Privacy Guaranteed by Architecture

Plexon is designed so your code never touches a server. Every session is encrypted locally with keys only you control. Seven AI providers, but zero data retention. That is the architecture.

Your Code. Your Machine. Zero Exceptions.

Advanced Capabilities

Voice control, autonomous orchestration, and desktop automation. Beyond what a terminal can do

Encrypted Sessions

Multi-conversation history, end-to-end encrypted with keys only you control. Sessions stay on your machine, always.

Validation Feedback Loop

Every AI output is scored 0-100 for correctness, style, and completeness. Below threshold? Plexon iterates automatically.

Speech I/O & Desktop Pilot

Built-in voice input with text-to-speech output. Desktop Pilot takes full control of your computer (mouse, keyboard, and screen) for hands-free UI automation.

Orchestrator Mode

Decomposes complex projects into parallel subtasks, assigns each to the best provider and mode, and manages execution with spending limits.

Automatic Context Condensing

Long conversations never hit a wall. Plexon automatically summarizes earlier context when approaching token limits. Configurable thresholds, token buffers, and message preservation controls.

Telegram Bot Integration

Control Plexon remotely from your phone. Chat with AI, switch modes, manage sessions, trigger desktop and browser automation, all through a Telegram bot linked to your running instance.

Remote Control

Plexon in your pocket. Via Telegram.

Link a Telegram bot to your running Plexon instance and control it from anywhere. Chat with AI, switch modes, manage sessions, run desktop automation, and trigger browser tasks. All from your phone.

Switched to Architect mode. I'll plan before writing any code.

Design an auth microservice with JWT and refresh tokens

Here's the architecture plan:

1. Auth Service - JWT issuing, token validation, refresh rotation
2. User Store - PostgreSQL with bcrypt hashing
3. Gateway - Rate limiting, CORS, token middleware

How It Works

Three steps. You stay in control at every stage.

Choose a Mode

Pick from five specialized modes (Code, Auto, Architect, Ask, or Orchestrator) depending on what you need.

AI Writes & Validates

Plexon generates code, scores it for quality (0-100), and iterates automatically until it passes your threshold.

You Review & Approve

Every change goes through you. Approval gates, spending limits, and full audit trails keep you in the driver's seat.

Real-World Applications

Plexon AI powers development workflows for teams and individuals

Full-Stack Development

Build complete applications end-to-end. Choose a mode, let AI write and validate, then review and approve.

Rapid Prototyping

Use bundled skills (Website Builder, Figma-to-code, Website Cloner) to go from concept to working prototype in minutes.

Architecture Design

Architect mode plans before a single line is written. System design, API schemas, service boundaries. All reviewed before execution.

Confidential Codebases

Proprietary code stays local. Encrypted locally, zero server retention, keys only you control. Built for code you cannot share.

Plexon AI: common questions

What is Plexon AI?

Plexon AI is a desktop AI coding assistant for macOS, Windows, and Linux. It connects to seven AI providers, offers five operational modes, and runs entirely on your machine under a zero-knowledge architecture, so your source code never leaves it. Plexon AI includes voice input and output, a Desktop Pilot that can drive your screen, MCP tools with bundled skills, a Telegram bot for remote control, and per-provider spending caps.

Which AI providers does Plexon AI support?

Plexon AI supports seven AI providers, and you supply your own API key for each one. The keys are stored on your machine, not on a Plexon server, and requests travel from your machine to the provider you picked. Because you hold the keys, billing and rate limits stay under your control, and a spending cap can be set per provider. You can switch providers between tasks without moving your code anywhere, which also means a provider outage costs you a dropdown selection rather than a working day.

What operating systems does Plexon AI run on?

Plexon AI runs on macOS, Windows, and Linux as a native desktop application, and builds for each platform are published at plexon.ai. It is not a browser extension and not a web app. That distinction is what lets the Desktop Pilot drive on-screen applications, lets your source code stay on local disk where the assistant reads it directly, and lets voice input and output run without a browser permission prompt. A project never has to be uploaded anywhere for Plexon AI to work on it.

How much does Plexon AI cost?

Pricing for Plexon AI is published at plexon.ai, and it covers the application itself. Model usage is billed separately, by the AI providers, because Plexon AI runs on your own API keys rather than reselling capacity to you at a margin. That arrangement has two consequences worth knowing before you install it. You see the real cost of every request on your provider invoice, and you can set a spending cap per provider inside Plexon AI so a long autonomous run cannot quietly overspend.
