Mark uses Whisper Tiny or Base models loaded directly onto your smartphone (supporting English only). This allows audio capture and classification to be done entirely on-device, meaning you can speak to save transactions without any internet connection.

Whisper transcribes speech in up to 99 languages. For transaction amount parsing and classification, Mark features custom-built spoken-number structures supporting 13 core languages (including English, Spanish, French, German, Portuguese, Hindi, Bengali, Marathi, Tamil, Telugu, Mandarin, and Japanese). Note that local (on-device) Whisper only supports English; all other languages are supported via paid tiers (Premium subscription, or Gemini LLM / Groq API keys via BYOK).

Mark is a local-first application. Your financial records are saved on your device inside an encrypted SQLite database using Drift ORM. This data does not leave your phone unless you explicitly configure the Google Drive cloud sync options.

Mark reaches an accuracy rate of 95%+ by combining advanced regex-based token parsing with intelligent LLM fallback (using models like Gemini or Groq). It extracts transaction quantities and categories instantly, routing complex natural language phrasing to state-of-the-art LLMs to guarantee high precision even for complex expressions.

Lite users can provide their own Gemini or Groq API keys (BYOK) under Settings to access advanced cloud-based LLM features like real-time text parsing, expense insights, and smart categorization without subscribing to the Premium plan.

The dashboard contains metric cards dedicated to tracking Borrowed and Lent balances. You can log borrowed funds, assign due dates, and Mark will automatically flag pending debts with urgent status badges or upcoming EMI reminders.

Premium users can connect their Google account under settings to authorize Google Drive sync. You can manually trigger uploads, view timestamps of recent backups, or restore past recovery points. Note: restoring data will replace your current local database (last write wins) and require a quick app restart to load.
