Walnut vs Magnifi: Which Should You Use? (2026)
Last updated June 2026
Short answer
Magnifi and Walnut solve different problems. Magnifi is best for research and discovery in plain english; it generating stock ideas, scores, or signals to research. Walnut connects your own brokerage and lets you manage it by chatting through Claude or ChatGPT, with thematic baskets and trades you approve. Choose Magnifi if you want generating stock ideas, scores, or signals to research; choose Walnut if you want acting on the portfolio in your own broker and tracking it as thematic baskets.
Both get called “AI investing tools,” but they are not substitutes. Here is what each one actually does, whether it touches your real brokerage, what it costs, and when each is the better choice.
What Magnifi is

What Walnut is
