Chat and Code with many providers

Pick the brain. Cortex does the rest.

Each conversation picks its engine: the built-in models included in your plan, your subscription to another AI, or an API key. In Code, if your subscription or key runs out of credit or quota, the conversation can continue on the backup engine you allowed.

Built-in models included

Ecila for conversation and Airam for coding come ready to use — no key, no setup — within your plan's limits.

Your AI subscriptions

On desktop, use the account you already pay for — Claude, ChatGPT/Codex, Gemini, GitHub Copilot, Qwen, Z.ai (GLM) and DeepSeek — through each vendor's official client, kept up to date automatically.

ClaudeChatGPT · CodexGeminiCopilotQwenGLMDeepSeek

API keys and your own servers

OpenAI, Anthropic, Gemini, DeepSeek, Groq, OpenRouter, xAI, Mistral, Z.ai or any OpenAI-compatible endpoint.

Automatic switch on quota

In Code, did your subscription or key run out of credit or quota? The conversation continues on the next engine you allowed. For other errors, Cortex shows the reason and never swaps models behind your back.

Cortex Code

Ask for the change. Watch the work.

In Code mode the AI reads the project, runs commands and tests, edits files and shows what changed. Actions on your computer ask for your approval.

  • 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 that resume where they stopped
  • The same account in your terminal with the Cortex CLI

Local AI, on your computer

Run AI on your PC — and use it from your phone.

On Windows, Mac and Linux, Cortex checks your computer, shows which open models run well on it and downloads them straight from Hugging Face. No terminal: one tap to turn it on or off.

  • Green, yellow or red badge on every model, based on memory, processor and graphics card
  • Reuses the models you already have in LM Studio and Ollama
  • Turned it off? The conversation continues on the Cortex cloud by itself, with a quiet notice
  • My PC's AI: pair your phone with a QR code and chat with your computer's model at home or away, end-to-end encrypted

Teams

The same AI conversation for the whole team.

No more copy-pasting what the AI said. Bring up to 3 people into one of your chats, or create a team space with channels, tasks and an AI that learns with you.

On the phone

Shared conversation

On any plan: from the “…” menu of a chat or code, invite up to 3 people. Everyone sees the history, requests go into a queue and each person uses their own limit.

Channels and direct messages

Mentions, reactions, attachments, read receipts, photos and live “typing…”, on phone and desktop.

Team AI

Ask in the channel. If the AI doesn't know, it asks whoever decides, brings back the answer and saves it to the team memory.

Tasks and roles

“@name take care of this” becomes a task with an owner. Invite by email or link, with owner, admin and member roles.

The Team space (channels, team AI, tasks and memory) is part of the Cortex Max.

AI images and video

Ask in the chat. Get it done.

Images created from a sentence and short videos from text or a photo, with a card showing real progress until it's ready.

Images

Describe it and get the image in the conversation. Every plan includes cloud space to keep your conversation images.

Videos

5 to 8 second clips from text or a photo. The video finishes and is saved even if you close the app.

AI video is part of the Cortex Max.

On-device library

What's created in your conversations is stored on your device first and shows up on your other devices. Filters by type, source and date, search and full screen.

Customize

Connect Cortex to the tools you already use.

Plugins, skills and connected accounts on a single screen. The AI uses each connection with your permission.

Connections

Google Workspace, GitHub, GitLab, Notion, Jira and Confluence, Linear, ClickUp, Airtable, Supabase, Zapier and more, through each service's official sign-in.

Skills

Web search, image reading, memory across conversations, audio transcription and real Word, Excel and PowerPoint files.

Browser and apps

On desktop, the AI opens and tests pages in the connected browser and uses the terminal and files, always with visible approvals.

Messages: WhatsApp Business

One inbox for your WhatsApp Business chats, with AI reading, summarizing and drafting (sending always needs your yes) and your team answering together. Chats stay on your device. Cortex Pro and Max.

FAQ

The essentials, without hidden fine print.

Do I have to pay?

No. The Cortex Livre plan is free, with Chat, Code, local AI and connections within a daily limit. Paid plans raise the limits and unlock the GeHost cloud; the top plan also unlocks the Team space and video.

Can I use my ChatGPT or Claude subscription?

Yes, in the desktop app: connect the account through each vendor's official client. Usage with your subscription or key is billed by it, not by Cortex.

Where is my data kept?

Without an account, everything stays on the device. With an account, conversations and library sync across your devices, and generated images and videos are stored on the device first. Local AI runs on your computer, and the bridge to your phone is end-to-end encrypted.

Who pays when the team uses the AI?

Each request uses the limit of whoever asked. The team owner can turn on “the team pays”, with a cap per person.

Can coding actions run without me seeing them?

The executor is not hidden: actions, permissions, plan, checkpoints, files and results stay attached to the conversation. Confirmation follows your policy and system or service permissions.

Does my plan renew automatically?

Current plans are manual purchases and do not promise automatic renewal. Your account shows your plan and available access period.
