Small tools for private work

Local Toolkit is a free early-access workspace for short texts and CSV price lists. Summarize notes, translate a message, rewrite a draft, extract action items, clean text or compare two tables. Review the result and take it with you as text or CSV.

What this version does

AI tools accept up to 2,000 characters. Text cleanup supports up to 20,000 characters. CSV files can be up to 5 MB each, with 20,000 rows and 40 columns. Text import supports UTF-8 .txt and .md files, within the selected tool’s character limit. There is no PDF, OCR, audio or image generation. Generated content is not executed.

Local models are not infallible

AI results may omit or invent details. Check the source before relying on names, amounts, translations or deadlines. Extraction validates the response format, not its factual accuracy. CSV arithmetic uses deterministic fixed-point calculations; AI only suggests the filter you review. Compatible desktop hardware with WebGPU is required for Bonsai. Mobile users can use text cleanup and manual CSV comparison.
