If you have ever pasted text into an AI tool like ChatGPT, DeepSeek, or Gemini and paused for a moment, wondering if it is okay to include that name, brand, legal term, or private phrase, you are not alone. Most people move quickly, but if you work with sensitive content like client details, legal notes, or even fictional character names, it is a valid concern.
This is where Replaceo helps.
Replaceo offers a free browser tool that lets you find and replace multiple words in one step. You enter what you want to replace, like a person’s name or phone number, and what to swap it with, like a placeholder or pseudonym. It handles the replacement instantly. When you get your response or output back, Replaceo also helps you restore the original words quickly.
Your text never leaves your device. It all happens in your browser. It is a fast, private way to clean your text before using AI or sharing it with others.
AI tools are useful & powerful for writing, generating ideas, and editing. But they all share one important issue. As soon as you paste your content into the AI box, you give up control of it.
Even if the tool says your data is safe, you cannot be sure what happens. This matters more if your text includes legal content, internal notes, client references, or anything not public.
Replaceo offers a safer way. Before using any AI, you can mask private terms using placeholders. Then once you are done, you paste your AI response back into Replaceo and restore the original terms in seconds.
No setup is needed. Just open the tool, enter your swaps, and get started.
Replaceo is simple to use, even for non-technical users. Here is how it works:
Paste your own text into the Input Text Box
List the terms you want to replace in the Find Text column
Enter your replacement terms in the Replace With column
Click Replace to get the cleaned version
Once your AI task is done, paste the output back and click Revert to restore your original words
Original sentence
Sarah from Replaceo was unaware about the data masking.
Your replacements
Find Text: Sarah → Replace With: User
Find Text: Replaceo → Replace With: Company
Result
User from Company was unaware about the data masking.
You can now safely use that version anywhere. When you are done, bring the modified version and paste it in the Input Text Box, then click Revert to get back the original words.
