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. As of May 2025, OpenAI is under a federal court preservation order to retain all output log data indefinitely. That means every chat, every uploaded document, every analysis you've done with ChatGPT since June 2025 is sitting in OpenAI's preservation systems.
Hey Eduardo's model runs on your Mac. The data does not leave your computer. There is no server to subpoena. There is no preservation order that applies. The architecture makes the privacy question structural rather than contractual.
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.
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-4 has an edge on the hardest problems involving very long context. For 90% of professional work, the practical difference is minimal.
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, 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. Many of our users have ChatGPT Plus AND Hey Eduardo for exactly this reason.
