Matasoft Unveils Browser‑Based AI Spreadsheet Sandbox for Safe, No‑Install Testing

ZAGREB, Croatia - Feb. 8, 2026 - PRLog -- Matasoft today announced the availability of a browser‑based portal for its (Un)Perplexed Spready application, a next‑generation spreadsheet that embeds AI models directly into formulas so users can extract, classify, enrich and transform data using natural‑language prompts inside cells. The new online environment lets businesses evaluate AI‑powered spreadsheets without installing software, configuring infrastructure or wiring up large language models (LLMs), web search and custom tools themselves.

(Un)Perplexed Spready is designed for teams whose day‑to‑day work happens in spreadsheets but who need more than traditional formulas can offer, especially for tasks like product taxonomy mapping, text extraction, address standardisation and intelligent classification. Instead of copy‑pasting from chatbots, users work with formulas embedding LLM prompt, which take ranges and prompt cells as inputs and return AI‑generated results directly into the grid.

Online portal: AI spreadsheet in a browser

The new web portal exposes (Un)Perplexed Spready as a hosted application at spready.matasoft.hr, with all AI components pre‑configured, including Ollama or Ollama Cloud models, Open WebUI as an API layer, SearXNG meta‑search and Matasoft's own web search and web reader tools. From the first screen, users can open demo workbooks or upload their own files and immediately start experimenting with AI formulas in a familiar spreadsheet interface.

The portal offers two modes of access: an Anonymous – Free (4 hours) tier, which allows anyone to start a time‑limited session without logging in, and a Licensed – Unlimited tier intended for regular or production‑style work without time limits.

40+ AI‑enabled demo spreadsheets

To shorten the learning curve, the online portal ships with a library of more than 40 demo XLSX files that illustrate concrete, real‑world use cases. Example workbooks include product catalog classification with taxonomy lists, webinar invite processing, school research and various enrichment and labeling scenarios.

Each demo contains pre‑defined AI formulas, example input columns and output columns that show exactly how prompts, ranges and taxonomies are combined to solve tasks such as taxonomy mapping, entity extraction, web‑based enrichment, annotation and multi‑label classification.
