Achieve more with 5 AI models that provide you with 1 defensible answer. Jarvis was built for medical examiners who write opinions that get scrutinized - starting with VA Compensation & Pension examiners drafting nexus opinions on tight deadlines. A single chatbot gives you one confident answer and sometimes a fabricated citation. Jarvis runs your question through five leading AI models in parallel - GPT, Claude, Gemini, Perplexity, and Grok - then synthesizes a consensus answer with a confidence score based on how strongly the models agree. Agreement is signal. Disagreement tells you exactly what to verify before it goes in your report. FOR THE HARDEST PART OF THE JOB • Research medical-literature support for service connection across decades • Check whether current findings are consistent with in-service events, exposures, and presumptive conditions • Pressure-test your rationale: if five independent models split on a question, so might a reviewer • Sources and citations surfaced for verification against the actual literature HOW IT WORKS • Ask once - five models answer independently, in parallel • Consensus synthesis with a confidence score on every answer • Swipe through each model's full response side by side • Every question saved as an experiment - revisit, share, export BUILT FOR ANY HIGH-STAKES OPINION IMEs, peer reviews, disability and workers' comp evaluations, utilization review - anywhere "the AI said so" isn't a defense. Jarvis is a research aid. It does not provide medical advice, and all clinical judgments and final opinions remain those of the examiner. Not affiliated with the VA, VES, or any government agency.
