Later
A local-first bridge to sync your AI history directly to your personal knowledge base.
How It Works
Later is designed to be a lightweight, out-of-the-way extension that lives in your browser's sidebar. It detects when you are on a supported AI platform (Claude, ChatGPT, or Gemini) and provides a single-click extraction workflow.
Extraction Workflow
One click extracts the entire conversation, preserving code blocks, formatting, and mathematical notation.
The raw chat is converted into high-quality, standardized Markdown that works in any note-taking app.
Obsidian Sync
The core of Later is the connection to your own files. By using the Obsidian Local REST API, Later can send your extracted chats directly into your vault without you ever needing to copy-paste.
Setup Steps
- Install the Local REST API plugin in Obsidian.
- Copy the API Key from the plugin settings.
- Paste the key into the Later settings panel.
- Choose your target folder (e.g.,
AI/Chats).
AI Summarization
For long technical threads, Later can generate a structured summary before you export. This uses an OpenRouter integration to ensure you get high-quality summaries without high costs.
- Contextual: The summarizer understands the full thread.
- Structured: Generates a TL;DR, key takeaways, and action items.
- Searchable: Summaries are prepended to the Markdown file for easy indexing.
Privacy First
Later is built on the principle of Zero Data Harvesting. Your data never touches an Archit.fyi server.
Security Model
- Local Storage: Your API keys and settings are stored locally in your browser.
- Direct Peer-to-Peer: Syncing to Obsidian happens over your local network loopback.
- No Analytics: We don't track what you export or who you chat with.
