100% Local Storage
All conversations are stored in your browser’s IndexedDB and Origin Private File System (OPFS). Your data never leaves your device — not for sync, not for search, not for anything.
HAEVN is a Chrome extension that archives your AI conversations from ChatGPT, Claude, Gemini, Poe, and other platforms. It stores everything locally in your browser — no cloud, no servers, no third-party access.
Your AI conversations contain valuable information: code snippets, research notes, creative writing, problem-solving sessions. But they’re scattered across multiple platforms, locked in corporate silos, and vulnerable to:
HAEVN solves this by giving you a unified, local archive that you fully control.
HAEVN is built with privacy as the foundation, not an afterthought:
100% Local Storage
All conversations are stored in your browser’s IndexedDB and Origin Private File System (OPFS). Your data never leaves your device — not for sync, not for search, not for anything.
No Cloud, No Servers
There is no HAEVN cloud service. No backend. No databases anywhere except on your machine. We literally cannot access your conversations even if we wanted to.
No Telemetry
Zero analytics, zero tracking, zero telemetry. The extension doesn’t make any network requests except to the AI platforms you explicitly sync from.
Open Source
Every line of code is open for inspection. No hidden data collection, no black boxes. Audit it yourself or trust the community that does.
Multi-Platform Sync
Capture conversations from ChatGPT, Claude, Gemini, Poe, DeepSeek, Qwen, Grok, Open WebUI, and AI Studio. Single chats or bulk sync entire archives.
Full-Text Search
Instant search across all your archived conversations using local full-text indexing. Find any conversation in milliseconds.
Import & Export
Import existing platform backups (ChatGPT exports, Claude exports) or export your entire archive as JSON, Markdown, or plain text.
Rich Content Support
Full support for multi-modal content, thinking blocks, code execution results, tool calls, and branching conversation trees.

Your conversations are your data. Not ChatGPT’s. Not Claude’s. Not Google’s. Yours.
AI conversations are becoming a significant part of how we think, work, and create. They deserve the same care and control as any other personal data — perhaps more, given their intimate nature.
HAEVN exists because:
This isn’t about paranoia. It’s about digital self-determination.
Take control of your AI conversations.
