hashchat is an app to chat, privacy levels data you share
HashChat offers a revolutionary approach to online communication by prioritizing privacy and anonymity. Designed for users who value freedom from traditional identity-based messaging, it allows individuals to connect via unique hashtags rather than personal data like phone numbers or email addresses. Starting every conversation at a 'Ghost Level' ensures total anonymity, with users controlling when and how to elevate trust levels. Its seamless, secure, and private semantic routing system makes it ideal for those seeking confidential interactions, whether for personal privacy, sensitive business discussions, or anonymous community engagement. With zero traceability—no device, IP, or contact info required—HashChat redefines what it means to communicate freely in the digital age, making it especially appealing to privacy-conscious users, developers, and communities seeking secure chat solutions.

Semantic search over your own Claude Code session history
Session-Indexer is an innovative open-source tool designed for developers and AI practitioners who utilize Claude Code sessions. It offers per-project semantic search capabilities by indexing session transcripts stored as JSONL files into a local SQLite database. By leveraging advanced embedding techniques with Ollama's bge-m3 models and fallback to FTS5 BM25, it ensures efficient retrieval of relevant past interactions. The tool automatically injects pertinent context at the start of each session, enabling users to seamlessly pick up where they left off or review key decisions made earlier. Unlike shared memory stores, Session-Indexer maintains complete project privacy, making it ideal for sensitive or proprietary work. Its simplicity—no deployment required and easy installation—combined with robust features, makes it a compelling choice for developers aiming to enhance their workflow with intelligent session management.
Pros
- Local, project-specific semantic search ensures data privacy
- Automatic context injection improves session continuity
- Uses state-of-the-art embeddings with fallback options for reliability
- Simple installation with no deployment needed
- Open source license (Apache 2.0) encourages customization
Cons
- Limited to Claude Code session transcripts, less versatile for other data types
- Requires familiarity with command-line setup and local database management
