Trinka

What is Trinka?

Trinka is an AI platform designed for researchers, students, and professionals in the medical and technical fields, aimed at assisting with English writing and preparing manuscripts for submission. Unlike grammar tools that are primarily used for everyday emails, it focuses on checking academic tone, technical terminology, complex grammatical structures, style guidelines, the quality of citations, and overall consistency throughout the text.

The products include cloud-based editors, browser extensions, Windows applications, Microsoft Word plugins, tools for checking Word and LaTeX files, as well as APIs, JavaScript SDKs, and options for local deployment aimed at organizations.

Academic grammar and language checking

Trinka checks spelling, subject-verb agreement, articles, prepositions, tenses, syntax, word choice, and punctuation, and provides more formal and clear suggestions based on the conventions of academic and technical writing.

The suggestions may not be suitable for all academic contexts. Authors should review them one by one, avoiding any changes to the professional meanings, variable definitions, or references to the original text.

Lite and Power modes

Basic primarily uses the Lite mode, while the paid versions offer advanced writing modes such as Lite and Power. The Power mode provides more in-depth suggestions regarding academic style and expression, making it suitable for non-English native speakers who are preparing their manuscripts.

Style Guide specifications

The paid version supports adjustments in accordance with style guides such as APA, AMA, ACS, AGU, and IEEE, to help standardize numbers, abbreviations, capitalization, and wording.

Tools cannot cover all the detailed rules of each journal; it is still necessary to refer to the Author Guidelines before submitting a manuscript.

Full text Proofread File

Users can upload Microsoft Word or LaTeX files for a full proofreading. The system does its best to preserve the formatting, tables, structure, and LaTeX code, and provides an editable file with tracking changes in the paid version.

Basic allows up to 4 files per month and the results are read-only; Premium permits up to 10 files, Premium Plus allows up to 20 files, and Confidential Data supports up to 50 files – the usage is calculated based on credits.

The annual statement applies to 120 files for Premium, 240 files for Plus, and 600 files for Confidential.

Consistency check

The Consistency Check identifies inconsistencies in English and American spelling, hyphens, numbers, symbols, spacing, and terminology throughout the text; it is suitable for long papers, dissertations, and documents created through collaborative work.

Technical spelling and inclusive language

The platform is able to identify proper spelling and to indicate expressions that may be too informal or not suitable for formal contexts. Specific terms should still be confirmed in accordance with the standards of the respective discipline, community, and journal.

Paraphraser: Rewrite

The rewriter helps to improve the clarity and expression of sentences. Basic version offers only the standard mode, while the paid versions provide all modes.

Rewriting must not be used to conceal plagiarism; when citing others’ ideas, the source still needs to be indicated.

AI Writing and ask

AI writing can generate, expand, and optimize text based on the context. Basic offers 5 instances per month, Premium offers 25 instances, Premium Plus offers 1000 instances, and Confidential Data offers 3000 instances.

The generated content may include fictional documents, data, or conclusions. Paper authors must verify the facts and comply with their institution’s AI disclosure policies.

File Translation

Premium Plus and Confidential Data offer file translation in over 30 languages; currently, up to 50,000 characters can be processed per 5 credits. Specialized terms, statistics, and citations must be checked manually.

Quote quality inspection

Citation Checker identifies risks such as retractions, unverified sources, suspected predatory journals, duplication, outdated information, and excessive citation of a single journal, and it verifies references using data from sources like Crossref.

The analysis of scores is free; a full report requires 1 credit for every 30 citations. The fact that no records are found in the database does not mean that the corresponding literature does not exist – the author should verify this using the DOI and the publisher’s information.

Citation formatting

Citation Formatter assists in organizing references according to the desired style; 1 credit is required for every 30 citations. Premium Plus and Confidential Data plans include formatting for 600 citations per year.

Journal recommendations

Journal Finder matches journals to paper topics based on a large database of publication records; it shows similar papers, publication trends, options related to open access and impact factors, and alerts to potential predatory journals.

Recommendations do not guarantee that the manuscript will be considered for publication or accepted. It is also necessary to check the journal’s scope, fees, review policies, and official website.

Publication Readiness and technical checks

Trinka offers assistance with preparing submissions, ensuring technical consistency, and checking the quality of documents, helping to identify formatting and style issues beyond language problems. Automatic reports cannot replace journal editors or professional human editing.

