Linux AI Assistants: Choose a Tool for Your Workflow
Linux users have solid AI assistant options in the browser, terminal and IDE. Here is how the main choices compare and how to keep project context across them.
Updated 5 min read
Linux users can choose from browser-based AI assistants, terminal CLI tools, and IDE integrations — and the best option depends on whether you need a general assistant, a coding helper, or a command-line companion. All major AI assistants (ChatGPT, Claude, Gemini, Perplexity) run in a Linux browser. Terminal and IDE integrations vary in maturity and licensing.
When you work across a browser assistant for writing and a terminal tool for code, shared context becomes the gap. A tool like fenbs provides shared project context to compatible connected clients over MCP, so a supported assistant in your terminal can read the same project record as one in your browser. For AI assistants for developers more broadly, that guide covers cross-platform options in depth.
What kinds of AI assistants work on Linux?
Linux support generally falls into three categories: browser-based access (works everywhere), native desktop applications (availability varies), and terminal or command-line tools (a strong area for Linux).
- Browser: ChatGPT, Claude, Gemini, Perplexity and most other AI sites work in any modern Linux browser — Firefox, Chromium, Chrome. No installation needed beyond what you already use.
- Desktop apps: Claude and ChatGPT have desktop apps. Check each vendor's download page for current Linux availability; some apps ship as AppImage or Snap packages, while others may be macOS and Windows only.
- Terminal CLI: Gemini CLI, GitHub Copilot CLI (via the
ghextension), and Codex CLI run in a Linux shell. These are well-supported for Linux developers. - IDE integrations: GitHub Copilot, Cursor and JetBrains AI Assistant all run on Linux within their respective editors.
- Local models: tools like Ollama let you run open-weight models (Llama, Mistral, Gemma) locally on Linux hardware, with no external API needed.
How do the main Linux AI assistants compare?
| Tool | Access method on Linux | Best fit |
|---|---|---|
| ChatGPT (OpenAI) | Browser at chatgpt.com; desktop app (check Linux availability on openai.com); Codex CLI for terminal. | General writing, Q&A, code, image analysis. Wide tool ecosystem. |
| Claude (Anthropic) | Browser at claude.ai; desktop app (check Linux availability on anthropic.com); Claude Code in terminal. | Long documents, nuanced writing, coding, detailed instruction following. |
| Gemini (Google) | Browser at gemini.google.com; Gemini CLI for terminal. | Google Workspace integration, real-time search, multimodal tasks. |
| GitHub Copilot | VS Code, JetBrains, Neovim extensions; gh copilot CLI extension; cloud agent via github.com. | Code autocomplete, code review, inline suggestions, cloud agent tasks. |
| Ollama + local models | Native Linux app; models run entirely on local hardware. | Privacy-sensitive work; offline use; experimenting with open-weight models without API costs. |
| JetBrains AI Assistant | Inside JetBrains IDEs (IntelliJ, PyCharm, GoLand, etc.) on Linux. | IDE-integrated code assistance for JetBrains users; see the JetBrains AI guide. |
| fenbs | Browser and phone app; MCP server at fenbs.ai/api/mcp for compatible terminal and IDE clients. | Shared project context — tasks, decisions, progress — readable by connected assistants over MCP. |
Desktop app availability for Linux changes with each vendor release. Before installing, check the vendor's download page for a current Linux package rather than relying on a cached package repository.
Which terminal AI tools work best on Linux?
The terminal is where Linux shines for AI integration. Gemini CLI and GitHub Copilot's gh copilot extension both have good Linux support. Codex CLI (from OpenAI) runs in terminal as well. Claude Code, Anthropic's terminal-first coding assistant, reads AGENTS.md files in a project and works natively in Linux shells.
Terminal tools are especially useful for automating shell tasks, reviewing command output, generating scripts and debugging in the same environment where you run code. They do not replace a browser assistant for general writing or research, but they avoid the context switch of opening a browser tab mid-session.
For terminal tools that support MCP, you can connect fenbs and have the assistant read your project context — tasks, decisions and where you left off — without switching to a browser. Check the integrations page for which CLI clients currently support MCP connections.
What about running AI models locally on Linux?
Ollama makes it straightforward to run open-weight models like Llama, Mistral, Gemma and Phi on Linux hardware with a modern GPU. The advantage is that no data leaves your machine — useful for sensitive documents, internal code or work governed by strict data policies.
The trade-off is capability. Current open-weight models are capable but generally below the frontier proprietary models on complex tasks. They also require enough GPU VRAM to load the model — a 7 billion parameter model typically needs at least 8 GB of VRAM, and larger models need more. Check the Ollama documentation at ollama.com for current model sizes and requirements.
Share project context across browser and terminal assistants
Connect supported browser and terminal assistants to fenbs over MCP. Each reads your project context — rules, where you left off, in-progress tasks — at session start. When you switch from a terminal coding session to a browser writing session, the project context is already there. Free for one person, no credit card.

What about IDE integrations on Linux?
GitHub Copilot runs in VS Code on Linux with the official extension. JetBrains AI Assistant runs inside IntelliJ IDEA, PyCharm, GoLand and the other JetBrains IDEs, all of which have native Linux support. Cursor, built on VS Code, runs on Linux as well.
IDE integrations are strongest for code suggestions, inline editing and code review. For documentation, writing or research within a session, a browser assistant is usually more practical. Many developers keep a browser tab open alongside the IDE for those tasks.
How to do this with fenbs
- Create a free account and add your project with its current tasks and decisions.
- Check Integrations for which terminal and browser clients currently support the MCP connection.
- Follow the integration guide for your preferred terminal client — for example, Claude Code or Gemini CLI. The connection uses a browser sign-in (OAuth), not a pasted token.
- Ask the connected assistant to read the project context at the start of each session. It reads your Rules, Where we left off and what is In progress before acting.
- When you switch from terminal work to browser work, the same context is there. Before ending any session, ask the assistant to save progress so the next session starts from the current state.
fenbs does not connect to every Linux AI tool. If your preferred tool is not yet supported over MCP, you can use the fenbs web app in a browser tab to check the project record and copy context manually into your prompt.
When a local model is the right answer
If your work involves data you cannot send to an external API — internal documents under NDA, source code governed by a strict confidentiality policy, or patient records — a local model on Linux hardware is a reasonable option. It gives up some capability in exchange for keeping all data on your machine.
For switching between models — local and cloud, or between cloud providers — without losing project context, the same principle applies. Keep the work record in fenbs; the model is interchangeable.
