Problem Statement

Workplace AI fails when every employee gets another generic assistant. The stack should match the actual system of work, protect connected email and files, and reserve paid seats for roles with measurable repeat work.

Recommended Stack

Use Microsoft 365 Copilot if the company runs on Microsoft 365, Gemini if it runs on Google Workspace, NotebookLM for source-grounded research packets, and Superhuman only for roles where email throughput is a real bottleneck.

Stack Guidance

Must-have

  • Microsoft 365 Copilot or Gemini
  • NotebookLM

Nice-to-have

  • Superhuman only for approved high-volume inbox roles
  • ChatGPT
  • Notion AI

Avoid for now

  • Suite AI rollout before file, mailbox, and group permissions are cleaned up
  • Paid seats for casual users who only need occasional free-plan drafting
  • Skip premium mailbox AI for roles where email is not a measurable bottleneck
  • Mailbox AI connected to sensitive inboxes without security approval

Decision Tree

  1. Is Microsoft 365 the actual source of work?

    Evaluate Microsoft 365 Copilot after cleaning up SharePoint, OneDrive, Teams, and mailbox permissions.

  2. Is Google Workspace the actual source of work?

    Evaluate Gemini with Workspace admin review and rules for Drive, Gmail, Docs, Sheets, and Slides data.

  3. Is the team summarizing known documents more than searching the web?

    Use NotebookLM for approved source packs so conclusions stay traceable to source material.

  4. Is inbox response time the expensive bottleneck?

    Pilot Superhuman with high-email roles only after mailbox access and AI data use are approved; otherwise skip it as a default stack purchase.

Budget Tiers

  • Free: Use free assistants and NotebookLM on non-sensitive material to validate recurring tasks before connecting email, files, or calendars.
  • Solo: Pick the assistant that matches your personal workspace; add Superhuman only if inbox speed justifies the premium.
  • Small team: Pilot with one function, one suite, and clear rules for what can be pasted, summarized, or connected.
  • Enterprise: Require tenant permission cleanup, SSO, auditability, retention review, legal/security approval, and role-based seat assignment.
