What is Coachingle and how does it work?

Coachingle is a free AI-powered study platform that generates complete revision packs — cheatsheets, MCQs, mind maps, flashcards, audio podcasts, comics, slide decks, and animated videos — from any topic in under 30 seconds. Type a topic like "Photosynthesis" or "Rotational Motion" and the AI generates 8 different study formats tuned to your exam pattern (JEE, NEET, UPSC, Banking, SSC, or CBSE boards).

Is Coachingle really free?

Yes. Every student gets 3 free AI-generated study packs per day with no signup required. That covers daily revision for most aspirants. Paid plans start at ₹149 for a monthly subscription and ₹499 for a 6-month exam pack. There is no advertising, no data selling, and no paywall on core features like cheatsheets and quizzes.

Which exams does Coachingle support?

Coachingle has dedicated subdomains for 6 Indian exam verticals plus a global vertical: JEE Main + Advanced (jee.coachingle.com), NEET UG (neet.coachingle.com), UPSC Civil Services (upsc.coachingle.com), Banking exams including IBPS PO, SBI PO, Clerk, and RBI Grade B (banking.coachingle.com), SSC CGL + CHSL + MTS (ssc.coachingle.com), and study.coachingle.com for US/UK students preparing for AP, SAT, GCSE, A-Level, and GRE. Each vertical has exam-pattern specific features like sectional mocks, PYQ banks, and syllabus pages.

How is Coachingle different from ChatGPT or generic AI tools?

ChatGPT gives you text answers. Coachingle generates 8 different study formats from a single topic input — each one tuned to the specific exam pattern. For example, a JEE Main question follows the NTA pattern with -1 negative marking, while a NEET Biology question references the exact NCERT line number. The AI also tracks your weak chapters across sessions and adapts future content to your gaps. Coachingle is built for exam preparation specifically, not general knowledge.

Is Coachingle content NCERT-aligned?

Yes, for Indian exam verticals. NEET Biology questions link directly to specific NCERT chapter and line numbers. JEE syllabus follows NCERT Class 11 + 12. UPSC content cross-references official syllabus topics. CBSE board exam content is NCERT-first. For international exams on study.coachingle.com, content aligns with College Board (AP, SAT), Pearson/AQA/OCR (GCSE, A-Level), and ETS (GRE) syllabi.

Can coaching institutes use Coachingle for their students?

Yes. Coachingle offers an Institute Portal with two pricing tiers. Per-Student at ₹75/student/month includes core AI tools, basic analytics, and AI doubt solving — suitable for institutes with 50-5000 students. Institute Pro at ₹25,000/month base (plus ₹40/extra student beyond 500) includes full white-label branding, unlimited mock interviews, a private knowledge base for the institute’s own notes, automated parent reports, and batch management.

What AI models does Coachingle use?

Coachingle uses a multi-model architecture. Gemini 2.0 Flash handles most text generation (cheatsheets, audio scripts, conversational tutoring). OpenAI GPT-4 handles complex reasoning and Socratic dialogue for Snap & Learn. Gemini 2.5 Flash TTS generates two-voice podcast audio. Gemini image generation produces educational comics. Each format uses the best model for that specific job, not a single generic model.

Funkcja Kwadratowa Cheat Sheet

Key Definitions

Funkcja kwadratowa: Funkcja postaci f(x) = ax² + bx + c, gdzie a ≠ 0. ✅

Miejsce zerowe: Wartości x, dla których f(x) = 0. ✅

Wierzchołek: Punkt, w którym funkcja osiąga maksimum lub minimum. ✅

Oś symetrii: Linia pionowa przechodząca przez wierzchołek. ✅

Important Concepts

Właściwości funkcji kwadratowej

Parabola: Ukształtowanie funkcji kwadratowej.

Otwarcie: W górę (a > 0) lub w dół (a < 0).

Współrzędne wierzchołka: V(-b/(2a), f(-b/(2a))). ✅

Key Formulas

f(x) = ax² + bx + c

a: współczynnik kwadratowy (określa otwarcie paraboli) ✅

b: współczynnik liniowy ✅

c: wyraz wolny ✅

Miejsca zerowe: x = (-b ± √(b² - 4ac)) / (2a) ✅

Common Mistakes to Avoid

Common Mistake: Zapominanie o warunku a ≠ 0 przy definiowaniu funkcji kwadratowej.

Memory Tricks

Tip: "AXIS" —

A: a (współczynnik kwadratowy)

X: miejsca zerowe

I: wierzchołek

S: symetria
