Cortex AI IDE review
A capable BYOK coding IDE for indexed, reviewable agent editing across Windows and Linux.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Cortex AI IDE is a desktop coding environment for developers and small teams who want AI-assisted work across an entire project. Its agent can plan tasks, search indexed code, edit multiple files, execute terminal commands, verify results, and present reviewable diffs. The core coding experience is available on Windows and Linux, with code, prompts, API keys, and project memory kept locally. It is particularly suited to developers who want model choice without being tied to one provider.
The free plan provides a substantial base for coding, including agent workflows, full-codebase indexing, semantic search, a native terminal, reviewable diffs, extensions, project memory, and provider connections. Pro Monthly costs $10 per month and adds image text extraction, semantic code search, web search, voice prompts, all LLM models through BYOK, and full IDE features. Pro Yearly costs $80 per year and includes everything in Pro Monthly, plus priority support and early access features. The subscription covers platform services; model usage remains separate and is paid directly to the selected provider.
Cortex connects with Xiaomi MiMo, DeepSeek, Anthropic, OpenAI, OpenRouter, Alibaba Qwen, Google Gemini, and InferenceHub. MCP server connections and extension and plugin management broaden its fit for projects with custom tooling. The main trade-off is that users must supply and fund their own model access, while desktop availability currently excludes macOS. Choose Cortex if indexed agent editing, local project context, and provider flexibility matter more than bundled AI usage. Consider an alternative if you need macOS support or prefer one subscription that includes model consumption.
