How do I search and reference documents in Chunk?

To search and reference documents in Chunk, simply start by uploading any files you want into Chunk’s knowledge base. Once your files are uploaded, you can begin referencing your documents in several ways:

Ask Chunk directly: If you're looking for something specific, phrase your query with as much precision as possible. For example, if you’re searching for a document with details about a project named 'Atlas', you could ask, “What is the status update on Project Atlas mentioned in the March reports?” Chunk matches keywords used in your question with content from your documents to find the most relevant information.

Utilize tags: You can add tags to your documents for easier searching. Using tags acts like filters, which can help you include, exclude, or compare documents. For instance, if you have tags named 'Q1' and 'Financials', you could apply these to filter results to that specific intersection.

Documents: Here, you can manage your uploaded files, add tags, and CHUNK your documents to organize your content optimally, depending on the level of detail required.

Use the Related Documents sidebar: On the iPad and Mac versions of Chunk, the sidebar will show documents related to your current chat conversation or note, allowing you to quickly reference pertinent files.

How can I ensure accurate and precise AI responses with Chunk?

To ensure accurate and precise AI responses with Chunk, follow these tips:

- Be precise with your questions, matching the language of your documents when possible.

- Use tags to categorize and filter, aiding Chunk in narrowing down the search to relevant documents.

- Utilize Chunk’s CHUNKing feature to break down larger documents into manageable 'chunks' for more focused AI analysis. Use the default, Medium for most documents and notes is usually the best choice. However for larger files i.e. Books, code, or documents with multiple pages of information we suggest using large chunks.

- Regularly update and refine your tags to maintain an organized knowledge base.
