Contract AI

Inspiration

In today's fast-paced world, the process of drafting and negotiating contracts remains a significant bottleneck for individuals, startups, and even large enterprises. It's a meticulous, time-consuming, and often daunting task, fraught with complex legal jargon and a high risk of costly human error. We were inspired to tackle this universal challenge head-on. Our mission is to democratize legal document creation, transforming it from a source of friction into a seamless, intelligent, and reliable experience for everyone, regardless of their legal expertise.

What it does

ContractAI.online is an intelligent, AI-powered platform designed to revolutionize the contract lifecycle.

Here’s how it works: A user begins by uploading an existing contract template (in PDF or Word format). They are then taken to our intuitive chat interface, where they can instruct an AI agent, powered by OpenAI's GPT-4.1, to make modifications. These instructions can range from simple textual corrections to complex requests, such as adding entirely new sections. The AI doesn't just add text; it analyzes the context of the entire document to generate content that is coherent, relevant, and consistent with the existing legal framework of the contract.

One of our standout features is the real-time visualization canvas. As the user interacts with the AI agent, they can see the proposed changes reflected live on the document. This transparent, side-by-side view demystifies the editing process and gives the user complete control and confidence in the outcome.

Once the contract is perfected, it can be exported as a polished PDF or Word document. Furthermore, the final version can be tagged and saved as a new, dynamic template in the user's private library, ready for future use.

How we built it

ContractAI.online stands as a testament to the power of modern development tools and a new paradigm of software creation.

The entire application was built using Bolt.New, and we are incredibly proud that it was developed exclusively through prompts. No manual code was written or modified in the codebase generated by Bolt.New. This prompt-driven development process allowed us to build a complex, feature-rich application at unprecedented speed.

Our technology stack also integrates a suite of powerful tools to ensure robustness and scalability: Bolt.new n8n: For workflow automation and backend process orchestration. Supabase: As our backend, providing a secure and scalable database and authentication. Lingo.dev: For managing our localization efforts, enabling us to build a globally-ready application from day one.

The application currently supports English, Spanish, Turkish, and French, but its architecture is primed to scale to over 80 languages in future iterations.

Key Features & Innovations

Real-Time Visualization Canvas: Instantly see AI-driven changes on your document as you type, ensuring full transparency and control. Dynamic Templating & Exporting: Save finalized documents as new, reusable templates and export them in standard PDF and Word formats. Built-for-Scale Multilingual Support: Architected from the ground up to support a global user base, starting with four languages and ready for 80+. 100% Prompt-Driven Development: A showcase of the future of software development, built entirely on Bolt.New without a single line of manual code.

What we learned

This hackathon provided the perfect crucible to forge our idea into a functional, impactful product. The time-bound, high-energy environment compelled us to fully embrace next-generation tools and validate our core hypothesis: that sophisticated, user-centric applications can be brought to life without traditional coding, significantly reducing development time and complexity. This journey has not only been about building a product but about pushing the boundaries of what we thought was possible in rapid application development.

What's next for Contract AI

We are just getting started. Our immediate roadmap is focused on evolving from monolithic templates to a modular, "Lego-like" system. Soon, users will be able to build entirely new, bespoke contracts from scratch by assembling them from a library of pre-vetted, individual clauses and sections. This will further accelerate the creation of highly customized legal documents. Alongside this, we will be activating our infrastructure to roll out support for over 80 languages, making ContractAI.online a truly global solution. We believe ContractAI.online is not just a tool, but the future of how we interact with legal documents: making it faster, smarter, and accessible to all.
