Tapestry PRM vs. ChatGPT and Claude memory
ChatGPT and Claude remember context about you to personalize their answers. Tapestry PRM remembers the people you know, built from your own email, calendar, messages and contacts, and keeps that memory on your device. They work well together: you can give either kind of assistant read-only access to Tapestry.
The short answer
- About you, or about the people you know. Assistant memory personalizes answers for you. Tapestry organizes your relationships: each person, each organization, and your history with them.
- Their systems, or your device. ChatGPT and Claude store memory on their providers’ systems. Tapestry keeps its memory in a folder on your device, with no account.
- The originals, kept. Tapestry keeps every message, email and meeting it read, so you can open the original evidence behind any detail.

Use them together
Turn on assistant access in Tapestry and an assistant that supports MCP, such as Claude, can read your relationship memory to prep you for a meeting or find who can help. Access is read-only and off until you turn it on, and Tapestry records every access on your device before anything is read. A cloud-based assistant sends what it reads to its provider under that provider’s terms; a local assistant can keep it on your device.
Which to use for what
- Use assistant memory for your own preferences, writing style and ongoing projects.
- Use Tapestry for the people you know: who they are, where they are, what you last talked about, and who can help.
- Use both when you want an assistant’s help with a relationship, grounded in your own history.
Questions
Does Tapestry PRM replace ChatGPT or Claude?
No. Keep using the assistant you like for writing and thinking. Tapestry is the relationship memory it can read, with your permission.
Does Tapestry send my data to OpenAI or Anthropic?
Not on its own. Tapestry’s own features don’t use cloud AI providers. If you turn on assistant access and connect a cloud assistant, that assistant sends what it reads to its provider under the provider’s terms. A local assistant can keep it on your device.
Which assistants can read Tapestry?
Assistants that support MCP, such as Claude, through Tapestry’s read-only MCP server on your device. Support for local MCP servers varies by assistant.
