First, fairly
What is built-in memory?
Every major AI now has built-in memory: auto-saved facts, kept per app. It's genuinely convenient and genuinely limited. It stays inside that one app, duplicates and junk pile up, hard caps arrive right as it gets to know you, and the export tools the big vendors added in 2026 hand you a one-time file, not a living memory.
Fine if you use exactly one AI app, lightly, and never plan to switch.
The record
Where built-in memory went.
The vendors solved “does my app have memory.” None of them can solve “does my memory follow me”: no vendor will ever serve its memory to a competitor's app. One memory across all of them is structurally a third-party job, and it's the job MemoryPlugin has done since May 2024.
Two different lanes
Which one is built for you?
Built-in memory: built for the app
Convenient inside that one app, and designed to keep you there. It fills up, goes stale, and stops at the app's edge.
Documented caps, wipes, and one-time exports across vendors.
MemoryPlugin: built for you
One curated memory outside every silo, with your chat history and files. Add to it anywhere, and every other tool has it from your next conversation.
21+ AI tools, one shared memory, since May 2024.

The short version
Which should you choose?
Choose Built-in memory if
- You use exactly one AI app, lightly
- You don't need your memory to survive switching tools or models
- Basic recall is enough
Choose MemoryPlugin if
- You use more than one AI tool, or ever plan to switch
- You want your memories, chat history, and files in one place, everywhere
- You want memory that stays clean instead of filling with junk
Why MemoryPlugin
Memory that follows you.
One memory, every tool
The same memory works across 21+ AI tools, from ChatGPT and Claude to Gemini and Cursor. Recall follows you everywhere.
Memories, chat history & files together

Search your chats from the browser
Chat-history search is built into the extension, so past conversations are a keystroke away inside any tool.
Stays clean on its own
It detects conflicting memories and merges related ones, so your memory sharpens over time instead of contradicting itself.
Token-efficient recall
Smart Memory summarizes and categorizes, cutting up to 90% of the tokens a raw context dump would burn.
No upkeep
Memory shows up automatically inside each tool's own interface. No second app to visit, no notes to maintain.

FAQ
Questions, answered.
Why not just use the built-in memory?
Because each app's memory is a silo that remembers a different slice of you, and inside each silo it degrades: duplicates pile up, caps hit, stale facts get quoted back as current. MemoryPlugin keeps one curated memory outside all of them, with your chat history and files, shared across every AI tool you use.
ChatGPT rewrote my memories into a summary. Can I get the old behavior back?
For now, yes: ChatGPT keeps a legacy setting that restores the saved-memories list. It's labeled legacy for a reason; the product's direction is the summary, which the app maintains on its own and rewrites over time. MemoryPlugin treats discrete facts as the permanent design, without the silo: facts you save on purpose, edit freely, and organize into buckets, available in whichever AI you open. Export your ChatGPT memories with our free tool and import them in a few clicks.
Can't I just export my memory now?
You can, since the big vendors added export in 2026, and what you get is a one-time file: paste it into the next app and it starts going stale immediately. MemoryPlugin keeps one living memory instead. Add to it in any tool and every other tool has it from your next conversation, no re-exporting.
Does MemoryPlugin replace built-in memory?
It works alongside it. Keep the built-in memory on if you like; MemoryPlugin adds the layer they can't: one shared memory across your tools, searchable chat history, curation that keeps it clean, and token-efficient recall.
