Introducing New capability - "Worked Examples"
Type a skill ("two-digit subtraction with regrouping", "Krebs cycle", "GRE ratios"). AI writes a fully solved step-by-step example with strategy + rationale + answer. Any subject, any grade. Download Solution PDF or Worksheet PDF. Share by link or email. Free, no signup.
I built this because every "AI homework help" tool I tried gave answers, not teaching. They show what the answer is. Teachers need to show how to think through it — that's a different artifact.
Worked Examples writes the artifact teachers actually use:
Strategy callout — names the approach in plain English ("isolate the variable, then back-substitute").
Numbered steps — each step has both what to do and why it works. The rationale is the part students miss when they only see an answer key.
Final answer + check-yourself prompt — built to catch the model's own arithmetic slips.
One click downloads either a Solution PDF (teacher reference / Google Classroom upload) or a Worksheet PDF (problems with blank lines for student work). Both client-side, both Letter-sized, both work for unsaved drafts too.
Save & share creates an anonymous /we/{slug} link with a hard 24-hour TTL — auto-deleted by Firestore, no signup, no account, no recovery. Need a permanent copy? Download the PDF before it expires.
Who benefits — concrete
Audience
What they get
Time saved
K-12 classroom teachers
A fully modeled "I do" example for any tricky skill, on demand. Project the Solution view, hand out the Worksheet PDF.
15-30 min of lesson prep per skill
Tutors (1:1 / 1:few)
Fresh examples per session — no re-using last student's printout. Different numbers, same skill.
5-10 min per session
Homeschool parents
Step-by-step explanations with rationale for skills they themselves last did 25 years ago.
The "I forgot how to do this" panic
Test-prep students (SAT/GRE/MCAT/AP/IB/JEE/NEET/etc.)
Targeted worked solutions for weak topics. Generate 5 examples → study → re-generate when you want fresh problems.
Vs. expensive prep-book solution manuals
College TAs / instructors
Discussion-section examples that match the lecture. PDF goes straight to Canvas.
Building example sets from scratch
ESL / Language teachers
Conjugation drills with rationale (preterite vs imperfect, ser vs estar) — explanations students can actually re-read.
Re-explaining the same rule 5 times
Co-teaching pairs / grade-level teams
Email a saved set to up to 5 co-teachers in one click — no Google Drive permission gymnastics.
The "can you share this?" Slack thread
Tech, since PH likes builders: React + Tailwind on Firebase Hosting, Spring Boot 3 + Firestore on Cloud Run, Vertex AI Gemini 2.5 Flash with structured-output validation + corrective retry. Per-IP rate limits keep classroom Wi-Fi fair.
No paywall planned. No "free tier" trick. If you teach, please tear it apart and tell me what's missing.
