Use Case Recommendations
Best for: Lumi
Lumi is a persistent memory layer that spans ChatGPT, Claude and Gemini, so context you establish once is available in all three rather than trapped in whichever chat you happened to open. The problem it names is concrete and familiar: forty-five minutes spent giving an assistant project context, then a new conversation tomorrow that starts from zero; a switch from one model to another for a task it handles better, leaving the entire history behind; and usage limits burned faster on long projects because every message re-sends the whole conversation. Lumi's answer is a vault you write to from any of the three assistants and read from in any other, with memories organised into vaults and collections in whatever hierarchy you think in, and semantic search that retrieves by meaning rather than keyword. The efficiency claim follows from the retrieval model — instead of re-sending an entire history each turn it retrieves only what is relevant, which the site puts at up to 95% fewer input tokens on long projects, keeping costs flat as a project runs for months. On the privacy side it states that memories are end-to-end encrypted, never sold and not used to train AI, which is the necessary assurance for a product that by design holds the context you consider worth keeping. It is free to start.
Ideal use cases:
- •Teams or individuals who need one memory vault shared across chatgpt, claude and gemini
- •Teams or individuals who need save in one assistant, retrieve in another
- •Teams or individuals who need vaults and collections for hierarchical organisation
- •Teams or individuals who need semantic search that retrieves by meaning
- •Anyone focused on ai-memory workflows
- •Anyone focused on chatgpt workflows
Best for: Segue
Segue solves one narrow, extremely common annoyance: every AI assistant keeps your working state in its own silo. You plan in one, build in another and draft in a third, and each holds real context — the brief, the constraints, the decisions so far — that none of them will hand to the next. Segue lets you save a block of context in one assistant and get a short handle back, then load it by that handle in another. It works over MCP, so Claude, ChatGPT, Cursor and any other MCP client are all valid endpoints, and there is a web editor for reading, editing and exporting saved contexts as Markdown. The design commitment that stands out is the data policy, stated explicitly rather than buried: reading, searching, editing, exporting and deleting your saved contexts are free on every plan in every billing state, including after a subscription lapses. If you exceed a cap, only new saves and new shares pause — everything already stored stays readable and exportable, and every share already sent keeps working. Sharing out is the paid feature; reading a context someone shared with you is never paywalled and never requires an account. At $5/month or $48/year for the Pro tier, it is priced as a utility rather than a platform, and the free tier's 20 contexts and 2 connected clients function as the trial.
Ideal use cases:
- •Teams or individuals who need save a context block in one assistant, load it by handle in another
- •Teams or individuals who need works with claude, chatgpt, cursor and any mcp client
- •Teams or individuals who need web editor with search and markdown export
- •Teams or individuals who need sharing with up to 25 people per context on pro
- •Anyone focused on mcp workflows
- •Anyone focused on context workflows
