Running AI on your own computer used to mean terminal commands, 30 to 40 GB downloads, and a painful guess: will this model even start on my machine? RigSpark AI fixes that first step. It checks your memory, graphics card and disk space, tells you which models will run, which will be slow and which will not run at all, and then runs them for you — chat, images, video and voice — all offline. In this guide you will learn how to use RigSpark AI for free, from installation to your first local chat, with no account, no cloud and nothing metered.
RigSpark launched on Product Hunt on 10 November 2026, and it is free and open source under the MIT licence. It works on macOS, Windows and Linux, as a desktop app or a command-line tool. If you have ever wanted a private ChatGPT-style assistant that lives on your own laptop, this is one of the easiest ways to get one. You do not need a powerful gaming PC either: small models run on an ordinary CPU, and RigSpark tells you honestly what fits before you download anything.
Step 1: What Is RigSpark AI and Why Run AI on Your Own Computer?
RigSpark is a free, open-source app that runs open AI models directly on your computer. Instead of sending your prompts to a company server, everything happens on your own machine. That brings three big advantages for beginners: privacy, cost and control.
Privacy: your chats, documents and images never leave your computer. RigSpark sends no usage data, and its local servers listen only on your own machine, never on your network.
Cost: there is no subscription and no per-message charge. Once a model is downloaded, you can use it as much as you like, even with no internet connection.
Control: you choose the model. You can run Llama, Qwen, Gemma and DeepSeek models, switch between them in seconds, and even add any model from Hugging Face.
Running AI locally is also a smart move for small businesses. A digital agency that handles client documents, for example, can keep sensitive work on its own machines instead of uploading it to a cloud chatbot. Local AI is not a replacement for every cloud tool, but for everyday writing, brainstorming, coding help and image generation, a good local model is now genuinely useful — and RigSpark makes the setup painless.
Step 2: Check Whether Your Computer Can Run AI Models
Before you download any model, you need to know what your computer can handle. A model is a very large file, and it needs enough memory to load. This is the step where most beginners get stuck — they download a 40 GB model, wait an hour, and then discover their laptop cannot run it. RigSpark removes that guesswork completely.
When you open RigSpark, it reads your system for you: how much RAM you have, what graphics card is installed, and how much free disk space is available. Every model then gets a simple verdict: yes, slow or no, with the reason shown next to it. A "yes" means the model fits comfortably. "Slow" means it will run, but answers will take longer — usually because it must run on the CPU instead of the GPU. "No" means the model needs more memory than your machine has, so you should pick a smaller version instead.
8 GB of RAM: stick to small models around 3 to 8 billion parameters, such as Llama 3.1 8B or Gemma 3 4B. These are fast enough for chat, summaries and everyday writing.
16 GB of RAM: you can run most 8B and some 14B models comfortably, plus image generation.
32 GB of RAM or more, or a dedicated GPU: larger models open up, including 32B models and video generation.
Apple Silicon Macs: RigSpark uses the built-in Apple Silicon GPU, so even a base MacBook Air runs small models well.
You can also check a single model before downloading it with the command rigspark can-run llama3.1:8b. RigSpark shows the download size and the memory the model needs, so there are no surprises.
Step 3: Download and Install RigSpark on Mac, Windows or Linux
Installation takes about five minutes, and there is no account to create. RigSpark is written in Rust and has shipped 38 releases since August 2026, so it is actively maintained and stable.
On a Mac: download the app from the official releases page. The Mac app is signed and notarised by Apple, so it opens normally. Homebrew users can install it with brew install shashankswe2020-ux/tap/rigspark.
On Windows: run the installer — no administrator rights are needed. The installer is not code-signed yet, so Windows SmartScreen may show a warning. If it does, choose "More info" and then "Run anyway". This is expected for now and does not mean the file is unsafe; always download from the official releases page.
On Linux: there is no desktop app yet. Install the command-line tool from the releases page and run rigspark gui — the same app opens in your browser. On Linux, an NVIDIA GPU works through Ollama or llama.cpp.
Once installed, open RigSpark and let it scan your hardware. It will show you a short list of starter models that fit your computer. Pick one, click "Download and start", and RigSpark verifies the file and starts the model for you. Nothing else needs to be installed for chat — RigSpark handles the runtime (Ollama, llama.cpp, MLX, LM Studio or BitNet) behind the scenes.
Step 4: Let RigSpark Pick Your First Model
Choosing a model is the hardest part of local AI for beginners, because model names look like alphabet soup: Llama 3.1 8B, Qwen3 14B, Gemma 3 4B, DeepSeek-R1 8B. The number tells you the size in billions of parameters. Bigger usually means smarter, but also slower and hungrier for memory. RigSpark turns this choice into a one-click decision.
After the hardware scan, RigSpark recommends a starter model that fits your computer. For most beginners on a normal laptop, that will be a 7B or 8B chat model — fast, capable, and small enough to download in a few minutes. Accept the recommendation for your first run. You can change models later in seconds, and RigSpark keeps every model you download in a library, so switching is free.
For everyday chat and writing: Llama 3.1 8B or Qwen3 8B. Both are strong all-rounders.
