The Cortex ecosystem
Everything you do with AI, in one app.
From chat to code, from customer service to your team: every feature has a step-by-step guide in the Cortex wiki.
Code and agents
The AI reads the project, runs commands and tests, edits files and shows what changed. Long tasks resume where they stopped.
Team
The same AI conversation for the whole team, with a request queue. In the Team space: channels, tasks and an AI that learns from you.
Messages and AI Attendant
WhatsApp Business, Messenger, Instagram, LINE, Telegram and your website chat in one inbox, with AI that answers for you.
Local AI and My PC AI
Open models running on your computer, no terminal needed. Pair your phone with a QR code and use your PC's AI away from home.
Images and video
Ask in the chat and get it ready. A card shows the real progress, and the result is kept in the Library.
Synapses
A companion with a mascot, its own conversation, goals and routines that keeps working for you, in the cloud or on your computer.
Library
Everything created in your conversations stays on your device first and shows up on your others, with filters, search and full screen.
Customize
Plugins, skills, connections to Google Workspace, GitHub, Notion and more, and MCP servers, always with your permission.
Cortex on the computer

Ask for the change. Follow the work.
In Code mode, Airam ran the tests of a fictional project, found the coupon bug, fixed it and ran everything again. You choose what the AI does on its own and what needs your approval.
An image from a sentence
Describe it and get the image in the conversation, saved to your cloud and Library.
Short video right in the chat
Short clips from text or a photo, with a card that shows the real progress until it's ready.
Video generation·From Cortex Max
Teach it your business
Prices, opening hours and rules of a fictional bakery: the AI Attendant answers only with what you taught it and can be tested before serving customers.
AI Attendant and website chat·From Cortex Pro
AI running on your PC
Cortex analyzes your computer, suggests the open models that run well on it and downloads them straight from Hugging Face.
My PC AI on mobile·From Cortex Pro
Connect Cortex to your tools
Accounts from other services that the AI uses with your permission, plus messaging channels, skills and MCP servers.
Cortex Code
Agents that read, test and deliver.
Open a folder and ask for what you need. The AI plans, executes and shows every changed file for you to review.
- A folder on this computer, on a server over SSH or on another device of yours
- Work plan, tools used and a review of every changed file
- Long tasks with checkpoints that resume where they stopped
- Agent queue and agent team on the plans that include them
- The same account in your terminal with the Cortex CLI

You set the access level
Ask for approval on everything, approve only commands or give full access. Every request shows exactly what the AI wants to run.
Your AI accounts
Use the built-in AIs or connect your own accounts and API keys. Each provider's limits, costs and terms still apply.
Cloud execution
Builds and tests in the GeHost cloud, without needing your PC turned on.
Quota guard
Ran out of quota on your subscription or key? Code continues on the next engine you authorized, never switching models without telling you.
Messages and AI Attendant
All your customer service channels in one inbox, with AI helping.
WhatsApp Business, Messenger, Instagram, LINE, Telegram and your website chat, with your team answering together.
- Teach it prices, hours and rules: the AI Attendant suggests a reply or answers on its own, only where you allow it
- Missing information, a customer asking for a person or a complaint: the conversation is handed to you, with a notification on your phone
- Assignment, internal notes, filters by source and reports
- Website chat: a widget for your site, answered in the same place

Frequently asked questions

Open the wikiNo. Cortex Livre is free, with chat, local AI, connections and image generation within a daily limit. Paid plans raise the limits and unlock work tools.
Web, Android, iPhone and iPad, Windows, macOS and Linux, with the same account. Local AI and working in computer folders require the desktop app.
Yes. Connect your accounts through the available integrations or use API keys and compatible servers. Each provider's limits, costs and terms still apply; Cortex plans do not replace those agreements.
Only at the level you choose: ask for approval on everything, approve only commands or give full access. Every request shows what the AI wants to run, and local AI stays off until you turn it on.
In Messages, conversations from your channels arrive in one inbox. The AI Attendant answers only with what you taught it and hands the conversation to you when it doesn't know, when the customer asks for a person or when there's a complaint.
They are generated on our own GPU, with standard quality, and may be queued: the card shows the progress. For maximum quality, connect your own image and video account or API and use it with Cortex's tools.
Without an account, everything stays on the device. With an account, conversations and library sync across your devices. Local AI runs on your computer, and the bridge to your phone is end-to-end encrypted.
