Questions & Answers

As answered by people managing Codewars and TeachTools.

What makes your product unique?

TeachTools's answer:

TeachTools is the only AI toolkit for teachers that puts student privacy first โ€” not as a feature, but as the foundation.

๐Ÿ”’ FERPA-compliant by design โ€” student data is encrypted end-to-end and never stored or sold

๐Ÿง  23+ AI-powered generators โ€” worksheets, quizzes, lesson plans, rubrics, crosswords, bingo cards, and more

๐Ÿ“ Easy Grader โ€” upload an answer key + up to 100 student papers and get every assignment graded in minutes with per-question breakdowns

๐ŸŽจ Custom headers & footers โ€” brand every document with your name, school info, and custom backgrounds so output looks like yours, not a robot's

โšก Try before you sign up โ€” every tool lets teachers fill out the form and preview results before creating an account

Most AI tools sell features. TeachTools sells permission to trust an AI tool in your classroom.

Why should a person choose your product over its competitors?

TeachTools's answer:

Every competitor asks teachers to make a trade: use our AI, but hand over your classroom data and hope we do the right thing. TeachTools doesn't ask.

  • Military-grade encryption on every document โ€” your students' information never leaves the vault
  • No data harvesting โ€” we don't store student data, don't sell it, don't "anonymize" it. It doesn't exist on our servers after generation.
  • 23+ tools in one place โ€” no juggling 5 different subscriptions for worksheets, quizzes, grading, and lesson plans
  • Easy Grader โ€” the only bulk grading tool that processes up to 100 handwritten or digital papers against your answer key, with OCR built in. No other teacher AI tool does this.
  • Zero AI fingerprint โ€” output uses plain keyboard characters only. No emdashes, curly quotes, or AI tells. Your principal will never know.
  • Educator pricing โ€” verified teachers get Pro for $9/mo, and it's tax-deductible as a classroom expense

Teachers don't need another AI toy. They need a tool they can actually use without a risk assessment from their district's IT department.

How would you describe the primary audience of your product?

TeachTools's answer:

K-12 teachers who are drowning in prep work and desperate for help โ€” but can't afford to compromise on student privacy.

That includes: - Classroom teachers across every subject and grade level

  • First-year teachers who need quality materials now, not after 10 years of building a resource library

  • Veteran teachers buried in grading who want their evenings back

  • Teachers in rural and underserved schools who deserve the same resources as well-funded districts

  • International educators in 15+ countries generating content in multiple languages

  • Instructional coaches and curriculum coordinators building materials at scale

If you've ever stayed up until midnight making a worksheet, TeachTools was built for you.

What's the story behind your product?

TeachTools's answer:

A first-year teacher in rural Oklahoma shouldn't have worse resources than a veteran at a Manhattan private school. But they do โ€” because great materials take time, and time is the one thing no teacher has enough of.

TeachTools exists to fix that.

We watched teachers spend their nights and weekends building worksheets, writing quizzes, and grading stacks of papers by hand โ€” burning out of a profession they chose because they love kids. Meanwhile, AI tools kept launching that treated student data like a commodity. "Just paste your roster in!" No thanks.

So we built the opposite: 23+ AI generators that create classroom-ready materials in seconds, protected by military-grade encryption, fully FERPA-compliant, with zero student data ever stored or sold.

The mission is simple: give every teacher the tools to spend their time where it matters โ€” with their students.

Which are the primary technologies used for building your product?

TeachTools's answer:

  • Backend: Node.js with Express.js
  • Database: PostgreSQL (Neon)
  • AI/LLM: OpenAI API (GPT models for content generation, Vision models for OCR-based grading)
  • Image Generation: DALL-E
  • Hosting: Render
  • Payments: Stripe (subscriptions, educator verification, tax-deductible receipts)
  • Analytics: PostHog
  • Media Storage: Cloudflare R2
  • Security: End-to-end encryption, FERPA-compliant architecture, session-based auth with Google OAuth

Who are some of the biggest customers of your product?

TeachTools's answer:

  • Individual K-12 classroom teachers across 15+ countries
  • Public school teachers in the United States navigating strict FERPA compliance requirements
  • Teachers in rural and Title I schools who lack access to premium curriculum resources
  • Private school educators looking for fast, professional-grade materials
  • International educators generating content in English, Spanish, and other languages
  • Instructional coaches building standardized materials across departments
  • Homeschool parents creating structured curriculum for their children

  • Of recursion and backtracking
    Recently, I was working on a coding kata on codewars.com. Early on, I started thinking that a potential solution might utilize recursion, a concept that involves a function calling itself. However, I quickly realized that my grasp of recursion was not as solid as it needed to be for this task. In this post, I will share the insights gained from deepening my understanding of recursion while working through the kata. - Source: dev.to / over 2 years ago
  • 4th year, about to fail an entire semester's worth of classes.
    Get more involved. Look into internships and junior SWE positions to get a sample of what you'd be applying for once you graduate. Solve coding challenges, start working on a portfolio of your personal works. I recommend codewars.com for coding challenges, it's fun. Source: over 2 years ago
  • Beginner with C++ looking for direction
    I'd recommend to play around with some basic coding challenges on leetcode.com or codewars.com. If the course prepared you well you won't find this useful, but playing around with them will make sure that you are comfortable with basics such as loops, if statements etc. Source: almost 3 years ago
  • Can you guys recommend an efficient way to learn in advance IT para sa mga walang alam?
    I would advise for you to start with Python, it's a beginner-friendly programming language and it'll help with wrapping your mind around things. Play around with it, perhaps do some katas on CodeWars and you'll be set. Source: about 3 years ago
  • How do I develop programming logic?
    There is a website called codewars.com where you can select problems of varying difficulty for the language you need. It is very helpful for learning. Source: about 3 years ago
