ChatGPT for business vs Tessa: a chat for everything, or an assistant who works on her own
ChatGPT’s team and enterprise plans give you a general-purpose AI assistant for writing, analysis and almost any task. Tessa is more specific: she lives in your email, Slack and meetings and takes care of incoming work without being asked.
The chat answers brilliantly, but you have to ask
Plenty of companies have rolled out ChatGPT to their team and use it to draft, summarise, translate or think. It works, with one condition: someone has to open the chat, paste in the context and ask. What nobody asks for, it does not do.
Meanwhile, the day-to-day stays the same: emails waiting for a reply, meeting commitments nobody remembers, clients nobody chases. If you are looking for a ChatGPT alternative for your company, it is worth asking whether you need a smarter AI, or one that works on its own with what you already have.
How it works with Tessa
- 1
Connect your tools instead of pasting context
Each person connects Google and Slack in one click. Tessa already has the context: emails, messages, meetings and documents.
- 2
Review what Tessa has prepared
Prioritised tasks with a reply drafted in your tone, ready to send in one click.
- 3
Ask her like you would ask a colleague
“What was left open after the sales meeting, and who owns it?” Tessa answers from your data and cites her sources.
- 4
Delegate with routines
Write repetitive work down once: “every Monday, remind clients with overdue invoices”. Tessa does it and asks for approval for anything going out.
What you get
- Works without being askedShe reads what comes in and leaves the work ready. No chat to open, no emails to paste.
- With your company’s contextShe knows what you discussed with each client, what was agreed in each meeting and what tasks each person has.
- Does, not just answersCreates tasks, sends recaps, schedules meetings and drafts follow-ups, always with your approval for anything going out.
- Privacy per personWhat she reads for each person is theirs alone, and there are no individual metrics for managers.
- Built for European small businessesSpanish-first, with data stored in the EU, a tax calendar and, in beta, Holded and bank feeds.
What ChatGPT for business is
ChatGPT is OpenAI’s conversational AI assistant. Its plans for teams and enterprises add a shared workspace, admin and controls designed for organisations, along with the ability to connect some work tools and build custom assistants.
Its strength is versatility: it helps with writing, analysing documents and data, coding, brainstorming or learning, and people in every department use it.
Information about ChatGPT for business is based on its public website as of October 2026; it may change.
How Tessa is different
ChatGPT is a general-purpose tool you go to. Tessa is an assistant with a specific job that she does on her own: reading email, Slack, meetings and, in beta, WhatsApp Business; turning what matters into tasks; drafting replies; following up; and keeping the company’s memory.
So they do not compete on the same ground. ChatGPT wins on breadth: you can ask it almost anything. Tessa wins on the daily running of a small company: you do not have to ask her anything for incoming work to be sorted and ready.
- An inbox of tasks from email and Slack, with one-click replies.
- Meeting notes with tasks per owner (Meet; Zoom and Teams in beta).
- Automatic follow-ups and reminders of commitments.
- Sales without a CRM, a company wiki and a weekly pulse for leaders.
When to choose ChatGPT for business
If you want to give the whole team a versatile AI for writing, analysis, coding or thinking, ChatGPT is an excellent choice. It beats Tessa at open-ended tasks, data analysis and creative work that has nothing to do with email or meetings.
It also makes sense if your team already uses it daily and what you want is more AI capability, not automation of incoming work.
When to choose Tessa
Choose Tessa if your company’s problem is not thinking but keeping the thread: unanswered emails, ownerless meeting tasks, follow-ups that depend on memory. She fits small companies and startups on Google Workspace and Slack that want AI to do that work on its own, with approval for anything going out.
Many companies will use both: ChatGPT as a general-purpose tool and Tessa as the assistant who runs the day-to-day.
| ChatGPT for business | Tessa | |
|---|---|---|
| Main focus | General-purpose AI assistant | An assistant who runs the company’s daily work |
| Open-ended tasks, analysis and creativity | ✓ Its strength | Not her focus |
| Works without being asked | Not its focus | ✓ Reads what comes in and prepares the work |
| Tasks and replies from email and Slack | Not its focus | ✓ |
| Meeting notes with tasks per owner | Check its website | ✓ Meet; Zoom and Teams in beta |
| Approval for anything going out | Not applicable | ✓ |
| Data stored in the EU (Tessa) | Check its data policy | ✓ |
What Tessa reads for each person stays private, your data is stored in the EU and nothing goes out without your approval.
