No credit card · all four major AI models in one place
Tax work is research, documentation and explanation wrapped around a filing. AI is fast at all three and dangerous at exactly one thing: it states last year's threshold with this year's confidence.
So the workflow is not 'ask and trust'. One model drafts the position, another argues against it, and a separate pass checks every number and citation against something current.
The rationale, at a length the client will read, ready for the file.

Claude for written positions, ChatGPT for computation logic, Perplexity when a figure needs a citation
Claude writes a defensible, readable memo. ChatGPT is stronger on worked calculations and scenario tables. Perplexity is the one you want when a threshold has to come with a source. Running them together is what turns a plausible answer into a checkable one.
Use it inside MultipleChatIt will, often. Thresholds, phase-outs and deadlines move every year and a model's training does not. Everything with a number in it goes through the fact check, and anything unsupported is flagged rather than passed on.
On paid plans nothing you enter trains a model and the providers do not retain it. Use initials and figures; the analysis does not need the name.
No, and the page is not pretending otherwise. It drafts, it argues the other side, and it tells you which claims it could not support. You sign the return.

Describe the situation with figures but without identifying details.
Read the Disagreements list — a split between models usually marks a genuinely arguable position.
Verify every threshold, rate and deadline against a current source before filing.
No. It helps you research, explain, document and pressure-test. Preparation and filing stay in your software and with you.
Assume not. That is the single most important habit with AI in tax work — treat every figure as unverified until the check attaches a source.
Yes. Upload it and ask what changed, what looks inconsistent, and what you would want to ask the client about.
It is excellent at it. Explaining the same position at three different levels of detail takes seconds and saves a long call.
