Kept

About Kept

Kept is a local-first AI chat and productivity tool that captures conversations from ChatGPT, Claude, Gemini, Grok, and Kimi and saves them as Obsidian-compatible Markdown files on your filesystem. It provides full-text search, a 3D knowledge graph, a local agent that runs over your vault, and an option to bring your own keys (OpenRouter / OpenAI / Anthropic).

Review

Kept focuses on giving you a durable, editable archive of AI conversations without relying on a cloud backend or vendor accounts. The app exports each conversation as a single .md file with stable YAML frontmatter and preserves roles, code fences, timestamps, and attachments, making it easy to integrate with note-taking and code workflows.

Key Features

• Automatic capture and sync of AI conversations into one Markdown file per chat, Obsidian-compatible with YAML frontmatter (model, timestamps, message count, etc.).
• Full-text search across the local vault and a 3D-rendered knowledge graph that surfaces related conversations and extracted entities.
• Built-in local agent that queries your vault instead of a cloud index, plus support for MCP servers and additional MCP scanners for extended providers.
• Bring-your-own-key support (OpenRouter / OpenAI / Anthropic) and open source MIT license-no account or subscription required.
• Simple install flow: desktop installer plus a browser extension for capturing provider UIs.

Pricing and Value

Kept is free and released under the MIT license, with no subscription fees or cloud account requirements. For users who prefer local storage, plain-text portability, and the ability to edit or version-control their chat archive, Kept offers strong value: the archive is immediately usable in editors like VS Code or Obsidian and can be synced with standard file-sync services if cross-device access is needed.

Pros

• Local storage of chats with a predictable Markdown schema makes the archive portable and editable.
• Supports multiple AI providers so you can capture across different model UIs into a single vault.
• Includes search, a knowledge graph explorer, and a local agent that operates over your files rather than a remote index.
• Open source (MIT) with BYOK options-good for privacy-focused users and teams who want control over keys and data.
• Quick install and straightforward file-based architecture that works with existing sync tools and git workflows.

Cons

• Search is full-text today; semantic/vector search is on the roadmap but not yet available for fuzzy retrieval.
• Capture relies on a browser extension against multiple provider UIs, which can require maintenance if providers change their layouts.
• Single-machine is the default workflow; cross-device sync requires configuring a third-party sync solution (Dropbox, iCloud Drive, Git, etc.).

Kept is best suited for users who want a private, editable archive of AI conversations-Obsidian and plain-text users, researchers, developers, and anyone who prefers file-based workflows. If you need seamless multi-device syncing out of the box or advanced semantic search today, expect some manual setup or to wait for roadmap features; otherwise, Kept is a practical local-first option for preserving and reusing chat-based work.
