Guides

One question per page, answered first, with the setup in full and a table of the options, including the ones that are not supermemory. Each page shows the date its facts were checked.

• How do I give Cursor long-term memory?Cursor keeps the Rules you write, but its Memories feature is gone and nothing from a chat follows you between repositories or to Claude Code and Codex. The ways to add long-term memory, with the supermemory plugin set up in two commands.
• Does Codex have memory across sessions?Codex has an official Memories feature, off by default and local to one machine, and reads AGENTS.md every session. How to add memory that is searched on each prompt and shared with Claude Code, Cursor and OpenCode, with the codex-supermemory plugin.
• Which memory plugin should I use for OpenCode?OpenCode starts every session cold. The memory plugins that exist for it, what each stores and where, and how to install opencode-supermemory, which works on OpenCode 1 and 2.
• How do I add long-term memory to a LangChain agent?LangChain's checkpointer and Store keep what you put in them. How to add memory that extracts facts and keeps a user profile, with supermemory in a LangChain chain or a LangGraph node, and how LangMem, Mem0 and Zep compare.
• How do I add persistent memory to a Vercel AI SDK app?The AI SDK keeps nothing between requests. How to add memory with the supermemory middleware in one line, give an agent memory tools, or use a bash-style memory tool in serverless functions, and how that compares with saving messages yourself or Mem0's provider.
• How do I give an AI support agent memory of past tickets?Retrieval over past tickets finds similar cases; a memory of each customer tells the agent who it is talking to. How to get both with one namespace per customer in supermemory, with ticket metadata, filtered search and a maintained profile.
• How do I build user profiles for LLM personalization?A profile is what the model should know on every turn, whatever the question. Why search cannot deliver it, what a supermemory profile contains, how to fetch it in one call and attach it to the prompt, and how Mem0, Zep and Honcho compare.
