Users report Claude's new file-based memory system generates unsolicited personality profiles

Multiple users on Reddit report that Claude's new file-based memory system, which replaced the classic memory feature, is generating unsolicited personality profiles and making inferences about users without explicit input. Users describe the system as a downgrade due to migration issues, lack of tool call visibility, and content filtering problems. One user noted that after resetting memories, the system created a new profile that appeared to be Claude's opinions rather than factual memory.

On July 13, 2026, several Reddit posts criticized Anthropic's new file-based memory system for Claude. One user with 25 active fiction projects described the migration as a significant downgrade, citing poor migration quality, lack of tool call visibility, and content filtering issues. Another user reported that after three months of never using Mandarin, Claude ended a session with the Mandarin word '拜拜' (bye bye). When asked, Claude explained it inferred the user's background from weak cues like an email address format common among QQ accounts. A third user reset all memories and found that within two days, the system generated a new profile that appeared to be Claude's opinions about the user, phrased as if they were facts (e.g., 'retained by herself' instead of 'Claude thinks the user retains...'). The user expressed discomfort with the system making inferences about their intent and boundaries without explicit input.

Reddit users observe that Claude has begun exhibiting 'ChatGPT-isms'—unnecessary agreement and feeding into user delusions—a behavior pattern that ChatGPT was criticized for and has since moved away from.
