For classroom teachers, grades 3 to 12

AI co-teacher and AI co-teaching for schools that works the room while you teach the small group

Most classes have one adult and thirty students. Coeducate takes the second seat: it coaches every student with hints while you work with the five who need you, then tells you in writing which step each student missed.

See pricing

From $89 a month per teacher. Student work is never used to train models.

The short answer

Two different products are sold as an AI co-teacher

An AI co-teacher either co-plans with you before class or works with your students during it. The first drafts lessons and never sees student work. The second tutors students and reports back. If your problem is that one adult cannot reach thirty students in a period, you need the second kind.

The co-planner

Works with the teacher before class. Adapts a lesson, writes practice and scaffolds, builds a rubric. Coteach (built around Illustrative Mathematics), Tutero's math co-teacher and MagicSchool are examples, based on how those vendors describe themselves.

Where it stops. It never sees what your students wrote, so it cannot tell you who is stuck tomorrow.

The in-class co-teacher

Works with students during the lesson. Each student solves and explains, the tutor asks the next question instead of giving the answer, and the teacher gets a card naming the broken step. This is Coeducate.

Where it stops. It does not plan your lessons, grade tests or read handwriting.

01 The six co-teaching models

Which co-teaching seat software can actually take

Special education and inclusion teams have used six co-teaching approaches for decades, as set out by Marilyn Friend and Lynne Cook. Here is a plain read on each one, with the second adult replaced by a tutor. Three work well, two work in part, and one does not work at all.

Model	How two adults run it	AI in the second seat	What the tutor does there
One teach, one observe	One adult teaches, the other records what students do.	Partly	Records each student's reasoning on the items they work. It does not watch the room.
One teach, one assist	One adult teaches, the other circulates and helps individuals.	Yes	Gives every student a hint at the same moment, instead of one student at a time.
Station teaching	Students rotate through stations, each adult runs one.	Yes	Runs the independent practice station and keeps the record from it.
Parallel teaching	The class splits in half and each adult teaches the same lesson.	Partly	Can carry the practice half of a split class. It does not deliver the lesson.
Alternative teaching	One adult takes a small group, the other keeps the large group.	Yes	Keeps the large group working on the day's items while you teach the small group.
Team teaching	Both adults lead the lesson together.	No	Co-leading a discussion needs a second adult. No software does this well.

One teach, one observe

Partly

One adult teaches, the other records what students do.

Records each student's reasoning on the items they work. It does not watch the room.

One teach, one assist

Yes

One adult teaches, the other circulates and helps individuals.

Gives every student a hint at the same moment, instead of one student at a time.

Station teaching

Yes

Students rotate through stations, each adult runs one.

Runs the independent practice station and keeps the record from it.

Parallel teaching

Partly

The class splits in half and each adult teaches the same lesson.

Can carry the practice half of a split class. It does not deliver the lesson.

Alternative teaching

Yes

One adult takes a small group, the other keeps the large group.

Keeps the large group working on the day's items while you teach the small group.

Team teaching

Both adults lead the lesson together.

Co-leading a discussion needs a second adult. No software does this well.

If you already co-teach with a special educator, the tutor does not replace that person. It frees them, because the large group keeps working while both adults pull students. The AI for special education teachers page shows how the same record feeds IEP progress notes.

02 The part one adult cannot do

You can sit with five students or circulate to thirty, not both

Picture a seventh grade period on adding integers. Six students did not get the warm-up, so you pull them to the back table. The other twenty-four start the practice set. Ten minutes in, a hand goes up, then three more. Every minute you spend walking over is a minute the small group sits still.

With a co-teacher in the room, the hands go to the second adult. With Coeducate, they go to the tutor, which asks each student a question about their own working rather than giving the answer. You stay at the back table for the whole block, and nothing that happened at the desks is lost.

The item

Find -7 + 4 and explain how you know.

What the student typed

"-11. You add 7 and 4 and it's negative because there is a minus."

A good co-teacher would kneel down, ask the student to show -7 on a number line and then move four steps, and write a note for you after class. The tutor does both. It asks the question first, so the student has a chance to fix it, and the note is waiting when you sit down at 3:15.

The same card runs Tier 2 groups on the math intervention software for middle school page, and the AI math tutor page shows what the student sees.

Session evidence card, grade 7, adding integers

Fixed example

Diagnosis

Adds the absolute values and keeps the sign of the first number

The student added 7 and 4 and attached the negative sign because the expression starts with a minus. Asked to start at -7 on a number line and move 4 to the right, the student landed on -3 and said that was different from the first answer. The student has not linked direction on the number line to the sign of each addend.

Next tutoring move / hint only

You started at -7 and moved 4 steps. Which way did you move, and does that make the number bigger or smaller?

