We are proud to announce the opening of our new subsidiary, BitStone (Schweiz) AG.
This milestone marks our long-term commitment to the Swiss market and our ambition to be closer to our clients, offering both local presence and trusted technology expertise.
Foundations
Our story began almost two decades ago, not in a boardroom or on a strategy deck, but in the classrooms of the Technical University of Cluj-Napoca, where two computer enthusiasts discovered a shared passion for using technology to solve real-world challenges.
What started as a series of freelance projects soon grew into something bigger. In 2006, we founded BitStone, determined to transform our curiosity and skills into lasting impact.
Over the years, our small team evolved into a community of more than 100 talented professionals, all driven by the same mission: to craft high-quality software solutions that empower companies around the world.
Legal Invoice Reviews Completed in Seconds
AI agents using large language models have demonstrated the ability to review legal invoices with over 90% accuracy, completing the task in just 3-4 seconds per document. A recent study found that these systems consistently flagged billing inconsistencies and extracted key information with a high degree of reliability. By significantly reducing the time and cost required for invoice audits, AI-supported review workflows can enhance transparency, scalability, and operational efficiency, especially in high-volume legal environments.
AI Agent Reviews Contracts 77× Faster with Consistent Accuracy
A recent study evaluated how an AI agent performed in contract review tasks. The AI system completed document reviews in under a minute, up to 77 times faster than manual review, while maintaining a high degree of consistency with established standards. Rather than replacing legal judgment, the agent served as a powerful assistant: surfacing key terms, identifying relevant clauses, and reducing bottlenecks in high-volume contract workflows. For legal teams, this translates to faster turnaround, increased review efficiency, and fewer hours lost to repetitive review work.
How Custom AI RAG Agents Help Legal Teams
Document Retrieval & Natural-Language Question Answering
Legal teams often spend significant time navigating contracts, compliance manuals, and case files to find the right information. A custom AI agent with RAG allows them to ask questions in natural language and receive accurate, source-linked answers, retrieved directly from their internal documentation, knowledge bases, or case repositories. There's no need to recall precise file names, clause wording, or document versions: the system understands context and delivers relevant content instantly.
Efficient Contract Review & Clause Comparison
RAG agents can scan entire contract libraries to identify clauses, compare versions, or highlight deviations from standard terms. This allows legal ops and in-house counsel to quickly flag non-compliant language, unusual risk points, or negotiation gaps, without the need of a line-by-line review. These agents can also be trained to follow company-specific legal playbooks or template logic.
Fast, Scalable Legal Invoice Auditing
For firms handling high volumes of legal invoices, AI agents can analyze line items, flag inconsistencies, and match billed tasks to contract terms or matter budgets, all in seconds. This ensures better billing oversight, reduces manual audits, and cuts audit turnaround from days to minutes.
Accelerated Legal Research
RAG agents can connect to trusted legal content (e.g., internal memos, prior case summaries, or licensed data from platforms like Westlaw or LexisNexis) to find relevant precedents, citations, and legal arguments, without the overhead of sifting through dozens of sources manually. This supports faster motion drafting and legal strategy preparation.
Internal Knowledge Access & Compliance Guidance
Legal teams often hold the answers, but others in the organization don’t know where to look. A RAG agent trained on internal policies and legal guidelines can act as an always-on assistant, providing compliance answers or usage rules to HR, finance, or sales, without exposing sensitive data externally.
Custom AI Agents That Ensure Data Privacy and Security
Legal teams often hold the answers, but others in the organization don’t know where to look. A RAG agent trained on internal policies and legal guidelines can act as an always-on assistant, providing compliance answers or usage rules to HR, finance, or sales, without exposing sensitive data externally.
Private by Design
Custom RAG agents are deployed fully within your organization’s secure infrastructure, whether on-premises or in a private cloud environment.
They operate without reliance on external APIs, ensuring sensitive documents and client data remain fully contained and never leave your controlled systems.
Audit-Ready and Compliant
Every query, action, and document reference is logged, creating a full audit trail that supports chain of custody requirements and internal review processes. Ideal for regulated environments or firms managing sensitive case data.
Answers You Can Trust
All responses are generated exclusively from your organization’s verified documents, including contracts, internal guidelines, and case materials, with clear source citations provided. This ensures every answer is grounded, relevant, and fully traceable, eliminating the risk of unsupported or speculative outputs.
Human Controls
Custom workflows can include built-in approval steps, legal checkpoints, or review gates, ensuring AI-assisted work never replaces legal oversight, but instead enhances it with speed and clarity.
What This Means for Legal Teams
Custom AI RAG agents offer legal teams a way to work faster, reduce manual overhead, and stay fully in control of sensitive information. Whether you're reviewing contracts, auditing invoices, or answering complex compliance questions, these agents turn hours of work into seconds, without compromising security or precision. For legal organizations aiming to stay competitive, the question is no longer whether to adopt AI, but how soon it can be implemented to drive measurable impact.
