Your draft
Many researches shows that students which use social media more than three hours per day have lower grades. In our opinion this is because the constant notifications make difficult to concentrate, so the information is not stay in the memory.
We propose to migrate our reporting to the new platform in Q1. This will reduce costs a lot and the team will be more productive, because the old system is very slow and nobody likes it.
We are very sorry for the delay, it was not our fault but the supplier one. We will try to send you the goods until Friday, please be patient with us and don’t cancel the order.

The Transformer replaced recurrence with attention alone , and pre-trained encoders such as BERT carried the idea to language understanding . Attention mechanisms first improved neural machine translation .

FAQ
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.
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.
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.
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.
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, 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.
Two ways: (1) L1-aware corrections explain patterns in your native language, so you internalize the pattern and produce cleaner first drafts over time. (2) The unified editor (grammar + paraphrase + translation) eliminates the 3-tab juggle that doubles editing time. Senior ESL professionals report 30-60 minute savings per week on email alone.
