Paraphrasing Tool by ContentBot.ai vs MaskMyPrompt

Paraphrasing Tool by ContentBot.ai rewrites up to 2,000 words at a time through a paragraph-by-paragraph workflow in your browser. Paste an article, let the rewriter process each section, and regenerate any paragraph that needs more distance from the source. A built-in variability score uses Levenshtein distance so you can see how far the new text sits from the original before publishing.

Standalone paraphrasers often spit out shallow synonym swaps, while ContentBot pairs long-form rewriting with a plagiarism checker and a short-form mode for single sentences in 110+ languages. Low-variability outputs do not consume credits, which matters when you are batching rewrites for SEO or client drafts. The trade-off is that full access lives inside the broader ContentBot subscription rather than a one-off paraphrase-only app.

Copywriters, bloggers, and SEO specialists use it to refresh existing posts, reduce duplication risk, and test tone shifts from professional to playful in the short-form rewriter. Premium workspace access starts at $29 per month on the main ContentBot site with 150,000 words, while prepaid plans charge $0.50 per 1,000 words with 10,000 free words on first purchase.

MaskMyPrompt lets you anonymize ChatGPT prompts by swapping real names for fake ones before you paste anything into the model. It works as a lightweight paraphraser focused on privacy: scan your text for people, organizations, and locations, then replace them with made-up stand-ins so confidential details never reach ChatGPT. Everything runs locally in your browser tab using Transformers.js, and the site states your prompt data is never saved or sent to any server.

Most privacy wrappers route text through a backend API, which means you still trust a third party with the raw input. MaskMyPrompt keeps the entire masking step on your device, which is a narrower but more private approach. The trade-off is a single-page utility with no team features, no pricing tiers, and no integrations beyond copy-paste into ChatGPT.

It fits developers, researchers, and anyone drafting ChatGPT prompts that mention real people or companies. Mike Ushakov built the tool, and you can reach him via email or Twitter for bug reports and feature requests.
