AI Writing Assistant for International Students
Diglot is built for international students writing admissions essays, coursework, and applications in English as a second language. Draft in your first language, get grammar feedback that explains itself in terms you recognize, and finish with proof you wrote it — so one false AI flag can’t put your grade, or your visa, on the line.

Access to urban green space is increasingly treated as a public-health variable rather than an amenity. Across the twelve municipalities surveyed here, residents living within 300 m of a maintained park reported measurably lower psychological distress, and the effect persisted after adjustment for income and housing tenure (Ferreira et al., 2026).
This review synthesises fourteen longitudinal studies published between 2014 and 2025. Two methodologycal limitations recur across them: self-selection into greener neighbourhoods, and exposure measured by proximity rather than by actual use (Tisdell & Bandara, 2004).

Why generic AI tools fail international ESL students
Generic checkers flag false positives on ESL academic phrasing or inject conversational hedging that undermines academic rigor and integrity.
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.
Register & Formality Calibrator
Calibrate writing to target US vs UK executive norms. Neutralize Keigo-style subservience, legalese filler, and culturally awkward greetings before sending to leadership.
- Senior Executive vs Peer tone tuning
- Eliminates "kindly", "as per", and "revert"
- Action-oriented CTA phrasing
Three-Tier Inline Translation
Translate difficult words or full sentences inline without leaving the editor. View Literal, Idiomatic, and Executive Business translations side-by-side.

One connected workflow from raw draft to final deliverable
Move from bilingual rough ideas to polished English in one calm flow instead of stitching together separate tools.
Draft in your first language
Capture the idea without forcing perfect English, keeping your native-language source in the same editor as the English you are building.
Translate and refine into English
Translate passages inline and polish the English side by side, so your essay or application reads naturally instead of translated.
Structure the high-stakes documents
Use register and structure guidance for personal statements, statements of purpose, and scholarship essays calibrated for non-native writers.
Finish with proof you wrote it
Your writing process is recorded into an Authorship Certificate, so a false AI flag never puts your grade or application at risk.
Built for high-stakes business communicators
Diglot works best when English is your delivery language, but not always your thinking language.
International students
Move from rough documents to cleaner English submissions with structure, paraphrasing, grammar review, and originality checks in one place.
Researchers and graduate writers
Keep academic structure, wording quality, and originality in one workflow when your final output needs to sound precise and credible.
Bilingual creators
Turn ideas that start in your native language into natural English copy without bouncing between translation and rewrite tools.
Confidentiality & editorial standards
Your business drafts, customer proposals, and internal communications belong strictly to your team.
Zero model training on your data
Your drafts, emails, and translations are never used to train public AI models. Data is encrypted in transit and at rest with strict multi-tenant isolation.
Calibrated specifically for non-native professionals
Examples, register models, and workflow conventions are shaped for managers, engineers, and consultants who need confident English output without losing meaning.

Frequently asked questions
Everything you need to know before getting started.
Is Diglot good for international students specifically?
Yes — the whole thing is shaped around the international-student workflow. You draft bilingually, from your first language into English in one editor; grammar fixes come with the reason your L1 produced the error; and application documents like personal statements and SOPs get structure built for second-language writers. The Authorship Certificate also covers you against the false AI-detection flags that land on ESL students more often.
Can it help with my application essays and statement of purpose?
Yes. Personal statements, statements of purpose, scholarship essays, admissions writing — Diglot gives each of them structure prompts and register guidance for non-native English. It suggests and you decide; it doesn’t generate the essay for you, which is the point when an admissions office wants your actual voice.
Will Diglot protect me if my essay is flagged as AI-written?
Diglot keeps a signed, append-only record of how you wrote each document — your Authorship Certificate. If a detector flags your work by mistake (and it happens to non-native writers more than most), that record is tamper-evident evidence of your process, and it holds up better than a Google Docs edit trail.
Is there a free plan for students?
Yes. The free plan covers bilingual editing, grammar, translation, and paraphrasing. If you’re writing a long thesis or a stack of applications, Spark ($19/mo) and Pro ($34/mo) raise the word quotas and add the full Authorship Certificate and premium models.
Does it support my first language?
Six first languages are modeled deeply with contrastive grammar data — Korean, Chinese, Japanese, Spanish, Russian, and Arabic — and another fourteen have partial coverage. Drafting and translation work with any pair; the L1-aware explanations are sharpest for the six deeply-modeled languages.

International students need three things at once: bilingual help, real learning, and academic-integrity safety — because they are also the most likely to be falsely flagged as AI cheats. Here are ten tools judged on the axes that actually matter.
A statement of purpose is a focused academic argument that you are ready for a specific program — not a life story. For international applicants, the winning SOP is specific, program-tailored, and written in clear, natural English. Here is how to write one.
Writing in English when it's not your first language is hard — but not because your ideas are weak. Here are 7 practical strategies to write faster, clearer, and more confidently.

Methods and Data Sources
The study draws on a panel of 42 jurisdictions observed quarterly between 2019 and 2025.
Where a jurisdiction changed its reporting basis, the earlier series is retained and flagged rather than silently rebased. Two cases required manual reconciliation (Meyer, 2019).
Limitations
Quarterly reporting hides within-quarter variance, so short shocks are smoothed. The panel is also unbalanced after 2023, when three jurisdictions stopped publishing.
International students carry a writing load domestic students never see: turning out high-stakes English — application essays, statements of purpose, coursework, a thesis — in a language that isn’t their first, while detectors flag non-native English at rates native speakers rarely hit. Most writing tools were built for native speakers chasing polish, so they read an international student as a careless native instead of a capable person working across two languages. Diglot starts from that reality.
You draft in your first language and cross into English in the same editor, source held in view. Each grammar correction comes with the reason your L1 caused it — a Chinese applicant’s SOP that reads translated because the tense keeps flattening, say — so the fix carries into next semester’s essays instead of resurfacing every time. Application documents get structure and register guidance meant for second-language writers.
And every document you write is sealed into an Authorship Certificate, so a wrongful AI flag on the essay that decides your admission, or a grade that touches your visa standing, is something you can answer with proof. Free to start, with plans that stretch to thesis length.
