A direct, honest comparison for professionals trying to decide between ChatGPT and a private on-device alternative. We'll tell you where ChatGPT wins (it does, sometimes) and where Hey Eduardo wins.
Every prompt you send to ChatGPT is transmitted to OpenAI's servers, processed there, and potentially logged. Those logs are vendor records that courts can reach: in 2025, a federal court in the New York Times lawsuit ordered OpenAI to preserve ChatGPT output logs for months, and logs kept under that order stayed available to the case after it ended.
In local mode, Hey Eduardo's model runs on your Mac and the data does not leave your computer, so there are no vendor records to subpoena and no preservation order that reaches them. The privacy question becomes one of architecture rather than contract.
For professionals handling client tax returns, financial plans, legal strategy, medical records, NDAs, or proprietary code, this difference is not technical — it's a different category of compliance posture.
Does Hey Eduardo send your documents anywhere? Let's watch.
Below the contract, Activity Monitor is tracking Hey Eduardo's network traffic.
Now ask a question about the liability clause.
It finds the three-month cap, and all three exceptions.
And Activity Monitor still shows zero bytes sent, and zero received. It all happened on this Mac.

For some workflows, ChatGPT is genuinely the better tool. Use the right tool for the right job — just don't use ChatGPT for confidential client work.
ChatGPT's 200K+ token context windows allow whole-book or whole-codebase analysis. Hey Eduardo works best on focused snippets. If you need to feed in 300 pages, ChatGPT is the right tool — assuming the content isn't confidential.
For the hardest problems — research-grade math, complex multi-step planning, advanced code refactoring across files — the very best cloud models still have an edge. The gap narrows every quarter, but it's real.
ChatGPT can browse the web and incorporate current information. Hey Eduardo's local model has a knowledge cutoff. For real-time research on non-confidential topics, ChatGPT is the right tool.
Use both. ChatGPT for non-confidential research, brainstorming, and the hardest reasoning problems where the prompt contains nothing identifying a client or proprietary work.
Use Hey Eduardo for everything else — anything involving a client's name, financial details, medical information, legal strategy, tax return data, source code under NDA, or any other information that could violate a professional obligation if it left your device.
The easiest rule of thumb: if you'd think twice before emailing it to a stranger, don't put it in ChatGPT.
For most everyday professional tasks — explaining documents, drafting communications, summarizing content, reasoning through problems — yes. ChatGPT's largest models have an edge on the hardest problems involving very long context. For most everyday professional work, the practical difference is small.
ChatGPT free uses your inputs for training and is subject to OpenAI's policies and preservation orders. If you handle any confidential material, ChatGPT free is not a defensible option — even if the price is right.
Enterprise has stronger contractual data protections and is a legitimate option for firms with the contracts and budget. But you're trusting a contract, not an architecture. With Hey Eduardo in local mode, there is no vendor receiving your data at all.
Most professionals will. Use ChatGPT for non-confidential work and Hey Eduardo for anything involving client material. That split is exactly what Hey Eduardo is built for, and its opt-in cloud mode can also connect to OpenAI with your own API key for work with no client data.
