Which plan is for whom
Pick the plan that matches the writing workload you repeat every week.
What the plans are really buying you
Diglot pricing makes the most sense when you need a connected workflow instead of a correction layer living in isolation.
Six workflow surfaces, priced by depth—not locked by tool
The same stack on every tier; differences are quotas, AI tiers, and exports—use this grid once plan fit is settled.
Draft, refine, and rewrite English with AI support built for non-native speakers.
Translate, compare, and edit multilingual text in one writing workflow.
Catch grammar, spelling, and punctuation issues while you write in English.
Rewrite sentences, improve fluency, and keep your original meaning clear.
Scan content for overlap and protect originality before submission or publishing.
Start from ready-made structures for essays, emails, reports, and proposals.
Cryptographically signed proof you wrote your own text — defends against false AI-flag accusations.

Answers about billing clarity, plan fit, and how to choose without guessing.
Choose based on workflow intensity, not on feature curiosity alone. Free is for testing the workflow, Spark is for recurring translation and rewriting, and Pro is for heavier drafting plus originality review.
Yes. The paid plans are designed around the same connected workflow, with the main differences being usage depth, output volume, and how heavily you rely on the assistant and originality tools.
Yes. You can begin on the free plan, learn which Diglot workflows you actually use, and upgrade once your writing volume or output requirements grow.
Students who write frequently or need originality review will usually outgrow Free quickly. Spark covers recurring rewriting well, while Pro is a better fit for heavier drafting and submission-ready work.
Professionals who write regularly in English often land on Spark first. Pro makes more sense when the workload includes longer drafts, more frequent output, or higher-stakes documents.
Yes. You can cancel at any time, and the change takes effect at the end of the current billing period.
Diglot uses encryption, access controls, and standardized security practices to protect user data. The product is positioned as a secure browser-based workspace for recurring English writing.
No. Diglot runs in the browser, so your plan works anywhere you can open the web app on desktop or mobile.
Write in your language,
publish in English
Move from rough bilingual drafts to clearer English in one connected writing workflow.
