Why Your AI Assistant Forgets Everything (and How to Fix It With Seed Files)

"Didn't we already go over this?" If you've said that to an AI assistant, you've hit the memory wall. Every chat session starts fresh. Your project context, coding conventions, architecture decisions — all gone. Here's why that happens and a dead-simple fix that takes 5 minutes to set up. Why AI Assistants Forget It's not a bug. It's how the technology works. Large language models don't store state between conversations. Each session gets a fresh context window — a fixed-size buffer of text the model can "see." When the session ends, that buffer is gone. Some tools (ChatGPT, Claude) add memory features, but they're unreliable for technical work. They remember that you like Python, not that your API uses snake_case responses with ISO 8601 dates and pagination cursors. For developer workflows, you need something explicit. The Fix: Seed Files A seed file is a short markdown document that you paste at the start of every AI session. It contains the minimum context the AI needs to be useful
