Google added chat import from ChatGPT, Claude, and other assistants to Gemini. You can upload your entire chat archive. Or simply ask your old chatbot to provide a summary of preferences from its memory, then feed it to Gemini.
The mechanics are simple. Export your chat archive from the old assistant, upload the ZIP to Gemini (up to 5 files per day, up to 5 GB each). For memory transfer — copy a special prompt, paste it into the old chatbot, get a summary, feed it to the new one.
Anthropic launched a similar migration for Claude in early March. Chatbots are starting to compete not just for new users but for each other's — poaching them along with history and habits. Which I think is very convenient for users. Having shared context across services.
A similar scenario already played out in streaming: Apple Music, Spotify, and YouTube Music took turns adding playlist import from each other. Now the same thing is starting in AI.
