Why Run AI Locally?

Local AI is software that runs some or all of its AI processing on your device. What stays on the device, what needs an internet connection, and what it costs depends on the app, model, and settings.

  • Privacy: When an app processes a prompt on your device and keeps it there, that information may stay local. Some apps connect to online services or sync data, so check how the app handles your information before using confidential material.
  • Internet access: Some local models can run offline after setup. Downloads, updates, sign-in, and connected features may still need internet access.
  • Costs: Some local options avoid per-prompt cloud charges. Software, a suitable PC, electricity, model downloads, or connected services can still cost money.
  • Speed: Responses depend on your PC, model, and app. Local processing avoids a cloud round trip, but a larger model or a less capable PC may take longer to respond.
  • Choice: Some apps let you choose a model or adjust settings. The available choices and how updates work depend on the software and its publisher.
  • Usage limits: A local model may avoid a cloud provider's message limits, but app licenses, model requirements, and your PC still set practical limits.

What Can Local AI Do?

Depending on the app and model, local AI tools may help with tasks such as:

  • Drafting and planning — draft replies, summarize notes, or organize ideas. Check important facts before using the result.
  • Document questions — some apps can work with PDFs or notes. File support and data handling vary by app, model, and settings.
  • Image tasks — some local tools can create or edit images; their hardware needs vary.
  • Audio and video — some tools can transcribe, summarize, or generate media.
  • Speech and transcription — some tools can turn speech into text or generate spoken audio.
  • Coding help — some models can explain or draft code and documentation. Review the output before using it.
  • Music generation — some local tools can generate music or other audio.

In short: Local AI may suit tasks where on-device processing matters. Whether it fits your business depends on the app's data handling, internet needs, supported features, costs, and how it runs on your PC.

Before choosing a local AI tool, check:

  • How the app handles prompts, files, and other business information
  • Whether setup or the features you need require internet access
  • Which models and tasks the app supports, and what they cost to run
