About

Duotang is a free Chrome tab manager and workspace extension that organizes browser tabs into project-based workspaces. Tabs stay alive across workspace switches, so half-typed Gmail drafts, scroll position, video timestamps, and AI chat sessions all survive. Switch between Work, Personal, and Travel instantly — nothing reloads, nothing is lost. Local-first: zero telemetry, zero analytics, no account required.

About

MemPalace is a local-first storage and retrieval system for AI workflows, built to give AI a memory while keeping the user’s words under their own control. It stores conversations verbatim instead of reducing them to summaries, then organizes that memory into a navigable “palace” structure inspired by the ancient memory palace technique. Conversations can be arranged into wings for people, projects, or topics, with rooms and drawers used to make information easier to locate, narrow, and retrieve later. It is designed for people who believe their words are theirs, with local-first storage, zero telemetry, and a privacy-focused approach that keeps memory on the user’s machine. MemPalace supports AI workflows through MCP tooling, including tools for palace reads and writes, knowledge-graph operations, cross-wing navigation, drawer management, and agent diaries.
