Everything in the box
The full feature set. Skim now, dig later: every card opens a deeper page.
Skills
Self-Improving Skills
Plexon grows its own knowledge library while you work. After every session, or on demand, a small curator agent quietly reviews what happened, saves new skills worth keeping, refines existing ones, retires the stale, and protects everything you've pinned. You get smarter assistance over time without writing a single instruction by hand. One-click toggles in the Skills sidebar; full transparency via the curator history viewer.
Learn more →Automation
Schedule: Cron for Agents
Run any sub-agent on a cron expression or simple interval. Every N months, days, hours, minutes, or seconds. Failed jobs auto-disable after 3 consecutive failures, live OS desktop notifications fire when work completes, and every job dispatches to the same agents that answer chat. "Weekly metrics report Monday 9 AM" or "every 6 hours summarise PR review queue" becomes a single click in the Schedule sidebar.
Learn more →Workflows
Dynamic Workflows
Turn a trigger into a small graph of steps and let Plexon run it. A schedule, an incoming message, a webhook, or a button starts the flow; each step calls a connector, asks the AI, runs an agent or persona, branches on a condition or expression, loops over a list, transforms data, waits for a reply, or asks you to approve. Build it on the canvas or describe it in chat, test any step on the spot, then review before it runs. The engine runs locally, remembers every run, and sends each message at most once. Ships a Greet new contacts example, and personas bring their own, like the Stock Trader pre-market briefing and alerts that stay quiet until something moves.
Learn more →Monitoring
Dashboards
Build a board of widgets that read from your tools, the AI, or a workflow, and keep themselves up to date. Stat tiles, charts, gauges, tables, even full HTML you can edit with AI. Add a parameter like a city and the whole board follows. Turn on monitoring and it refreshes in the background. Ships a Weather & City board and a Global Intelligence board, both filled from free public data the moment you open them.
Learn more →Agents
Orchestrator & Sub-Agents
Break complex tasks into parallel subtasks executed by independent sub-agents. Wave-based scheduling, inter-agent bulletin board, per-agent cost tracking, and @mention invocation.

Side Questions
Ask about the conversation while the AI keeps working; the answer streams into a side card and never touches the task.
Shell Commands
Start a message with ! to run it as a shell command; the output renders as a terminal card and feeds the AI's context on your next message.
Graph-Aware Code Review
Plugin-powered PR review that builds a persistent Tree-sitter knowledge graph of your repo and surfaces only the files a diff actually touches.
Dynamic UI Widgets
AI responses render as rich interactive components (grids of recipe cards, macro tables, meal-plan timelines, togglable checklists, stat tiles, and forms) instead of walls of markdown.
Word & Excel in Chat
Two bundled MCP servers let the AI read, create, and edit Microsoft Word (.docx) and Excel (.xlsx) files directly from chat.
Read Any Document
Point Plexon at a Word doc, spreadsheet, slide deck, PDF, EPUB, OpenDocument file, RTF, email, or a LaTeX or reStructuredText file and it reads the contents as Markdown you can ask about.
Embedded Browser
A split-pane webview docked next to the chat.
Session Lock & App Lock (Premium)
Lock a chat with a passcode and its messages are encrypted with a key derived from it. Unlock with Touch ID or Windows Hello. An optional app lock guards the window at launch.
Migrate from Claude Code
Bring your agents, MCP servers, hooks, plans, memory, and every conversation across. Each plan lands in the project it was written for.

Switching
Never break your work
Your setup does not have to stay where you left it. Plexon imports your memory, your plans, and your sessions from other assistants, starting with Claude Code, along with the agents you wrote, your hooks, and your MCP servers. Point it at the folder, pick what to keep, and each piece lands in the project it belongs to.
- It finds your installSettings reads the global ~/.claude folder. Open a repo Claude Code set up and Plexon offers that project on the spot.
- You pick what to keepEvery component arrives counted. Plans open into their own list, so the drafts you never approved can stay behind.
- Each piece lands where it belongsPlans and sessions go to the project they were written for, not one global pile. The results screen names every destination.

