Abstract

The widespread reliance on cloud-based large language model (LLM) services has raised significant concerns around user privacy, internet dependency, and workflow fragmentation across disparate tools. This paper presents the design, implementation, and evaluation of UNplugged.ai, a standalone offline-first multi-modal AI workbench implemented in Streamlit that orchestrates local model inference through the Ollama runtime. The system provides six distinct interaction modalities within a unified interface: free-form conversational chat, document question-answering for PDF and DOCX formats, raw text ingestion, image-grounded prompting, and speech-enabled voice interaction. All document processing and inference operations are executed locally on the host machine, ensuring that sensitive content remains on-device throughout the interaction lifecycle. Additionally, the platform incorporates a serialized scikit-learn emotion classification module that computes real-time sentiment predictions and probability distributions over recognized emotion classes for both user prompts and model responses, rendering the results as interactive Altair bar charts. A direct context-stuffing strategy is employed for document grounding, eliminating the dependency on vector databases or embedding infrastructure. Experimental analysis demonstrates the platform's viability as a privacy-preserving alternative to cloud-hosted AI productivity tools, while also identifying specific limitations in voice input, image prompting, and context scaling. The paper discusses system architecture, prompt construction strategies, modality-specific pipelines, performance considerations, known limitations, and directions for future enhancement.

Full Article/Conclusion

This paper has presented UNplugged.ai, an offline-first multi-modal AI workbench that consolidates six interaction modalities within a single Streamlit application backed by a locally-running Ollama inference daemon. The system demonstrates the feasibility of constructing privacy-preserving, locally-executable AI productivity tools using the Python open-source ecosystem without dependence on cloud inference infrastructure or vector database deployments. The direct context-stuffing approach to document grounding eliminates retrieval pipeline complexity at the cost of context window scalability, a tradeoff appropriate for moderate-length documents on hardware with sufficient memory bandwidth to serve the selected model efficiently. Limitations identified in the current implementation define a concrete roadmap for future enhancement. Immediate priorities include replacement of the Google speech recognition backend with a locally-executable alternative such as Whisper [18] or Vosk, correction of the PIL import error in the image tab, and implementation of a configurable chunking and retrieval pipeline supporting longer document contexts. Longer-term directions include structured multimodal image attachment support compatible with vision-capable Ollama models, persistent cross-session conversation storage, and a formal user study evaluating the system's usability and perceived trustworthiness relative to cloud-hosted alternative workflows.
