Which AI tool is best for an EU public affairs team?
The honest answer is that it depends on you. Here is the map of what is on the market, six routes with their pros and cons, and a test you can run on your own work before you sign anything.
Sebastián Rodríguez Pérez is a European campaign strategist with direct experience running and advising campaigns for some of Europe's largest pro-European organisations. He founded the European Campaign Playbook to codify practitioner knowledge across the EU's 27 political environments and make it accessible to campaign professionals, advocacy teams, and civic organisations working at the European level. His work spans electoral strategy, EU public affairs, digital campaigning, and the integration of AI tools into political communication workflows.

What it covers
What the AI market actually looks like in 2026, six routes an EU public affairs team can take, what each one costs and where it stops, the two tools we leave out, and how to test a shortlist on your own work.
Who it is for
Public affairs, advocacy and association teams choosing an AI tool for themselves or for their organisation, and the people who have to sign it off.
When to use it
Before you buy, renew or standardise on an AI tool, and whenever somebody in your organisation asks which AI is best.
Key takeaway
Stop asking which AI is best, and ask what your organisation is short of: money, time, people or control. Each shortage points at a different route, and the layer you buy at matters far more than this month’s benchmark. Pick one route, run ten of your own tasks through it, and buy the smallest combination that fixes the real problem.
In brief
- Which AI is best? It depends, and mostly on what your organisation is short of: money, time, people or control.
- Know which layer you are buying at. A tool built for public affairs sits on top of a model, and answers a different question.
- If the supplier has to be European, start with Mistral. That is a fair requirement, and it sits alongside the question of whether the tool does your work.
- If everything already runs through Outlook and Teams, Microsoft 365 Copilot is the popular choice in Brussels, mostly because it is already there.
- If you want the newest tools and AI that carries out multi-step jobs, test ChatGPT and Claude on your own work.
- Running your own model trades convenience for control: you gain the control and take on the servers, the security and the testing.
- If monitoring and transcripts eat your week, Spaak, PoliVue and Prismos sell the part that is expensive to build. Check their coverage of your chambers.
- Rehearsal tools such as Retora are useful before a message meets real people. Treat the result as a rehearsal, and let real conversations settle it.
- Agentic tools come off the shelf with the agents already built and trained. Building your own, tuned to your files and your stakeholders, fits better once you have the time to do it.
- Two products stay off our shortlist: DeepSeek, over data stored in China and the findings of European regulators, and Grok, over the Digital Services Act proceedings into sexualised images of women and minors.
Framework
The four layers of the AI market
Where a product sits decides what you are paying for, and what it is really competing with. Last checked September 2026.
| Layer | Label | Description |
|---|---|---|
| Who builds the intelligence | Model providers | OpenAI, Anthropic, Google, Mistral, Meta. |
| The model that changes its name every month | Model families | GPT-5.6 and GPT-6, Claude 5.x, Gemini 3.8, Mistral Large 3, Medium 3.5 and Small 4, Muse Spark and Llama. |
| What your team opens every morning | Work platforms | ChatGPT and ChatGPT Work, Claude, Microsoft 365 Copilot, Gemini in Workspace, Mistral Vibe, Meta AI. |
| Advanced tools for public affairs, built for you | Specialist platforms | Spaak, PoliVue, Prismos, and message-testing tools such as Retora. |
Which AI is best? It depends on you
It is the question I am asked most often. Which AI tool should I use, and which one should my organisation buy?
My answer is always the same, and I know it is annoying. It depends.
The tools genuinely differ. It depends because every organisation is trying to fix something different.
A five-person association that lives in Outlook has a different problem from a consultancy that needs to know what was said in a committee last Tuesday. An organisation with ten engineers has options that an organisation with none does not. And if your board has already decided that the supplier has to be European, half the decision is made for you.
So the question to stop asking is:
Which AI is best?
And the question to start asking is:
What are we short of: money, time, people or control?
First, the map
Part of what makes this confusing is that people say “AI tool”, “AI model” and “AI platform” as though they meant the same thing. They do not. Four things are stacked on top of each other, and the layer you buy at decides what you are paying for.
In public affairs you choose in the bottom two layers: the tool your team opens every morning, and sometimes a specialist tool built for this job. The models underneath will change names every few weeks, and you will move with them without doing anything.
