About useEffect.dev and Not A Translator

In their own words, as submitted to SaaSHub.

useEffect.dev
Not A Translator

No description of useEffect.dev yet.

Most translator extensions swap a word for its equivalent in your language — and you learn nothing. Not a Translator flips that: select a word, right-click "Get the meaning for it," and see its definition in the language you're reading, inline. That's how vocabulary actually sticks. One click...

Features and specs

What each product offers, as listed by its team.

useEffect.dev 5 features
Not A Translator 10 features
  • 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  • Potential for outdated content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(e.g., the shift toward React Server Components and away from useEffect in some patterns), the content may become outdated if not regularly maintained and updated.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.
  • dictionary lookup
    see a word's definition in the language you're reading it in, via right-click — no translation needed
  • console mode
    fallback search when tooltip injection is blocked by heavy JS/iframes on some pages
  • Timezone handling
    convert a time in the local timezone
  • Conversion Capabilities
    convert temperature length and other measurement units
  • Translations
    several language supported, various sources for each (EN, ES, FR, DE, FI, Latin+Greek)
  • SenseMap
    a graph of synonyms, antonyms, and more... (optional feat.)
  • RootMap
    a graph of etymons, meronyms, hyperonyms and more... (optional feat.)
  • pdf reader
    integrated pdf reader to anotate and translate inside pdfs. (optional feat.)
  • reader mode
    distraction-free reading view, auto-suggested after a couple of lookups so to get not a translator available while reading in dark mode (optional feat.)
  • collapsible highlights
    drag-and-drop highlights that reopen the tooltip on click. move it around your selection for visibility/readability.

Analysis

An editorial look at what each product does well and who it suits.

useEffect.dev
Not A Translator

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 useEffect.dev and Not A Translator.

What's the story behind your product?

Not A Translator's answer:

It started from a simple frustration: translating a word to my native language never actually taught me anything — I'd forget it five minutes later, and I didn't want to lose my reading flow every time a word escaped my understanding. So I built a tooltip app that shows the definition in the language I'm reading instead, which forces just enough extra effort to make the word stick. this started in 2020-21. It's grown since then into a small ecosystem — unit/time conversion, an optional PDF reader, and deeper lookup tools for supporters. All with ferature requests from family and friends who use it.

What makes your product unique?

Not A Translator's answer:

Instead of swapping a selected word for its translation, Not A Translator shows the word's definition in the language you're already reading — via an inline tooltip triggered from the right-click menu. That's the difference between translating and actually learning. It also converts units and times inline, and supporters can unlock deeper features like a contextual synonym/etymology map (SenseMap & RootMap), an integrated PDF reader, and dark mode support.

Why should a person choose your product over its competitors?

Not A Translator's answer:

Most translator extensions just swap a word for its equivalent in your language — convenient, but you forget it five minutes later. Passive tools replace random words for you, so you don't control what you learn. Not A Translator stays out of your way until you actually need it: select the word you don't know, right-click, and get its definition in its own language, right where you're reading. A one-click translation is still there for when you just want the quick answer. intuitive, cosy...

How would you describe the primary audience of your product?

Not A Translator's answer:

People learning a language, expats reading news or documents in a language they're still working on, students, and anyone who doesn't want to leave the page every time they hit a word they don't fully understand.

Which are the primary technologies used for building your product?

Not A Translator's answer:

A Chrome/Firefox browser extension built in JavaScript. It uses Readability.js for clean text extraction and PDF.js for the integrated PDF reader, with graph rendering for the SenseMap/RootMap features handled via TouchGraph. Development was old school coding thrn it has been AI-assisted since version 4.0-5.0. Supporter features are gated through a lightweight token system, verified via a Cloudflare Worker and a small backend.
