About Mewmori and Nullstack

In their own words, as submitted to SaaSHub.

Mewmori
Nullstack

Mewmori is a pixel cat that lives on your Mac desktop and gets to know you. It asks your name, takes the one you give it, then asks what you do. After that it remembers. Not a chat log: facts. What you work on, what you like, what kept you busy last week. Days later it brings that up on its own....

Features and specs

What each product offers, as listed by its team.

Mewmori 5 features
Nullstack 5 features
  • Gamified Learning Experience
    Mewmori appears to use gamification elements with a cat theme to make language learning more engaging and fun, which can help maintain user motivation and make studying feel less like a chore.
  • Accessible Web Platform
    Being web-based, Mewmori can be accessed from any device with a browser without requiring users to download and install a separate application, making it convenient for quick access.
  • Appealing Visual Design
    The cat-themed branding and mascot likely create a friendly, approachable aesthetic that can make the learning process feel more welcoming, especially for younger users or those who enjoy cute character-based interfaces.
  • Potential for Spaced Repetition
    Given the name's similarity to 'memory,' the platform may incorporate spaced repetition or memory-based learning techniques, which are scientifically proven to improve long-term retention of vocabulary and concepts.
  • Multilingual Support
    The URL structure suggests support for multiple languages (indicated by /en/ for English), meaning the platform may cater to a global audience with localized content.
  • Full-Stack Capabilities
    Nullstack allows for the development of both client-side and server-side functionalities within a single project, providing a more unified development process.
  • Seamless SSR
    It offers built-in support for server-side rendering, improving performance and SEO without the need for complex configurations.
  • Zero tooling
    Nullstack provides a setup that requires minimal configuration and does not depend heavily on additional tools, simplifying the development workflow.
  • Component-based Architecture
    Promotes the use of components, encouraging modularity and reusability of code, which can improve maintainability and scalability of applications.
  • Hot Module Replacement
    Supports HMR, allowing developers to see immediate changes in their applications without refreshing the entire page, improving development efficiency.

Possible disadvantages

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.

Questions & Answers

As answered by people managing Mewmori and Nullstack.

What makes your product unique?

Mewmori's answer

The memory is about you, not about the conversation. It keeps facts, not transcripts, and returns to them days later without being asked.

And there is no cloud path to fall back on. The model runs on your Mac through llama.cpp, so there is no setting that sends a reply, a screenshot or a memory anywhere else.

Why should a person choose your product over its competitors?

Mewmori's answer

It is a cat first. It has its own day: food, zoomies, hide-and-seek, a herb garden, expeditions. The talking sits inside that life instead of replacing it, so what you get on the desktop is company, not another panel.

Everything runs locally, the app is free, and the paid part is cosmetic. Skins and accessories, bought once, no subscription.

How would you describe the primary audience of your product?

Mewmori's answer

People who keep a Mac open all day: developers, designers, writers, students. It reads the screen for context and remembers across sessions, so it pays off for someone who works in one place for hours, not someone who opens the laptop twice a week. Russian and English.

What's the story behind your product?

Mewmori's answer

The name reads two ways. Mew plus memory, a cat that remembers you. And memento mori. The second reading is deliberate: the cat has a life of its own going on whether you look at it or not.

It started as a desktop pet and turned into a memory problem. Making a cat move is easy. Making it bring up, a week later, the one thing you told it once is the part that took the work. Built by one developer; first public release 18 August 2026.

Which are the primary technologies used for building your product?

Mewmori's answer

Swift 6 and SwiftUI, a native macOS app, universal binary for Apple Silicon and Intel.

Conversations: llama.cpp with a Qwen 3.5 2B model in GGUF, running on Metal.

Screen context: ScreenCaptureKit and Vision, OCR on device.

Updates: Sparkle.
