Catch Mistakes Before You Send

Typos happen. Grammar mistakes slip through. Usually you only notice after you've hit send.

Spell check switches on the spell checker already built into your browser, for the whole page. Misspelt words get the red wavy underline as you type. Grammar is a separate feature that checks a passage when you press Check.

Learn how to use the Spell Checker

  • Word Prediction - Get typing suggestions that help prevent misspellings before they happen.
  • Voice Typing - Reduce typos entirely by speaking your message instead of typing.
  • Dictionary - Look up definitions to use the right word with confidence.

Where It Works

Gmail: Check your emails before sending.

Web forms: Anywhere you type online.

Most text fields: If you can type there, the spell checker can help.

Not Google Docs: Google Docs draws its own text instead of using a normal text box, so no browser spell checker reaches it.


What Gets Checked

Spelling: Misspelt words get the familiar red wavy underline as you type. Right-click one and your browser offers corrections.

Boxes that leave the setting alone: Spell check sets the attribute on the page body, so text boxes that do not set their own value pick it up. A box where the site explicitly switched spell checking off keeps its own setting and stays off.

Your browser's own checker: Helperbird switches on the spell checker already built into Chrome, Edge, Firefox or Safari. Nothing you type is sent anywhere.

Grammar is a separate Helperbird feature. You paste or select a passage, press Check, and it comes back with the grammar, spelling and punctuation corrected. It does not change your meaning or tone, it does not run as you type, and the passage goes to OpenAI for the check. See how to check grammar and spelling.

This extension has been an absolute lifesaver. I have that fantastic combo of ADHD and Dyslexia while trying to go through college. I have difficulty keeping letters in order, seeing the gaps between words, and with ADHD on top, I lose focus A LOT. The immersive reader has been my new best friend. It drowns out the rest of the content on the page, changes the font to something I can read, and highlights the word as it reads to me. My eyes are forced to keep going in the right direction. I can slow down and pay attention to what I'm reading. I don't even have to go back and read the same paragraph 5 times to understand it! The screen overlay has been outstanding for eye strain and being able to distinguish between words and spaces. The custom font and spacing for research articles have been an enormous advantage! I can actually read the research papers now and not have this daunting 2 column fine print page to squint over.All around, this has been the best purchase I've ever had. I use this every day, with every assignment. I don't even struggle with story-based questions anymore. The immersive reader helps me read, listen, and understand the question all at once. I am still exploring what I can use this with and how it can make my academic career, and I keep getting impressed with every new way I find to use it. Seriously, try it out. You won't regret it at all. Even if you don't have dyslexia or ADHD, just try it out. You might find that it helps you understand the content you're trying to learn even better!
