About Speechius and useEffect.dev

In their own words, as submitted to SaaSHub.

Speechius
useEffect.dev

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...

Features and specs

What each product offers, as listed by its team.

Speechius 10 features
useEffect.dev 5 features
  • Voice-following scroll
    The script moves only when you actually say the next words. Pause and it waits.
  • On-device speech recognition
    Apple Speech on macOS, a bundled Vosk model on Windows. Nothing leaves your machine.
  • Recognition languages
    English and German
  • Hidden on screen share
    The window can be excluded from screen sharing and screen recording.
  • Anchor line
    Drag the focus line to where you read; the text balances around it.
  • Window transparency
    Adjustable, so you keep an eye on what is behind the script.
  • Always on top
    Pin the window above any application, including Zoom, Meet, Teams and OBS.
  • Skip words
    Mark names the recognizer never gets right so they are ignored.
  • Slide triggers
    Mark words in your script that advance your slides automatically.
  • Licence
    One-time purchase, no subscription, 14-day trial.
  • React-focused learning resource
    useEffect.dev is a specialized resource dedicated to helping developers understand and master React's useEffect hook, one of the most commonly used but often misunderstood hooks in the React ecosystem.
  • Practical examples
    The site provides practical, real-world examples of useEffect usage patterns, making it easier for developers to learn how to properly implement side effects in their React components.
  • Niche expertise
    By focusing specifically on useEffect, the resource can go deep into edge cases, best practices, and common pitfalls that more general React tutorials might gloss over.
  • Accessible for beginners
    The site is designed to be approachable for developers who are new to React hooks, providing clear explanations that help bridge the gap between class component lifecycle methods and the hooks paradigm.
  • Free online resource
    As a web-based resource, it is freely accessible to anyone with an internet connection, lowering the barrier to learning about React's useEffect hook.

Possible disadvantages

  • Narrow scope
    The site is extremely focused on a single React hook, which limits its usefulness as a comprehensive learning resource for React development as a whole.
  • Limited community and recognition
    useEffect.dev is not a widely known or heavily trafficked resource compared to the official React documentation or popular platforms like freeCodeCamp or Egghead, which may mean less community support and fewer peer-reviewed contributions.
  • Potential for outdated content
    As React evolves rapidly (e.g., the shift toward React Server Components and away from useEffect in some patterns), the content may become outdated if not regularly maintained and updated.
  • May not cover advanced patterns sufficiently
    While useful for understanding useEffect basics, the resource may not fully cover more advanced state management patterns or alternatives like useQuery, useSWR, or other libraries that abstract away direct useEffect usage.
  • Lack of interactive features
    Compared to platforms with interactive coding environments, sandboxes, or exercises, the site may offer a more passive learning experience that doesn't fully engage developers in hands-on practice.

No analysis of Speechius yet.

Overall verdict

  • useEffect.dev appears to be a niche educational resource focused on React's useEffect hook and related hooks concepts, useful for developers who want targeted explanations and examples rather than a full-scale course platform.

Why this product is good

  • Focuses specifically on a commonly confusing React concept, which can save time compared to searching broader documentation
  • Likely provides practical code examples that clarify real-world usage patterns
  • Can serve as a quick reference for debugging common useEffect pitfalls like dependency arrays and cleanup functions
  • Being narrowly scoped, it may be easier to digest than lengthy general React courses

Recommended for

  • Junior to mid-level React developers seeking clarity on useEffect specifically
  • Developers debugging issues related to effect dependencies or infinite render loops
  • Self-taught programmers who prefer concise, topic-specific resources over full courses
  • Teams looking for a quick reference link to share with newer developers on the team

Questions & Answers

As answered by people managing Speechius and useEffect.dev.

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
