AI teaching assistant and AI assistant for teachers that works with the student

Most AI assistants help you write. This one sits with each student during practice, then tells you which skill broke and why, in the student's own words.

The short answer

What an AI teaching assistant should take off your desk

An AI teaching assistant is software that does part of a teacher's work. Most products on the market help on the teacher's side: they draft lessons, quizzes and feedback from material you already have. Coeducate works on the student's side. Students type their working on your problems, the tutor coaches with hints rather than answers, and you get a card naming the misconception, the evidence and a five-minute reteach. Use a planning assistant for documents. Use Coeducate when you need to know what each student understands.

Plans start at $89 a month for one teacher and 60 students. A School plan covers 10 educators and 600 students for $2,088 a year.

Teacher at her desk in an empty classroom after the last lesson

01 The missing half

A teacher tool with no student in it

Lesson plan drafting, rubric generation, feedback drafts, parent letters. These are real and they save real hours. They also all operate on material the teacher already has, so they cannot tell you anything you did not already know about a student.

The hardest part of teaching 140 students is not producing documents. It is knowing, at four in the afternoon, which of them confused the base of a percentage and which just slipped on a multiplication. An assistant that never meets a student cannot help with that, however good its prompts are.

Teacher-side assistant

  • Drafts plans, rubrics and letters
  • Rewrites your material at other reading levels
  • Suggests likely misconceptions in general
  • Knows nothing about your actual students

Coeducate, both sides

  • Coaches the student through practice with hints
  • Names the misconception this student has
  • Writes the per-skill record for the teacher
  • Plans tomorrow from that class's real answers

Read it as written. For lesson planning the teacher-side tools are cheaper and broader, and two of them cost nothing. Coeducate does not draft lesson plans or grade essays, and it is not trying to. It is the assistant for the period after the lesson, when you need to know who has the idea and who does not. Price detail for each vendor is in MagicSchool Enterprise pricing, SchoolAI pricing for schools, Brisk Teaching pricing for schools and Khanmigo cost for schools.

03 Through the week

What it takes off the desk, in order

Before the lesson

  • Predicts the misconceptions this topic usually produces
  • Suggests the hint ladder for the hardest item
  • Flags who struggled with the prerequisite last week

During the lesson

  • Coaches individual students with hints while you take a group
  • Answers the eleventh identical procedural question
  • Keeps early finishers working on a harder version

After the lesson

  • Names the misconception in every piece of typed work
  • Writes the per-skill mastery read with evidence
  • Groups the class by fault line for tomorrow

Everything in the third column is work teachers already do badly, not through lack of skill but because there are 140 students and one of them.

04 Example output

What the assistant hands you after one wrong answer

The item (grade 7, from the teacher's own set)

A $40 jacket is marked up 20 percent, then put on sale at 20 percent off. What is the sale price?

The student wrote

"$40, because the 20s cancel out"

A planning assistant can tell you that percent change is a common trouble spot. It cannot tell you that this student computes a single percentage correctly and fails only when the base changes. That difference decides the reteach.

The tutor asks for 20 percent of $48, the student finds $9.60, and the card records both the slip and the recovery. The detail of each step is on how the session loop works.

Session evidence card, grade 7 percent change

Fixed example

Diagnosis

Treats percent change as additive, not multiplicative

The student assumes a 20 percent rise and a 20 percent fall cancel, because both are 20. The second percentage is taken of the new price, $48, so the sale price is $38.40.

Next tutoring move / hint only

Twenty percent of $40 is $8. What is twenty percent of $48, and why is that a different number?

Skill mastery read

Percent of a quantity

Secure
84%

Computed 40 + 20% = 48 correctly before the reasoning broke down.

Successive percent change

Not yet
22%

Says the 20s cancel out, applying both percentages to the same base.

Choosing the base of a percentage

Developing
41%

Found $9.60 after the hint, needed it once.

Checking a result for reasonableness

Developing
55%

Noticed the answer looked wrong but kept the first guess.

Teacher note

Single percentages are secure. The gap is which number each percentage is of, so any multi-step markup or discount problem will fail until that is fixed.

Reteach in 5 minutes

Same percent, different base

  1. Put $40 and $48 side by side and ask for 20 percent of each.
  2. Have students say aloud which number each percentage is of.
  3. Repeat the jacket problem, writing the base under every step.

05 For paraprofessionals and cover

The adult in the room is not always the subject specialist

A paraprofessional supporting a small group needs to know what each student is stuck on, in language they can use. A substitute covering a subject they do not teach needs a specific target and a script for the next move, not a worksheet and a lost period.

Both get the same artifact the class teacher gets: the named misconception, the next question to ask and the five-minute activity. Special education teams use the same record for IEP progress notes, as the AI for special education teachers page explains. Teachers with no second adult at all use it as an AI co-teacher that keeps the large group working while they pull a small group.

