AI Writing Tool for ESL Business Professionals
Diglot is built for ESL professionals writing business English daily — product managers, consultants, sales engineers, marketers, customer success leads. L1-aware grammar checking, three-tier translation, register-calibrated paraphrasing, and persistent translation memory live in one editor. Stop juggling DeepL + Grammarly + ChatGPT; ship polished emails, proposals, and reports in a single workflow tuned for non-native speakers.
Business English has sharp register conventions native speakers absorb implicitly but ESL professionals have to learn deliberately: US emails default 50-150 words, Japanese keigo-influenced phrasing reads as servile in American business contexts, "kindly" carries Indian-English connotations US readers misread, "as per" reads as legalese. Diglot encodes these conventions and adapts feedback per L1 — so your emails sound senior, not translated.
- Format-specific templates — status emails, sales proposals, status reports, executive decks
- Register guidance — US vs UK conventions, formality calibration, common L1-influenced phrasings to avoid
- Translation memory — brand names, product terms, contract language stay consistent across every document
Why ESL professionals need a writing tool calibrated for register
Business English has sharp register conventions native speakers absorb implicitly but ESL professionals have to learn deliberately: US emails default 50-150 words, Japanese keigo-influenced phrasing reads as servile in American business contexts, "kindly" carries Indian-English connotations US readers misread, "as per" reads as legalese. Diglot encodes these conventions and adapts feedback per L1 — so your emails sound senior, not translated.
US business email defaults differ sharply from academic English: short paragraphs, action-oriented subject lines, explicit CTAs, no "kindly" or "as per". Diglot encodes these conventions so ESL professionals avoid the over-formal openings that signal "translated" to native readers.
Brand names, product terms, contract language, and team-specific jargon stay consistent across every email, proposal, or report you write. Team accounts share TM across collaborators, so onboarding new hires keeps voice consistent without re-explaining conventions every week.
Cold outreach, executive escalations, customer escalations, board updates — Diglot reduces the 30-90 minutes ESL professionals typically spend re-reading and re-editing high-stakes English to 5-10 minutes per document, with confidence the register is right.

Frequently asked questions
Everything you need to know before getting started.
Can Diglot help with business writing?
Yes — business writing is the strongest use case for ESL professionals. Diglot covers transactional emails (status, follow-up, cold outreach), sales proposals, customer-success communications, status reports, performance reviews, executive presentations, vendor scoping, and internal documentation. Each format has register guidance calibrated for US vs UK conventions and L1-specific pitfalls.
Is it only for native speakers?
No — Diglot is specifically built for ESL professionals. Generic business writing tools (Grammarly Business, Wordtune Business) assume native-English baselines. Diglot calibrates for the predictable L1-transfer patterns: Japanese over-formalization, Korean honorific-derived politeness, Spanish false cognates, Chinese aspect-marker flattening, Russian long subordinate chains, Arabic definite-article overuse. Each is recognized and explained, not just flagged.
Can I use Diglot for multilingual client communication?
Yes — multilingual client comms is a core use case. Translate inbound client emails from their L1 into English, draft responses in your L1, translate to English with three-tier output (literal/idiomatic/formal), polish with the L1-aware grammar checker. Translation memory keeps client-specific terminology consistent across every touchpoint. Especially valuable for sales engineers, customer success leads, and account managers handling cross-border accounts.
Does Diglot help with tone and wording?
Yes — tone and register are first-class concerns. The AI writing assistant adapts output to target register (executive, peer, vendor, customer). The paraphraser offers tone modes (formal, conversational, direct). The grammar checker flags register mismatches — over-formal openings, under-formal CTAs, locale-confused phrasings ("kindly" in US business, "revert" for "reply" outside Indian English). Result: your emails sound like a confident senior, not a translated junior.
Is Diglot useful for remote teams that work in English?
Yes — distributed teams with ESL members benefit most. Team accounts share translation memory and approved phrasings, so onboarding new hires keeps voice consistent without re-explaining conventions. Async-friendly tools (paraphrasers, templates, register-aware suggestions) reduce the synchronous review burden senior native-English colleagues otherwise carry. Multilingual standup notes, sprint reports, and decision docs all stay polished.
How does Diglot reduce time spent on business writing?
Three ways: (1) Templates pre-encode format and register, eliminating 15-30 minutes of structure-figuring per document. (2) L1-aware corrections explain patterns in your native language, so you internalize the pattern and produce cleaner first drafts over time. (3) The unified editor (grammar + paraphrase + translation + originality) eliminates the 4-tab juggle that doubles editing time. Senior ESL professionals report 30-60 minute savings per week on email alone.

ESL business professionals — product managers at multinational companies, consultants serving cross-border clients, sales engineers running deals in English, customer success leads handling escalations, marketers producing English content — face a specific challenge that generic business writing tools were never designed for: they need polished, register-appropriate business English at the pace of daily work, not the pace of careful editing. Native business English carries conventions native speakers absorb implicitly but ESL professionals must learn deliberately: US business email defaults 50-150 words (compared to 300+ in Japanese keigo-influenced English); subject lines should signal action ("Decision needed: Q3 budget") rather than just topic ("Q3 budget"); "kindly" reads as servile in American English even though it sounds polite to Indian or South Asian writers; "as per" reads as legalese to most US readers but is standard in Indian and British business English; "revert" means "reply" in Indian English but means "return to a prior state" to US readers. These register conventions multiply across L1s — Japanese keigo doesn't map cleanly to US neutral; Korean honorific levels produce English that reads as servile; Spanish formality (tú/usted) doesn't carry to English; Chinese politeness markers are less morphologically explicit and can read as cold; Russian directness reads as curt in American business contexts. Diglot encodes all of these conventions plus L1-specific calibration. The grammar checker recognizes L1-transfer patterns and explains corrections with the native-language reason. The paraphraser offers tone modes calibrated for target audience (executive, peer, vendor, customer). The translation memory keeps brand names, product terms, and contract language consistent across every email, proposal, and report. Format-specific templates (cold outreach, status email, executive presentation, performance review) encode US business norms by default with optional UK or APAC variants. All four tools share document context inside one editor — so the workflow stops requiring DeepL + Grammarly Business + QuillBot + ChatGPT in four browser tabs.
