Notion AI vs Tessa: a workspace you maintain, or a memory that writes itself
Notion AI adds AI to the Notion workspace: writing, summarising and asking questions about your pages. Tessa builds your company memory from meetings, channels and documents, and runs email, tasks and follow-ups as well.
The wiki is well organised, but nobody updates it
Almost every company has tried to keep a wiki: processes, decisions, “how we do things here”. The problem is rarely the tool; it is the upkeep. Decisions are made in a meeting or a Slack thread and nobody writes them up. Three months later, the wiki no longer reflects how you work.
If you are looking for a Notion AI alternative, maybe what you want is not better writing inside Notion, but company knowledge that captures itself, plus someone who handles the daily work that comes out of those conversations.
How it works with Tessa
- 1
Connect Google and Slack
Each person connects their Google account and Slack. Tessa starts reading the meetings, channels and documents each person can see.
- 2
Let the memory build up
Decisions, processes and “how we do things here” are extracted from meetings and channels with their sources, respecting who can see what.
- 3
Ask as you would ask a colleague
“What did we agree with Kirai?” or “how do we onboard a client?”. Tessa answers and cites where she got it from.
- 4
Keep Notion if it works for you
If you use Notion for documentation or projects, carry on. Tessa’s Notion connection is in beta.
What you get
- A wiki that writes itselfIt does not rely on someone remembering to document: Tessa captures decisions from meetings and channels, with sources.
- Search everything at onceEmail, Slack, minutes, documents, tasks and contacts in one search box, with answers that cite their sources.
- Respects who can see whatWhat comes from your email is yours alone; what comes from a private channel is only for its members.
- Onboarding for new hiresWho is who, key clients and processes: every new person starts with a plan and someone to ask.
- And the day-to-day workBeyond remembering, Tessa creates tasks from email and Slack, drafts replies and follows up.
What Notion AI is
Notion is a workspace where teams write documents, wikis and databases and manage projects. Notion AI is the AI built into that workspace: it helps you draft, summarise and reorganise content, and lets you ask questions about what is in your Notion workspace and, depending on your plan, other connected tools.
Its strength is Notion’s flexibility: you can build almost any documentation structure and the AI works on top of it.
Information about Notion AI is based on its public website as of October 2026; it may change.
How Tessa is different
Notion AI works on what your team writes in Notion. Tessa works on what your team does: meetings, Slack messages, emails and Drive documents. The company memory is not written by hand; it is extracted from those conversations, with sources.
Tessa is also not just a wiki. She is an assistant for the whole company who turns what comes in into tasks, drafts replies, takes meeting notes and follows up. The memory is one part, not the whole product.
- Decisions and processes extracted from meetings and channels, with sources.
- One search box, with answers that cite where they come from.
- An inbox of tasks, one-click replies and follow-ups.
- Data stored in the EU, with permissions that respect who can see what.
When to choose Notion AI
If your team already lives in Notion, documents with discipline and wants AI to help write and find things inside that workspace, Notion AI is the natural choice. Also if you need a flexible editor to build your own databases, templates and project tracking, which is not what Tessa does.
For teams who enjoy designing their own system of work, Notion offers a freedom that an assistant like Tessa does not try to give.
When to choose Tessa
Choose Tessa if your documentation is never up to date because nobody has time to write it, and if the day-to-day also slips between email, Slack and meetings. She fits small companies and startups on Google Workspace and Slack that want an assistant who captures and acts, not just one who helps you write.
Plenty of companies can combine both: Notion for the documentation you want to curate by hand, Tessa for everything that gets decided without anyone writing it down.
| Notion AI | Tessa | |
|---|---|---|
| Main focus | AI inside the Notion workspace | AI assistant for the whole company |
| Wiki and documentation | ✓ You write it in Notion | ✓ Writes itself from meetings and channels |
| Flexible editor and databases | ✓ Its strength | Not her focus |
| Tasks from email and Slack | Not its focus | ✓ |
| Meeting notes | Check its website | ✓ Meet; Zoom and Teams in beta |
| Spanish-first | Check languages on its website | ✓ |
| 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.
Frequently asked questions
Is there a Notion AI alternative for a company wiki?
Yes. Tessa builds your company memory from meetings, Slack channels and documents, with sources. The difference from Notion AI is that you do not have to write it: it grows from what the team does.
Does Tessa connect to Notion?
Yes, in beta. Notion is one of Tessa’s task integrations, but it has not been tested with real accounts as much as Google Workspace and Slack.
Can everyone see Tessa’s wiki?
No. It respects who can see what: what comes from your email is yours alone, and what comes from a private channel is only visible to its members.
Does Tessa replace Notion?
Not necessarily. If you use Notion as your editor and project tool, Tessa does not replace it. She captures what gets decided outside Notion and runs the daily work.
Can I try it for free?
Yes. The company wiki is part of the Team and Business plans, with a 14-day trial and no card. There is also a Free plan for up to 3 people.
