Trinka

Trinka - Content & Copywriting AI Tool

Grammar checking that knows technical writing.

Trinka corrects academic and technical prose with awareness of subject-specific terminology and style guides — APA\, IEEE\, ACS\, AGU — rather than applying general English rules that mangle domain language.

General checkers routinely flag correct technical terms as errors\, which is why researchers stop using them. The free tier gives 5\,000 words a month and never expires. The Confidential Data plan at $300/year adds offline checking and no AI training.
