About Speechius and Mainstack.co

In their own words, as submitted to SaaSHub.

Speechius
Mainstack.co

Speechius is a desktop teleprompter that scrolls when you speak. Speech recognition runs entirely on device and matches what you actually said against your script, so the text moves at your pace instead of a fixed speed. Pause and it waits. Go off-script and it catches up on its own. It is not a...

  • All-in-One Platform

  • Easy Storefront & Digital Product Sales
    Users can quickly set up digital storefronts to sell products, services, courses, and digital downloads without needing technical expertise or a separate e-commerce platform.
  • Built-in Payment Processing
    Mainstack offers integrated payment solutions that support multiple currencies and payment methods, making it easy for creators and businesses to receive payments globally.

    The platform is tailored for creators, freelancers, and small businesses, offering tools like customizable link-in-bio pages, portfolio showcases, and booking features that cater specifically to their needs.
  • No-Code Setup
    Mainstack requires no coding knowledge to get started. Users can build professional-looking pages, storefronts, and booking systems using intuitive drag-and-drop or form-based interfaces.

Possible disadvantages

  • Limited Brand Recognition
    Compared to established competitors like Gumroad, Shopify, or Linktree, Mainstack is less well-known, which may cause potential users to hesitate due to concerns about reliability and longevity.
  • Feature Depth May Be Limited
    While Mainstack offers many tools in one place, each individual feature may lack the depth and advanced functionality found in dedicated single-purpose platforms like Calendly for bookings or Shopify for e-commerce.
  • Limited Third-Party Integrations
    Mainstack may not offer as many integrations with popular third-party tools (e.g., email marketing platforms, CRMs, analytics tools) compared to more established competitors.
  • Smaller Community & Support Resources
    As a relatively newer platform, Mainstack has a smaller user community, which means fewer tutorials, forums, and peer-generated resources available for troubleshooting and learning.
  • Scalability Concerns
    While suitable for individual creators and small businesses, Mainstack may not offer the robust infrastructure and advanced features needed by larger businesses or those experiencing rapid growth.

Overall verdict

  • Mainstack is a solid all-in-one platform for creators, freelancers, and digital entrepreneurs in Africa (and beyond) who want to sell digital products, accept payments, and manage their online presence without needing separate tools for each function.

Why this product is good

  • Combines multiple tools (storefront, invoicing, payment links, link-in-bio) into a single dashboard, reducing the need for multiple subscriptions
  • Built with African creators and businesses in mind, supporting local payment methods and currencies which many global platforms lack
  • Simple, user-friendly interface that doesn't require technical or design skills to set up a professional-looking store or page
  • Supports selling digital products, services, and even physical goods with integrated payment collection
  • Offers analytics and customer management features to help creators track sales and grow their audience
  • Relatively low fees compared to piecing together multiple Western-centric SaaS tools that may not support local payments well

Recommended for

  • African creators, coaches, and freelancers looking to monetize digital products or services
  • Solopreneurs who want an easy way to accept payments locally and internationally without complex setup
  • Content creators needing a simple link-in-bio and storefront solution combined
  • Small business owners who want to send invoices and collect payments in one place
  • Individuals just starting out online who don't want to invest in multiple separate platforms (e.g., Shopify + Stripe + Linktree)

Questions & Answers

As answered by people managing Speechius and Mainstack.co.

What makes your product unique?

Speechius's answer

It recognises the words you actually say and finds them in your script, rather than scrolling on a timer or reacting to how loudly and quickly you speak. That means it still follows you when you rephrase a sentence, skip a line or jump back.

Recognition runs entirely on your own device, and the window can be excluded from screen sharing and screen recording.

Why should a person choose your product over its competitors?

Speechius's answer

Several teleprompters advertise voice-controlled scrolling, but most of them track your speaking pace and volume: they speed up when you speak faster and stop when you go quiet. They do not know which words you said, so going off-script or jumping back confuses them.

Speechius matches the recognised words against your script, which is the part that keeps working when you stop reading and start talking. It is also a one-time purchase rather than a subscription, and nothing is sent to a server.

How would you describe the primary audience of your product?

Speechius's answer

People who speak to a camera or an audience while their script has to stay out of sight:

  • Creators recording screencasts and tutorials
  • Trainers and teachers running online classes and webinars
  • Speakers rehearsing conference talks

Typically solo, on their own machine, without a studio setup.

What's the story behind your product?

Speechius's answer

I record programming tutorials for my own YouTube channel, and neither option worked for me: reading from a script sounds read, and improvising means losing the thread until a ten-minute recording takes forty. Existing teleprompters scroll at a fixed pace, so I ended up chasing the text instead of explaining.

I built the thing I wanted, and it turned into my first own product, released in July 2026.

Which are the primary technologies used for building your product?

Speechius's answer

  • Flutter for the user interface on macOS and Windows
  • Apple Speech for on-device recognition and window exclusion on macOS
  • Vosk, bundled as a local model, for recognition on Windows
  • Ed25519 signatures for licence keys, sold through Paddle
  • Sparkle for updates on macOS, Sentry for crash reporting
