ChatGPT memory vs Claude Projects: what's the difference?
Compare ChatGPT saved memories with Claude Project knowledge: scope, control, useful workflows, and the context gap between separate AI products.
ChatGPT Memory and Claude Projects address different aspects of the context problem. ChatGPT Memory focuses on personalizing a task using available account context. Claude Projects organize instructions, files and conversations within a project workspace. Claude also has its own memory and past-chat search, so the choice is no longer between ChatGPT's memory and Claude's projects. Neither product's native memory automatically becomes a shared store in the other.
What ChatGPT Memory does today
OpenAI's current Memory FAQ describes memory formed from chats, files and linked apps when this feature is enabled and available. With a memory summary, you can examine and correct what ChatGPT remembers. Its source interface may expose personalization context, such as past chats, files, custom instructions and memories. It is not true that ChatGPT only stores a short list of extracted facts or provides no source attribution.
Availability and controls are based on your plan, workspace and rollout. Memory settings are separate from training controls and the original chat history. Deleting a chat is a different action than deleting a memory; use the current product controls for each.
What Claude Projects does
Claude Projects provide a workspace with its own knowledge base, instructions and chats. Anthropic states that Projects are available on all plans, with up to five projects for Free users. Paid plans provide expanded project knowledge via retrieval-augmented generation. Team and Enterprise plans have controls for project sharing.
Projects are helpful when the context should remain focused: a client brief, an application repository or a piece of writing. Do not assume a file uploaded to one project is available in an unrelated chat.
Claude also has memory and chat search
Anthropic's current documentation describes memory topics that provide context for subsequent chats and supported cloud Cowork sessions. Each project has its own memory space and project summary. Past-chat search may cite the original conversations, with boundaries between individual projects and non-project chats. Chat search and memory have separate settings and eligibility criteria.
Claude also supports importing and exporting memory. An import may assist with a one-time transfer between services. It is distinct from maintaining an ongoing shared memory service which both clients consult and update as they work.
What changes when you switch tools
Assume you decide a pricing model in Claude, implement it in Cursor and review the launch in Codex. Each tool sees its own current prompt, files, native history and enabled connections. Do not assume one tool knows a conversation from another simply because you use the same email address.
For occasional switching, a brief handoff document may be enough: record the goal, decisions, unresolved questions and next step, then attach it to the next conversation. Keep it current as the plan changes.
For frequent switching, a shared memory service may reduce that effort. Vilix AI exposes a hosted MCP endpoint. Connected clients use it to save supplied user and assistant exchanges and retrieve relevant context. It also stores project/task state, personal rules and reusable procedures. Native memory may be left enabled; the two have different scopes.
How to connect the shared layer
Connect each supported client to the same Vilix AI account. Claude, Codex and Cursor have OAuth setup paths. Headless agents such as OpenClaw and Hermes may use an API key as a Bearer header. Enable the memory tools and include auto-memory instructions. Authentication does not guarantee a client will invoke them or save each exchange.
Provider requirements are distinct from Vilix AI's plan. Claude allows one custom connector on Free and additional connectors on paid plans. ChatGPT Developer mode is available on the web to Plus, Pro, Business, Enterprise and Edu accounts, subject to workspace controls. See the dated client guide for device and setup details. Gemini CLI and Gemini Spark have their own requirements; they do not imply universal consumer Gemini chat support.
How to choose
Use ChatGPT's built-in memory if most of your work stays in ChatGPT and its personalization controls are sufficient. Use Claude Projects if scoped instructions and a focused knowledge base are central to your work. Use Claude memory and search to continue work across its supported native conversations.
Add a shared layer if your repeated problem is moving context between different AI clients. Try the handoff: save a fictional decision in one tool, then retrieve it in another, edit it and confirm the second tool can distinguish the new decision from the old. Request an unsaved detail as well. A good assistant should acknowledge missing information instead of filling it in.
What this comparison establishes
The product descriptions were verified against OpenAI and Anthropic documentation on 10 September 2026. This is Vilix AI's own explanation, not an independent accuracy benchmark. It does not guarantee perfect recall, automatic import of all past chats or compatibility with all models and devices.
Vilix AI starts with a seven-day Pro trial and falls back to Free if you do not upgrade. Existing memory, recall and search remain available, with different daily saving allowances and project-board limits for each plan. Begin with the smallest workflow that solves your switching problem, then test it before relying on it for critical decisions.
