Will or ChatGPT? An AI that keeps operations moving, or an AI for everything.
ChatGPT is a general-purpose AI: it writes, analyzes, researches and codes, and on the Business plan it works with the team’s context. Will works for the whole company: it’s in the ERP, the bank, the store and WhatsApp and keeps operations moving, from the late order to the supplier who didn’t reply.

Will
Honest summary
For writing, analysis, research and coding, ChatGPT is a strong choice, and you can use both. When the work is chasing down operations, with orders, suppliers, the bank and customers, in the systems the company already uses, Will was built for exactly that.
| Criterion | Will | ChatGPT |
|---|---|---|
| Who it’s for | The whole company, or just one team | Individuals (Free, Go, Plus and Pro) and companies (Business, from 2 users, and Enterprise) |
| Company data | The ERP, banks through Open Finance, the store, the CRM, the marketplaces, email and WhatsApp | Shared company context and plugins, ready-made or built for the company’s systems |
| How it works | Finds what’s stuck on its own, makes a plan and chases it until it’s solved | With ChatGPT Work, it takes a goal, gathers the context, makes a plan and carries it out |
| Before acting | Acts on its own within what you’ve allowed and tells you after, with a receipt for every action | Calls you in when it needs your input or approval |
| Team controls | Each person sees only what they’re allowed to see | Admin controls for users, usage and billing, with SSO and multi-factor authentication |
| Your data | Details in Security and LGPD (Brazil’s data protection law) | On Business, data isn’t used to train the models |
