Visible to your parentThis interaction and the learner's revision are part of the activity record.
The learning loop
Support at the moment
understanding is forming.
The tutor is part of the curriculum experience, not a separate chatbot. It responds with the smallest useful step, lets the learner act, gives immediate feedback, and checks for independent transfer before moving on.
Converse
Respond in a guided real-world exchange that adapts naturally without outrunning the learner's level.
Notice
Review a transcript with a small number of focused notes on meaning, grammar, pronunciation, and complexity.
Return
Retry the moment, practice difficult phrases, and revisit vocabulary through spaced conversation.
Designed in depth
What the language tutor
is being built to do.
Each capability connects to a defined learning purpose, parent-visible evidence, and age-appropriate boundaries.
Guided roleplay
Practice introductions, cafés, travel, family conversations, interviews, storytelling, and Knowledge Tree-specific scenarios.
Responsive conversation
Adjusts its speed, vocabulary, sentence length, and follow-up questions to the learner's demonstrated level.
Pronunciation feedback
Highlights words or sound patterns that affected clarity and gives a model, retry, and comparison.
Listening modes
Offers natural, slowed, chunked, replay, and transcript-after-listening options without making support permanent.
Vocabulary in context
Draws scheduled vocabulary into conversation and revisits fragile words through spaced retrieval.
Grammar that serves meaning
Explains a correction in the context of what the learner was trying to communicate.
Conversation transcript
Lets the learner and parent review turns, feedback, new words, corrections, and growth over time.
Cultural notes
Adds reviewed context about register, politeness, conventions, and regional differences where appropriate.
Spoken, signed & classical modes
Supports major spoken languages, English for multilingual learners, visual ASL practice, Latin, and Knowledge Tree-aligned Greek and Hebrew pathways.

A coach inside the work
Immediate guidance.
Durable evidence.
Help arrives while the learner can still use it. The result is not just a corrected answer or polished submission; it is a visible record of the thinking, feedback, revision, and independent check that followed.
- 01Context-aware
The tutor sees the assignment, objective, rubric, allowed resources, and relevant Knowledge Tree roots.
- 02Proportionate
It begins with the smallest useful nudge and increases support only when the evidence calls for it.
- 03Reviewable
Parents can see the learner's work, tutor guidance, changes, and resulting mastery evidence in one timeline.
Parent-visible by design
Automation helps.
You remain in charge.
Families decide when the tutor appears, how much it may do, what gets recorded, and when a human should step in.
Conversation boundaries
Parents choose approved scenario categories, session length, free-conversation access, and learner age settings.
Support level
Allow translations, sentence starters, visible vocabulary, slow speech, or target-language-only practice.
Recording privacy
Microphone and camera access are off outside speaking or signing activities. Audio and ASL video are not retained by default after analysis.
Progress focus
Choose intelligibility, vocabulary, grammar, listening, spontaneous speech, or a Knowledge Tree objective as the priority.
One tool, changing expectations
Grows with the learner.
Never talks past them.
Understand and respond
High-frequency words, modeled phrases, visual supports, short listening, and predictable exchanges.
Connect familiar ideas
Longer answers, familiar scenarios, questions, narration, and growing control of core grammar.
Sustain the exchange
Unscripted follow-ups, varied time frames, explanation, comparison, and authentic listening.
Communicate with nuance
Register, idiom, persuasion, interpretation, extended speech, and discipline-specific vocabulary.
See and sign the language
Receptive signing, handshape, movement, location, facial grammar, classifiers, fingerspelling, and expressive conversation.
◎Useful boundaries are
Responsible by default
Useful boundaries are
part of good teaching.
The tutor should be judged not only by what it can do, but by what it wisely refuses to do.
