In a historic move towards using technology in law enforcement, Microsoft Chairman and CEO Satya Nadella announced the state-wide implementation of an AI-based crime-solving solution named MahaCrimeOS AI for the state police. This solution is set to go live at all 1,100 police stations in the state, making it a leader among other states that implement AI-based law enforcement. Launched on 12th December 2025, this is a result of a deep collaboration between Microsoft, the state of Maharashtra, and their AI-based special law enforcement agency for the state of Maharashtra named MARVEL.
Background: MARVEL and AI in Policing
- MARVEL (Maharashtra Research and Vigilance for Enhanced Law Enforcement) is a government-owned AI initiative, established in 2024 to modernise policing in Maharashtra.
- Objectives: Strengthen police intelligence, improve crime prediction, and modernise investigation methods. Maharashtra became the first state in India to create an independent AI body for law enforcement.
- MahaCrimeOS AI builds on the pilot project in Nagpur Rural, operational in 25 police stations since April 2025.
How MahaCrimeOS AI Works
- Multimodal Data Ingestion: Handles complaints in PDFs, audio, handwritten notes, or images, and extracts critical information in any language, including Marathi.
- Automated Investigation Planning: Generates detailed investigation workflows following Maharashtra Police protocols and judicial guidelines.
- Data Analysis and Intelligence: Analyses telecom data, social media activity, and open-source intelligence to identify suspects and interlinkages.
- Case Management: Maintains time-stamped case diaries and tracks active cases, updates, and pending actions.
- Cybercrime Efficiency: Reduces dependency on senior officer approvals, enabling faster decision-making in complex cases like cybercrime, financial fraud, and crimes against women.
From Pilot Project to Statewide Rollout
- MahaCrimeOS AI was initially introduced as a pilot project in Nagpur Rural in April 2025, where it was deployed across 23 police stations, including cybercrime police stations.
- During the pilot phase, 127 police officers were trained, and the platform was used in 261 cases.
- Encouraged by its success, the Maharashtra government decided to expand the system to all 1,100 police stations across the state, marking one of the largest AI deployments in policing anywhere in India.
Judicial Compliance and Case Documentation
- Another critical feature of MahaCrimeOS AI is its ability to prepare time-stamped, date-wise case diaries suitable for court submission.
- The system integrates best practices from High Court and Supreme Court rulings, reducing procedural errors and strengthening prosecution quality.
- Earlier, investigating officers often had to wait for senior officials to review files and provide instructions in complex cases.
Key Takeaways
- MahaCrimeOS AI is an AI-powered crime investigation platform launched for Maharashtra Police.
- Announced by Microsoft CEO Satya Nadella in December 2025.
- Rolled out across all 1,100 police stations in Maharashtra.
- Developed under MARVEL, India’s first state-level AI body for law enforcement (set up in 2024).
- Uses multimodal AI to process FIRs, audio, images, handwritten notes, and digital data in multiple languages, including Marathi.
