What is the difference between Elta and Wolfram|Alpha?
Wolfram|Alpha is a computational knowledge engine: you ask a question and it computes an answer from curated data and exact math. Elta is an assistant that sees the screen, window, tab or image you share, talks it through by voice, and works with you on what is already in front of you.

What does Wolfram|Alpha do best?
Wolfram|Alpha is hard to beat for precise computation. It is strong at exact symbolic math, unit conversion, curated scientific and engineering reference data, and step-by-step solutions to well-posed problems. When you need an exact value from a clean question, it is an excellent tool and a great companion to Elta.
What does Elta do best?
Elta works with the work that already exists. You share a spreadsheet, report or page, and Elta talks it through where it sits, by voice, without you retyping the problem. It tells you its units and assumptions, asks when information is missing, and can take routine steps for you with your approval.
Should I use both?
Often, yes. Use Wolfram|Alpha to compute or look up a precise value, and Elta to work through the whole spreadsheet or report that uses it. The two answer different questions, and together they cover both the exact number and the work around it.

Frequently asked questions
Is Elta an alternative to Wolfram|Alpha?
For some tasks. Elta suits working through the work you already have; Wolfram|Alpha suits computing a precise value from a question.
Does Elta use curated reference data like Wolfram|Alpha?
Elta tells you the property data and assumptions it uses, so you can compare them with your own reference sources for the conditions in your work.
Can I use Elta for student homework instead of Wolfram|Alpha?
They do different things. Elta helps you understand and improve the work you did, and explains each step. Follow your instructor's policy on AI tools either way.
Do they work well together?
Yes. Many people look up an exact value in Wolfram|Alpha and bring it into the spreadsheet or report they are working through with Elta.
What can Elta see?
Only what you choose to share: a screen, a window, a tab or an image. You can stop sharing or end a session whenever you like.
Is Elta free to try?
Yes. The Free plan includes Elta and the Voice Agent with 100,000 tokens a day, and no credit card is needed. Upgrade to Plus or Pro whenever you want more room.
