Microsoft 365 Copilot vs ServiceNow Otto (formerly Now Assist)

Quick decision: documents and meetings or service workflows?

Start with the employee's unfinished task, not the chatbot interface. Microsoft 365 Copilot is positioned around work-grounded help in Word, Excel, PowerPoint, Outlook and Teams. ServiceNow describes Otto as coordinating skills, agents and workflows where the organization keeps records, policies and approval chains. These aren't interchangeable subscriptions. Writing a document and resolving a service request can both involve AI, but they finish in different places and need different controls.

For a reviewed document, spreadsheet explanation or meeting recap in a Microsoft 365 organization, we would begin with Copilot. For an IT request, HR case or service workflow in a ServiceNow organization, we would begin with Otto. A firm can need both. This recommendation is about the job each platform documents, not a hands-on finding that one is faster or more accurate. We haven't run a comparative test, and a familiar interface isn't evidence of a better result.

Existing systems and license prerequisites

Check the exact plan, access path and approval boundary

Microsoft's enterprise pricing page lists $30 per user per month, paid yearly, for the add-on. A qualifying Microsoft 365 plan is a separate requirement, and Teams features need a Teams licence. Copilot Chat, available at no additional cost with eligible subscriptions, isn't the same entitlement as that paid add-on. Before multiplying $30 across the workforce, confirm the tenant, market and purchasing agreement. The seat figure alone doesn't tell you everything the organization needs to buy.

ServiceNow's public overview describes Foundation, Advanced and Prime tiers and directs customers to their account team for availability and entitlements. Rollout is independent of the instance upgrade cycle. Seeing the older Now Assist branding in documentation doesn't establish that your contract includes all current Otto capabilities. Put the required applications, plugins and skills against the written quote. We wouldn't budget for a capability on the strength of a product name alone.

Data access and governed actions

Test reading and writing separately. In Copilot, check source permissions and shared documents using the employee role that will do the work. In Otto, check the record, workflow and approval policy for the requested change. A plausible answer doesn't establish permission to update a record. Use safe sample data and ordinary employee accounts, not just an administrator who can see and change everything. The test needs to reflect the access your staff will actually have.

AI Control Tower appears across ServiceNow's tiers, but full management of external AI assets requires a separate Enterprise AI licence. The documentation also separates embedded Workflow Data Fabric Foundation from paid Advanced capabilities. Check those distinctions if the design crosses platforms. A connector or supported protocol doesn't prove that the contract covers it, that its permissions are safe or that your organization has approved the integration. Those are questions to settle before broadening the pilot.

Total cost: seats, usage and implementation

Put fixed charges and variable usage on separate budget lines. Microsoft's enterprise add-on doesn't include the base Microsoft 365 subscription; some agent scenarios can add consumption charges under separate terms. The ServiceNow pages used here don't publish a universal Otto seat price or assist allowance. Ask for the usage definition, quantities included, overage behavior and renewal terms. We don't fill those gaps with a guessed price just to produce a neat side-by-side total.

Implementation needs a budget too. Documents need owners and sensible sharing. Service workflows need clean records, useful knowledge and reliable handoffs. Record who will own the setup, integration work, review and support. Don't count the entire existing platform bill as new AI spending; do include extra requirements created by the pilot. We haven't prepared a customer-specific quote or measured a return on investment. Internal work is part of the decision even when it doesn't appear on a pricing card.

Coexistence and a two-week pilot

We suggest a two-week pilot with a limited job for each platform, not a race between unrelated tasks. A small Microsoft 365 group could evaluate recurring drafting or meeting work. A ServiceNow service team could evaluate one defined request with human approval. Record correctness, rejected output, escalation quality and administrative effort for each. Two weeks is a proposed evaluation period, not a claim that either implementation will be complete within that time.

Include cases that should fail: an inaccessible document, missing request details and an action that needs human approval. Check where the logs live, who investigates a failure and how to disable the workflow. Expand only when the task owner accepts the result. We would buy for the completed job under the organization's controls, not for the broadest marketing claim. If the jobs are different, using both may make more sense than declaring a winner.
