Polyglot book from PGN in a couple of clicks (online + portable)

Hey, if you ever mess around with chess engines or just want your own opening book, this might be useful.

I made a simple tool that turns a PGN into a Polyglot .bin book. You upload your games (up to 25MB), decide how deep you want it to go, set a minimum number of times a move has to appear, pick White, Black or both, and it spits out a .bin file you can load into any engine or GUI that supports Polyglot.

No weird scoring magic or engine analysis — it just builds the book from the games you give it.

There’s an online version (no install) and a portable download if you prefer running it on your machine.

Worth a try if you’ve been looking for an easy way to make your own books:

Let me know if it works well for you or if something’s missing.

Biography: A Journey Through Knowledge, Mysticism, and Creation

Name: Alexander Lavin Occupation: Content Creator, Writer, Digital Producer, and Creative Technologist Alexander Lavin is a multidisciplinary creator driven by a lifelong fascination with the deeper structures of reality—where history, spirituality, art, and technology intersect. From an early age, he was drawn to ancient civilizations, sacred texts, and the hidden currents that shape human consciousness. This curiosity evolved into a sustained exploration of both canonical religious works—such as the Bible and the Quran—and esoteric and philosophical texts including The Kybalion and The Secret Doctrine, forming the foundation of his intellectual and spiritual worldview. As a writer and digital content creator, Alexander has dedicated himself to reviving forgotten knowledge and re-examining established narratives through a contemporary lens. His work spans blog essays, audiovisual projects, and long-form reflections that explore symbolism, metaphysics, frequency, memory, and the unseen forces influencing human experience. A recurring theme in his work is the dialogue between ancient wisdom and modern science, particularly in areas such as vibration, sound, consciousness, and the power of thought. In recent years, his creative path expanded into music production, where he composes and produces original works inspired by Christian, Gnostic, and Gregorian traditions, as well as experimental and free-form styles. These musical explorations are hosted on his channel TVLavin Music Lab, where sound becomes both prayer and investigation—an extension of his belief that music is a vehicle for memory, elevation, and spiritual resonance. Parallel to his artistic pursuits, Alexander has developed a deep and disciplined passion for programming, particularly in the realm of chess software and artificial intelligence. This interest culminated in the creation of Caissa Chess, a developing chess platform and experimental ecosystem that blends classical chess principles with modern engine analysis, human-centered design, and philosophical inquiry. Caissa Chess and its evolving variants reflect his broader vision: technology not as a cold instrument, but as a living dialogue between logic, creativity, and human intention. Based in Florida, Alexander continues to draw inspiration from both tangible landscapes and inner worlds. His work is guided by the conviction that knowledge is not merely accumulated, but remembered—and that ideas, dreams, and symbols leave measurable imprints on reality. Through writing, music, and software, he seeks to create works that invite reflection, awaken curiosity, and stand as quiet challenges to intellectual complacency.

Origins of the surname Lavin

The surname Lavin holds deep historical roots, with connections to several regions and noble families throughout Europe. The name likely stems from ancient Latin or Old Spanish origins, where it may have evolved from the name Levinus or the Latin word Lavare (to wash or cleanse). There are also theories that the Lavin surname has ties to the Levitical priesthood in ancient Israel, possibly connected to the tribe of Levi, the priestly caste of the Hebrew people. This theory holds special significance for families tracing Jewish ancestry that later converted or adopted Christian surnames. Heraldic Symbols and Coat of Arms: One of the most compelling aspects of the Lavin surname is its association with heraldic symbols. Heraldry was used in medieval times to identify families of noble standing, and the Lavin family is no exception. Coat of Arms Description: The Lavin coat of arms typically features a shield with blue and silver elements, symbolizing loyalty and purity, respectively. These colors are often accompanied by a lion rampant, representing courage and strength, a common motif in noble families' coats of arms. Symbolism: The lion on the Lavin coat of arms could be interpreted as a symbol of royalty and bravery, indicating that members of the Lavin family may have been involved in military or royal service in medieval times. The shield's colors might also suggest the family's loyalty to the crown or religious figures during significant historical events. The surname Lavin has roots in both Irish and French origins, with a few other variations depending on the region. 1-Irish Origin: The Lavin surname is most commonly associated with Ireland, particularly from County Roscommon. It is an Anglicized form of the Gaelic name Ó Láimhín, which means "descendant of the son of the prince." This surname is historically linked to Irish nobility, and its origins can be traced back to the early Gaelic kingdoms. 2-French Origin: The name Lavin may also have French roots, particularly as an occupational name derived from the French term "La Vigne," meaning "the vineyard." This would suggest that the name was originally given to people who owned or worked in vineyards, particularly in regions like Gironde and Loire. Some of these French Lavins were Huguenots who fled to England during the religious persecutions of the 17th century. 3-Other Origins: In Cornwall, England, Lavin might be linked to an Anglo-Norman personal name. Additionally, in Spain, the surname Lavín is a habitational name from the Cantabria region. The Lavin surname has appeared in various records across the United States, the UK, and other countries, often linked to significant historical migrations, such as the Irish Potato Famine
