ScenarioSplice is built by Colin Urban at Threadlimit.co. It grew out of StorySplice — an interactive fiction authoring tool — after we noticed that educators were using it to build something entirely different: decision-based training scenarios for their classrooms, clinics, and L&D programs. Public-health professors teaching outbreak response. Secondary teachers running digital-citizenship simulations. Clinical educators building triage cases. Customer-service trainers authoring de-escalation practice.
A branching scenario is a short interactive lesson where the learner is presented with a situation, makes a decision, and sees the consequences play out. Unlike a quiz — which tests recall — a scenario tests judgment. The learner reads the setup, weighs competing considerations, picks a path, and experiences what happens. Correct choices are reinforced. Mistakes become teachable moments. By the time a learner reaches the debrief, they've practiced the decision rather than just read about it. Research consistently shows that decision-practice learning transfers to real-world situations far more reliably than passive instruction.
Existing scenario-authoring tools fall into two camps. The first camp — Articulate, Captivate, and similar enterprise e-learning suites — are powerful but expensive, slow to learn, and built for corporate training departments, not individual educators. The second camp — Twine, Ink, and open-source interactive fiction tools — are free and flexible but require authoring in code-like syntax and have no opinionated workflow for educational content. ScenarioSplice is the middle ground: no code, no multi-thousand-dollar license, no blank-canvas intimidation. Every new scenario opens as a decision-tree skeleton you fill in. The editor is visual. The output is a link you paste into your LMS or email to your class.
Classroom teachers building case-study lessons. Instructional designers producing eLearning modules. Corporate trainers running soft-skills practice. Nurse educators creating clinical simulations. Public-health professionals teaching outbreak response. Anyone whose job involves teaching a decision — not just teaching facts.
StorySplice is our sibling product for fiction writers — novelists and game designers building branching narratives. ScenarioSplice shares the same underlying editor and publishing infrastructure, but the product surface is shaped around training: decision-tree templates by default, feedback tagging (correct / partial / incorrect), private facilitator notes per page, simpler "assign the link" publishing, and AI prompts tuned to educator voice rather than novelist voice. The two tools share accounts, so you can use both — but content created on one side stays there.
