You already know how to give great feedback. The challenge is doing it well — for every student, every time.
Most feedback sounds good. Very little of it actually helps students improve.
If you teach writing, you're constantly choosing between thorough feedback, timely feedback, and your own wellbeing. You can usually manage two. Rarely all three.
Most tools help you write feedback. TA39 helps students use it — without you losing control of the rubric, the tone, or the final word.
Understand the promise. Decide whether this is worth your attention.
Thorough feedback, timely feedback, or your own wellbeing — pick two. Most tools try to solve this by making feedback faster. TA39 solves it by making feedback more useful.
Not a tool that grades for you. Not a replacement for your judgment. You define the rubric, set the tone, review every comment.

That's the concept. Here's what it actually looks like, on one real assignment, start to finish.

The impossible trilemma
Every writing teacher knows this tradeoff. It's not a personal failure. It's a structural problem.
Thorough but rare
You give detailed, thoughtful feedback — the kind that actually helps. But it takes so long that students get it back after the moment has passed.
Frequent but generic
You give feedback quickly so it's still fresh. But to keep pace, your comments become "Good job" and "Needs more detail." You know it's not enough.
Both — and burned out
You try to do both. Your feedback quality starts to depend on time, energy, and how many papers are still left. Something gives. Usually it's the sustainability of the process.
TA39 lets you do all three — without lowering your standards
Not by replacing your judgment. By handling the parts AI can do well — so you can focus on what requires your expertise, your knowledge of your students, and your professional voice. You decide when to use it. You decide what to keep. You decide what to change. Always.
This isn't a tool that grades for you.
"We're not going to show you a magic button that writes your feedback for you."
You already know what strong writing looks like. You've built the rubrics. You've refined your comments over years.
The challenge isn't knowing what to say. It's doing it consistently, at scale.
You didn't become a teacher to write comments students never use. TA39 is an assistant that works with you — you define the rubric, you set the tone, you review every comment before a student sees it. And you add what only you can know: that this student has been struggling at home, that this one needs a push, that this draft represents a real breakthrough.
How it actually works
Five steps. You're in control of every one.
Start with what you have
Upload your existing rubric. Optimize with AI acts as a rubric coach — it suggests where criteria could be sharper. You decide what to keep.
Build your feedback template
Set the tone, structure, and priorities of your feedback. Like giving instructions to a colleague who's helping you grade.
Students submit
Through Google Classroom, Canvas, or the standalone app. Students work where they already work.
Review and transform
TA39 generates a draft. You add the context, student knowledge, and judgment only you have. You decide what ships.
Track whether it lands
With Revision Rounds, see if students understood your feedback and applied it — criterion by criterion, draft by draft.
What actually changes
Before TA39
Feedback is detailed — but infrequent. Students get comments weeks after they've moved on.
Or feedback is frequent — but generic. "Good effort" across 30 papers.
Or you push through both — and you're grading at midnight, quality dropping with every paper.
Students receive feedback. Whether they act on it is anyone's guess.
With TA39
Every student gets specific, actionable feedback tied to your rubric — while it still matters.
Feedback stays consistent across classes and sections. Your standards don't drift with fatigue.
You get your time back without lowering quality. Pilots show 30-50% time savings in the first month.
Students don't just receive feedback — they revise with it. And you can see whether they did.
What makes TA39 different
Most AI tools focus on speed. TA39 is built around a different question: what does better feedback actually look like?
Teacher agency is non-negotiable
You review every comment. You adjust tone and specificity. You decide what students see. AI assists your judgment — it never replaces it.
"You stay in control. Always."
Feedback students can act on
Not more comments. Not longer explanations. Feedback that tells a student exactly what to do next. Specific, actionable, tied to your rubric criteria — the kind that drives revision, not just a grade.
"If a student reads it, they should know exactly what to do next."
Built for your curriculum
What counts as good feedback in IB is different from AP, which is different from CBSE or IGCSE. TA39 adapts to criterion-referenced language, marking scheme alignment, and command words — while staying flexible to your approach.
"TA39 adapts to your curriculum. Not the other way around."
Professional development, not just a login
TA39 includes a three-phase PD program that builds AI feedback literacy — the capacity to critically evaluate AI feedback, strategically adapt it, and maintain your professional voice. Not training on a tool. Growth as a teacher.
"Efficiency by itself is empty. Efficiency serving what?"
Built for teachers. Designed for schools.
TA39 isn't a tool teachers adopt alone. It's a system schools can implement — with professional development, curriculum alignment, and institutional support built in.
A real learning path, not a training video
A structured self-serve learning path helps teachers move from first use to confident practice. Product walkthroughs, best-practices guides, and guided reflection are organized so teachers build judgment — not just familiarity with the tool.
Curriculum-sensitive from day one
Works with IB, AP, CBSE, IGCSE, and more. Rubric optimization understands curriculum-specific language. Your assessment coordinator doesn't need to worry about standards alignment.
Secure, certified, ready for IT
1EdTech TrustEd Apps endorsed. LTI 1.3 certified. Data privacy certified. Google Classroom and Canvas integration. Full security documentation available before anything is installed.
You can keep working around the tradeoff. Or change it.
Keep doing what you're doing — and stay stuck in the tradeoff.
Use a generic AI tool — and lose control over quality.
Or build a system where your feedback works for every student, every time — and you still get to be the teacher.
