GT Graph vs Draftmind

GT Graph transforms your device into a powerful mathematical visualization tool. Plot equations, explore calculus concepts, and bring mathematics to life with stunning interactive graphs. PLOT ANY EQUATION - Cartesian functions - Polar curves - Parametric equations - Implicit equations - Inequalities with shaded regions INTUITIVE INPUT Type equations naturally with implicit multiplication support. Write 2x instead of 2*x, or 2sin(x) instead of 2*sin(x). GT Graph understands mathematical notation the way you write it. COMPREHENSIVE FUNCTION LIBRARY - Trigonometric: sin, cos, tan, sec, csc, cot - Inverse trigonometric: asin, acos, atan - Hyperbolic: sinh, cosh, tanh - Exponential and logarithmic: exp, ln, log, log2 - Power functions: sqrt, cbrt, abs - Constants: pi, e, phi (golden ratio) MULTIPLE GRID TYPES - Standard Cartesian grid - Trigonometric grid with pi-labeled axes - Polar coordinate grid with radial lines - Logarithmic scale grid CALCULUS TOOLS - Calculate derivatives at any point - Compute definite integrals with visual shading - Find zeros (roots) of functions - Locate local minima and maxima - Generate value tables INTERACTIVE EXPLORATION - Pinch to zoom, drag to pan - Tap to show tangent lines - Crosshair cursor displays coordinates - Plot multiple equations simultaneously - Color-coded graphs for easy identification SAVE AND SHARE - Save your work as .gtgraph files - Export and share with colleagues - Equation history saves your last 25 entries - Settings persist between sessions Perfect for: - Students learning algebra, trigonometry, and calculus - Teachers creating visual demonstrations - Engineers and scientists visualizing data - Anyone curious about mathematical beauty GT Graph combines the power of professional graphing software with the elegance of modern design.

Tired of reuploading a photo from your gallery every time you ask an AI for help? Draftmind is a sketchbook with a tutor built in. Use it for calculus, chemistry, physics, biology, coding interviews, history notes, languages or anything else you're working on. Sketch it out or talk it through. The page you're on goes with every question automatically. Keep working, keep asking. LEARN WITH AI, NOT AROUND IT • Do the work yourself and ask it to be checked step-by-step • See exactly where a solution went wrong, and why • Any subject: math, science, code, languages, diagrams and more • Tap the mic button and ask out loud, with your hands still on the pen, and hear the answer read back • Every chat is saved under what you first asked, drawings included. Pick it back up anytime, or save it as a PDF DRAW LIKE YOU WOULD ON PAPER • Pen, pencil and marker, each with its own feel • Shapes, text, fills and a full color wheel • Drop in a photo and write straight on it • Everything saves as you work FREE TO START Draw with every core tool and chat with AI for free. Draftmind connects to AI models through a free OpenRouter account you link: 50 messages a day with no card required, or 1,000 a day once you add $10 of credit. Nothing costs a cent unless you choose it. DRAFTMIND PRO • Offline mode: download an AI model and keep studying with no signal, with no account needed • Offline voices, and every natural voice • PDF import, PDF export and printing • Unlimited boards, folders, and backup to iCloud Drive or Google Drive • The highlighter and other advanced tools, and your own colors
