Three models. One answer.
Run Claude, GPT, and Gemini on every question in parallel — cross-examine their reasoning, verify divergent claims, and get one definitive response.
No credit card required
A single model can confidently hallucinate a citation, miss a critical angle, or lead you down entirely the wrong path. Moa runs three frontier models independently, then an aggregator cross-examines their answers and verifies the claims they make. Not three answers. One answer that earned its confidence.
Use cases
Each color represents a different model. Where they overlap, they agree. The final answer shows you exactly who contributed what.
The income is taxable in the US as self-employment income, subject to both federal income tax and self-employment tax. Germany generally does not withhold tax on service payments to non-residents under the US-Germany tax treaty (Article 7), provided you have no permanent establishment in Germany.
Report this on Schedule C, pay quarterly estimated taxes, and structure your filings correctly from day one — the US-Germany treaty protects you, but only if you proactively document and claim it. File Form 1116 to claim foreign tax credits and ensure treaty benefits appear on your return to prevent any double taxation.
Practically speaking, confirm with the German client that they are not withholding Quellensteuer on your invoice, and set aside 35-40% of the gross for US federal and state obligations. If they did withhold, you can recover it through the foreign tax credit mechanism.
One detail often missed: if the German client is VAT-registered, this transaction falls under the EU reverse-charge mechanism, meaning VAT liability shifts to them entirely and you do not need to register for German VAT. Ensure your invoice explicitly states "Reverse charge: VAT liability transfers to the recipient" to keep their books clean and avoid payment delays.
How it works
Three models. Three independent answers. One synthesis.
Your question goes to Claude, GPT, and Gemini simultaneously. Different training, different reasoning styles, different knowledge — three independent perspectives from a single prompt.
A synthesis model evaluates all three responses on merit alone — identifying consensus, surfacing contradictions, and flagging claims that need verification.
The strongest reasoning is combined into a single response. Divergent claims are verified. You see exactly which models contributed what — and where they disagreed.

FAQ
We manage this internally, always selecting the model best suited for synthesis. The synthesizer is one of the same frontier models available in your plan tier — Pro subscribers get a Pro-tier synthesizer, Max subscribers get a Max-tier one. We continuously evaluate which model produces the most accurate, well-structured synthesis and update accordingly, so you always get the best result without having to think about it.
For most people, Pro is all you need — and may even be the better choice. The Pro models are fast, extremely capable, and well suited for research, fact-checking, and everyday analysis. Max is designed for tasks that genuinely require deep reasoning and extended thinking: complex logic problems, multi-step analysis, or high-stakes decisions where you want maximum depth. If you're unsure, start with Pro.
You could — but then you're the synthesizer. You'd need to read three full responses, mentally compare them, spot contradictions, and decide which reasoning to trust. Moa does this automatically with a dedicated aggregation step backed by peer-reviewed research on multi-model synthesis. The result is faster, more consistent, and catches things you'd likely miss when scanning three responses side by side.
All three models run in parallel, so the first phase takes about as long as a single model response. The synthesis pass adds a few extra seconds on top — it's a lightweight aggregation step, not a full research pass. Total response time is roughly comparable to a normal chat response, plus a short wait for the synthesizer to do its work.
Yes. We do not sell your data or use your conversations for advertising, and no conversation data is used for model training — by us or by the AI providers we use. We do store conversations and limited usage and synthesis metadata so we can run, secure, and improve Moa, including giving you history and understanding how the models agreed or differed. You can request full deletion of your account and data at any time. For full details, see our Privacy Policy.
That's when Moa is most valuable. The synthesizer evaluates each position on the strength of its reasoning, not on majority vote alone. If two models agree but the third found something they missed, the stronger argument wins. For factual disputes, the synthesizer can run additional fact-checks via web search. The Venn diagram and color-coded attribution show you exactly where agreement and divergence occurred — and importantly, the models are given anonymous, randomized labels during synthesis, so there's zero bias toward any particular provider.
