  "account": "This is a submission for the Hacktoberfest Open-Source AI Challenge Week 3: Slow and Steady. The project, MediaMend, is an AI assistant designed to help users manage their media collection effectively. MediaMend addresses the common issue of having more recorded media than one can review, dealing with blurry photos, black video frames, silent recordings, empty files, and duplicates.\n\nThe tool works by scanning a folder on the user's computer and does not upload any data. Users are then presented with a short queue of flagged files, each accompanied by a reason and confidence level. They can choose to move the files to the Bin, or mark them as Approved, in which case they are moved out of the scanned folder but not deleted. The user has options to Restore, Archive, or Delete permanently from the Bin, with permanent deletion requiring a separate confirmation.\n\nThe tool uses several deterministic checks for issues: OpenCV Laplacian variance for blur detection, resolution checks, sampled video frames for blank frames, FFmpeg decoding for silence, and SHA-256 for exact duplicate detection. It also utilizes a local open-weight vision-language model, which can be run via Ollama, to make judgments on flagged photos. This model answers the question of whether an imperfect image could still be worth keeping, and returns structured JSON for validation. If the model is unavailable or provides an incorrect answer, it informs the user instead of providing a fake result.\n\nA safety layer records the original path, size, and SHA-256 of each file in a manifest, and verifies the checksum afterwards. This ensures that no file is moved or deleted without verification. The tool is built using Python, Streamlit, OpenCV, FFmpeg, and the Ollama model with a specific vision-language model.\n\nTechnical measurements and AI opinions are stored separately from the actual actions taken by the tool, so the AI's guess never overwrites measured evidence. The results of testing on labeled files are provided, with metrics for precision and recall for blur detection, false positives on must-keep files (both from rules and AI), and success rates for checksum verification during restoration. The scan time for all files and the time taken by the AI per photo on a specific hardware setup are also provided.\n\nOne limitation of the tool is that it cannot judge creative value perfectly, and deleting files from the Bin may not securely erase every copy on SSDs, backups, or synced folders. The author also notes that the thresholds used are starting points and may not be universal. The project emphasizes privacy, control, cost-effectiveness, transparency, and reproducibility. The code, prompts, thresholds, and test set are all publicly available.",
