Paraphrasing Tool for ESL Students
Diglot’s paraphrasing tool is built for ESL writers, not native ones. It rewrites the translated-sounding, L1-flavored sentences that generic tools turn to mush — holding onto your meaning, guarding names and numbers, and steering clear of the mangled phrasing that trips detectors. And you rewrite in the same editor where you draft and translate.

Why ESL writers need a paraphraser built for them
Feed a QuillBot-style paraphraser a second-language sentence and it swaps a few synonyms, leaving phrasing that reads worse than what you wrote and sets off detectors. A Korean writer’s chain of -고/-며 connectors becomes a 40-word English run-on; the synonym pass just renames the words inside it. ESL sentences need a rewrite that fixes the L1 structure, not thesaurus noise — and a check that the meaning survived. That’s what Diglot’s paraphraser is tuned for, with a semantic guard watching that the new version still says what you meant.
Apologetic fluff & boilerplate
Defaults to verbose, deferential openings ("I hope this email finds you well", "I am writing to kindly inquire"). Reads as subordinate and wastes senior stakeholders' time.
Native-speaker syntax bias
Catches basic comma splices and spelling typos, but completely misses L1 cultural transfers, Japanese Keigo servility, Spanish false cognates, or tone mismatch.
Isolated sentence translation
Translates sentences accurately in isolation, but lacks document-level tone calibration, context memory, and consistent business terminology across releases.
Calibrated executive workspace
In-place three-tier translation, register calibration, L1-transfer neutralization, and persistent translation memory inside a single focused editor.
Built around real bilingual business workflows
Everything non-native professionals need to write, translate, and verify high-stakes English in one place.

Confirm the meaning held

Frequently asked questions
Everything you need to know before getting started.
Is this paraphrasing tool good for ESL students?
Yes — it’s built specifically for non-native writers. Where a generic tool swaps synonyms, Diglot rebuilds the L1-flavored structure that makes a sentence sound translated, and keeps your meaning while it does. It also avoids the tortured phrasing generic paraphrasers leave behind, the kind that reads worse and gets flagged by detectors.
Will it change my meaning?
It’s designed not to. A semantic-similarity guard checks the rewrite still means what you wrote, and entity preservation keeps names, numbers, and facts fixed. You can line up the original and the rewrite before accepting, so the claim stays yours.
How is this different from QuillBot?
QuillBot is a general paraphraser built on synonym swapping for native English users. Diglot’s targets ESL sentences — it fixes the translated structure and L1-transfer patterns, not only the vocabulary, and it lives in the same editor where you draft and translate. For non-native writers that means more natural output and one less tab to babysit.
Can it help me paraphrase without plagiarizing?
Yes. Meaning-preserving rewrites let you rework a source-derived passage into your own words while the citation stays, and you still cite the source. That’s safer than synonym-swap paraphrasing, which tends to leave near-duplicate text that still overlaps the source.
Is it free?
Yes — the free plan includes core paraphrasing alongside grammar and translation. Paid plans raise the quotas, add premium models, and unlock the additional rewrite modes for heavier work.

Swapping a few synonyms while keeping the source's sentence structure is "patchwriting" — and it counts as plagiarism even when you cite it. Here is the method that actually works, with before-and-after examples and the rule non-native writers most often miss.
Tortured phrases are the absurd word swaps that synonym-spinning paraphrasers leave behind: "counterfeit consciousness" for "artificial intelligence", "bosom peril" for "breast cancer". Where the term comes from, the most famous examples, why ESL writers are most exposed, how detection works, and what honest paraphrasing looks like instead.
Generic paraphrasers swap synonyms in English-only; Spanish speakers often need false-cognate detection, se-passive restructuring, and a side-by-side bilingual view. This guide shows exactly when each type of tool is the right choice — with a five-minute test you can run on any paraphraser.
Write in your language,
publish in English
Move from rough bilingual drafts to clearer English in one connected writing workflow.
Most paraphrasing tools were built for native English users who just want to reword themselves, so they run on synonym swapping — and when you hand them a second-language sentence, they produce tortured phrasing that reads worse than the original and sets off AI and plagiarism detectors. ESL writers need something else: a rewrite that fixes the translated structure, not the vocabulary. A Korean writer’s chain of -고/-며 connectors lands in English as one breathless run-on, and swapping the nouns inside it changes nothing.
Diglot’s paraphraser is built for exactly that. It targets the L1-transfer patterns that make a sentence read non-native — literal calques, awkward collocations, source-language word order and run-ons — and rewrites them into natural English while a semantic guard confirms the meaning held and entity preservation keeps your names, numbers, and facts steady. Because it lives in the same editor where you draft and translate, you rewrite a clumsy or flagged sentence in context instead of pasting it into a separate tool and losing the paragraph around it.
What comes back is English a native reader accepts — meaning intact, phrasing natural, and not a thesaurus pass wearing a disguise.
