AI Notice

Last updated: 18 October 2026

Hermeno uses several automated and AI-assisted services to support language-learning features.

Depending on the feature being used, the following technologies may be used:

• automated text recognition from images (OCR);
• automated translation;
• vocabulary extraction and identification;
• explanations;
• example sentences;
• vocabulary enrichment;
• quiz generation;
• interactive AI-assisted speaking and pronunciation practice.

Google Cloud Translation may be used for automated translation, particularly when corresponding content is not already available in the Hermeno dictionary or an existing translation cache.

Google Gemini may be used for OCR-assisted functions, additional AI-assisted learning features, and vocabulary enrichment.

User-provided text, words, and, where applicable, images may be transmitted to the external service required for the relevant function.

Translation results may be stored in a shared cache and reused for subsequent requests. This can reduce repeated external processing, improve response times, and reduce resource consumption.

Stored translation results may subsequently be processed automatically for further vocabulary enrichment. This processing may take place asynchronously and may process multiple words together.

Different processing steps may use different technical services. In particular, the use of automated translation does not necessarily mean that the content is processed by a generative AI model.

AI-generated and automatically generated content may occasionally be incomplete, inaccurate, outdated, or unsuitable for a particular context. It is provided as a learning aid and should not be treated as professional, legal, medical, financial, or other expert advice.

AI-generated vocabulary suggestions from imported text are presented to the user before being added to the personal vocabulary collection. Users remain in control of which items are saved.

Users should review AI-generated translations, explanations, examples, and quiz content before relying on them.

Teacher Area and AI-assisted live quizzes

Teacher Area access is limited to authorized accounts.

For live-quiz authoring, teachers may provide vocabulary terms manually or use the vocabulary scanner to identify isolated vocabulary candidates from an ordinary lesson or reading page.

AI can generate complete draft quiz questions from supplied terms. A teacher may alternatively write a question manually and either provide the answer choices directly or ask AI to generate or complete answer choices and identify the correct option.

Generated questions remain editable and should be reviewed and confirmed by the teacher before use.

AI Live Speaking

When AI Live Speaking is used, microphone audio may be transmitted to Google AI services for live speech transcription, conversational response generation, and pronunciation analysis.

Depending on the active speaking engine, Hermeno may process the user's speech through a live transcription pipeline and may use Google Gemini for transcription, conversational AI processing, and pronunciation analysis. Google Cloud Text-to-Speech may be used to generate spoken responses.

During an active speaking turn, Hermeno may temporarily buffer audio and conversation text in memory so that the live conversation and pronunciation analysis can be performed.

The current Hermeno application data model does not contain persistent fields for storing raw microphone audio or a complete conversation transcript. Derived information, such as session feedback or pronunciation-analysis evidence, may be stored with the corresponding live-speaking session.

Processing or retention performed by an external provider is governed by that provider's applicable terms, technical configuration, and data-processing practices.

For further information about the processing of personal data, please see the Hermeno Privacy Policy.

AI Credits and Learning Rewards

Some AI-assisted or external-provider operations may be governed by free daily allowances and/or AI-credit costs. The applicable values are centrally configured and may be adjusted as Hermeno's services and operating costs evolve.

Users may earn credits through qualifying learning activity. The current model rewards eligible vocabulary-review progress and qualifying quiz completion, subject to daily limits.

Rewarded advertising is not part of Hermeno's current active product. AI credits are currently earned through qualifying learning activity rather than advertising.

Vocabulary scanning

For vocabulary scanning, Hermeno instructs the AI service to return isolated lexical items rather than a transcription of the submitted page. The application validates the returned structure before using it.

Publisher-prepared vocabulary lists, glossaries, indexes and similar compiled vocabulary collections are not supported and are intended to produce a rejection result instead of extracted vocabulary.

Images are submitted only for the requested scan workflow. Hermeno does not persist the source-page image or source-page transcription as vocabulary-import data, although processing by the external AI provider remains subject to the provider's applicable terms.

AI-generated educational illustrations

Some educational illustrations in Hermeno have been generated using Google Gemini. These visuals support vocabulary learning and other educational activities.
