Personal Message Vault with AI Search
A privacy-first desktop app that imports, unifies, and lets you search your full chat history across WeChat, WhatsApp, Telegram, iMessage, and Signal — including images, links, and shared files — without uploading anything to the cloud.
power users, journalists, and small-business owners who need to find anything ever said in chat
- Local-only ingestion with end-to-end-encrypted backups you control
- Cross-platform semantic search ('who sent me the dentist address last spring?')
- Link and image extractor that rebuilds a browsable archive of shared media
- Optional on-device summaries per contact to refresh your memory before meetings
WeChat on macOS still locks chat history in encrypted SQLite; power users want ownership of their own data — and this is the most-starred pain point in that niche.
WeChat Mac 4.x encrypted local DB pain point is real and well-documented; the cocohahaha/wechat-decrypt-macos repo shows only 38★/16 forks and related zhihu article cites 1.6k★ for the broader category — solid but narrow (mainly WeChat users in CN diaspora), and the claimed 'most-starred pain point 101★' is not corroborated.GitHub - cocohahaha/wechat-decrypt-macos ↗openclaw分析微信聊天记录，只需要这个开源工具 - 知乎 ↗
Crowded adjacent space: WeMemory (paid WeChat viewer), Beeper (unified inbox, acquired by Automattic), MultiMessenger Hub, AI Chat Importer, plus multiple GitHub decrypt projects — the exact 'cross-platform + local + AI semantic search' combo has only modest whitespace.WeMemory - Local WeChat Chat History Viewer and Backup Tool ↗Beeper — All your chats in one app ↗AI Chat Importer - Backup & Archive AI Conversations ↗
Proven willingness to pay: iMyFone ChatsBack is a paid chat-recovery tool and WeMemory ships as a paid desktop app; however, the workflow is mostly one-time ingest plus occasional lookup, so recurring AI-search subscription is the only lever — narrow audience of journalists/SMB owners caps ceiling.iMyFone ChatsBack Review 2026: Does It Really Work? ↗WeMemory - Local WeChat Chat History Viewer and Backup Tool ↗
High churn risk: WeChat 4.0 (Aug 2025) broke existing export tools, and the referenced repos note DMCA takedowns of 0xlane/wechat-dump-rs and sjzar/chatlog in early 2026 — platform encryption updates and legal pressure can kill individual exporters quickly, making this a fragile category.GitHub - cocohahaha/wechat-decrypt-macos (notes DMCA and WeChat 4.x breakage) ↗openclaw分析微信聊天记录，只需要这个开源工具 - 知乎 ↗
Hard: repo itself admits WeChat 4.x auto-key extraction is unsolved, codesign breaks WeChat login, and unifying iMessage/Signal/Telegram/WhatsApp into one local schema is substantial work; local LLM search is doable but ongoing maintenance vs. platform encryption updates is a constant burden.GitHub - cocohahaha/wechat-decrypt-macos ↗ydotdog/wechat-export-macos - GitHub ↗
