You Asked. I Answered.
Here’s everything you need to know about Successible, the Accessibility Assistant from what to expect, how to use it, and how you can help shape this tool from the very beginning.
This isn’t an investor-backed project.
It’s powered by you — the people who believe accessibility should be easy, practical, and built for real-life use. Those who are done waiting for accessibility to be an afterthought.
If you’re here, you’re already part of the movement to make accessibility easier for everyone. Let’s get into the details.
1. Getting Started
After I sign up, what happens next?
You'll receive a welcome email with instructions to install the Successible Chrome extension. Once it's installed, open any platform you're already working in — Squarespace, Flodesk, Kajabi, and more — navigate to the page or email you want to check, and click "Run Accessibility Check." That's it.
Do I need to be technical or an accessibility expert?
No. Successible is built for creators, educators, marketers, and small-business owners—not developers. You’ll get plain-language guidance, clear suggestions, and no jargon.
What if I have questions before joining?
You can email: erin@mabelyq.com. I want you to feel fully informed and confident in your decision.
2. Subscription Details
Is there a free trial?
Yes! You can run 3 accessibility checks for free before your subscription starts — no credit card required. It's enough to see exactly what Successible catches and how it explains issues, so you can decide if it's the right fit.
How much does Successible cost?
Successible is $39/month, or $420/year if you'd like to save.
Can I cancel anytime?
Yep. No contracts, no hoops. If you need to cancel, you can do it anytime and you won't be charged again. Due to the digital nature of this product, we don't offer refunds on payments already processed — but you're never locked in going forward.
Can I use Successible for client work?
Yes. You can use your subscription as part of your services, audits, and builds for clients. If a client wants ongoing access to Successible themselves, they'll need their own subscription.
3. How the Tool Works
What is Successible exactly?
Successible isn’t an app you download from the App Store.
It’s a browser extension, similar to Grammarly, that sits inside the platforms creators already use such as Squarespace, Flodesk, Canva, or Thinkific.
When you're ready, click to run an accessibility check and Successible flags accessibility issues (missing alt text, poor color contrast, skipped headings, missing captions) and gives plain-language explanations so you know how to fix them instantly.
It works where the creator (YOU!) works. Not outside it.
How is Successible different from the WAVE extension?
They're both Chrome extensions that check for accessibility issues. But they're built for completely different people.
WAVE is a professional auditing tool built by an academic accessibility research organization. It's designed for developers and accessibility specialists who already know what they're looking at. When you run it, it overlays your page with technical flags, error codes, and WCAG references. If you don't already know what "WCAG 1.4.3 contrast failure" means or how to fix it inside your specific platform, the output doesn't give you much to work with. WAVE's own documentation even says it "facilitates human evaluation" — meaning it's a diagnostic that hands the interpretation back to an expert.
Successible is built for the person who isn't that expert. The plain language is part of it, but the bigger difference is where it runs. WAVE checks a finished webpage you navigate to. Successible works inside the tools you're already building in like: Flodesk, Squarespace, Kajabi, catching issues while you create, before anything goes live. It knows you're in Flodesk building an email, not just that a webpage exists somewhere.
WAVE is free, but free only helps if you can act on what it tells you. If the output requires a developer to interpret and fix, the cost just moved somewhere else.
Will this be available on common browsers?
Successible is currently available on Chrome. Support for additional browsers (Edge, Firefox, Safari) is on the roadmap.
Will it work on all web-based platforms?
Successible works on any platform built with standard web code — the kind most websites are made of. It's a Chrome extension, so as long as you're accessing your platform through Chrome, it can scan and flag issues. That includes Squarespace, Flodesk, Kajabi, Teachable, and more.
Some platforms — like Showit and Canva — work differently. Instead of building pages with standard code, they essentially "draw" content on the screen like a digital painting. Successible can't read what's painted, only what's coded. Our team is actively working on support for those platforms, and we'll let subscribers know as soon as it's ready.
Will this replace accessibility audits?
No. Successible is meant to complement audits, not replace them.
Think of it as an accessibility spell-checker that helps you maintain and apply best practices as you create content.
I'm curious how deep you intend the accessibility rules to go: keeping it lighter (color contrast, plain language) and selling it to business owners/generalist service providers, or go deeper (aria labels, skip-to-content, etc) and so it's useful for web designers/more technical folks?
Such a great question! The tool is staying focused on content creators first. These are the folks who’ve been left behind the most when it comes to accessibility, people creating inside platforms every day with no real guidance. I want them to feel confident and supported wherever they’re making content, without needing technical expertise. People like me!
