Making great content shouldn't depend on how much you can spend on software. Yet for most creators, the real cost of creating isn't the camera or the microphone. It's the stack of monthly subscriptions for a video editor, a design app, a photo developer, and an audio workstation, each one billing every month whether you used it or not. Today we're changing that. Creator Labs is a free suite of four professional creative apps, Stratos for video, Valen for design, Calyx for photo, and Aether for audio, that run right in your browser and sign in with your Whistlr account. No credit card, no watermark, no downloads. This guide covers what Creator Labs is, what each app can do, how your files stay private on your own computer, how it connects to Whistlr, and how to start making your best work today.
If you've been following PX News, you know we've spent the past year building the business side of being a creator: Creator Studio for analytics, streaming, and earnings, the Creator Wallet for getting paid, and Vault and Tips for direct fan support. Creator Labs fills in the other half of the picture. Those tools help you run a creator business. Creator Labs helps you make the thing your audience comes for in the first place.
What Is Creator Labs?
Creator Labs is ETAPX's free, browser-based creative suite for creators. It brings four full creative applications into one home, so you can edit video, design thumbnails and posters, develop and retouch photos, and record and mix audio, all from a single browser tab. Our tagline for it is simple: create like a pro, pay nothing.
Each app in the suite is a native application built in Rust and compiled to WebAssembly, the technology that lets demanding software run at near-native speed inside a modern browser. That matters, because "browser editor" has usually meant "lightweight editor." Creator Labs isn't a set of simplified web toys. It's four serious tools with multitrack timelines, real layer stacks, raw photo development, and a full mixer, built to handle the kind of work creators actually ship.
Creator Labs runs on the same account as Whistlr. If you already have a Whistlr account, you already have a Creator Labs account. Sign in once, and you can move between video, design, photo, and audio without starting over, then post what you make straight to your Whistlr profile.
"Every creator we talk to is paying for tools before they've earned a dollar from their content. That's backwards. The people with the best ideas shouldn't be the ones with the biggest software budget. Creator Labs puts professional video, design, photo, and audio tools in front of anyone with a Whistlr account, for free, so the only thing standing between a creator and great work is the work itself."
— AJ, Founder & CEO, ETAPX
Why We're Giving It Away for Free
We get asked this a lot, so here's the honest answer. Whistlr does well when creators do well. When creators make better content, audiences stay longer, communities grow stronger, and the whole platform gets better for everyone. The fastest way to raise the quality of what people make is to remove the paywall in front of the tools they need to make it.
Paid creative software also creates a quiet barrier that keeps a lot of talented people on the sidelines. A student with a phone full of footage, a musician recording on a laptop, a small business owner who needs a product photo to look right: these are exactly the creators who benefit most from professional tools and who are least able to pay for four separate subscriptions. Creator Labs is built for them as much as it's built for full-time creators.
And because Creator Labs connects to Whistlr, the path from making something to earning from it is short. You create in Creator Labs, share to Whistlr, and get paid for what you make through the monetization tools creators already use, like Gems, Tips, subscriptions, Vault, and Storefronts. Free tools on one side, real income on the other, and nothing in between asking for your card number.
What "Free" Actually Means Here
- No credit card: You don't enter payment details to sign up or to use any of the four apps.
- No watermark: Your exports are yours. Videos, images, photos, and mixes come out clean, without a Creator Labs logo stamped on them.
- No downloads: Everything runs in your browser. There's nothing to install and no 10 GB installer eating your drive.
- No paywall on pro features: You get the professional tools from day one. There's no "upgrade to unlock color grading" moment waiting halfway through a project.
Meet the Suite: Four Pro Apps in One Browser Tab
Creator Labs is built around the four kinds of work almost every creator does at some point: video, design, photo, and audio. Each app has its own focus, its own color, and its own deep toolset, and they all share one account, one file library, and one home screen.
Stratos: Edit, Color, and Mix Video
Stratos is the video editor in Creator Labs, and it's built for creators who want real control over their cuts. Edit on a multitrack timeline with ripple, roll, slip, and slide edits, nested sequences, markers, and a source monitor, the same editing vocabulary professional editors rely on every day. Bring in clips straight from your computer and stack video, audio, titles, and images across as many tracks as the project needs.
When the cut is locked, Stratos handles the finishing. Grade your footage with basic color correction, curves, color wheels, and HSL controls, and check your work on waveform, vectorscope, and histogram scopes so your skin tones and exposure hold up on every screen. Add effects and keyframes, build titles and captions, and export your finished video without a watermark. Stratos opens common formats like MP4, MOV, MKV, and WebM, and it reads interchange files such as XML, EDL, and OTIO along with SRT and VTT caption files, so projects and subtitles from other workflows come with you.
- Best for: Whistlr Minis, vlogs, YouTube-length videos, trailers, short documentaries, music videos, and stream highlight reels.
- Standout tools: Professional trim edits, nested sequences, color scopes, keyframed effects, and caption support.
