v0 memory: per-chat context, with a handoff gap
v0 is fast at going from prompt to interface. The conversation that got you there is the part that does not ship with the code.

How v0 handles memory today
v0 carries context inside a chat, and it accepts uploaded files so a prompt can reference design docs, specs, and code. Larger context degrades output quality if prompts get vague, which is why the docs push toward precise, scoped asks.
There is no cross-chat project memory. A new chat starts from what you attach and nothing else.
What v0 forgets
Every generation run is a fresh conversation with whatever you remembered to attach.
- Conversation context when you start a new chat.
- The reasoning behind a design choice, unless it is in an attached doc.
- Cross-tool continuity once the exported code lands in a repository.
- Team knowledge beyond shared docs and repositories.
The fix with MemoryRouter
Keep the reasoning in a vault and attach specs when a chat needs them. In the repo, the hooks make recall automatic, so the decision that shaped the UI is available to the agent maintaining it.

Install in the repo after export
Set up the hook package once so every later session opens with the project context, including the decisions you made while designing in v0.
Install in the exported repo
npx -y memoryrouter-claude init - 2
Store decisions, not summaries
One memory per decision with the reason attached. Search then answers "why" questions months later, which is exactly when a fresh chat cannot.
Keep design decisions alive after the code leaves v0. 14-day free trial.
