Utilumo is a privacy-first browser toolbox for fast utility workflows. Writers, developers, and creators can clean text, inspect files, format data, and prepare content without sending private input to a server. Long source material often needs to be split before it fits comfortably into an AI prompt.
Questions
Are the chunk token counts exact?
No. They are local estimates. Exact counts depend on the model tokenizer.
Why add overlap between chunks?
Overlap repeats a small part of the previous chunk so the next chunk keeps nearby context when you paste it into an AI tool.
Does AI Text Chunker upload my text?
No. Text splitting and token estimation run locally in this browser tab.
Does Utilumo upload my input?
No. This tool is designed for local browser processing and does not send your input to a server.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
