Writing in a second language usually means switching between a translator, a grammar checker, a paraphraser, and a citation tool. Diglot keeps them on one document.
Unlike generic translators that flatten your nuance, Diglot preserves your academic tone and personal writing voice across languages.
Translation, rewriting, grammar, and citations share one document instead of living in separate tabs.
Built for ESL writers who need a clear, consistent drafting and revision workflow.
Keep drafts, translations, citations, and revisions together as your document grows.
Example workflows, not customer reviews. Each one uses features that are available today.
A PhD student writing in their second language drafts a section in their first language, translates it in the same document, and checks the grammar before it goes to a supervisor.
A researcher picks the journal’s citation style from 10,852 CSL styles and formats the reference list without leaving the draft.
A professional who writes reports in English rewrites a paragraph in a more formal tone, then asks Cowriter to tighten it without changing the meaning.

How payment confirmation, subscriptions, refund terms, and support work.
Your documents and drafts are not used to train public AI models. We use encryption in transit (TLS 1.2+) and at rest, least-privilege access controls, and publish the processors that handle data in our Privacy Policy.
You can cancel renewal through Settings → Billing or by contacting support at least 24 hours before renewal. Cancellation takes effect at the end of the paid period; your documents stay in your workspace.
Start on Free without a card to see whether the workflow fits. If you upgrade, a 14-day money-back guarantee applies in every country: email support@diglot.ai within 14 days of your first payment for a paid plan for a full refund, no reason required. Renewals are not covered; statutory rights such as the EU, EEA and UK withdrawal right still apply. Full terms are in our Terms of Service.
General chatbots lack citation management, long-form document coherence, and academic tone memory. Diglot is tailor-built for professional bilingual authors.
Everything you need to know about our plans, limits, and billing.
Yes. Cancel renewal through the billing provider that handled your payment, at least 24 hours before the renewal date. The portal shows the renewal date, invoices, and cancellation option.
Your documents stay yours. Free includes up to 10 documents; Spark, Pro, and Max unlock unlimited storage. Every plan keeps version history: 7 days on Free, 30 on Spark, 90 on Pro and Max.
Spark is ideal for regular essays and client work with strong limits. Pro adds Native-tier AI quality, deeper Cowriter limits, and HTML export.
They are quality tiers for AI modules — from fast open models (Fluent) to premium mid-tier (Smart) and flagship routing (Native). Higher tiers keep nuance for academic and professional English.
Annual is billed once per year at the total shown ($190/yr for Spark, $340/yr for Pro, $790/yr for Max). That is 10 monthly payments — a 16.7% saving, or two months free — and we display an effective monthly price for comparison.
Yes. Upgrades go through checkout; your workspace and documents stay in place, and higher limits apply immediately after the new subscription is active.
You keep your documents within Free limits. If you are above a limit after downgrading, export or archive what you need first — support can help if you are unsure.
Not as self-serve checkout yet. Email us at support@diglot.ai with seats, VAT invoices, or department needs and we will point you to the right option.
Move from rough bilingual drafts to clearer English in one connected writing workflow.
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).
Quarterly reporting hides within-quarter variance, so short shocks are smoothed. The panel is also unbalanced after 2023, when three jurisdictions stopped publishing.
