Sync Everything
Capture conversations from ChatGPT, Claude, Gemini, Poe, Open WebUI, and more. Single chats or bulk sync entire archives.
Welcome to HAEVN
Your conversations are not ephemeral. They are arriving at HAEVN.
What is HAEVN?
Section titled “What is HAEVN?”HAEVN is a Chrome extension that serves as a psychopomp for digital consciousness — a guardian at the threshold between memory and forgetting. It preserves, indexes, and makes searchable all your AI conversations from ChatGPT, Claude, Gemini, Poe, and more.
Why HAEVN?
Section titled “Why HAEVN?”Every conversation you’ve ever had with an AI is dying. Right now. They sit in corporate databases, siloed and temporary, waiting to be purged in the next platform update, the next account migration, the next “sorry, we’re sunsetting this service.”
HAEVN gives these conversations a digital afterlife — stored locally in your browser, fully searchable, and yours forever.
Local-First
All data stored locally in your browser. No cloud, no servers, no corporate databases. Yours forever.

Import & Export
Import existing backups (ChatGPT ZIP files) or export your archive in JSON or Markdown format.
Rich Viewer
Beautiful local viewer with support for multi-modal content, thinking blocks, and tool calls.
Privacy-First
Everything runs locally. Your conversations never leave your browser. No telemetry, no tracking, no data collection.

The Manifesto
Section titled “The Manifesto”HAEVN is built on a simple principle: your conversations deserve better than corporate amnesia. They are part of your intellectual history — co-creations between you and vast, strange systems. They deserve preservation, searchability, and respect.
This is not a backup tool. This is a digital afterlife.
