Compare
Your project memory, beyond one app.
ChatGPT and Claude can remember across conversations and keep project context separate. Unforgetter focuses on a maintained record that connected agents can share.
Start with the memory you already have.
If your existing tool keeps the context you need and you are happy working there, built-in memory may be enough. A separate service becomes useful when you want the same current record available across tools, with a clear update and access process.
Compare the actual differences.
| Capability | ChatGPT | Claude | Unforgetter |
|---|---|---|---|
| Memory across conversations | Built-in memory and project context. | Built-in memory and separate project summaries. | Retrieval from a published workspace memory. |
| Project separation | Project-only memory can exclude conversations outside that project. | Separate project memory. | Connection grants restrict authorised collections and material. |
| Across different vendors | App-managed memory; transfer and import options differ from a shared live record. | App-managed memory; transfer and import options differ from a shared live record. | The same published memory is available through MCP to connected clients. |
| Changed decisions | Can use updated context; inspect the product’s memory controls. | Can use updated context; inspect the product’s memory controls. | Source records can mark current and superseded decisions with their history. |
| Setup | Enable the relevant memory/project settings. | Enable the relevant memory/project settings. | Guided private alpha; client support is checked during setup. |
| Maintenance | Managed within ChatGPT. | Managed within Claude. | Cloud proposals and opt-in maintenance are implemented; automatic local capture is verified in a scoped internal Codex pilot. |
Use the two together.
Your agent’s built-in memory can still be useful. Unforgetter provides an additional record for work you want to carry across tools. If the two disagree, inspect the dated source and correct the record rather than assuming either one is always right.
