Start your prime number research today. Try every feature free for one day. Use the trial on your own PC to see how the app works and how fast it runs. MCP support lets you connect to AI clients such as Codex. Through conversation, you can request prime dataset generation and verification, then use the results for analysis and visualization. Riragon Prime Generator is a Windows application that generates and saves prime number lists for the numeric intervals you choose, directly on your own PC. In a benchmark run, the app generated and saved all 4,118,054,813 primes from 2 through 100 billion (10¹¹) in BIN format in approximately 5 minutes 25 seconds. The resulting data occupied approximately 30.68 GiB. Including file integrity verification, the run finished in approximately 8 minutes 5 seconds. The maximum allowed start and end values are 10¹⁸ (one quintillion). The result for the interval up to 100 billion (10¹¹) is a benchmark example showing processing speed. Processing time and storage requirements depend on the interval you select. Benchmark system: Windows 11 Pro (64-bit), Intel Core i9-9900K, 64 GB RAM, and a Samsung 970 series NVMe SSD. Power plan: Eco Balanced - Office (custom settings). App version 1.0.1, 16 threads, BIN output (unsigned integers, 8 bytes each), and no file splitting. These timings use file integrity verification; they do not include full independent verification of the prime sequence. Processing time varies with PC performance, power settings, the selected interval, output format, and verification method. Choose a start value, an end value, an output folder, and a format, then start generation. Prepare data for research and learning without searching for prime lists online or downloading large datasets. Prime generation and verification run locally and do not require an internet connection. Features to support your workflow: - Export to TXT, CSV, TSV, JSON, or BIN for use in your own analysis programs and visualization tools. - Estimate output size and file count before generation, and track progress while the job runs. - Resume interrupted jobs and split output files by a specified size. - Check file integrity or choose full independent verification using a separate implementation. - Automatically save generation settings, verification results, and a reproduction command in a report, so you can repeat experiments with the same settings. - Save and load settings, and switch between Japanese and English. CLI, JSON API, and MCP support let you automate tasks with scripts or request generation and verification from MCP clients such as Codex. Connection instructions and configuration examples are available inside the app. Intervals near 10¹⁸ have also been checked against results from independent calculations. Select the interval you need for your research or experiments. Explore prime patterns, gaps, and distributions, or test your own programs with large prime datasets. Start with data generated on your own PC.
