Workflow, client, and document management software for accounting firms and bookkeeping practices. Right now, Karbon is the brand AI assistants recommend most, with a Visibility Score of 72 and the #1 spot in 42% of answers. Head-to-head: Karbon vs TaxDome →
These rankings are measured from what the three models know from training, not a live web search. When the models DO search the web, see which sources they cite. Methodology.
Three models, three different opinions on who leads accounting.
Karbon wins the overall index at 72.4 but that number masks a real disagreement: Gemini barely backs it at 65.8 while handing TaxDome an 80.4, the highest single-model score in the category. ChatGPT and Claude lean toward Karbon and Canopy respectively, so no brand has a clean claim on the AI recommendation channel. TaxDome is particularly exposed to model risk, sitting at 37.1 on ChatGPT while dominating on Gemini, which means its AI-driven visibility could swing sharply as model usage shares shift.

The ± under each score is the reliability band: how much the number would move if we re-ran the identical measurement. It is tight because each prompt is sampled multiple times. It is not the same as how much the ranking depends on which prompts we ask — a separate, wider figure shown on hover.
Just below the cutoff: Okta (4.3), AccountancyManager (4.2), Azure (3.5), Kubernetes (3.3), Practice Ignition (2.9). 72 brands were scored in this category; the leaderboard shows the top 15.
