Nexum AI

Meet Nexum — your AI co-pilot

Nexum is the AI built into TaxHILFE — it handles the repetitive parts of running a practice so your time goes to advice, not admin.

  • Catch up in seconds One click and Nexum summarises where any case stands and what's next — from your own notes and messages.
  • Draft replies First-draft client answers in their language and your tone. You review, edit and send — you stay the responsible professional.
  • Triage requests New requests sorted and summarised so you see fit and priority at a glance.
  • Remember every client An anonymised AI profile per client keeps every answer in context — no re-explaining.

Frequently Asked Questions for Professionals

What is Nexum AI and what does it do?
Nexum is the AI co-pilot built into TaxHILFE. It catches you up on any case in seconds, drafts client replies in your tone, triages incoming requests, and keeps an AI memory of every client — so the repetitive parts of running a practice take minutes instead of hours.
What are the costs and pricing plans?
Start completely free with our Free Plan – no upfront costs, no commission, and a monthly taste of Nexum AI. When you're ready for more clients and a larger AI allowance, upgrade to Starter (€79/month), Professional (€179/month), or Business (€399/month). Every plan includes Nexum AI and the full platform.
Is my clients' data safe with the AI?
Yes. Nexum works on anonymised data — identifying details are stripped before anything reaches the model — and our AI processing is GDPR-compliant with data kept in the EU. You decide what each client profile contains.
Do I stay in control of what the AI sends?
Always. Nexum only ever produces first drafts and suggestions — nothing is sent automatically. You review, edit and send, and you remain the responsible professional on every piece of advice.
How much Nexum AI is included?
Every plan includes Nexum AI. The Free plan gives you a monthly taste; Starter, Professional and Business each include a larger monthly allowance of AI actions, so heavier users get more without paying per use.
What can I automate?
Nexum can create tasks and reminders, track filing and appointment deadlines, draft routine client emails from the case context, and run repeatable workflows and tool connectors in the background — so admin happens without you chasing it.
How do I get verified and start?
During registration you provide your Steuerberater license number and certification details. We verify your credentials with the Chamber of Tax Advisors — usually within 2-3 business days — and notify you by email once you're approved. You can set up your profile and explore Nexum straight away.
Can I pause new clients or go on vacation?
Yes. Toggle your availability in your profile settings. When marked unavailable, your profile won't appear in new client searches, but existing clients can still reach you and Nexum keeps everything in order. Reactivate anytime without losing your profile or reviews.
