Computational reproducibility of scientific results, that is, the execution of a computational experiment (e.g., a script) using its original settings (data, code, etc.), should always be possible. However, reproducibility has become a significant challenge, as researchers often face difficulties in accurately replicating experiments due to inconsistencies in documentation, setup configurations, and missing data. This lack of reproducibility may undermine the credibility of scientific results. To address this issue, we propose a conversational, text-based tool that allows researchers to easily reproduce computational experiments (theirs or from others) and package them in a single file that can be re-executed with just a double click on any computer, requiring the installation of a single widely-used software. Researchers interact with the platform in natural language, which our tool processes to automatically create a computational environment able to execute the provided experiment/code. We conducted two studies to evaluate our proposal. In the first study, we gathered qualitative data by executing 18 experiments from the literature. Although in some cases it was not possible to execute the experiment, in most instances, it was necessary to have little or even no interaction for the tool to reproduce the results. We also conducted a user study comparing our tool with an enterprise-level one. During this study, we measured the usability of both tools using the System Usability Scale (SUS) and participants' workload using the NASA Task Load Index (TLX). The results show a statistically significant difference between both tools in favor of our proposal, demonstrating that the usability and workload of our tool are superior to the current state of the art.