Support group brief, generated from the last session

Group A, 4 students

Base confusion in successive percentage change.

Ask: twenty percent of forty is eight. What is twenty percent of forty-eight?

Group B, 2 students

Percentage to decimal conversion not secure.

Ask: what does the percent sign mean? Show me 20 percent as a fraction first.

Group C, 1 student

Method correct, arithmetic slip in one multiplication.

Ask: check your second multiplication only. Everything else is right.

Nobody wrote this brief. It is the class view of the previous session's cards, grouped by fault line.

06 Price

What an AI teaching assistant costs for one teacher and for a school

A teacher-side assistant is priced per teacher, because the teacher is the only user. A student-side assistant runs a session for every student, so it costs more per teacher and covers more work.

The fair comparison is not price per seat. It is what you get back: a stack of drafts, or a record of what every student in the group understands. Plenty of schools buy both. Full plan detail is on the AI tutor for schools pricing page.

07 Being straight about it

When a planning assistant is the right purchase and we are the wrong one

  • Your bottleneck is paperwork. If the hours go into lesson plans, newsletters and rubrics, a teacher-side tool saves more of them, and some cost nothing.
  • You teach essays, science or history. Coeducate covers math and reading comprehension. It does not grade writing or lab reports.
  • Students write by hand only. The tutor reads typed working. A class that never works on a device will not get cards.
  • You want a content library. We bring no courses. Students work your problems, which is the point, but it means you supply them.

08 FAQ

Questions teachers ask about AI teaching assistants

What is the best AI teaching assistant?

The best AI teaching assistant depends on which half of the job you want help with. For drafting lessons, rubrics and parent emails, MagicSchool, Brisk, Khanmigo's teacher tools and ChatGPT for Teachers all do well. For knowing what each student actually understands, you need an assistant that works with the student, such as Coeducate, which tutors over your own assignments and writes a per-skill record for the teacher.

Is there an AI teaching assistant?

Yes, several kinds. Teacher-side assistants generate plans, quizzes and feedback drafts from material the teacher supplies. Student-side assistants tutor students directly and report back. Coeducate is the second kind: students type their working on your problems, the tutor coaches with hints instead of answers, and the teacher gets the named misconception, the evidence and a reteach plan.

Can AI be a teaching assistant?

AI can do part of a teaching assistant's job well: coaching one student through practice while the teacher works with a group, answering the same procedural question for the eleventh time, and writing up what each student got wrong. It cannot build relationships, manage a room or make the instructional decision. Those stay with the teacher, who reads the evidence and decides.

Is there a free AI teacher assistant?

Yes, for the teacher-side half. Khanmigo's teacher tools cost nothing, ChatGPT for Teachers is free for verified US K-12 teachers through June 2027, and MagicSchool and Brisk have free tiers. What is rarely free is the student side, because every student session costs money to run. Coeducate is paid, from $89 a month, and the demo on this page runs without an account.

How much does an AI teaching assistant cost?

Teacher-only assistants run about $100 per teacher per year at list price: MagicSchool Plus is $99.96 a year on annual billing. School and district plans are usually quoted. Coeducate publishes its price: Classroom is $89 a month or $528 a year for one teacher and 60 students, School is $349 a month or $2,088 a year for 10 educators and 600 students.

Will AI replace teaching assistants?

No, and a school should not buy it on that promise. A human paraprofessional reads a room, calms a student and notices who skipped breakfast. What AI takes off a human assistant is the guesswork: instead of arriving at a small group without knowing what each student is stuck on, the assistant gets a brief naming each student's misconception and the next question to ask.

What can an AI teaching assistant do for teachers?

A teacher-side assistant drafts lesson plans, differentiated texts, rubrics, quizzes and parent letters. A student-side assistant like Coeducate coaches students through practice with hints, names the misconception behind each wrong answer in the student's own words, groups the class by fault line for tomorrow and keeps a dated per-skill record you can bring to MTSS and IEP meetings.

Is an AI teaching assistant safe for student data?

It depends on the product and the agreement. Ask any vendor four things: will they sign your state's data privacy agreement, is student work used to train models, where is data stored, and how is it deleted. Coeducate never uses student work to train models, and our security and student data page answers the rest in writing.

Where the line between an assistant and a teacher sits, and why it matters for accountability, is set out in AI teacher vs AI teaching assistant. Math departments comparing tools can start with AI for math teachers.

09 For the person who signs off

Two things a curriculum director asks first

Evidence you can present

Per-skill mastery per student, exportable, with the student's own reasoning attached. It survives a board slide and an MTSS meeting because the wording came from the student, not from a summary.

A privacy posture built for minors

Student work is not used to train models. No advertising, no data resale, deletable on request. Designed around FERPA and COPPA obligations, and our security page states plainly which formal attestations we do and do not hold.

Rollout, procurement and the full sign-off checklist are on the pricing page, alongside the cost-per-student estimator.
