ThinkThread empowers developers to add persistent memory to ChatGPT-driven applications. It encodes each exchange using Sentence Transformers and stores embeddings in popular vector stores. On each new user input, ThinkThread performs semantic search to retrieve the most relevant past messages and injects them as context into the prompt. This process ensures continuity, reduces prompt engineering effort, and allows bots to remember long-term details such as user preferences, transaction history, or project-specific information.

UniChat serves as a unified interface for interacting with various AI language models and chat services, enabling users to conduct conversations with multiple providers from one desktop application. It integrates online APIs—such as OpenAI GPT-3, GPT-4, Anthropic Claude, and Google PaLM—alongside local models like GPT4All or LLaMA. The client supports features such as conversation history storage, exportable chat logs, customizable prompt templates, file upload for context, and theming options. A plugin system allows developers and the community to add new capabilities, connectors, or UI enhancements. By managing API keys centrally and providing offline mode for local models, UniChat gives users complete control over their AI interactions, privacy, and costs.
