Singular vs anti/agent

Singular is a professional-grade analog & logic circuit simulator designed for your iPhone and iPad. Build, simulate, and analyze electronic circuits with an intuitive drag-and-drop editor and a powerful real-time simulation engine — no internet required. Whether you're an electrical engineering student studying for exams, a maker prototyping your next project, or a professional verifying a design, Singular gives you a complete electronics workbench in your pocket. POWERFUL SIMULATION ENGINE • Modified Nodal Analysis (MNA) with TR-BDF2 adaptive solver • Real-time transient, DC, and AC analysis • Frequency-aware adaptive timestep — accurate results at any speed • Newton-Raphson nonlinear convergence for semiconductors • Hot-swap: modify your circuit while simulation is running 40+ ELECTRONIC COMPONENTS Passive — Resistor, Capacitor, Inductor, Potentiometer Sources — DC Voltage, AC Voltage, Pulse Generator Diodes — Standard Diode, Ideal Diode, LED Transistors — NPN, PNP, Darlington PNP, N-MOSFET, P-MOSFET Integrated Circuits — NE555 Timer, Operational Amplifier (Op-Amp) Logic Gates — AND, OR, NAND, NOR, XOR, XNOR, Inverter, Buffer Flip-Flops — D, JK, T Flip-Flop, SR Latch Measurement — Voltmeter, Ammeter Power Rails — Ground, VCC, VDD, VSS, VEE, ±3.3V, ±5V REAL-TIME OSCILLOSCOPE • Multi-trace display with color-coded signals • Adjustable time base and voltage scale • Pinch-to-zoom and pan gestures • 60 fps rendering — smooth and responsive INTUITIVE CIRCUIT EDITOR • Drag-and-drop component placement with grid snapping • Draw wires by tapping terminals — automatic routing • Rotate, flip, and mirror components freely • Multi-select, move, and organize your design • Full undo/redo history (up to 100 steps) • Pinch zoom (0.1x–5x) and two-finger pan PROFESSIONAL TOOLS • Design Explorer with automatic reference designators (R1, C2, U3…) • Standard value picker — E12, E24, E96 resistor series and standard capacitor values • Built-in expression evaluator — type "10k*2.2" and get the result instantly • Real-time voltage, current, and power readouts on every component • Net name visualization for complex designs LEARN & EXPLORE • Built-in example circuits: Voltage Divider, Current Divider, Inverting Amplifier, 555 Timer Demo • Resource Center with reference articles • Detailed simulation error guide — understand what went wrong and why • Save examples to your workspace and modify them freely SAVE, EXPORT & SHARE • Save unlimited circuits to your workspace • Export circuits as portable .circuit files with embedded thumbnails • Import circuits from other users or devices • Add names, descriptions, and metadata to every project DESIGNED FOR iPAD & iPHONE • Built 100% with SwiftUI for a native Apple experience • Optimized for both touch and Apple Pencil • Works entirely offline — your data stays on your device Singular is the circuit simulator that students wish they had during lectures, that makers reach for at the workbench, and that engineers trust for quick verification.

Stop AI brain rot. Turn any PDF, video, podcast or question into ideas you practise a few minutes a day, and that come back right before you forget. AI answers everything, and you keep nothing. A week later you could not explain it to a friend, because the thinking happened somewhere else. An agent thinks for you; anti/agent makes you think. It never writes for you: the AI reads your sources and writes the questions, and the answers are yours. A few minutes a day, and what you read, watch and wonder about becomes ideas you understand, remember and can argue with. START FROM ANYTHING A PDF, a textbook chapter, slides, a photo of a page, a web page, a YouTube video, a podcast, or just a question. Say what you want from it. anti/agent finds the ideas, puts them in the order they build on each other, and gives each one a page. With only a question, it finds sources on the web and tells you why it kept each one. You see the plan before anything is built, and you can change it. A FEW MINUTES A DAY. YOU DO THE ANSWERING. Each session takes one subject and mixes what is new with what is about to slip. You guess before you are told, then answer in many forms: choose, fill the blank, put steps in order, match, write a formula, predict what code prints. A miss comes back once, easier, before the end. No streaks to protect: a session is as long as you set it. CULTIVATE YOUR CRITICAL THINKING Recognising an answer is not understanding it. Once you know an idea, anti/agent asks you to use it: explain it in your own words while it pushes on the weak spot, spot the flaw in a claim that sounds right, or solve a problem step by step, with one hint when you stall. It asks; you explain. GROUNDED IN YOUR SOURCES Every question, fact and correction comes from the material you brought, and every fact opens the passage it came from, with the page or the minute. When your sources do not settle a question, anti/agent says so and asks again tomorrow instead of guessing. IT COMES BACK RIGHT BEFORE YOU FORGET Spaced practice, scheduled for you. Every idea keeps its own memory: when you answer, the engine works out when you would be about to lose it, and brings it back just before. A SHELF OF THINGS YOU UNDERSTAND Each idea gets a page: one sentence, three facts, your notes, and a cover drawn from what it says. The cover starts as a line drawing and colours in as you learn it. Stop practising and the colour wears off; the drawing stays. Share any page as a public page, free to read. Never your progress, never your files. YOURS, IN YOUR LANGUAGE The app and everything it writes for you come in English, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Portuguese and Spanish. Your material stays private to your account. We do not sell your data and we do not use it to train AI models. Export everything, or delete your account, from Settings. On iPhone, iPad, Mac and the web, with one account. PLANS Practice is never limited. A plan sets how much new material you add: an add is one thing you bring, or one chapter you build; a page is a PDF page, a slide, a picture or 3,000 characters. • Free: 3 adds a month, up to 20 pages each. • 14-day trial for every new account, nothing to buy: 8 adds of up to 50 pages, YouTube and audio included. • Starter: 8 adds a month, up to 50 pages each. • Pro: 20 adds a month, up to 200 pages or 2 hours of video and audio each, YouTube and audio included. • Unlimited: no monthly count (fair use: 5 adds a day), up to 500 pages or 4 hours each, YouTube and audio included. Starter, Pro and Unlimited are optional auto-renewing monthly subscriptions; the app shows each price in your currency. Payment is charged to your Apple Account when you confirm. A subscription renews every month unless you turn it off at least 24 hours before the period ends. Manage or cancel it in your App Store account settings.
