Accounting & Tax AI
Karbon AI (Kai)
Medium riskAI assistant built into Karbon's practice management platform for accounting firms, summarizing and drafting across the firm's client emails, tasks, and work items.
Is Karbon AI (Kai) safe for confidential data?
Karbon AI's contractual posture is solid — the platform is SOC 2 Type 2 certified, Karbon states firm data is not used to train AI models or shared across customers, and its AI features are built on the Azure OpenAI Service, which does not use customer prompts to retrain models. What earns the medium rating is scope: Kai operates over the firm's entire client email history and workpapers, so a single practice-management login now fronts an AI layer across every client's correspondence, and Karbon has implemented but not independently certified ISO 27001. Karbon's own State of AI in Accounting 2026 report captures the industry mood precisely: 98% of accounting professionals now use AI, while 83% report data-security concerns — up seven points in a year.
Risk by plan
The same product often carries very different terms depending on the tier — consumer plans are where the exposure concentrates.
AI is a platform feature under the firm's subscription; there is no free consumer tier, so usage is inside the agreement by default.
Data handling
Training on inputs
Karbon states firm data is not used to train AI models and is not shared with third parties or used to inform other customers' experiences; the same policy applies across plans, since AI ships as part of the platform rather than as a separate consumer product.
Retention
Client emails and work items persist in Karbon as the firm's system of record under the subscription terms; Karbon does not publish AI-specific retention windows for Kai interactions. Backups are encrypted with AES-256.
Residency
Hosted on Microsoft Azure; Karbon's security page does not advertise customer-selectable data residency — firms with Canadian or EU residency requirements should confirm hosting regions before onboarding.
Compliance
- SOC 2Yes
- GDPR / DPAConditional
- HIPAA BAANot verified
Certifications typically apply to specific tiers and contracts — confirm scope in writing before relying on them.

Frequently asked questions
Is Karbon AI safe for client communications?
The vendor controls are reasonable: SOC 2 Type 2, encryption, a stated no-training policy, and Azure OpenAI underneath, which contractually excludes prompts from model training. The risk to manage is concentration — Kai reads across your entire client email history, so access control, offboarding, and MFA on Karbon accounts matter more than they did before AI, because one compromised login now exposes an AI-searchable archive of every client.
Does Karbon train AI on our firm's data?
Karbon states it does not: firm data is not used to train AI models, is not shared with third parties, and does not inform other customers' experiences. Note that its ISO 27001 implementation is self-attested rather than independently certified — SOC 2 Type 2 is the audited claim to rely on.
If our practice management tool has AI, is our AI risk handled?
No. Karbon's own 2026 State of AI in Accounting report found 98% of accounting professionals use AI while 83% hold data-security concerns, and much of that use happens in general-purpose chatbots outside any platform. A sanctioned, contracted AI inside Karbon does not stop staff pasting client details into free tools for the tasks Karbon does not cover — that unsanctioned layer needs its own policy and controls.