Plagiarism check

For Basic and Premium plans, credits are required to access the standard plagiarism check; Premium Plus includes both the standard plagiarism check and AI-based detection, up to 240 pages per year, while Confidential Data allows up to 1000 pages per year, along with one Advanced report per month.

Each page is calculated as 250 words.

Similarity does not constitute proof of infringement, nor can it be used directly to punish students. It is necessary to examine the source of the match in order to determine whether there is citation, use of common expressions, or actual copying.

AI content detection

The AI Detector consumes 1 credit for every 5,000 words; the Plus and Confidential tiers allow for combined use between standard plagiarism checking and AI detection. The detector may give incorrect results regarding written text that was created by humans or in a language that is not the speaker’s native language, and it should not be used as the sole evidence of academic integrity.

Basic free version

The basic price is 0; no credit card is required, and there is no expiration date. It includes 5,000 words of writing assistance per month, 4 document proofreading sessions, 5 AI-generated writing attempts, 4 free credits, and 1 free plagiarism check.

Free credits expire each month, while additional credits purchased remain valid indefinitely. Once the monthly limit is reached, one must wait for a renewal, purchase more credits, or upgrade.

Premium

Premium offers full writing capabilities, all advanced modes, a style guide, native Word plugins, up to 10 full-text revisions per month, 25 AI writing sessions, 10 credits, and 2 free plagiarism checks per month.

Standard plagiarism checks, AI-based detection tools, and citation tools are charged separately based on credits. The amount for the Premium version is displayed dynamically on the official website’s payment page; the actual amount to be paid should be that shown on the settlement page.

Premium Plus

Premium Plus includes all the features of Premium, plus 20 documents for proofreading per month, 1,000 AI writing sessions, 20 credits, document translation services, 240 pages of standard plagiarism checking or AI detection per year, and 600 citations formatted.

It is suitable for researchers who frequently prepare submissions and need original reports. The current specific amount should be as indicated on the official settlement page.

Confidential Data

Confidential Data is designed for sensitive, regulated, or proprietary content; it offers offline grammar checking, immediate data deletion, no AI training, 50 files per month, 3000 AI writing sessions, 50 credits, 1000 pages of reports per year, and one Advanced plagiarism check per month.

The page currently shows $300 per year and $41.67 per month; these amounts are not consistent with each other. The actual price to be paid shall be based on the settlement page and the contract.

Privacy and Compliance

Regular paid data offers enhanced privacy along with automatic deletion after 90 days; Confidential Data ensures that the data is deleted immediately after processing, is not stored and is not used for training, and it complies with various standards such as SOC 2, HIPAA, ISO 27001, GDPR, and the EU AI Act.

Organizations should still request the relevant certifications, DPA, and deployment instructions; they cannot rely solely on marketing identifiers to determine compliance in all scenarios.

Teams and institutional plans

Team plans are typically designed for at least 6 users, and they offer usage analysis, user management, customization, white-labeling options, APIs, SDKs, and the possibility of local deployment. The institutional version also provides LMS, SSO, DocuMark for tracking the writing process, as well as a cost-free trial period.

DocuMark Academic Integrity

DocuMark records the processes of inputting, pasting, modifying text, and generating content using AI; it provides analyses regarding effort invested, ownership of the work, and its source of creation, thereby assisting teachers in making informed decisions. It should not replace the procedures for handling complaints and ensuring academic integrity.

Developer APIs and SDKs

The Trinka developer platform offers a Grammar Checker API, TrinkaJS pre-built components, a Proofread File API, a Reference Quality API, and an AI Detection API. Companies can choose between cloud APIs, JavaScript SDKs, or on-premises solutions.

The Proofread File API can return Word or LaTeX files with revision marks. Prices, rates, and data processing requirements are subject to the terms of the developer contract.

Cancellation and refund

Users can disable automatic renewal at any time, and the subscription benefits remain valid until the end of the cycle. According to the official guidelines, no refund is provided in case of cancellation.

The additional credits purchased remain intact even after cancellation.

GitHub and the open-source status

Trinka’s core grammar model, writing platform, detector, and institutional services are not open-source products. A search on GitHub in real time did not reveal any complete official source code organized as confirmed by the official website.

The warehouse with the same name, Trinka, as well as other similar brands belong to third parties and cannot be used as official evidence of open source status. Such directories should be labeled as closed-source SaaS.
