For implementation consultants & architects

Learn ServiceNow from the tables up.

LearnSN teaches the platform through its data model: 31 modules of animated, interactive diagrams of the real tables and relationships, with commentary that goes exactly as deep as you want. Then it makes you prove it — drills on the live graph, labs you build for real on your own dev instance, and timed mocks built to the published certification blueprints. And the same knowledge base ships as an MCP server, so what you learn in the app, your AI tools can cite on the job.

Invite-based and free. No account here — access is granted by email. Four real pages are readable right now, no invite needed.

How it teaches

Reading is the smallest part. LearnSN tests you four ways, each one a different kind of knowing.

Quizzes

Recognition

Knowledge checks with explanations close every module — do you recognise the right answer when it's in front of you? Progress persists, so weak spots resurface.

Drills

Diagnosis

Scenario problems posed on the live data-model graph — trace the relationship, pick the table, explain the behaviour. Results diagnose which exam domains are weak.

Labs

Doing

Every lab — task, hints, answer, and explanation — is fully readable in the app, and you build it for real on your own dev instance (a free PDI works). Run LearnSN locally against your instance and it grades you with read-only queries on what you actually built — no stored answer key to memorise.

Timed mocks

Rehearsal

Full-length papers built to ServiceNow's published certification blueprints — original questions, real weightings, exam clock. CSA, Data Foundations, CIS‑ITSM, CAD, and Architect.

What's inside

31modules, Foundations to Domain Separation

335lessons with layered commentary

238how-to guides with real scripts

39architecture decision write-ups

5certification exam banks

Every step of every build scenario is shown three ways — NOW UI clicks, server-side script, and REST API — and 293 tables are mapped with their relationships, from task and cmdb_ci down to sys_update_xml.

Counts are easy to print, so don't take them on trust: read a lesson, a decision guide, a table reference and a how-to — four real pages, generated from the same corpus, no account needed — before you ask for access.

One knowledge base, two clients

Everything LearnSN teaches is typed, structured content — the visual app is one way to read it. The other is ImplementSN, a remote MCP server that serves the same documented data model, scripts, and decision guides to your AI tools, so Claude answers ServiceNow questions from the actual documentation instead of model vibes — and audits, advises, and generates against it. All 38 tools, over plain HTTPS — no repo clone, no local install.

get_table · find_table_path

Table docs with field semantics and relationships — including the shortest relationship path between any two tables in the model.

build_checklist

Name a goal, get the matching build scenario as an ordered implementation plan — every step with its NOW UI clicks, server-side script, and REST call.

search_scripts

Curated, runnable GlideRecord / Cart API / aggregate patterns — the code you'd otherwise dig out of an old project at 5pm.

list_decisions

The "which option do I choose" architecture guides: a flat recommendation, the conditions that flip it, and the common mistake with its symptom.

exam_blueprint · practice_question

Certification prep in your chat: domain weightings with honest coverage, and original practice items drilled one question at a time.

export_diagram

Any slice of the data model as a Mermaid diagram — paste it straight into a PR description or design doc.
