Features That Make Browser Writing Effortless
Write Better Assistant packs every action you need into one floating toolbar that appears right next to your selected text. Improve writing, translate, change case, copy and paste, and review history, all without a sidebar, tab switch, or copy-paste loop. Below is a full breakdown of every feature and how it fits into your day.
Improve: The Core AI Writing Action
One Button That Opens Seven Targeted Rewrite Options
Improve is the main AI button on the floating toolbar. Click it once and a dropdown opens with seven targeted rewrite actions. Each one is built for a specific writing job, so you do not get a one-size-fits-all rewrite that strips your voice.
Pick the action that fits the moment. Need a cold email warmer? Pick Make Friendly. Drafting a pitch deck note? Pick Make Professional. Writing to a senior stakeholder? Pick Write as Email. Each action runs in seconds and swaps the text in place.
The Improve menu also remembers your last action so a second click runs the same rewrite without re-opening the dropdown. That small detail saves seconds across the day when you are fixing many notes in a row.
Turn a rough idea into a clean, structured prompt for any AI chat tool. Add context, set the goal, and shape the ask in one click so the model gives you a sharper answer on the first try.
Shift tone toward formal for client work, sales notes, and stakeholder updates. Your meaning stays intact, but the phrasing reads as crisp and business-ready, perfect for cold outreach or executive emails.
Warm up cold or blunt replies for support tickets, team chats, and customer notes. The tone softens, the message lands better, and you stop sounding terse without losing the core point.
Catch typos, agreement slips, and small grammar errors in place. The fix is fast, native-sounding, and keeps your voice, ideal for non-native English speakers and anyone typing in a hurry.
Turn a few bullet notes or a quick thought into a full draft message with a greeting, body, and sign-off. Great for replying to long threads when you only know the gist of what you want to say.
Trim fluff, cut filler words, and get to the point fast. Useful for Slack notes, social posts, and any text where length is hurting clarity.
Add depth, context, and supporting detail when a draft feels too thin. Helpful when you have the right idea but need more substance for a doc, post, or pitch.
Translate: Move Text Across Key Languages Fast
Click Once, Pick a Language, See the Text Swapped
Translate sits on the toolbar as its own action. Click it and a list of supported languages opens. Pick the target language and the selected text is swapped in place with a clean, native-style translation that keeps the meaning intact.
You can set preferred languages in the extension options so the list shows the languages you use most at the top. That cuts the click count when you bounce between two or three working languages all day.
Translate is built for ESL writers, support teams that handle multilingual queues, and any team that spans borders. The output reads as native, not machine-translated, so you can send it without a second review pass.
If your target language is not in the preferred list, the full set is always one click away. We add more languages over time based on what users ask for.
Change Case: Eight Styles for Writing and Code
Built for Writers, Developers, and Anyone in Between
Change Case is a quiet workhorse on the toolbar. It does not use AI. It just converts your selected text into one of eight case styles in a single click. No copy to a separate tool, no online converter to find.
The eight styles cover both prose and code. Writers reach for Title Case and Sentence case. Developers reach for CONSTANT_CASE, param-case, and snake_case. Marketers reach for UPPERCASE on labels and headlines.
Pick any style and the swap is instant. There is no AI call, no waiting, no quota cost. Use it as often as you need throughout the day.
All letters in capital form. Best for emphasis, labels, and headings that need to stand out.
All letters in lower form. Useful for code variables, casual notes, and stripping out shouty caps.
Major words capitalized. The default style for headlines, section titles, and product names.
Only the first word capitalized. The right style for prose, body copy, and most everyday writing.
Upper letters joined by underscores. The convention for environment variables and named constants in code.
Lower letters joined by dashes. The standard for URL slugs, CSS class names, and CLI flags.
Lower letters joined by underscores. The convention for variable and function names in Python, Ruby, and many other languages.
Plain lower letters joined by spaces. A clean baseline you can convert into any other style.

Copy, Cut, and Paste: Right on the Toolbar
Classic Clipboard Actions Without the Right-Click Menu
Copy, Cut, and Paste live right on the floating toolbar. When you select text, these actions show up next to the AI buttons so you can grab or drop content without a right-click menu or a keyboard shortcut.
The big win is consistency. Some sites trap right-click menus, block copy events, or strip formatting on paste. The toolbar actions work the same way on every site so you never have to learn a new pattern per page.
What the Clipboard Actions Cover
- Copy lifts your selected text to the clipboard without leaving the page or opening a menu
- Cut removes the selected text and stores it on the clipboard in a single click
- Paste drops your clipboard content into the active field right where you need it
- Each action sits one click away on the floating toolbar, no right-click menu required
- Works the same on Gmail, Slack, Notion, X, and most browser text fields
History: Every Rewrite Saved on Your Device
Recover Past Edits With a Single Click, Anytime
Every time you run a rewrite, the original and the result are saved to your local history. If a fix went too far, you can pull up the old version, copy it back, and move on without losing what you wrote.
The history view in the extension popup lets you scroll past actions, filter by action type, and see which site the edit came from. That makes it easy to find the Slack reply you rewrote yesterday or the email draft you trimmed last week.
Privacy is the key part. History stays on your device. We do not store the text you fix on our servers, and we do not train on your edits. You can clear the log any time from the popup if you want a clean slate.
What History Tracks for You
- Every rewrite is saved locally so you can recover an earlier version if a fix went too far
- Browse past actions by date, action type, or source site to find what you wrote last week
- One-click restore copies an old result back to your clipboard for instant reuse
- History stays on your device. We do not store your edits on our servers
- Clear the log any time from the extension popup if you want a clean slate
