Local AI

- Offline, including on a plane
Where it falls short
- Small models miss subtle grammar
- They sometimes change your meaning
Cloud & apps
Grammar tools are built for this job and mark the problem instead of rewriting the whole piece.

Our take
For grammar, a dedicated checker is the better tool. Stay local when the text itself is confidential.
Choose local if…
- The text is private
- You only need a light rewrite
Choose cloud if…
- You want the mistake marked
- You live in Word or a browser
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 8B 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.
