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.

Spark and Pro expand the same workflow
Free lets you explore bilingual drafting with starter limits. Spark ($19/mo) adds higher quotas and Smart-tier AI. Pro ($29/mo) adds Native-tier quality, academic export, desktop, and API.
Built for recurring English writing
Diglot is most valuable when you write in English regularly for school, work, or publishing and want fewer context switches every time.
Works in the browser across devices
Use the same workflow on desktop and mobile anywhere you can open the web app, without installing another editor.
Supports the practical writing loop
Start from a free plan, build a repeatable workflow, and upgrade only when your volume or feature needs grow.

Pricing FAQs

Answers about billing clarity, plan fit, and how to choose without guessing.

How should I choose between Free, Spark, and Pro?

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.

Does every paid plan support the connected writing workflow?

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.

Can I start on Free and upgrade later?

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.

Which plan is best for students or academic work?

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.

Which plan is best for professional writing?

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.

Can I cancel my subscription at any time?

Yes. You can cancel at any time, and the change takes effect at the end of the current billing period.

Is Diglot secure enough for work and study?

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.

Do I need to install a separate desktop app to use my plan?

No. Diglot runs in the browser, so your plan works anywhere you can open the web app on desktop or mobile.
