FOSS apps (all on Flathub)

Some of the AI related apps I've been using that are both Free Software and offline (where it runs on your computer without using network services in the cloud) are:

• OCR: "Frog" can take screenshots, select images, accept drag and drop, and you can paste an image from the clipboard. It'll read the text on the images and immediately have a text area with the result. flathub.org/apps/com.github.te… — it's powered by Tesseract. Note: The completely optional text-to-speech that Frog has does use an online service. But the rest is offline.
• Speech to text: "Speech Note" does text to speech, speech to text, and translations... all locally on your computer, and it supports GPU acceleration (which isn't needed, but it makes it a little faster). flathub.org/apps/net.mkiol.Spe… — This is basically the all-in-one "Swiss army knife" of ML text processing. Thanks to being a Flatpak, you don't have to do anything special for the dependencies. It's all taken care of for you. It also has tons of different models (for different voices, different backends) all available from within the UI, which just needs a click for downloading.
• Upscaling images: There are two that do something similar, using some of the same backends. A nice and simple one is "Upscaler". flathub.org/apps/io.gitlab.the… Another one that's cross platform is "Upscayl" flathub.org/apps/org.upscayl.U… — these both use ESRGAN and Waifu2x in the background.
• Closed captioning: "Live Captions" uses an ML model to transcribe text realtime. It's wonderful for when a video doesn't have subtitles, or when you're participating in a video call (which might also not have CC). There's also a toggle mode that will transcribe based on microphone input. The default is to use system audio. flathub.org/apps/net.sapples.L…
• Web page translations: Firefox, for the past few releases, has the ability to translate web pages completely local in-browser. It does need to download a small model file (a quantized one around 20 megabytes per language pair), but this happens automatically on first use. All you need to do is click the translate icon (when it's auto-detected) or go to the menu and select "Translate page...". Firefox is located in your distribution already (and is usually installed by default in most Linux distributions) and is available as an official package from Mozilla on Flathub as well. Newer versions keep improving on this, improving speed (it's pretty quick already), improving accuracy, improving reliability (sometimes you have to try to translate a couple of times on some pages), and adding languages. But what's there in the release of Firefox is already great.

Chat and image generation (more advanced)

While all the above are graphical apps and on Flathub (some may have distro packages too), there are some additional AI/ML things you can run on Linux as well:

• Chat ML: "Ollama" (ollama.ai/) is a friendlier wrapper around llama.cpp and lets you run a variety of models (some FOSS, some just source-available-and-gratis, some not at all).

You can run Ollama in a container to make it even easier. Even a Podman container on your user account works. (You don't need to set it up as a system container.) The instructions for Docker work on Podman (just swap the docker command for podman instead).

While the official instructions only list CPU (which is fine for some of the smaller models) and NVidia, it's also possible to use an AMD GPU too:

# Enable device as user (run once per boot)
sudo setsebool container_use_devices=true

# Set up the ollama server for AMD acceleration (run once per session)
podman run --pull=always --replace --detach --device /dev/kfd --device /dev/dri --group-add video -v ollama:/root/.ollama -p 11434:11434 --name ollama ollama/ollama:0.1.22-rocm

# Command-line interaction (run any time you want to use it — the last part is which model you want to use)
podman exec -it ollama ollama run llama2

If you want a web UI like ChatGPT, then you could also run this instead of the command line interaction command:

podman run -d --replace -p 3000:8080 --add-host=host.docker.internal:host-gateway -v ollama-webui:/app/backend/data --name ollama-webui ghcr.io/ollama-webui/ollama-webui:main

When done, run podman stop ollama and podman stop ollama-webui to free up resources from your GPU.

There are also integrations for text editors and IDEs, similar to GitHub's CoPilot. Neovim has a few already. VS Code (or VS Codium) has some too (like twinny and privy).

• Image generation: "Stable Diffusion" is the go-to here. There are a bunch of forks. Some of the better ones are:
  
  • "Fooocus" github.com/lllyasviel/Fooocus/ — an easy to use streamlined app (with some advanced settings) where you don't need to prompt as much or tweak settings to get a good result by default.
  • "SD.next" github.com/vladmandic/automati… — A fork of the Automatic111 fork of the default Stable Diffusion web app that uses the Gradio UI.
  • "ComfyUI" github.com/comfyanonymous/Comf… — A node-based UI for Stable Diffusion.
    ...and there are a ton others. Forks of forks of forks.

  
  

Krita, GIMP, and Blender all have plugins that can interface with some of these too (usually using a SD Automatic111 API).

For Stable Diffusion on AMD, you need to have ROCm installed and might need to set or use an environment variable to make it work with your card. Something like:
HSA_OVERRIDE_GFX_VERSION=11.0.0 or HSA_OVERRIDE_GFX_VERSION=10.3.0 (depending on your GPU). Prefixing means just putting that at the beginning of the the command with a space and then the rest of the command. Setting it as a variable depends on your shell. You might need to export it for some (like for bash). Prefixing it is fine though, especially when you use ctrl+r to do a substrang search in your shell history (so you don't need to retype it or remember silly-long commands).

As using these image generating apps pulls down a lot of Python libraries, I'd suggest considering setting up a separate user account instead of using your own, so the app doesn't have access to your local files (like stuff in ~/.ssh/, ~/.local/, your documents, etc.). Setting up containers for these is not so easy (yet), sadly. Some people have done it. And they do run in a toolbox or distrobox podman container... but toolbox and distrobox containers don't really contain so much, so you're better off using podman (with a "docker" container) directly or running it as a separate account for some type of isolation from your user account files.

Everything else above is at least contained (via containers or Flatpak) to some degree... but stuff locally via pip installs can do anything. And it's not just hypothetical either, for example: PyTorch nightly was compromised for a few days on Christmas of 2022.

There are some graphical apps on Flathub for connecting to Stable Diffusion and a ChatGPT AI (which ollama now has)... but in the course of setting them up, you basically have a web and/or text-based UI to interact with.

I accidentally learned about the “subsidized destruction of markets to enact a monopoly” strategy back in the 1990s. A friend of mine owned a photocopy shop (remember those?) in a small college town. Kinko’s came into town and offered copies for far less than it costs to make, eating the losses for as long as it takes to kill off their competitors. My friend of course went out of business, and shortly after, Kinko’s raised their prices to much higher than his prices would have been.

After personally seeing that strategy in action, I now see it everywhere. Walmart did the same thing by killing off local stores. Amazon did it with online shipping. Every startup’s “disruption” strategy is basically this technique in disguise: Uber, AirBNB, and of course, AI. It’s all about destroying an industry in order to monopolize and enshittify it for profit.
