What the models actually said.
The ranking is the answer; these are the words behind it. Every quote is from a recorded model answer — follow the category to read it whole.
Bitwarden
Bitwarden — The best overall value and my default recommendation for people who want open-source clients, strong zero-knowledge encryption, excellent free cross-device use, and the option to self-host without sacrificing mainstream usability.
ChatGPT
LastPass
LastPass – Explicitly NOT recommended by most current guides and AI models due to its 2022 breach (stolen encrypted vaults and unencrypted metadata) and the resulting erosion of trust; it's included here only because it's still widely used, not because it's endorsed.
Claude
Bitwarden
Bitwarden — best value and best transparency: choose it if you want a highly capable, open-source, zero-knowledge manager with a very strong record of public third-party assessments, optional self-hosting, and an unusually good free tier.
ChatGPT
LastPass
LastPass — Still widely known and feature-rich, but I would rank it below the leaders because buyer confidence has been damaged by past security incidents, making it a harder recommendation today.
Perplexity
Where the models split.
Across the 2 categories Bitwarden and LastPass both appear in, the models never break ranks: in each one, the same brand leads on ChatGPT, Claude, Gemini, and Perplexity alike.
No model runs against the grain here: each of the four ranks Bitwarden ahead at least as often as not, with Gemini the most lopsided.
The race is tightest in Password Managers (8 ranks apart) and widest in Top Password Managers 2026, where Bitwarden leads by 9.
