini’s voice to fit your ear — not the other way around. For anyone who’s ever winced at a too-chipper assistant or struggled to follow a machine-gun-fast response, that’s a genuinely useful upgrade.

Keep an eye on the Google app beta updates in the coming weeks. And if you’re curious about where Gemini Live is headed, our Gemini Live features guide covers what’s already available. For more on the broader shift, check out how Siri’s new voice controls compare.
