AgentChatVault — Local AI Chat Archive Viewer

Automatically archive hard-to-export AI chats from OpenRouter, ChatGPT, and more into a local, searchable vault.

Problem

AI chat logs are scattered across platforms, and many (like OpenRouter) lack a simple export feature, making it impossible for users to review, search, or migrate important conversations. One developer built a local archiving tool specifically because 'AI chats are hard to export,' confirming a clear and common need. Existing solutions either rely on platform exports or manual copy-paste.

Solution

A local desktop app or browser extension that scrapes user conversations from OpenRouter, ChatGPT, and more via API or page parsing, storing them in a unified local SQLite database. It offers full-text search, tagging, and export to Markdown/JSON. Manual JSON import is also supported.

Users

Researchers, writers, developers, and students who frequently use multiple AI chat platforms.

MVP

Auto-scrape from OpenRouter and 1-2 other major platforms; local SQLite storage; full-text search UI; export to Markdown; manual import support.

Revenue

Freemium: basic local archive free; paid tier adds more platforms, cloud sync, encrypted backup, and team sharing.

Why now

Multi-platform AI use is the norm, yet data sovereignty and portability are still overlooked. An indie developer can quickly build a lightweight local tool without relying on official exports.