For coding help: Qwen3 Coder or DeepSeek-Coder models, which are tuned for programming.
For reasoning and maths: DeepSeek-R1 distilled models, which show their working step by step.
For the smallest, fastest option: Gemma 3 4B or a 3B model, ideal for older laptops.
Each model card shows its download size before you start, so a slow connection is never a surprise. RigSpark downloads models only when you ask it to, and it verifies every file after the download, so a corrupted file is caught before it wastes your time.
Step 5: Start Your First Local Chat with RigSpark AI
With a model running, the chat window works like any chatbot you already know — but everything stays on your machine. Type a question, press Enter, and the answer appears, generated locally. There is no usage limit and no "you have reached your free tier" message.
Try these first prompts to get a feel for what your local model can do:
"Explain quantum computing to me like I am 12 years old."
"Write a polite email asking my manager for two days off next week."
"Give me five healthy breakfast ideas I can make in ten minutes."
"Summarise this paragraph in three bullet points:" followed by any text you paste in.
Notice the speed. On a machine with a decent GPU or Apple Silicon, a small model answers almost instantly. On a CPU-only laptop, answers arrive word by word, a little slower — still perfectly usable for writing and brainstorming. If a reply feels too slow, switch to a smaller model from your library; RigSpark makes the trade-off visible instead of mysterious.
Your chat history is stored locally too. Close the app, reopen it tomorrow, and your conversations are still there — on your disk, not on a company server. For anyone who drafts sensitive work, that difference matters. Teams exploring AI automation services often start exactly here: a private local assistant for drafting, summarising and planning, before any data ever touches a cloud service.
Step 6: Generate Images and Short Videos Offline
RigSpark is not only a chatbot. From the same window, you can generate images and short videos from a text prompt, using image and video models that run locally on your computer. No credits, no queue, no watermark, and no account.
To create an image, switch to the image tab, type a prompt such as "a cosy reading nook by a rainy window, warm light, watercolour style", and press generate. The image appears in a few seconds on a good GPU, or a little longer on a CPU. You can copy the picture into any other app, or send it to connected tools such as Canva and Figma.
Be specific: name the subject, the setting, the lighting and the style. "A red bicycle leaning against a brick wall at sunset" beats "a bicycle".
Try styles: add "photorealistic", "watercolour", "3D Pixar style" or "minimal flat illustration" to the end of your prompt.
Video needs more power: short video clips need a stronger GPU and more memory. If video is slow on your machine, generate the image first and keep video for a smaller size.
Save what you like: generated images are stored locally, so build a folder of favourites you can reuse in posts and presentations.
Image and video generation is set up for you on macOS and Windows. On Linux, RigSpark can use your own ComfyUI installation instead. If you are new to AI images in general, the same prompting habits you learn here transfer directly to every other image tool.
Step 7: Talk to RigSpark: Voice Chat and Dictation
Typing is not the only way to use RigSpark. It can read its replies aloud, and you can dictate instead of typing — handy when your hands are busy, or when you simply think faster out loud than you type.
Turn on voice replies in the chat window and RigSpark will speak its answers using a local voice model. Dictation works the other way: hold the microphone button, speak your question, and RigSpark transcribes it into text before answering. Because the voice models also run locally, your voice never goes to a cloud server either.
Voice is genuinely useful for a few everyday jobs: dictating a first draft while you walk around the room, asking for a recipe while your hands are covered in flour, or letting the assistant read a long summary aloud while you do something else. Small models handle short voice tasks well; if transcription feels sluggish, switch to a smaller speech model in the settings. The key point for beginners is that voice is built in — there is no separate app to install and no extra account to create.
Step 8: Add Any Model from Hugging Face
The built-in model library covers the popular choices, but the real power of open AI is the thousands of models on Hugging Face. RigSpark lets you add any of them. Paste a Hugging Face repository link into RigSpark, and it sizes every version of that model against your machine, then picks the largest one that fits. You never have to work out which quantisation file to download — RigSpark does the maths for you.
This is useful when you need something specific: a model fine-tuned for medical notes, a legal assistant, a model that speaks your language better, or a tiny model for an old laptop. Community models appear on Hugging Face every day, and a good way to discover them is to search for your use case plus "GGUF" — the file format most local runners use. Always check the model's licence and its download count before installing, and prefer models with clear documentation and recent updates.
A practical tip: keep your library small. Three or four models you actually use beat twenty you never open. Each model takes gigabytes of disk space, so delete models you have stopped using from the library view. RigSpark shows the size of each one, so the clean-up takes a minute.
Step 9: Connect RigSpark to Claude Code, Codex and OpenCode
RigSpark becomes even more useful when your other AI tools can use your local model. With the rigspark connect command, you can point coding agents such as Claude Code, Codex or OpenCode at a model running on your own computer. Your code stays local while the agent helps you write, explain and debug it — a big deal for developers working on private or client projects.
The setup is simple: start the model in RigSpark, run rigspark connect in your terminal, and choose the agent you want to connect. RigSpark serves the model through a local address, and your coding agent talks to it just like it would talk to a cloud model. When you are done, stop the model and the local server closes. Nothing about your code ever leaves the machine.
