Canopy filters explicit images and text across phones, apps, social feeds, and some AI chat tools. Sigma Vision does not try to win that surface area. It is a Windows and Mac blocker that can lock the whole desktop session after warnings. If you are comparing a Canopy alternative for compulsive use on a computer, compare what happens after detection, not who covers more apps.
Canopy vs Sigma Vision
| Canopy | Sigma Vision | |
|---|---|---|
| Phones and in-app content | Strong: this is the product | None |
| AI chatbots / social apps | Built for this | Only if it is visible on the Windows/Mac screen |
| Windows and Mac desktop | Supported as part of a wider suite | The entire product |
| After detection | Blur or block that content; device usually still usable | Warnings, then optional lock of screen, keyboard, mouse, voice |
| Reports to a parent dashboard | Family-oriented monitoring options | No partner reports; on-device only |
What Canopy is good at
Modern exposure is often not a porn site. It is a feed, a chat, a generated image. Canopy’s pitch is on-device filtering in those places. If that is your actual risk: a teenager’s phone, Discord, an AI image tool: Canopy is the more honest fit. We will not pretend Sigma Vision is a phone filter.
Where filtering is not enough
For compulsive use on a laptop, blocking one image and leaving the rest of the OS unlocked often means the next attempt starts in another window. That is a different failure mode than “Canopy missed a domain.” It is the session continuing.
What Sigma Vision does on the desktop
Blocklist for known adult sites. On-device AI on what is on screen. Then a lockout you configure. Details: how the three layers work.
Which one to buy
- Choose Canopy if phones, apps, and AI chat are the problem.
- Choose Sigma Vision if a Windows or Mac computer is where the habit lives and you need the session to stop, not only the image to blur.
- Some households use both. That is not duplicate spend if the devices differ.

FAQ
Does Sigma Vision filter ChatGPT or social apps like Canopy?
Only insofar as that content is on the computer screen. It is not a dedicated chatbot filter.
Does Canopy lock the whole PC?
Canopy’s model is filter-in-place. Sigma Vision’s third layer is a device lockout. That is the comparison that matters for compulsive desktop use.
