Client Persona

Nexum remembers every client

  • Anonymised by construction — no raw identity
  • Curated by you, never auto-applied

Hi, what can I deduct as a freelancer this year?
Drafted by Nexum Hi Maria, a few common deductions for freelancers — your home-office share, business equipment, professional insurance and software subscriptions. Send me your receipts and I'll confirm which apply.

You review and edit before sending.

Privacy & control

Built to be safe, private, and yours to control

AI helps; you decide. Client data is anonymised before it reaches a provider, and nothing is ever sent on your behalf.

Anonymised by design

Client identifiers are stripped by a serialiser boundary before any context reaches an AI provider.

A human always decides

Every output is a suggestion. You review, edit and approve — Nexum never sends or files anything itself.

GDPR-compliant

We process client data under the GDPR — AI providers are named as sub-processors with EU-appropriate safeguards, and no tax advice is given.

FAQ

Questions about Nexum AI

Is it accurate?
Nexum is a capable assistant, but it can make mistakes — every output is a suggestion you review. It's grounded in your own notes and never invents facts on purpose. You remain the responsible professional.
Is my client data safe?
Client identifiers are anonymised by a serialiser boundary before any context reaches an AI provider. Free text you enter may still contain personal data, which is why a human always reviews. See our privacy policy for details.
Does Nexum give tax advice?
No. Nexum drafts and explains to save you time; the tax and legal judgement is yours. Its output is not advice from us and comes without warranty.
Which AI does it use?
Nexum runs on leading third-party AI providers, named as sub-processors in our privacy policy. We may switch providers to keep quality high; the model name never appears in the product.
What does it cost?
Start free — a monthly allowance of AI actions, no credit card. When you need more, upgrade to a paid plan; the AI credits scale with the plan.