For beginners, this step is optional — the built-in chat already covers most needs. But if you write code and you care about privacy, this one command is the difference between "my code goes to a server" and "my code stays here". It is also a gentle introduction to how local AI fits into real developer workflows, without needing to learn server administration.
Step 10: Stay Private and Fix Common Problems
Local AI is private by design, but a few habits keep it that way and keep it running smoothly. RigSpark goes online only to download models and updates you ask for. Advice and chat work fully offline, and it sends no usage data anywhere. Its local servers listen on 127.0.0.1, which means only your own computer, not your network, can reach them.
Here are the most common beginner problems and their fixes:
"This model will not run": trust the verdict. Pick a smaller version of the same model family, or a smaller model entirely. A 3B or 4B model that runs is better than a 32B model that does not.
Replies are very slow: close other heavy apps to free RAM, switch to a smaller model, or shorten your prompts. Long conversations also slow models down, so start a fresh chat for a new topic.
Downloads fail or stall: check your internet connection and free disk space. Models are large files, and a full disk is the most common cause of a failed download.
Windows SmartScreen warning: choose "More info" then "Run anyway", but only if you downloaded the installer from the official releases page.
Images look odd: add more detail to the prompt, name the style, and try again. Image models improve dramatically with a specific prompt.
Running out of disk space: open the model library and delete models you no longer use. A single large model can free 20 to 40 GB.
One more privacy note: local models are only as private as the computer they run on. Keep your operating system updated, use disk encryption if your device supports it, and do not paste passwords or secrets into any chatbot — local or cloud. Good habits matter more than good software.
RigSpark vs Ollama vs LM Studio vs Cloud Chatbots
How does RigSpark compare with the other ways to run AI? The table below gives a quick beginner-friendly overview.
| Option | Best for | Ease of use | Cost | Privacy |
|---|---|---|---|---|
| RigSpark | Beginners who want a guided setup | Very easy — hardware check built in | Free, open source | Fully local |
| Ollama | Developers comfortable with commands | Easy, but terminal-based | Free, open source | Fully local |
| LM Studio | Visual model browsing on desktop | Easy, graphical interface | Free | Fully local |
| Cloud chatbots | Biggest models, no setup at all | Easiest — just sign in | Free tier, then paid | Data leaves your device |
RigSpark's advantage is the hardware check: it answers "will this run on my computer?" before you download anything, which is the exact question that stops most beginners. Ollama and LM Studio are excellent tools, and RigSpark can even use Ollama as its runtime behind the scenes — you are not choosing a rival, you are choosing a friendlier front door.
Frequently Asked Questions About RigSpark AI
Is RigSpark AI really free?
Yes. RigSpark is free and open source under the MIT licence. There is no account, no subscription and no usage meter. You download the app, download the models you want, and use them as much as you like. The project is built in the open on GitHub, and a star on the repository helps more people find it.
Can I use RigSpark AI without the internet?
Yes, once your models are downloaded. Chat, images, video and voice all work fully offline. RigSpark goes online only when you ask it to download a new model or an update. This makes it ideal for travel, for places with unreliable internet, and for anyone who wants a private AI assistant.
Do I need a powerful gaming PC to run RigSpark AI?
No. Small models run on an ordinary CPU with no GPU at all, and Macs use the built-in Apple Silicon GPU. With 8 GB of RAM you can run capable 3B to 8B models for chat and writing. A stronger machine simply unlocks larger models, faster answers and video generation — it is not a requirement.
How is RigSpark AI different from ChatGPT?
ChatGPT runs on company servers: your prompts travel to the cloud, and the most powerful models need a paid plan. RigSpark runs open models on your own computer, so your data stays private and there is no per-message cost. The trade-off is that local models are smaller than the biggest cloud models, so for the hardest tasks a cloud chatbot may still answer better.
Which models work best with RigSpark AI for beginners?
Start with Llama 3.1 8B or Qwen3 8B for general chat and writing. Both are fast, capable and well tested. If your computer is older or has only 8 GB of RAM, try Gemma 3 4B instead. RigSpark recommends a starter model after its hardware scan, so accepting its suggestion is the safest first choice.
Is my data safe when I use RigSpark AI?
Yes — your chats and files stay on your own computer, RigSpark sends no usage data, and its local servers listen only on your machine. That said, keep good security habits: update your operating system, use disk encryption if available, and never paste passwords or secrets into any AI chat, local or cloud.
Final Thoughts
Learning how to use RigSpark AI is one of the quickest wins in personal AI. In under half an hour you can go from a curious beginner to someone running a private AI assistant on their own computer — chatting, generating images, dictating notes and even connecting coding agents, all without an account or a subscription. The hardware check is the feature that makes it beginner-friendly: it replaces hours of guessing with a simple yes, slow or no before you download a single gigabyte.
Start small. Install RigSpark, accept its recommended starter model, and have one real conversation with it today — summarise an article, draft an email, or brainstorm ideas for a project. Once that first local chat clicks, try an image, try voice, and then add a second model from Hugging Face. Local AI rewards curiosity, and it costs nothing to explore. Your computer is more capable than you think, and now you have a free tool that proves it.
