Your AI coding session data is trapped inside one tool

AI tools remember inside their own walls. Your code lives outside those walls. That mismatch creates lock-in.

Short version: Own the working state, not just the chat subscription.

Why this hurts.

When the tool changes limits, loses history, deletes a thread, or becomes too expensive, the session state may not move with you.

How ShardStitch solves it.

01 / ShardStitch

Identify where each piece of state lives

List which facts live in repo files, local notes, provider chat, and any supported export before choosing a handoff path.

02 / ShardStitch

Preserve project evidence outside chat

Rebuild from repo files, git, notes, project memory, and available local artifacts.

03 / ShardStitch

Use a supported export for the next tool

Export to multiple tool formats so your next AI is a choice, not a prison.

04 / ShardStitch

Keep provider-only details visible as gaps

Flag decisions or messages that exist only inside a provider as gaps; do not claim local recovery can recreate them.

What the next AI receives.

  • Portable state
  • Local evidence
  • Cross-tool handoff
  • Clear trust labels

What stays out.

  • Vendor-specific history dependence
  • Hosted memory lock-in
  • Opaque summaries
  • Subscription-only continuity

Separate provider history from portable project state

Sort needed context into repository files, local notes, Git history, and provider conversation. Only the first groups are available to a local scan by default.
Save decisions or constraints that must survive in a project note or handoff before the session is lost. Do not rely on a provider chat being exportable.
Generate a destination format that the next client can read, or paste the packet into a web chat. Verify the destination workspace independently.
Mark anything that exists only in the old provider session as unavailable until exported or copied. Do not imply that a local handoff unlocks hidden vendor history.

FAQ.

Can ShardStitch unlock or export private provider chat history?

No. It helps assemble local project context and supported handoff output; it does not unlock private provider records or guarantee access to an old chat.

Does a portable packet include every decision from the old session?

Only decisions that were captured in accessible project artifacts or included in the packet. Conversation-only details may be absent and should be treated as unknown.

Privacy and history are different from portability.

A vendor's privacy controls can govern data handling without providing a verified handoff to another tool. Chat branching and export also depend on the original service and a usable conversation. Review the current Cursor data-use explanation or ChatGPT export instructions for those product-specific controls. For cross-tool continuation, make the repository state, checks, and unknowns portable separately from the transcript.
