Clean, Focused Interface

Clean, Focused Interface

Start every session with a distraction-free workspace. Suggested prompt cards let you jump into common tasks instantly, while the full keyboard shortcuts panel keeps power users productive.

  • Suggested prompts tailored to your active persona
  • Full keyboard shortcut reference built in
  • Activity bar for instant panel switching

A Calm Reading Experience

Replies read like a well-set page, not a chat log. Text keeps a comfortable reading width while code blocks and tables use the full column. Headings, quotes, and links sit quietly in the conversation, and each reply carries a small action row with copy, read aloud, and the time it was sent.

  • Comfortable reading width for long answers
  • Restyled code blocks, tables, and quotes
  • Copy, read aloud, and timestamp on every reply
  • Animations follow your reduce-motion preference
Five Specialized Modes

Five Specialized Modes

Switch between Code, Plan, Ask, Auto, and Orchestrator modes. Each mode tailors the AI's behavior: Plan mode explores read-only and writes one implementation plan you approve, Code mode writes the implementation, Ask mode explains concepts.

  • Code: Write and edit code directly
  • Plan: Explore read-only, then approve an implementation plan
  • Ask: Get explanations and learn concepts
  • Auto: Let the AI pick the best approach
  • Orchestrator: Delegate to specialized sub-agents
Transparent Thinking Process

Transparent Thinking Process

Watch the AI reason through problems in real time. While it works, an animated status keeps you company, and the full thinking process stays one click away, showing how the AI decomposes complex tasks before executing. A live note under the streaming reply names the tool currently running.

  • Visible reasoning and task decomposition
  • Live tool note right under the streaming reply
  • Tool Activity panel tracks every action
  • Context usage gauge with exact tokens and cost on hover
Session History & Management

Session History & Management

Every conversation is automatically saved with its mode, token usage, and full context. Each one names itself after the first exchange, so the sidebar reads like a list of topics instead of opening lines. Filter by mode, search across sessions, and resume any conversation instantly. Run more than one at a time: start a new session while another is still replying, and stop a background session from the sidebar.

  • Sessions name themselves, and a name you set by hand always sticks
  • Run multiple sessions in parallel, each with its own live status
  • Automatic session persistence with full context
  • Filter by AI mode (Code, Plan, Ask, Auto)
  • Token and cost tracking per session
  • Export sessions as JSON for external analysis
A session right-click menu with Visual Replay and Live Replay options

Visual Replay & Live Replay

Right-click any session to access powerful replay features. Visual Replay plays back the conversation like a recording. Watch every message, tool call, and code change unfold at adjustable speed (0.5x to 8x). Live Replay re-executes the session against the AI, letting you see how a different model or updated codebase would handle the same conversation.

  • Visual Replay: watch the entire session play back like a video
  • Live Replay: re-run the session against the AI with current context
  • Adjustable playback speed from 0.5x to 8x
  • Rename sessions for easy organization
  • Export full session data as JSON
  • Per-session cost and token tracking
Behavior Settings & Context Control

Behavior Settings & Context Control

Fine-tune the AI's behavior per-session from the input area menu. Toggle validation, retries, summaries, and follow-up questions. Set the maximum autonomous cycles for Auto mode and control reasoning depth. Changes apply immediately and persist across sessions.

  • Skip Validation: bypass quality checks for faster responses
  • Skip Retry: don't retry on errors. Useful for quick iterations
  • Enable Summary: include structured summaries in responses
  • Skip Custom Instructions: temporarily ignore .plexon/prompts/ files
  • Disable Questions: prevent the AI from asking follow-up questions
  • Max Cycles: set the limit for autonomous development loops (default 5)
  • Reasoning Effort: set thinking depth (Low / Medium / High) or turn it Off. Supported models reason by default

Condense Context

Running out of context window? The Condense button appears next to the context gauge when token usage is high and summarizes older messages to free up space, letting you continue long conversations without starting over. The AI intelligently compresses the conversation history while preserving the key decisions, code changes, and context that matter. You can undo a condense at any time to restore the full history.

  • One-click context compression when token usage is high
  • AI-powered summarization preserves key decisions and code context
  • Shows before/after token counts (e.g. 180k → 45k tokens)
  • Undo condense to restore full conversation history
  • Configurable auto-condense threshold in Settings → Tools

More Chat Capabilities

Autonomous Development

Auto mode runs up to 20 development cycles with quality validation (configurable threshold, default 70%), test execution, and self-correction loops. Set the goal and walk away.

Visual Understanding

Paste screenshots, photos, or diagrams for AI analysis. Image and video generation available through providers that support it.

Prompt Enhancement

AI-powered prompt rewriter that transforms simple requests into comprehensive, well-structured prompts. Adds context, clarity, architectural guidance, and edge case coverage automatically.

Zero-Knowledge Architecture

Your code never leaves your machine. The stateless server generates responses and forgets everything immediately. AES-256-GCM encryption for all local session data.
