Personalization

FullyCustomizable

From AI providers and themes to speech recognition and desktop automation, configure every aspect of your AI assistant to match your workflow.

Two of them follow the accent colour you chose in Windows. Others are ported from editors you already know. Then font size, density, and hiding any panel you never open.

Win11 Light and Win11 Dark: built for Windows

Win11 Light and Win11 Dark: built for Windows

Two themes that follow Windows 11's own shapes, spacing and type, not just its colors. Controls, menus and dialogs are redrawn to match the system, so Plexon sits next to your other apps instead of standing out from them.

  • Picks up your Windows accent color
  • Your wallpaper shows through the title bar and sidebar
  • Segoe UI Variable, at the sizes Windows uses
  • Falls back to solid colors on Windows 10, macOS and Linux

One Switch for What Leaves Your Machine

One Switch for What Leaves Your Machine

Plexon counts installs so we know how many people run it and on which system. A random number is created on your computer and sent when it is created, once a day, and when Plexon is uninstalled. It carries no account, no file names, and nothing from your conversations. Turn it off in the same tab.

  • Anonymous: a random number, never linked to your account
  • Not derived from your machine, so deleting the file makes you a new install
  • One switch under Settings, Advanced, Privacy
  • Turning it off sends one last message, then nothing
Telegram Bot & Integrations

Telegram Bot & Integrations

Control your AI remotely via Telegram, migrate an existing Claude Code install from the same tab, and configure image processing for optimal token usage.

  • Telegram bot for remote AI access
  • Claude Code migration: agents, MCP servers, hooks, plans, memory, and sessions
  • Image downscaling to reduce token costs
  • Figma integration for design-to-code

More Customization

Cross-Platform Desktop

Native desktop app for Windows, macOS, and Linux. Real-time streaming, rich markdown rendering with syntax highlighting, and per-session cost tracking.

Desktop Automation

Install the Desktop Automation connector to let the AI control native apps: mouse, keyboard, screenshots, the accessibility tree, and app launch. Runs locally, with every action behind tool approval.

System Command Security

Configure blocked commands (rm -rf, shutdown, reboot) and confirmation-required patterns (git push --force, npm install). Regex-based pattern matching with sensible defaults.

Settings by Conversation

Ask what a setting does and the assistant answers from the live catalog, then changes it if you want. Changes that widen file access or cost money stop and ask first, and API keys are never readable or settable from chat.

Context Condensing

Automatically condense conversation history when approaching context limits. Configurable threshold, token buffer, and messages-to-keep settings.
