Top 3 Picks
Microsoft 365 Copilot
Best AI for the whole organization
Microsoft 365 Copilot is embedded in every application your organization already uses — Word, Excel, PowerPoint, Outlook, Teams. It drafts documents, summarizes meetings, creates presentations, and analyzes spreadsheets without requiring any behavioral change. For businesses on Microsoft 365, it's the highest-ROI AI investment available.
- +Works inside every Microsoft app your team already uses
- +Zero change management — AI where work happens
- +Enterprise security, compliance, and data governance
- +Covers sales, finance, HR, ops, and comms
- −Microsoft 365 E3 or E5 license required
- −Performance varies across apps (better in Teams, variable in Excel)
- −Higher cost than standalone tools
ChatGPT Team (OpenAI)
Best for agile businesses and mixed stacks
For businesses not fully on Microsoft, or those that want AI without a platform commitment, ChatGPT Team is the most flexible choice. Every team member gets GPT-4o, DALL-E 3, data analysis, and custom GPTs — with admin controls and a guarantee that company data isn't used for training.
- +$30/user/mo covers almost every use case
- +Custom GPTs for company-specific workflows
- +Data not used for AI training
- +Works alongside any tech stack
- −No deep integration with specific business apps
- −Requires prompting — less automatic than Copilot
- −Less suitable for highly regulated industries
Make.com + AI
Best for business process automation
Make.com connects your AI tools (Claude, ChatGPT, Gemini) to the rest of your business — CRM, ERP, email, Slack, spreadsheets — automating repetitive workflows without custom development. For businesses looking to get more from their existing AI subscriptions, Make.com is the multiplier.
- +Connects 2,000+ business apps to AI models
- +No-code automation builder
- +Free tier for small businesses
- +Dramatically reduces manual, repetitive work
- −Requires setup time to configure workflows
- −Complex multi-step automations have a learning curve
- −Not an AI model itself
Frequently Asked Questions
What AI tools do most businesses use?
The most widely adopted business AI tools are Microsoft 365 Copilot (for Microsoft-centric organizations), ChatGPT Team (for flexibility), and Salesforce Einstein (for sales teams). Most businesses also use AI for customer support, marketing copy, and data analysis.
How do I start using AI in my business?
Start with one use case that has clear ROI: customer support chatbot, marketing copy generation, or meeting summarization. Measure the time saved, then expand. Don't try to AI-transform everything at once.
Is AI safe for business data?
Major enterprise AI platforms (Microsoft Copilot, ChatGPT Enterprise, Claude Enterprise) all offer strong data governance — your data isn't used for training. Always review DPA terms and ensure you have a signed data processing agreement before using AI with customer or confidential data.
What is the ROI of AI for businesses?
McKinsey estimates AI delivers 10–30% productivity improvement for knowledge workers. Our ROI Calculator suggests most businesses see payback within 1–3 months for AI tools costing $20–30/user/mo. The biggest gains come from automating repetitive tasks and accelerating content creation.