Valen: Layers, Masks, Type, and Real PSD Files
Valen is the design and image-editing app, and it's where thumbnails, posters, cover art, flyers, banners, and composites come together. It works with layers, groups, masks, adjustment layers, blend modes, and layer styles, and it opens and saves real PSD files, so a design you started elsewhere, or one a collaborator sends you, opens with its layers intact instead of as a flattened image.
Valen also handles live type and vector shapes. Set text that stays editable, draw with pen and shape tools, and build graphics that stay sharp at any size, which matters when the same artwork has to work as a tiny profile thumbnail and a full-screen cover. Brushes, retouching tools, and support for formats including PNG, JPEG, WebP, TIFF, and SVG round it out. Valen can even run plug-ins, so its toolset can grow over time.
- Best for: Video thumbnails, channel art, event posters, merch mockups, memes, album covers, and social graphics.
- Standout tools: Full PSD support, adjustment layers, layer styles, live type, and vector shapes.
Calyx: Photo Library and Raw Development
Calyx is the photo app, built for creators who shoot on a real camera or who want their phone photos to look their best. It combines a photo library for organizing your shots with a non-destructive raw developer for editing them. Develop raw files from your camera with exposure, tone curves, a color mixer, and color grading, and because every edit is non-destructive, your original file is never changed. You can always go back.
Calyx reads raw files from most major camera makers, including Canon CR2 and CR3, Nikon NEF, Sony ARW, Fujifilm RAF, Panasonic RW2, and DNG, with support expanding camera by camera, alongside everyday JPEG, PNG, and TIFF files. Masking lets you select a subject, the sky, a brush stroke, or a gradient and adjust just that part of the image. Presets and before-and-after views keep you moving quickly through a full shoot, and when you're done you can export full-resolution JPEG, PNG, or TIFF files ready to post.
- Best for: Portraits, product photography, travel and landscape shots, event coverage, and consistent feed aesthetics.
- Standout tools: Raw development, subject and sky masking, presets, and non-destructive editing.
Aether: Record, Edit, and Mix Audio
Aether is a complete digital audio workstation that runs in your browser. Record, arrange, and edit audio and MIDI across as many tracks as you need, with markers, rulers, and a transport that feels like a real studio. Whether you're producing beats, recording vocals, cutting a podcast, or building a soundtrack for your next video, Aether gives you a proper multitrack environment to do it in.
When it's time to mix, Aether's full mixer gives you inserts, sends, buses, and automation, plus built-in plug-ins for EQ, dynamics, reverb, delay, and more. Balance your song, automate your fades and effects, and bounce your final mix to a file on your computer. Aether opens WAV, MP3, AAC, FLAC, AIFF, OGG, and MIDI files, so voice memos, samples, stems, and MIDI sketches all drop right in.
- Best for: Beat-making, songwriting, podcasts, voiceovers, sound design, and video soundtracks.
- Standout tools: Multitrack audio and MIDI, a full mixer, automation, built-in effects, and bouncing.
"I was paying for three different apps just to put out one video a week: one to cut it, one for the thumbnail, one to clean up my voiceover. Now I do all three in one tab. The thumbnail work in Valen surprised me the most. I opened an old PSD from a designer friend and every layer was still there."
— Marcus, gaming and commentary creator on Whistlr
Your Files Stay on Your Computer
One of the biggest decisions we made with Creator Labs is also one of the least visible: your files stay on your computer. The apps read and write files through your browser's File System Access feature, which means your raw footage, PSDs, raw photos, and recordings are opened straight from your drive and saved back to it. Nothing gets uploaded. Your unreleased work isn't sitting on someone else's server waiting to be processed.
That local-first approach has real benefits beyond privacy. There's no waiting for a 4 GB video file to upload before you can start editing. There's no storage cap to run into halfway through a project. And your files remain normal files in normal folders, so you can back them up, move them, or open them in other tools whenever you like. Creator Labs works with your files instead of locking them inside a proprietary cloud.
Link a Folder and Let Saving Take Care of Itself
Creator Labs makes saving almost invisible. You can export to any folder you want, or connect one folder as your workspace, and everything you make lands there on its own. Once a document is linked to a file on your computer, every change you make is written to that file as you work, so the version on your drive is always the latest. The Files page shows everything you've opened from or saved to your computer, with the app, size, and last-modified time for each file, and you can drop new files anywhere on the page to add them.
If a document doesn't have a file yet, or your browser needs your permission to write to it, Creator Labs keeps your latest changes as a draft in your browser, and the next time you open the studio it brings that draft right back. The status indicator always tells you where your work stands: saved to your computer, saving now, kept in this browser only, or waiting for permission.
- Saved: The file on your computer has your latest changes.
- Unsaved: Your work is safe as a draft in this browser and will reopen on your next visit.
- Needs permission: The document is linked to a file, and your browser is waiting for you to allow Creator Labs to write to it.
A quick browser note: local saving works best in Chrome, Edge, and other Chromium-based browsers, which fully support writing files back to your computer. In browsers with more limited support, your saves come down as regular downloads instead of being written back to the original file.
