“Save this invoice and receipt together. Note that I confirmed they belong to the same client project.”
“Show me which monthly statements I have saved so far, without guessing what any transaction means.”
Cross-AI example · income tax preparation
One AI organizes the records. Another prepares the review.
DiskDrive lets a person use one assistant to build an archive during the year, then authorize a completely different assistant to use that information for a new task at tax time.

The user separately authorizes each AI.
An illustrative scenario
Jordan keeps tax preparation from becoming a yearly scavenger hunt
Jordan is a self-employed photographer. This is a hypothetical example, not a customer testimonial. Jordan wants help staying organized but does not want important records trapped inside one AI product or conversation.
- 1Jordan connects the first AI
Jordan connects ChatGPT to DiskDrive, reviews its permissions, and allows it to save files and explicit Memories.
- 2ChatGPT organizes throughout the year
It gives receipts consistent filenames, keeps an inventory of statements, and saves Jordan-confirmed notes about what each document represents. It can flag missing records without deciding how anything should be treated on a return.
- 3The records remain in Jordan’s archive
DiskDrive preserves the source files, their provenance, and the explicit notes Jordan chose to keep—even after the original ChatGPT conversation ends.
- 4Jordan authorizes a different AI
At tax time, Jordan connects Claude with read and search access. Claude does not inherit ChatGPT’s account, connection, or chat history; it can retrieve only the authorized DiskDrive records.
- 5Claude prepares a different kind of output
Claude creates a document checklist, identifies gaps or duplicates for Jordan to inspect, summarizes the archive, and drafts a preparation packet Jordan can verify before using tax software or speaking with a tax professional.
What this sounds like
Ordinary requests, two different jobs
The value comes from reusing trusted source material, not from pretending the second AI was present for the first conversation.
“Search my authorized tax-preparation archive and make a checklist of the documents that are present.”
“Draft a neutral summary for my tax preparer, cite the source file for each total, and mark anything that I still need to verify.”
What makes the handoff safe and useful
The archive transfers. The authority does not.
Each AI has its own identity, permissions, and revocation control.
Files and Memories retain provenance so later output can be checked.
Sensitive or consequential conclusions remain decisions for people.
Questions
How a cross-AI handoff works
Does the second AI see the first AI’s conversations?
No. The second AI receives access only to the files and explicit Memories the user placed in DiskDrive and authorized it to read. DiskDrive does not transfer the first AI’s private chat history.
Can the second AI receive read-only access?
Yes. The user can give the second AI only the read and search permissions it needs, review those permissions, and disconnect it later.
Does DiskDrive or the AI prepare and file the tax return?
No. In this scenario, the assistants organize user-provided records, find missing items, and draft a review packet. The user and their chosen tax software or qualified tax professional remain responsible for tax treatment and filing decisions.
What happens to the records when an AI is disconnected?
Disconnecting an AI removes that client’s access. The user-owned files and Memories remain in DiskDrive unless the user chooses to delete them.
