Sunchay is a personal knowledge management tool designed to help users save various types of content and retrieve it effortlessly. It serves as a centralized memory bank where users can store notes, links, files, media, and messages without getting overwhelmed by clutter.

The product allows users to save content from multiple sources including WhatsApp messages via forwarding, web content through a browser extension, and various file types like PDFs, images, videos, audio, voice memos, documents, emails, screenshots, web archives, highlights, code snippets, spreadsheets, notes, articles, and bookmarks. It features semantic search that enables finding items by meaning rather than exact keywords, and includes Ask SunchayAlpha which provides synthesized answers with sources from saved content. The system automatically extracts metadata and connects related ideas without requiring manual organization.

Sunchay works by capturing content in the moment through integrations like WhatsApp forwarding and browser extensions. When users need to find something, they can use semantic search or ask questions naturally, and the system pulls together all relevant saved items around a topic, decision, project, or idea.

The benefits include having a calm, organized space for all saved knowledge, quick retrieval of information, and privacy assurance. Use cases involve managing research for projects like buying a car, planning trips, handling work projects, learning new skills, and developing startup ideas by unifying scattered notes and references.

The target users are individuals who need to manage personal knowledge and information across various formats. It integrates with WhatsApp and web browsers via extensions, and emphasizes privacy with no ads, tracking, or data mining, using HTTPS encryption and AES-256 security.
