Open Bridge AI

Open Bridge AI is a contextual AI workspace for Obsidian.

It connects notes, selected text, files, folders, AI responses, and local or cloud AI backends, so you can work with AI inside your vault without repeatedly copying context into a separate chat window.

The core idea is simple: when you say "this file", "this paragraph", or "that AI answer", Open Bridge AI helps the AI understand exactly what you are referring to.

Key Features

• Chat with Claude, Codex, or a custom CLI from inside Obsidian.
• Connect Codex through subscription login or API key model gateways.
• Support OpenAI-compatible providers such as OpenAI, OpenRouter, LiteLLM, One API, Ollama, and private gateways.
• Add files and folders from the file explorer as AI context.
• Add selected Markdown text as context, including file path and nearby lines.
• Quote full AI replies, selected AI text, or individual AI paragraphs back into context.
• Manage active context with lightweight context chips.
• Save sessions as Markdown inside the vault for search, review, and long-term memory.
• Show live execution progress for supported CLIs.
• Switch the interface language between Chinese, English, and Japanese.

Why Open Bridge AI

Most AI chat plugins start with an empty conversation.

Open Bridge AI starts from your workspace. It is designed for people who organize real work in notes: research, product planning, design decisions, technical documentation, writing drafts, project knowledge, and team memory.

Instead of asking the user to explain everything again, Open Bridge AI lets the user explicitly attach the current working context.

Installation

Community plugin install

After the plugin is accepted into the community plugin directory:

1. Open Settings.
2. Go to Community plugins.
3. Choose Browse.
4. Search for Open Bridge AI.
5. Install and enable the plugin.

Manual install

1. Download main.js, manifest.json, and styles.css from the latest release.
2. Create this folder in your vault:

.obsidian/plugins/open-bridge-ai/

3. Put the three files into that folder.
4. Restart Obsidian or reload community plugins.
5. Enable Open Bridge AI in Settings -> Community plugins.

Usage

1. Open the Open Bridge AI view from the ribbon icon or command palette.
2. Choose a backend: Claude, Codex, or Custom.
3. Add context before asking:
   • Right-click a file or folder and choose Add to Open Bridge AI context.
   • Select Markdown text, then right-click and choose Add selection to Open Bridge AI context.
   • Quote a full AI answer, selected AI text, or one AI paragraph back into context.
4. Ask your question in the chat box. The active context is sent together with your message.
5. Start a new session when switching topics, or continue the current session when you want the AI to remember the previous discussion.

Context Workflow

Open Bridge AI is designed around explicit context references.

You can:

• Right-click a file or folder and add it to Open Bridge AI context.
• Select text in a Markdown file and add it to context.
• Quote an entire AI response back into context.
• Select part of an AI response and quote only that fragment.
• Hover an AI paragraph and quote that paragraph as context.

The next message automatically includes the active context, so short follow-up prompts become useful:

Summarize this.
Rewrite this paragraph.
Compare these two files.
Continue from that answer.
Turn this into a clearer product note.
