5ire

5ire is an open-source AI client designed to make large language models easy to use, even for beginners. It parses and vectorizes documents in formats such as docx, xlsx, pptx, pdf, txt, and csv, and builds a local knowledge base for retrieval-augmented generation. Other features include usage analytics that track API cost, a prompt library that supports variables, conversation bookmarks, and keyword search across all chats. The app is free to download, while large model access runs on a pay-as-you-go API. It suits people who want a private, local way to work with their own files and keep an eye on spending.

- Import documents and build a local knowledge base

- Create and organize reusable prompts with variables

- Search across all conversations by keyword

- Track API usage and cost in the analytics panel

- Knowledge workers who handle many documents

- Educators building private material libraries

- Researchers who want local retrieval over their files

The app itself is free, but large model access is pay-as-you-go, so costs scale with how much you use it. Initial setup and indexing take time, especially with large document sets, and local performance depends on your machine. Because it is an open-source project, check how actively it is maintained before you build a workflow around it. When quality matters, export a small draft first to confirm the result before producing the final file. Generated suggestions are for reference only, so verify anything that affects professional judgment or important data. Run one full task end to end first, then expand once you are comfortable with the workflow and the result quality.