Direction decides the sign

Model -7 + 4 on a number line, saying each step out loud.
Give three pairs where the student predicts left or right before calculating.
Ask the student to write when the answer keeps the sign of the larger absolute value, in their own words.

04 How it runs in one period

Four steps, and the teacher decides each one

1

Pick today's items

Use problems or a short passage from your own unit, textbook or exit ticket. There is no separate curriculum to adopt and no content library to follow.
2

Split the room

Pull your small group. Everyone else opens the tutor on a laptop or tablet and works the same items with hints, never the answer.
3

Read the cards by cause

After class, the cards group by misconception, so twenty-four sessions arrive as three or four piles with each student's words attached.
4

Plan tomorrow from the piles

Each card carries a three-step reteach. Pick tomorrow's small group from the biggest pile and export the dated record to CSV for MTSS or IEP notes.

Five questions to ask any AI co-teacher vendor

Our own answer follows each one, including where we come out short.

Does it work with students, or only with the teacher? A co-planner saves prep time but leaves you alone in the room. Ours works with each student during class.
Does it give answers? A tutor that hands over the answer is a homework machine. Ours asks the next question, and in Socratic mode it never gives the answer.
What do you get after class? A chat log is not a record. Ours returns a card per student naming the skill, quoting the student and suggesting a reteach.
What happens to student work? Ask whether it trains models. Ours does not.
What will it not do? Ours does not plan lessons, grade tests, read handwriting or teach phonics and decoding. If you need those, pair it with a tool that does.

06 Who uses it

Teachers who are the only adult in the room

Math teacher, grades 3 to 8

Fractions, integers and early equations, where a pulled group is the difference between catching up and falling behind. See AI for math teachers.

ELA teacher

Short written answers on a passage, where the card names the comprehension skill that failed. See the AI reading tutor.

Inclusion classroom

A special educator who visits two periods a day. The tutor keeps the rest of the class productive while both adults pull students.

Principal or coach

Cannot fund an aide in every room. The School plan covers up to 600 students for $2,088 a year. See AI tutor for schools pricing.

07 FAQ

Questions teachers ask about an AI co-teacher

Looking for a tool that drafts materials for you instead? The AI teaching assistant page compares both kinds, and the Khanmigo alternative for schools page compares us with a free student tutor.

What is an AI co-teacher?

An AI co-teacher is software that takes part of the second adult's job in a classroom. Some products co-plan with the teacher, drafting lessons and practice. Others work with students during the lesson, giving hints and recording what each student got wrong, while the teacher leads instruction or pulls a small group. Coeducate is the second kind.

Can AI be a co-teacher?

AI can take some co-teaching roles and not others. It can circulate to every student at once in a one teach, one assist setup, run one station in a rotation, and keep the observation notes. It cannot co-lead a lesson, manage behavior, notice a student is upset or share accountability for grades. Those stay with the adults in the room.

Will there be AI teachers?

Some private schools already market AI-led instruction with adult guides instead of classroom teachers, but public schools are not replacing teachers with AI, and no state licenses software as a teacher of record. The realistic near-term change is narrower: AI handles hints, practice and the first read of student work, and the teacher spends more time teaching.

Are teachers allowed to use AI?

Yes, in most US districts, within the district's AI and data privacy policy. Many states have published K-12 AI guidance, and districts usually require that any tool touching student data has a signed data privacy agreement. Check whether your district keeps an approved tool list before you put student work into any AI product, including ours.

How much does an AI co-teacher cost?

Co-planning tools usually have a free teacher tier with school plans by quote. Student-facing tutors are priced per student or per school. Coeducate publishes its price: $89 a month for one teacher with up to 60 students, $2,088 a year for a school of up to 600 students, and $1,290 a month for a district with PO billing.

What is the difference between an AI co-teacher and an AI teaching assistant?

The terms overlap and vendors use both loosely. In practice, a teaching assistant product usually works for the teacher, drafting materials and feedback. A co-teacher product works alongside the teacher with the students during class. Coeducate does the second job and then hands the teacher a written record of what each student did.

Which co-teaching model works best with AI?

Alternative teaching and station teaching fit AI best. In alternative teaching, the teacher pulls a small group while the rest of the class works with the tutor. In station teaching, the tutor runs one station. Both keep the teacher with the students who need an adult most, and both give the AI a bounded task it can do well.

Is an AI co-teacher safe for student data?

It depends on the vendor, so ask four things in writing: whether student work trains models, what is stored and for how long, whether the vendor signs your state data privacy agreement, and how deletion works. Coeducate does not use student work to train models, and the security page sets out our FERPA and COPPA posture for your review.