FAQ
Frequently asked questions
Everything you need to know about Plexon's privacy-first architecture
How is Plexon different from GitHub Copilot or Cursor?
Plexon offers 6 specialized AI modes (vs 1), 156 agents across 8 professional domains, built-in browser and desktop automation, AI commit messages, prompt enhancement, parallel sub-agent orchestration, a dual skills system, hooks automation, voice I/O, Telegram bot, and a 100% stateless server. Your code never leaves your machine. Our server stores nothing.
Does your server store my code?
No. Our server is 100% stateless. It processes your AI request using 31 dynamically-assembled system prompt sections and immediately discards all data. Zero storage, zero logging, zero retention. API keys are AES-256-GCM encrypted in transit and never persisted.
Where is my conversation history stored?
Entirely on your local machine, encrypted with AES-256-GCM. Plexon stores them locally. You own your data completely.
Can I lock a single chat so nobody else can read it?
Yes. Lock a chat with a passcode and its messages are encrypted with a key derived from that passcode, so nothing reads them without it. Open it again with the passcode, with Touch ID on macOS, or with Windows Hello on Windows. A locked chat still shows in the sidebar by name with a lock badge, and stays out of exports and live shares until you unlock it. There is also an optional app lock that asks for a passcode before the window becomes usable on launch: that one is a gate against someone at your desk, not disk encryption. Both are local, nothing about them reaches a server, and a forgotten session passcode cannot be reset by anyone, us included. Turning a lock on needs Premium; unlocking, changing a passcode, and removing a lock work on any plan.
What LLM models does it support?
Plexon supports 9 providers: the managed Plexon provider, Anthropic (Claude Fable 5, Opus 4.8), OpenAI (GPT-5.3, Codex), Google Gemini (3.1 Pro/Flash, Nano Banana Pro 2), Moonshot (Kimi K2.5), OpenRouter (100+ models), Qwen (Qwen3.6 Plus, Qwen3 Coder Plus), Z-AI, and Claude Desktop. You can configure separate providers for execution and planning modes.
How does Orchestrator mode work?
Your task is decomposed into 2-5 subtasks by the AI. Up to 3 sub-agents execute in parallel, each with its own session and cost tracking. Results are synthesized by the planning provider into a coherent response. Complex tasks complete in ~45 seconds vs 2+ minutes sequential.
How does autonomous mode work?
The client orchestrates multiple development cycles. Each cycle: the AI generates code, quality is validated (0-100 score), tests are run, feedback is generated, and the AI iterates. Cycles continue until the quality threshold is met (default 70%, configurable) or the max cycle count is reached (default 5, max 20). Per-cycle cost tracking is shown in the UI.
What is the Skills system?
Skills are reusable instructions (coding standards, workflows, domain knowledge) that persist across sessions. Your custom skills are simple text files that work with every provider. Anthropic-native skills handle xlsx, docx, and pdf and run on the server. Both kinds coexist in a single request.
Does it work with my existing Claude skills?
Yes. Plexon uses an open skill format that other AI assistants share. Copy skills you have from other AI assistants into Plexon and they work immediately.
What platforms are supported?
Windows (x64, ARM64), macOS (Intel, Apple Silicon), and Linux (x64, ARM64). The desktop app is built and distributed for all platforms with auto-update support.
Can I self-host the server?
Yes. You can run your own stateless server instance. Either way (our hosted server or yours), no data is retained server-side.
How does browser automation work?
Plexon AI controls browsers via Playwright MCP: navigate, click, type, scroll, and screenshot. You can use your real Chrome profiles with logged-in sessions. The AI always asks for your permission before navigating to new URLs.
Can I use Plexon from my phone?
Yes. The Telegram bot integration lets you chat with Plexon, manage sessions, send images for analysis, and monitor what the AI is doing. All from your phone, in any country, using your usual Telegram account.
Is Plexon AI only for developers?
No. While Plexon excels at coding, it ships with 156 agents spanning 8 professional domains: software engineering, marketing & growth, sales & business, legal & compliance, data analytics, game development, research & creative, and specialized markets including China/Asia platforms. Marketers, lawyers, sales teams, and researchers all have dedicated agent personas.
What is prompt enhancement?
Prompt enhancement is an AI-powered rewriter that transforms simple requests into comprehensive, well-structured prompts. It adds technical context, resolves ambiguities, suggests design patterns, and defines quality criteria. All before your request reaches the main AI model.
Can I automate actions before or after tool execution?
Yes. The hooks system lets you run shell commands or HTTP webhooks before or after any tool call. Use pre-hooks to validate inputs or block dangerous operations, and post-hooks for audit logging, CI/CD triggers, or notifications. Hooks support regex tool matchers and can be scoped globally or per-project.
Can Plexon help me shop and compare prices?
Yes. The Personal Shopper persona searches products across stores, compares prices and features, suggests cheaper alternatives, and keeps a shopping list and budget. Connectors cover Google Shopping and web retailers, a Shopify store, eBay, an affiliate buy-link hub, and Skroutz price comparison in Greece. Buying is a hand-off: Plexon gives you a link to finish checkout on the store and never places an order.
I already use Claude Code. Do I have to set everything up again?
No. A migration wizard reads your existing Claude Code install and brings it across: custom agents, MCP servers, hooks, plans, your CLAUDE.md and user rules, project memory, and the full conversation history. Plans land in the project each one was written for and keep the approved or draft status they had, and the drafts you never approved can be left behind with one button. Everything imported is labelled with where it came from, so you can search for it, review it, or clear it out later. Nothing in your ~/.claude folder is moved, edited, or deleted, so Claude Code keeps working.
