How to bulk-replace text on any website without coding

If you've ever found yourself mentally substituting words while reading a webpage — replacing a company name, correcting a repeated typo, or swapping one term for a preferred alternative — you already know why bulk text replacement in the browser is useful.

Rewritr lets you do exactly this: set up rules once, and apply them to any page in one click. No code. No configuration files. No developer tools. Here's how.

Step 1: Install Rewritr

Go to the Rewritr homepage and click Add to Chrome — Free. The extension installs in seconds and adds an A→B icon to your toolbar. Pin it for easy access.

Step 2: Open the popup and add your first rule

Click the Rewritr icon on any webpage. You'll see one empty rule row waiting for input.

1. Click the Phrase / Pattern field (left column) and type the text you want to find.
2. Click the Rewrite to field (right column) and type the replacement text.
3. Click ▶ Apply.

That's it. The page updates instantly with every occurrence replaced.

Step 3: Add multiple rules at once

The real power of Rewritr is running many replacements in a single Apply. Click ＋ in the header to add more rows. Each rule runs independently, top to bottom.

A practical example: you're reading a competitor's product documentation and want to mentally map their terminology to your own company's:

Phrase         → Rewrite to
─────────────────────────────
WorkspaceX     → My Company
Channels       → Spaces
Bots           → Automations
Reactions      → Emoji responses

Click Apply once and the entire page reflects your vocabulary.

Step 4: Use flags for precision

Each rule has four optional flags to control how matching works:

• Cs (Case Sensitive) — match only the exact case. Useful when you want to replace "API" but not "api".
• Ww (Whole Word) — only replace when the phrase is a complete word. This prevents replacing "Java" inside "JavaScript" — probably the most commonly needed flag.
• Sc (Smart Case) — preserve the capitalisation pattern of the original. Replace "Cloud" → "Sky" and "CLOUD" → "SKY" automatically.

Step 5: Save your rules as a bookmark

Once you've built a useful set of rules, you can save it as a named bookmark so you don't have to re-enter it next time.

1. Click the 🔖 icon in the popup header.
2. Click ＋ Save Current.
3. Give the set a name (e.g. "Competitor docs", "Work jargon", "Proofreading").

To reload a saved set later, open the bookmarks panel and click ⬇ Load.

Step 6: Enable Dynamic mode for live pages

Some pages load content dynamically — news feeds, social media timelines, infinite scroll lists, and single-page apps. After you click Apply, new content that loads won't be automatically replaced.

Enable the Replace on page changes (dynamic) toggle at the top of the popup, then Apply. Rewritr will keep watching the page and apply your rules to any new content as it appears.

Practical use cases

• Reading privacy: Replace real names with pseudonyms on public sites you screenshot and share.
• Vocabulary mapping: Translate competitor jargon into your own company's terminology while reading docs.
• Editing while reading: Catch and fix your own repeated typos on drafts open in a CMS or Google Docs.
• Personalisation: Replace generic placeholder names in tutorials ("Lorem Ipsum Corp") with something more meaningful.
• Accessibility: Replace uncommon abbreviations with expanded forms on sites that don't annotate them.

Exporting and sharing rules

To back up your rules or share them with a colleague, click ⬇ Export at the bottom of the popup. This downloads a .json file that can be imported on any Chrome installation with Rewritr.

Summary

Rewritr's core workflow is three steps: add rules, click Apply, done. The flags give you precision without complexity, bookmarks give you persistence, and Dynamic mode handles pages that keep loading. No programming required — just type, click, and the page rewrites itself.
