Where it falls short
- Long reports drift on smaller models
- Citations need a human check
Cloud & apps
Cloud assistants hold more of a long report in one chat and edit more cleanly.

Our take
Keep a confidential report local. Use a cloud notebook when the sources are already shareable.
Choose local if…
- The report is unpublished
- You already have the notes
Choose cloud if…
- You want quotes from many PDFs
- The draft is very long
How to do it in 3 steps
- Open the model page and pick any app under Runs in, for example AnythingLLM, GPT4All or Jan. Each app page links to that maker's own guide.
- Open the Qwen3.5 27B page and check the traffic light for a few kinds of computer.
- Follow that official guide. This site does not add its own install steps.
Questions
- Does this upload my files?
- The local tools on this page don't upload your files. The cloud options in the comparison do.
- What does it cost?
- Most options are free. A few apps are a one-time purchase, and a few models need a computer with more memory.
- What if it will not fit?
- Use Check my computer, or turn on the lighter memory filters. A red light on the model page means the file is too big.
