FREE
K-Map Solver
4-variable Karnaugh maps. Toggle cells, let the AI calculate groupings, and perfectly overlay geometry loops.
FREE
Truth Table Generator
Type any standard Boolean expression to instantly generate its full truth table, along with minterms and maxterms.
FREE
Binary Calculator
Perform base conversions (Binary, Hex, Octal, Decimal) and bitwise operations with step-by-step arithmetic explanations.
PRO
Schematic Analyzer
Upload circuit diagrams. Click components and ask AI to explain current flow, errors, and connections.
PRO
Interactive Breadboard
Upload your assignment schematics and let the AI physically guide your wiring on a 3D digital board.
PRO
Adders & Arithmetic
Half, Full, and 4-Bit Ripple Carry Adders. Live binary arithmetic visualization and decimal conversion.
PRO
Flip-Flops & Memory
Master sequential logic with SR, D, JK, and T flip-flops. Interactive clock pulsing and state history tables.
PRO
Quine-McCluskey
Full algorithmic reduction tables. Enter minterms and watch the solver identify essential prime implicants.
PRO
Boolean Simplifier
Algebraic simplification engine. Breaks down complex expressions step by step citing specific Boolean theorems.
PRO
Timing Diagrams
Enter a logic expression, set binary input signals over time, and let the tool auto-plot the output waveforms.
PRO
Counters & Timers
Build and simulate synchronous and asynchronous counters (up/down, modulo-N) with live timing visualizations.
PRO
MUX & DEMUX
Explore Multiplexers and Decoders with interactive select lines, live data routing paths, and Boolean equations.
PRO
Shift Registers
Visualize data shifting in real-time. Supports SISO, SIPO, PISO, and PIPO configurations with serial/parallel inputs.
PRO
IC Database
Searchable TTL/CMOS chip database (74xx series, 555, etc) featuring accurate internal logic gate visualizations.
ULTRA
Circuit Recreator BETA
Upload a circuit image and AI recreates it as an interactive SVG diagram. Click components to explore and ask follow-up questions.
ULTRA
Circuit to Code
Describe a digital circuit in plain English and the AI will generate functional Verilog or VHDL code for your hardware projects.
ULTRA
Exam Generator
Generate professional digital logic exams with answers and marking schemes. Perfect for practice and teaching.
01
Pick a Tool
Choose from a suite of specialized digital logic tools — each built to give you a clean, accurate workspace for the topic you're studying.
