Show HN: Unified multimodal memory framework, without embeddings

Hi HN,

We’ve been building memU(https://github.com/NevaMind-AI/memU), an open-source, general-purpose memory framework for AI agents. It supports dual-mode retrieval: classic RAG and LLM-based direct file reading.

Most multimodal memory systems either embed everything into vectors or treat non-text data as attachments. These work, but at scale it becomes hard to explain why certain context was retrieved and what evidence it relies on.

memU takes a different approach: since models reason in language, multimodal memory should converge into structured, queryable text, while remaining fully traceable to original data.

---

## Three-Layer Architecture

- Resource Layer Stores raw multimodal data as ground truth. All higher-level memory remains traceable to this layer.

- Memory Item Layer Extracts atomic facts from raw data and stores them as natural-language statements. Embeddings are optional and used only for acceleration.

- Memory Category Layer Aggregates items into readable, theme-based memory files (e.g. user preferences, work logs). Frequently accessed topics stay active; low-usage content is demoted to balance speed and coverage.

---

## Memorization Bottom-up and asynchronous. Data flows from resources → items → category files without manual schemas. When capacity is reached, recently relevant memories replace the least used ones.

## Retrieval Top-down. memU searches category files first, then items, and only falls back to raw data if needed. At the item layer, it combines BM25 + embeddings to balance exact matching and semantic recall, avoiding embedding-only imprecision.

Dual-mode retrieval lets applications choose between: - low-latency embedding search, or - LLM-based direct reading of memory files.

## Evolution Memory structure adapts automatically based on real usage: - Frequently accessed memories remain at the Category layer - Memories retrieved from raw data are promoted upward and linked - Organization evolves from usage patterns, not predefined rules

Goal: keep relevant memories retrievable at the Category layer and minimize latency over time.

---

## A Unified Multimodal Memory Pipeline memU is a text-centered multimodal memory system. Multimodal inputs are progressively converted into interpretable text memory, while staying traceable to original data. This provides stable, high-level context for reasoning, with detailed evidence available when needed—inside a memory structure that evolves through real-world use.

Show HN: RepoReaper – AST-aware, JIT-loading code audit agent (Python/AsyncIO)

OP here. I built RepoReaper to solve code context fragmentation in RAG.

Unlike standard chat-with-repo tools, it simulates a senior engineer's workflow: it parses Python AST for logic-aware chunking, uses a ReAct loop to JIT-fetch missing file dependencies from GitHub, and employs hybrid search (BM25+Vector). It also generates Mermaid diagrams for architecture visualization. The backend is fully async and persists state via ChromaDB.

Show HN: Tylax – A bidirectional LaTeX to Typst converter in Rust

Hi HN, author here.

I built Tylax because I wanted to migrate my old LaTeX papers to Typst but found existing regex-based scripts too fragile for nested environments.

Tylax parses LaTeX into an AST (using mitex-parser) and converts it to Typst code. It supports: - Full document structure (not just math snippets) - Complex math (matrices, integrals) - Experimental TikZ -> CeTZ graphics conversion - Runs in browser via WASM

Repo: https://github.com/scipenai/tylax Web Demo: https://convert.silkyai.cn/

Happy to answer any questions!

Show HN: A RAM-only, end-to-end encrypted P2P terminal chat in Python

Hi HN,

This is cmd-chat, a Python terminal chat app designed around a few constraints:

- No central servers - No message or key persistence - No plaintext credentials ever sent over the network

Authentication uses *SRP*, and messages are encrypted after key exchange. All data lives in memory only and disappears when the process exits.

This was partly a learning project and partly an experiment in building a “minimum-trust” chat system using standard cryptographic primitives.

Curious to hear thoughts on the threat model, crypto choices, and overall design.
