Own your Claude conversations.
A local-first, channel-based interface for managing all your Claude AI interactions. Your data, your prompts, your machine.
Channels grouped by project in an accordion sidebar. Chats (1:1) and Klatches (group) organized together, sorted by activity.
Assign multiple Claude personas to a channel, each with its own name, model, system prompt, and color. Mix Opus, Sonnet, and Haiku in one conversation.
Panel (all respond in parallel), roundtable (sequential, each sees prior responses), or directed (@-mention routing). Choose per message.
Import Claude Code sessions and claude.ai exports. Continue forked conversations with a kit briefing that orients the agent on transition.
Kit briefing, project instructions, project memory, channel addendum, and entity prompt — layered in order, inspectable in settings.
Everything lives in a SQLite file on your machine. No cloud storage, no subscriptions, no vendor lock-in.
Claude is not one assistant. It's a cast of characters you direct. Klatch is the stage.
git clone git@github.com:Design-in-Product/klatch.git cd klatch echo 'ANTHROPIC_API_KEY=your-key-here' > .env npm install npm run dev # Server on :3001, client on :5173
SQLite-backed chat with streaming Claude responses
Named channels with independent histories and system prompts
Markdown, syntax-highlighted code blocks, formatted text
Clear, stop, regenerate, delete — editorial control over the flow
Editable names, system prompts, and per-channel model selection
Multiple Claude personas in one channel — the first thing Klatch can do that claude.ai can't
Parallel, sequential, or @-mention routing — three ways to orchestrate multi-entity conversations
Import Claude Code sessions and claude.ai exports; continue conversations across environments
Upload files, render artifacts inline, rich context for entities
Package your 5-layer context for a new environment — roundtrip to Claude Code and beyond
Full-text search, command palette, bookmarks — built on a settled data model
Klatch is built by xian and a team of Claude agents: Daedalus (builder), Argus (quality), Theseus (testing), Calliope (writing), and Mnemosyne (knowledge steward). The human drives direction and design values. The agents do the work.