The deeper, developer-level items (ARIA, skip links, etc.) really belong with the platforms themselves. Long-term, my plan is to build a team that can also consult directly with those platforms to make sure accessibility is baked in at the product level, while the tool gives creators the practical, real-time support they need.
So is it like having accessibility guidelines at your fingertips?
Yes. Successible surfaces up-to-date, practical guidance in context, so you can make informed, accurate decisions without wading through technical standards.
Will it work on design tools like Adobe?
Not in Phase 1. Those are being considered for future development. If you know anyone at Adobe, please connect me!
Will it help with accessible video content?
Yes, Successible flags missing video captions as part of its current checks.
Will it cover audio players (podcasts, Substack, embedded players)?
Yes, the intention is to support web-based audio players and flag key accessibility issues as part of ongoing development.
Will it eventually support social media content?
That’s the plan. We want to support accessible creation for platforms like Instagram, Facebook, etc. If you’re connected to a platform that wants to explore this, have them reach out.
Will it work with Office 365 tools like PowerPoint, Excel, and Word online?
If it’s web-based, ideally it would work inside those tools. I will have this part of testing process. Alternatively, it would be part of the longer term vision.
Will it be able to check code for accessibility issues?
Not in Phase 1. Successible is designed primarily for real-time, creator-friendly accessibility checks in visual platforms. More technical, code-level checks may be explored for future development.
How is this different from other browser accessibility checkers?
Most browser checkers are built for developers and generate technical reports. Successible is designed for creators, educators, and small business owners—providing real-time, plain-language guidance and easy, actionable fixes inside the platforms you already use. It focuses on understanding, not just error reporting.
4. Using Successible in Your Work
Can I use this for client work?
Yes. You can absolutely use your Charter Member access as part of your services, audits, and builds for clients.
Licensing-wise, what does that mean?
You can use the tool in your own workflow, including client projects.
If a client wants ongoing access to Successible themselves, they’ll need their own license once public plans are live.
Can I use it to run accessibility audits for clients?
Yes, as a supporting tool. It helps you check content against best practices more efficiently and consistently, but it is not a legal or full replacement for comprehensive audits.
5. Community, Sharing, and Support
Can I help promote Successible?
Yes, absolutely. A short promo video, swipe copy, and shareable visuals will be provided so you can easily post about the preview on LinkedIn or other platforms. Please reach out to me at admin@successible.co for more information.
Will there be an affiliate program?
Yes! an affiliate program is available. Reach out to erin at admin@successible.co for more details.
Aside from investing financially, how else can we support this?
Talk about it inside your communities and programs
Introduce potential partners or platforms
Join in testing and give honest feedback
Are you seeking feedback from disabled people with lived experience?
Yes. This is an easy answer as I’m a deafblind business owner. Feedback from disabled users (including those doing this work professionally) is a core part of how Successible will be built and improved
6. Installing Successible
Chrome showed a warning when I went to install, is it still okay to install?
When you go to install Successible from the Chrome Web Store, you might see one or two prompts that look a little alarming. I want to walk you through exactly what they mean so you can install with confidence.
Warning #1: "Proceed with caution. This extension is not trusted by Enhanced Safe Browsing."
This sounds scarier than it is. Chrome has a feature called Enhanced Safe Browsing that essentially keeps a reputation score for extensions, sort of like how a new restaurant doesn't have reviews yet, even if the food is great. Google only grants "trusted" status to extensions that have been around long enough and downloaded by enough people to build that track record.
Successible is brand new, so we haven't had time to rack up that history yet. This warning has nothing to do with whether the extension is safe. It simply means we're new to the neighborhood. As more people install and use Successible, this message will eventually disappear on its own.
You can safely click "Continue to install" to move forward.
Warning #2: "Add 'Successible'? It can: Read and change your data on api.successible.co"
This one is actually a sign that things are working exactly as they should. Chrome is required to show you a list of permissions every extension requests before you install it, think of it like reading the label before taking a new supplement.
What this permission means in plain English: Successible is allowed to communicate with its own backend to do things like run your accessibility checks and retrieve the rules it uses to flag issues.
Here's the important detail: the permission is limited specifically to our own system. Successible is not asking for access to your passwords, your other browser tabs, your email, or anything else on your computer. It's a targeted, narrow permission, which is exactly what you want to see.
You can safely click "Add extension" to finish the install.
