OpenAI silently removed Study Mode from ChatGPT

Article Summary

A ChatGPT user reports that OpenAI quietly removed the Study Mode feature, which guided learners through topics in a structured, Socratic-style format. No official announcement or explanation was given by OpenAI for the removal, continuing a pattern of silent feature deprecation.

Discussion

• Several users noted Study Mode was likely just a system prompt under the hood, suggesting OpenAI may have deprecated curated “modes” in favor of free prompting
• Mixed experiences: some found it lost track of its own lesson plan mid-conversation, others noted arithmetic errors when scaffolding AIME math problems
• OpenAI’s pattern of silently removing features came up repeatedly — the “Robot” personality, Chat mode from Codex VSCode extension, and others
• A broader thread emerged questioning whether ChatGPT has generally degraded — feeling more boilerplate, sycophantic, and confidently wrong
• Alternatives mentioned: Kagi Assistant’s still-active Study mode; some suggest prompting ChatGPT as a study coach achieves the same result
