HomeMemory {Memo}

说明与用途

HomeMemory 是一款个人记忆助手，用户可以拍照记录物品并添加备注，然后用自然语言查询。它使用本地 Gemma 4 模型和 MongoDB Atlas 进行存储和检索，显著降低搜索时间并提升可靠性，特别适合家庭使用。

问题

Families forget small but important items and dates, such as where a spare key is or when a medicine expires.

结果

The system achieved a top‑1 retrieval accuracy of 78% on 10 real items, reducing retrieval time from 10‑15 minutes to 2‑3 minutes.

工作流

• Take or upload a photo of an item
• Add a short note about its location
• Gemma 4 (via Ollama) processes the photo and outputs structured JSON
• EmbeddingGemma creates a vector for the memory
• MongoDB Atlas Vector Search stores and retrieves memories
• User queries in English/Urdu; system returns the photo and note
• Optional confirm‑and‑edit before saving
• Threshold controls whether a match is returned or "not found"

证据

Gemma 4 runs locally through Ollama. It reads each photo and returns structured JSON (category, item, description, readable text, expiry date) and writes the final answers.

I built HomeMemory by working with Claude in a chat window, then running and testing everything on my own laptop.
