Pricing for sustained writing

Spend your quota on writing,
not on switching tools.

Every paid plan is built around the paper-writing flow: long projects, frequent compiles, version review, extra Credits, and team-friendly deployment.

Research-grade editor

Section writing, LaTeX compile, references, and AI suggestions in one place.

Sustained projects

Version history, restore points, and team collaboration suit medium- and long-term papers.

Controlled deployment

Private deployment and quota controls for universities, labs, and enterprises.

Notes

When does a membership make sense?

Once you're in steady writing mode, compiling, polishing, version diffs, and extra Credits become high-frequency actions. A membership doesn't add features — it keeps these actions effortless.

When is a membership a good fit?

If you're in steady writing mode and need continuous compile, batch polishing, version review, or team collaboration, a subscription is more convenient than ad-hoc credit top-ups.

FAQ

FAQ

Will it auto-renew after the trial?

No. Trials never auto-charge — to keep using the product, subscribe to a plan.

What if I run out of credits?

Buy a credit pack on demand — packs never expire and work for batch polishing, draft generation, or last-mile changes.

What's the difference between yearly and monthly?

Both plans have the same monthly quota (2000 Credits). The yearly plan is cheaper per month (~¥25/mo vs ¥39/mo) — better for long-term users.
