About Compare AI: Diff & Merge
Compare AI: Diff & Merge is a fast, 100% on-device comparison workstation for software engineers, sysadmins, analysts, and editors. Inspect and compare source code, JSON trees, configuration files, tabular data, PDF documents, and natural-language text, with no cloud uploads, no API keys, and complete privacy.
All diff parsing, tokenization, and structural analysis run on your device, so credentials, proprietary code, and private documents never leave your phone.
KEY COMPARISON ENGINES
• SOURCE CODE DIFF: Compare Dart, Python, JavaScript, Kotlin, C++, Rust, and Swift files with line-by-line diff, inline token highlighting, and additions/deletions statistics.
• JSON TREE DIFF: Structural inspection that detects modified keys, nested object changes, array reordering, and type changes.
• CONFIG & ENVIRONMENT DIFF: Compare Nginx configs, .env files, YAML, TOML, and INI to catch configuration drift and critical changes before you ship.
• CSV & TABULAR DIFF: Side-by-side cell diffing across CSV and TSV data with added rows, removed columns, and changed values.
• XML DIFF: Node-by-node comparison for XML documents, SVG, Android manifests, and plist files.
• PDF LAB: Compare PDF page text on-device to spot version changes and clause edits.
• TEXT & ORTHOGRAPHY STUDIO: Deep text comparison with an on-device Turkish orthography (imla) assistant.
• ON-DEVICE CHANGE SUMMARY: Plain-language summaries of what changed and which changes look critical, generated locally by embedded rules and optional downloadable local models.
• EXPORT: Generate color-coded Word (.docx), PDF, and plain-text reports from your history vault.
PRIVACY BY DESIGN
• 100% offline processing: files and inputs are never sent to remote servers or third-party AI APIs.
• No background services: the app works only while you use it.
• Safe file picking: no broad storage permissions are requested.
• Built for Android 15 and 16 devices, including 16 KB page size support.
