The material says
The proposal introduces a constraint-aware approach that preserves flexibility while reducing operational risk.
You understand more than you use
Use the language you already understand.
Take useful phrases from real content and use them in your own writing and speech.
Read articles, documentation, and PDF files or watch YouTube. Save useful phrases and return to them when you write or speak.
Start with a ready-made material. You do not need a separate course.
Familiar?
You understand the sentence, but would not write it yourself?
Precise wording feels clear when someone else writes it. In your own text, you fall back on simpler words.
You write
This approach is good because it is flexible and has fewer risks.
You already understand the phrases you need. Active Dictionary helps you start using them.
One phrase, step by step
How a phrase from a material becomes part of your language
See the whole path at once: notice a phrase, save it, and decide how to use it in your own writing.
- 1
Notice
You find a useful phrase
The phrase radar helps you notice it in a text, PDF, or captions.
- 2
Save
You save it to your dictionary
The example from the original material stays with the phrase.
- 3
Return
Writing selects the phrase for a matching task
The saved phrase appears under My Phrases when it matches the topic of the task.
- 4
Decide
You decide whether to use it
Insert it, change it, or skip it. You still write the final text.

What is different
Active Dictionary does not write for you
It helps you find a useful phrase, save it, and try it in your own writing or speech.
A generator writes a draft
It creates new text for you. That is useful, but it does not make a new phrase part of your own language.
An editor checks finished text
It improves what is already written, but does not connect it to phrases from your materials.
Cards help you review
Use them when you want extra practice with saved words and phrases. They are optional.
Active Dictionary helps you use new phrases
A phrase follows a clear path: material → personal dictionary → Writing or Speaking.

What to know before you begin
Can I try Active Dictionary without signing up?
Yes. Open the public library and choose a material. You will need an account for your own project, saved results, and personal trainers.
What level is the product designed for?
It is mainly for people at B1 and above who already read and watch content in the language they are learning.
Which materials are supported?
You can work with texts, PDF files, and YouTube videos that have available captions.
How is the AI expert different from a general chat?
It works beside the open material and can use a selected passage as context. You do not need to paste the source into every new chat.
Are there limits for PDF?
Automatic OCR in the current version is designed for PDF files of up to 50 pages. The exact experience depends on the file structure and its text layer.
