What Trinka AI is

Trinka checks text as you type on academic platforms such as Authorea and Typeset and on most other websites, flagging complex grammar, vocabulary, tone, and conciseness issues for formal writing. It also corrects biased or vague wording and supports a personal dictionary.

Permissions and privacy

Page access

Real-time correction requires reading the text fields you type into, and the listing says it works on most websites. Restrict Chrome site access to the academic platforms and editors where you write, and keep it off pages with credentials or private messages.

Data notes

The listing discloses authentication information, personal communications, and website content. The listing says data is encrypted and not shared with third parties, and Crimson AI's plugin page says text is not stored. It also sells a separate Confidential Data plan aimed at sensitive content.

Pricing

Extension included in the free Basic plan; paid Premium and Premium Plus plans. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
