AI Paraphrasing Tool for ESL & Non-Native Writers
Diglot paraphrases L1-flavored English into natural prose without losing your meaning. Tuned for Korean topic-comment structures, Spanish false cognates, Chinese aspect markers, and Russian long subordinate chains — patterns QuillBot and Wordtune treat as generic English. Works inside the same editor as grammar checking and translation, no copy-pasting between tabs.
QuillBot rewrites sentences as if everyone writes from the same baseline English. ESL writers do not — Korean writers chain -고/-며 connectors into comma splices, Spanish writers paste false cognates like "actually" for "actualmente", Chinese writers flatten tense. Diglot recognizes these L1 patterns and rewrites them into native English while preserving your meaning, citations, and technical vocabulary.
- L1-aware rewrites — Korean topic-comment, Spanish false cognates, Chinese aspect markers all handled
- Multiple alternatives per sentence — formal, idiomatic, simplified — pick what fits your reader
- Technical-term lock keeps domain vocabulary (medical, legal, CS) intact during rewrites
Why ESL writers need more than a generic synonym swap
QuillBot rewrites sentences as if everyone writes from the same baseline English. ESL writers do not — Korean writers chain -고/-며 connectors into comma splices, Spanish writers paste false cognates like "actually" for "actualmente", Chinese writers flatten tense. Diglot recognizes these L1 patterns and rewrites them into native English while preserving your meaning, citations, and technical vocabulary.
QuillBot rewrites everyone the same way. Diglot offers two paths for L1-flavored sentences: one preserves natural information order for readers familiar with the source culture; the other fully Anglicizes structure for native-English readers. You choose.
Strips the generic patterns ChatGPT produces — "It is important to note", mechanical "Moreover" chains, parallel structures every paragraph. Keeps your authentic voice intact, including the natural L1-flavored rhythm where appropriate.
Paraphrase, then immediately grammar-check, translate a reference passage, or verify originality — all in the same editor. QuillBot, Wordtune, and Grammarly force four tabs and four copy-pastes; Diglot keeps your bilingual document anchored in view.

Frequently asked questions
Everything you need to know before getting started.
Diglot rewrites sentences and paragraphs to improve clarity, fluency, and originality while preserving your meaning, citations, and technical terminology. For ESL writers it specifically targets L1-transfer patterns — Korean topic-comment word order, Spanish false cognates, Chinese aspect-marker drops, Russian long subordinate chains — that generic paraphrasers treat as random awkwardness rather than predictable patterns.
QuillBot and Wordtune rewrite everyone the same way regardless of native language. Diglot is L1-aware — Korean writers get topic-comment alternatives; Spanish writers get false-cognate scrubbing; Chinese writers get aspect-marker mapping. Each rewrite is grounded in contrastive linguistics, not generic synonym substitution. Plus paraphrase, grammar, and translation share one editor instead of three.
Yes — academic paraphrasing is a primary use case. Diglot preserves citation eligibility (paraphrase + citation hint mode prompts you to add inline citations), keeps technical vocabulary locked, and offers register modes (formal, academic, conversational). Especially useful for thesis chapters and grant abstracts where reviewer-acceptable phrasing matters as much as semantic accuracy.
Yes — that is the core promise. ESL writers often produce "translated English" that is grammatically correct but feels slightly off to native readers. Diglot identifies the L1-transfer patterns producing that off-ness (preposition errors from German, subjunctive overuse from Spanish, copula drops from Russian, modifier-noun chains from Japanese) and rewrites them into natural English without flattening your authorial voice.
Yes — paraphrasing, grammar checking, translation, and originality verification all share the same document context inside Diglot. Translate a paragraph from your L1, run a grammar pass, paraphrase awkward sentences, and verify originality before publishing — without copy-pasting between four browser tabs. Per-writer translation memory keeps technical terms consistent across the whole workflow.
Yes — the free plan includes core L1-aware paraphrasing for the top six L1s (Korean, Chinese, Japanese, Arabic, Spanish, Russian). Spark ($19/month) and Pro ($29/month) unlock higher monthly word quotas, larger document sizes, premium model tiers for more nuanced rewrites, and access to the AI-text humanization mode for cleaning ChatGPT-generated drafts.

AI paraphrasing for ESL writers is fundamentally different from generic English-to-English rewriting. The hard cases are not random awkward sentences — they are predictable L1-transfer patterns. A Korean writer chains -고/-며 connectors into English comma splices because Korean conjunctive endings have no direct equivalent. A Spanish writer pastes "actually" for "actualmente" without realizing the false cognate flips the meaning from "currently" to "in fact". A Chinese writer flattens English tense because Mandarin does not inflect verbs. A Japanese writer over-formalizes business English because keigo register cues do not map cleanly to US business neutral. Generic paraphrasers — QuillBot, Wordtune, Grammarly's paraphrase mode — treat each of these as random awkwardness and rewrite them with one-size-fits-all synonym substitution, often making the result less natural rather than more. Diglot is the only paraphrasing tool built around L1-transfer pattern recognition. Each rewrite is grounded in contrastive linguistics drawn from published ESL research and live error corpora. Korean writers see two rewrite paths — one that preserves natural Korean information order for readers familiar with Asian academic style, one that fully Anglicizes structure for Western reviewers. Spanish writers get explicit false-cognate scrubbing. Chinese writers get aspect-marker mapping (le/guo/zhe routed to past/perfect/progressive). All inside the same editor as the grammar checker, translator, and originality verifier — so the bilingual workflow stops requiring four browser tabs and four copy-pastes. Free for the top six L1s, with higher quotas on Spark and Pro plans.
