People ask which AI is "best" for shopping Texas electricity. The honest answer: it depends on the task — and they all share the same blind spot. Here's how they stack up, and the one rule that applies no matter which you use.
| AI | Strongest for | Watch out for |
|---|---|---|
| ChatGPT | Reasoning over an EFL or bill you paste in; clear explanations | No live TX rates from memory; verify numbers |
| Claude | Careful, long-document reading of a dense EFL | Same live-data blind spot |
| Perplexity | Current background with cited sources | Citations can be marketing pages or stale rates |
| Gemini | Web-connected context; Google ecosystem | Not authoritative on your ZIP\'s filed rates |
The pattern is clear: the reasoning models (ChatGPT, Claude) shine when you give them the real EFL; the web-connected ones (Perplexity, Gemini) help with background. None of them has the live, ZIP-specific filed rates that decide your cheapest plan — that's what a real-data source is for. So the rule that beats every "which AI" debate: give whichever AI you use the real data, and verify against the EFL.

Common Questions
Which AI is best for shopping for electricity in Texas?
There is no single winner — it depends on the task. For reasoning over an Electricity Facts Label or bill you paste in, ChatGPT and Claude are excellent. For pulling current background with sources, a web-connected assistant like Perplexity or Gemini helps. But none of them reliably knows your ZIP's live filed rates, so whichever you pick, ground it with the real document and verify against the EFL.
Can Perplexity or Gemini get me current Texas rates because they browse the web?
They can surface more recent context than a model working purely from training data, and they cite sources — useful for background. But "browsing" is not the same as having the exact, current Electricity Facts Label for every plan in your ZIP. They can still land on an old marketing rate or a general range. Treat web-connected AI as better-informed, not authoritative, on live pricing.
Does it matter which AI I use to read my EFL?
Not much. Any capable model — ChatGPT, Claude, Gemini — will decode a pasted EFL well, because you have supplied the real numbers. Pick the one you already use. The quality of your answer depends far more on giving it the real document and your usage than on which brand of AI you chose.
