Everything you need to know about our data security, subscription terms, and guarantees.
Yes. Your documents and drafts are never used to train public AI models. All data is encrypted in transit (TLS 1.3) and at rest (AES-256) with strict SOC2/GDPR compliance.
Absolutely. You can upgrade, downgrade, or cancel your subscription with a single click right from your settings. No dark patterns, no mandatory phone calls, no hassle.
We offer a 14-day money-back guarantee. If Diglot does not elevate your writing or save you hours of work, simply message our support team for a prompt, courteous refund.
General chatbots lack citation management, long-form document coherence, academic tone memory, and plagiarism protection. Diglot is tailor-built for professional bilingual authors.
Everything you need to know about our plans, billing, and trial limits.
Yes. You manage subscription through the billing provider that handled your payment. When the portal is connected, you will see renewal date, invoices, and a cancel button there.
Your documents stay yours. Free includes up to 25 documents; Spark and Pro unlock unlimited storage (Pro also adds version history).
Spark is ideal for regular essays and client work with strong limits. Pro adds Native-tier AI quality, plagiarism-safe paraphrase, deeper Cowriter limits, academic export, desktop app, and API access.
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.
Spark and Pro include similarity previews each month. Full 250-word page scans are purchased once in page packs that never expire for a full year ($12 for 100 pages, $39 for 400, $89 for 1000). Free only shows preview similarity.
Annual is billed once per year at the total shown ($190/yr for Spark, $290/yr for Pro, $790/yr for Max). We display an effective monthly price so you can compare plans fairly.
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.

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.
