About JIT

JIT is an AI-powered code playground designed for rapid experimentation and development. It provides a versatile environment where users can chat with various AI models to generate, edit, and refine code in real-time. The platform is built around a "just-in-time" philosophy, offering a live preview feature that allows developers to see their changes instantly as they iterate. With support for multiple programming languages and built-in hosting, it bridges the gap between a simple chat interface and a full-fledged development environment, enabling creators to move from idea to live deployment without leaving the browser. The tool's feature set is extensive, including smart chatboxes, agent-based workflows, and robust versioning capabilities. Users can manage complex projects using snapshots and auto-deployment features, making it easy to transition from a prototype to a functional website. Collaboration is a core component, as the platform supports real-time editing and shareable links, allowing teams to build together or share their creations with a broader community. It also integrates various AI models, such as GLM 4.5, giving users the flexibility to choose the specific engine that best suits their coding task or complexity requirements. JIT is ideally suited for front-end developers, creative coders, and rapid prototypers who need to test ideas quickly without the overhead of setting up local environments. It serves roles ranging from hobbyists building 2D games and custom shaders to professionals at major tech companies who require advanced tools for internal dashboards or landing pages. The platform's transparent pricing model, which charges based on provider costs plus a small platform fee, makes it an attractive option for users who want to avoid the high monthly premiums of traditional "black box" AI services while maintaining full control over their usage. What distinguishes JIT from competitors is its commitment to transparency and community engagement. Unlike many proprietary coding assistants, JIT offers a pay-as-you-go credit system where users pay the actual provider cost, ensuring they are not overpaying for unused capacity. The public gallery encourages transparency by allowing users to fork and learn from existing projects, while the PRO tier offers the privacy and priority routing needed for commercial work. Its combination of live hosting, version control, and multi-model access makes it a comprehensive hub for modern AI-driven software creation.

JIT FAQs

How does the pricing for AI generations work on the platform?

The platform uses a transparent "provider cost" model where users pay exactly what the AI provider charges. On the Free plan, a 10% platform fee is added, while PRO users pay the provider cost with a 0% platform fee.

Can I keep my projects private?

Privacy depends on your subscription tier. Projects on the Free plan are public by default and shared to the community feed, whereas PRO users get private mode by default to keep their work confidential.

Does JIT offer hosting for the websites I build?

Yes, the platform includes free hosting and auto-deploy features. You can turn any workflow or code into a shareable website with a unique URL instantly from the playground interface.

What AI models are available within the playground?

JIT supports a variety of models, including high-end options like GLM 4.5. The multi-model interface allows you to experiment with different engines to find the best result for your specific code or logic.

Is there a limit to how much I can upload?

Free users are subject to limits on both file size and file count for their projects. PRO users benefit from no upload limits, though this is subject to reasonable fair-use and abuse prevention policies.
