The whole product, on one page.

• Portfolio auto-solveRuns every scheduling strategy, measures each, ships the strongest.
• Five goals, or let nOS pickFulfillment, section size, gender balance, seniority, or a hybrid.
• A real optimization pipelineGreedy pass, then Large Neighborhood Search, then ejection chains. Deterministic.
• Mathematical refinementMILPA mixed-integer optimizer works the requests heuristics could not place.
• Provable fulfillment ceilingThe mathematical maximum any scheduler could reach with your data.
• Pin and regeneratePinned sections keep their seats; everything else moves as little as possible.
• Backup course requestsAlternates fill in only when a first choice cannot be placed.
• Fair distribution of missesUnavoidable shortfalls spread rather than landing on the same students.

• 34 enforceable rule typesPeriods, singletons, teacher load, room type, pull-outs, adjacency and more.
• Plain-English rulesType “Keep AP Bio in period 3” and nOS compiles it into a constraint.
• Hard rules vs. soft preferencesA hard rule is a guarantee. A preference biases placement but never costs a seat.
• Contradiction detectionNames the smallest set of rules that actually conflict.
• Fails closednOS stops rather than shipping a schedule that breaks a rule you set.

• Spreadsheet importExcel, CSV and OpenDocument — nine formats, up to five files at once.
• Merge, never clobberA second import updates your data instead of replacing it.
• Import receiptsWhat came across, what could not be read, and how complete the coverage is.
• The Data CleanerDuplicate codes, retired courses, impossible teacher loads — fixed in place, with undo.
• No invented dataIf a request is missing, nOS says so rather than filling the gap.

• Independent verificationEvery invariant re-derived from scratch; a failing run does not ship.
• Twelve “why it missed” reasonsA plain-English obstacle on every unfilled request, not a status code.
• Grouped by causeSorted by the lever you would pull, so the work is already prioritized.
• Results workspaceSummary, student schedules, sections and Why Missed.
• Per-student explanationsDrill into one student and see exactly why their schedule looks that way.

• The BoardSections on a resource × period grid. Drag one and see validity before you let go.
• Schedule StudioSeven focused workspaces for what the solver left behind.
• ImproveRanked next moves, each showing its exact impact before you take it.
• Staged changesEvery edit lands on a pending layer with before, after and the resulting numbers.
• Rule-aware guardsHand edits are checked against the same rules the solver honored.
• Section plannerHow many sections of this do I actually need?
• Live staffing checkStaffing gaps flagged before you generate, not after.

• Scenario setsCompare runs on fulfillment, balance and conflicts, then promote the winner.
• Compare two schedulesAn explanation of what actually differs between any two.

• The in-app co-pilotIncludedAsk it to fill seats or resolve double-bookings; it stages the change and waits.
• Fast and Thinking modesQuick answers, or deeper reasoning when the question deserves it.
• Grounded, with refusalsAnswers from your actual data, and declines rather than guessing.
• Reads and writes notesAdds or resolves notes for you, on a confirmation card first.
• nOS AI AssistantSeparate appA standalone, read-only app that answers questions and changes nothing. More.

• Sticky notes and bookmarksRight-click anywhere; the note pins where you clicked and your school sees it.
• Live cursors and followSee who else is in, and mirror a colleague's screen in one click.
• Resolve or deleteAnyone can tick a note done; deleting is the author's or an admin's call.
• One shared librarySchedules, notes, workbook and pending changes belong to the school.
• Safe simultaneous editingThe newer save wins visibly instead of being clobbered by a stale tab.
• ActivityWho did what, with a name and a timestamp.
• RolesMembers schedule; administrators also own the SIS connection and billing.
• No per-user pricingAny number of staff. Pricing counts students, never logins.

How working together actually works

• Seven datasets, three formatsSchedules, sections, rosters, teachers, rooms and unfulfilled requests — CSV, Excel or PDF.
• Calendar filesA student's or teacher's schedule as .ics, or copied as plain text.
• Exports work on the demoSee exactly what comes out before you add a real student.

• 19 connectorsEleven on a shared OneRoster 1.1 connector. See the list.
