Classes and students

A teacher account makes classes, hands out your students' logins and shows you how each student is getting on. The lab isn't a course and doesn't grade anyone: think of it as a practice partner that never runs out of material.

What a teacher gets

A teacher account, which is also an ordinary learner account, so you can try everything your students will see.
Classes, each with a three-character code that ends every student's username in it, and a number of active classes and students per class to work within; archive a class at the end of term.
Students' logins made from first names or nicknames (no surnames), with easy passwords such as panda-river-42 on printable login cards, or as a file for a spreadsheet. A lost card takes a click to replace.
Lists for the class: paste the week's characters or words once, and every student finds them in Tones, Dictation and Write, on the review schedule as their own; change them any time.
Progress: for each student, when they last practised; clips, drills and conversations in the last 7 and 30 days; how often they were right (comprehension, tones, pinyin, and characters written from memory); the words they've met; and a four-week trend. The table saves as a CSV.
Their conversations with the AI partner, readable in full with the debrief, so you can give feedback; the lab tells students that their teacher can read them.
Safety flags from the lab's own conversation log: any exchange where the partner changed the subject, or stopped the conversation and showed where to get help, with a mark-reviewed button.

A teacher's view of a class's progress: each student's practice, accuracy and words

Students under 18

Under-18s use the lab only as students of a teacher, never through the sign-up form. Before you make a login for a student under 18, a parent or carer must have agreed; the lab asks you to confirm this each time you add students, and records that you did. A consent note you can send is in the teacher's guide.
Students' voice recordings are never kept.
Students get the fast AI model for clips and the partner, under classroom rules that are set on the lab's server and can't be switched off: everyday subjects only, no personal details asked for, and a conversation that stops and shows where to get help if anything a student says suggests they're in danger.
Students can see what their teacher sees, in their own Settings.
Each student reaches only their own work, and a student sign-in lasts a day, because so many school devices are shared.

Teacher trial places

Are you a teacher or tutor who'd like to use this with your students? A limited number of teacher trial places are open now: write to hello@tinglilab.com with “teacher” in the subject.

Teacher accounts aren't self-serve yet: the first teachers are engaged personally, so that their needs shape the teacher features before teacher or school accounts become self-serve. During the trial, one class of up to 5 students is free.

Students can use the free tone lab at tinglilab.org without any account.

The teacher's guide explains it all, step by step: making a class, the login cards, the first lesson, day-to-day fixes, progress, and what keeps the AI partner safe.
