Chatlog is a local-first chat history viewer and indexing tool designed to organize and search personal messaging exports. It functions as a static web application that transforms unstructured chat data into a standardized format using schema-based parsing rules.
The system operates entirely on the client side, building a searchable message index within the browser to enable fast retrieval of conversations. By storing data directly on the user device, the tool allows for private message analysis and archiving without the use of a central server.
The application is delivered as a bundle of pre-compiled static assets, allowing it to be hosted on simple file servers or run locally.