"We built Creator Labs so the browser does the work a desktop app would do, without asking creators to hand over their files. Each app is a native engine compiled to WebAssembly, so it runs fast in a tab, and it reads and writes your files where they already live. Your footage never leaves your computer unless you decide to post it."
— John Ridge, CTO, ETAPX
One Account, One Home Screen, Four Apps
Creator Labs is designed to feel like one product, not four separate websites. When you sign in, you land on a home screen with your recent files, quick-start tasks, and a create box where you can simply describe what you want to make. Type something like "cut my vlog footage into a short," "design a thumbnail for my new video," "brighten my portrait shoot," or "mix my podcast episode," and Creator Labs picks the right app for the job. Drop a file in instead, and it opens in the app built for that file type: video in Stratos, PSDs and images in Valen, raw photos in Calyx, and audio in Aether.
Because the suite shares one account and one file library, moving between apps doesn't mean starting over. Develop a photo in Calyx, take it into Valen to build a thumbnail around it, then drop that thumbnail into your Stratos timeline as an end card, with the soundtrack you mixed in Aether underneath it all. That's a full content workflow without a single subscription or a single upload.
Creator Labs and Whistlr Work Together
Creator Labs is built to sit alongside Whistlr: make it here, post it there. Your Whistlr account signs you straight in, with Apple, Google, or email, and you can post videos, photos, and tracks straight to your Whistlr profile. If you're new to Whistlr, signing up takes a minute, and that one account then works across Whistlr, Creator Labs, and the rest of the Whistlr Network.
Here's how Creator Labs fits with the other creator tools in the Whistlr ecosystem:
- Creator Labs: Where you make your content, with pro video, design, photo, and audio apps in the browser.
- Whistlr: Where you share it, build your community, and get discovered through the feed, Search, and Circles.
- Creator Studio: Where you run the business side, with analytics, scheduling, live streaming, and earnings in one dashboard.
- Whistlr for Business: Where creators and brands grow with advertising and partnership tools.
Who Creator Labs Is For
We built Creator Labs for anyone who makes things, and it looks a little different depending on where you are in your creative journey.
- New creators: Start with professional tools from day one instead of outgrowing a basic app in six months. Learn real editing, design, and mixing skills that carry forward as you grow.
- Growing creators: Drop the subscriptions and put that money back into gear, collaborators, or your channel. Keep a consistent look across your thumbnails, photos, and videos with one connected toolset.
- Musicians and podcasters: Record, edit, and mix in Aether, design your cover art in Valen, and cut a visualizer or promo clip in Stratos.
- Photographers: Organize and develop full shoots in Calyx, then build portfolio posts and promotional graphics in Valen.
- Students and educators: Teach and learn professional creative workflows on any computer with a modern browser, with no licenses to manage and nothing to install.
- Small businesses: Make product photos, promotional videos, menus, and social graphics in-house, then sell through your Whistlr Storefront.
How to Get Started With Creator Labs
Getting started takes a couple of minutes, and none of it costs anything.
- Open Creator Labs in your browser. For the best experience, use Chrome, Edge, or another Chromium-based browser on a laptop or desktop computer.
- Sign in with your Whistlr account. Use Apple, Google, or email, the same way you sign in to Whistlr. New to Whistlr? Create your free account first, and it works in Creator Labs right away.
- Connect a folder. Pick a folder on your computer as your workspace so everything you make saves there automatically. You can skip this and choose where to save each file instead.
- Describe what you want to make, or drop in a file. Type your idea into the create box or drag in a clip, PSD, raw photo, or voice memo, and Creator Labs opens the right app.
- Create, then export. Edit with the full toolset and export your finished work, with no watermark, to any folder you like.
- Share to Whistlr and get paid. Post your finished video, photo, or track to your Whistlr profile and turn on the monetization tools that fit your audience.
Tips for Getting the Most Out of Creator Labs
The tools are powerful on their own, but a few habits will help you work faster and keep your projects organized from the start.
- Make one folder per project. Connect a project folder as your workspace so footage, artwork, photos, and mixes for one release all live together and save automatically.
- Grant file permission when asked. When your browser asks to let Creator Labs save to a file, allow it, so your work is written straight to your drive instead of waiting as a browser draft.
- Check your scopes, not just your screen. In Stratos, use the waveform and vectorscope to make sure your color holds up on phones, laptops, and TVs, not just your monitor.
- Keep your text live. In Valen, leave titles as editable type layers so you can update a thumbnail series with new episode numbers in seconds.
- Build presets for your look. In Calyx, save your favorite edits as presets so every photo you post feels like part of the same feed.
- Bounce stems for video. In Aether, bounce your music and voice separately so you can balance them against each other later in your Stratos timeline.
- Design for the feed. Remember that most of your audience watches on a phone. Frame, caption, and size your content for vertical viewing first.
"Creator Labs completes the loop we've been building toward. Creators make their content in Creator Labs, share it on Whistlr, and run their business in Creator Studio, all on one account. Every step from first idea to first payout now has a real tool behind it, and the creative step doesn't cost a thing."
— Renata Osei, VP of Product, ETAPX
