About

neoloopy

Features
Read full description

neoloopy is a local-first tool for systems thinking. Map any system as a causal-loop diagram, let neoloopy find the feedback loops that drive it, grow a Graph: a system map that holds your ideas next to live references to your models, variables, loops, and concepts — and model a process as a Petri net and keep every run as evidence. PROCESSES — PETRI NETS (PRO) • Draw a process on the canvas: places hold tokens, transitions fire, arcs connect them. • Check a draft's health before you run it. Missing data, disconnected elements and undocumented meanings are listed; the draft tells you when it is executable. • Step the process and keep the run. Every run is immutable, pinned to the exact source revision it ran from, and replays the same way every time. • Document each element's meaning in Process Docs, right next to the drawing. • Export a process with its saved source, runs and analyses, and import it elsewhere with an explicit identity decision — create, replace or duplicate. • Part of Pro; included for everyone during the launch period. What you build stays free to open and replay. GRAPH — YOUR SYSTEM MAP • Put an idea on the canvas and link it to the real thing: a model, a variable, a loop, a concept from your vault. References stay live, so the map is never a stale drawing of your thinking. • Focus on one node and the map re-centers around it. A +N badge counts its hidden relations — tap to bring them in, tap again to prune. • Search the structure. The board lists every node and relation with search and filters, so a hundred-node map is still navigable on a phone. • Plain files. Every graph is a Markdown note in your vault, and graphs import from and export to Cypher for tools that speak property graphs. CAUSAL LOOPS, FOUND FOR YOU • Draw a variable, connect causes to effects, and mark each link same-direction (+) or opposite (āˆ’). neoloopy continuously detects every closed feedback loop and badges it Reinforcing (R) or Balancing (B) — the heart of how systems grow, stall, and stabilize. • Recognize the patterns. Classic archetypes like Limits to Growth and Tragedy of the Commons surface when your structure matches them. • Read the dynamics. Mark delays, flag virtuous vs. vicious cycles, and see how much of your model sits inside feedback loops. • See an edit's impact before you commit it: which loops it creates and which it breaks. • Annotate richly. Write a note on any loop or variable to capture what it means and why it matters. STOCKS AND FLOWS • When a map is ready for more, draw it in stock-and-flow notation on the same canvas — stocks as tanks, flows as channels — and export the result as SVG. ENGAGE — BUILD FROM YOUR INTENT • Tell Engage what you want a model to help you understand or decide. It asks one model-specific question at a time until the next useful increment is clear — not a generic checklist. • Guidance stays scoped to the model in front of you, so it asks about what your model actually depends on. • Pick a journey up where you left it, or end it and start another. LEARN AS YOU GO • A built-in systems-thinking glossary explains every term — causal link, polarity, delay, reinforcing, balancing — right where you need it. LOCAL-FIRST BY DESIGN • No account required. Download it and work offline. • Your models and graphs are plain Markdown files in a folder on your device — yours to keep, back up, and open in other tools. • Obsidian-compatible vault format. Your thinking is never locked in. • Search languages: English is always on; turn on Korean for a vault and its search index covers Korean text as well. • No ads, no tracking, no analytics inside the app. • Optional cross-device Sync (in development) is end-to-end encrypted: notes are encrypted on your device before they ever leave it, so we relay only ciphertext and cannot read your models. Map a business, a habit, a team, an ecosystem, a policy, a process — anything with moving parts that affect each other. Think in loops, and keep the map.
