Features and specs

What each product offers, as listed by its team.

Agentmemory 5 features
Side Space 4 features
  • Simple API
    Agentmemory provides a straightforward and minimal API for creating, searching, updating, and deleting memories, making it easy for developers to integrate memory capabilities into AI agents without dealing with complex configurations.
  • Built on ChromaDB
    It leverages ChromaDB as its underlying vector database, providing reliable semantic search and embedding capabilities out of the box without requiring developers to set up separate infrastructure.
  • Lightweight and Easy to Install
    Agentmemory is a lightweight Python package that can be installed via pip with minimal dependencies, making it quick to get started with and easy to incorporate into existing projects.
  • Category-Based Memory Organization
    Memories can be organized into categories (topics), allowing agents to store and retrieve information in a structured way, which helps with context management and retrieval accuracy.
  • No Server Required
    Agentmemory can run entirely locally without needing a separate server or cloud service, making it suitable for development, prototyping, and privacy-sensitive applications where data should stay on the local machine.

Possible disadvantages

  • Limited Ecosystem and Community
    Agentmemory is a relatively niche and small project with a limited community compared to more established memory and vector database solutions, which means fewer resources, tutorials, and community support are available.
  • Basic Feature Set
    While simplicity is a strength, the library may lack advanced features such as sophisticated memory consolidation, decay mechanisms, importance scoring, or complex querying capabilities that more mature memory frameworks offer.
  • Tight Coupling to ChromaDB
    Being built specifically on ChromaDB means developers are locked into that particular vector store and cannot easily swap it out for alternatives like Pinecone, Weaviate, or FAISS without significant refactoring.
  • Limited Scalability
    As a locally-run, lightweight solution, Agentmemory may not scale well for production applications that require handling large volumes of memories, high concurrency, or distributed deployments.
  • Sparse Documentation and Examples
    The project's documentation, while covering the basics, may lack comprehensive examples, best practices, and advanced usage patterns that developers need when building complex agent-based systems.
  • 🌈 Arc-like Side Panel
    We’ve built an Arc-like side panel that transforms your tabs into a sleek vertical layout, making it easier than ever to navigate and manage your workspace.
  • 🧠 Smart AI Grouping
    It’s not just about organizing tabs—it’s about doing it intelligently. Our AI grouping feature clusters tabs based on content for a streamlined experience. Plus, you have control with our Group Guardian feature, letting you customize tab groupings using URL matches to set your own organizational rules.
  • ☁️ Spaces & Cloud Sync
    Take productivity to the next level! Save your tabs into different Spaces and we automatically sync them to the cloud. Your organized tabs are accessible across devices, so you can browse seamlessly wherever you are.
  • 🤖 AI Assistant
    Research, summarize, and organize, chat with your tabs and let Al Assistant help you browse smarter.

Questions & Answers

As answered by people managing Agentmemory and Side Space.

What makes your product unique?

Side Space's answer:

Side Space combines powerful vertical tab management with an integrated AI assistant, that's something no other browser extension offers.

Instead of choosing between a better tab manager or an AI browser, Side Space gives you both in one clean side panel.

What's the story behind your product?

Side Space's answer:

I am the kind of person who always ends up with too many tabs, too many windows, and no idea where that one page I read yesterday has gone. I tried a bunch of the new AI browsers, but they all felt like replacements for tools I already rely on. I didn’t want a new browser. I just wanted my existing one to feel less chaotic.

So I built Side Copilot for myself first. It helps me manage tabs, jump between windows, find stuff I opened days ago, and generally clean up the mess I constantly create. The thing that changed everything for me was giving it the ability to understand natural commands. I can tell it to group my research tabs or bring back an article from last week and it actually does it. It also has a simple chat mode for quick summaries or translating a page on the spot.

I realized it solved a real problem for me, so I decided to make Side Copilot completely free. I’m curious how other heavy browser users feel about this. Would an assistant like this make your browsing less stressful?

Why should a person choose your product over its competitors?

Side Space's answer:

  1. The world’s first AI assistant built for your tabs

Most AI tools only analyze text. Side Copilot controls your tabs, windows, history, and pages using real browser APIs. You can research, summarize, organize, open sites, perform searches, restore sessions, and automate actions — all with natural language.

  1. A true vertical tabs manager, not a browser replacement

You don’t need to switch to Arc or Edge. Side Space turns Chrome’s side panel into a clean vertical tabs system with:

Drag-and-drop tab & group management

Fuzzy search

Memory-saving tab suspension

Saved spaces & session restore

Cloud sync

Dark mode

You get a modern browser experience without leaving Chrome.

  1. Dual AI modes for different tasks

Chat Mode → instant content analysis (summary, translation, extraction, quick answers)

Agent Mode → deep automation (organize tabs, clean up windows, run research workflows)

Fast when you need speed, powerful when you need automation.

  1. Page, tab, window, and history tools powered by real browser capabilities

Side Copilot isn’t “just another chatbot.” It uses more than 20 AI MCP tools built on Chrome Extension APIs:

Tab tools: create, close, group, move

Window tools: tile, arrange, focus

History tools: analyze, find, reopen past pages

Page interaction tools: scroll, navigate, search, capture screenshots

Session tools: restore recently closed tabs/windows

This gives Side Space automation capabilities even AI browsers don’t have.

How would you describe the primary audience of your product?

Side Space's answer:

Side Space is designed for anyone who works, researches, or creates directly in the browser — especially those who manage dozens of tabs every day. If the browser is your workspace, this is for you.

Productivity-Driven Professionals

Marketers, PMs, developers, designers, analysts — anyone who needs a smarter, faster way to organize tabs, windows, and workflows.

Power Browsers with Endless Tabs

For users juggling 20–200+ tabs across multiple windows. Side Space brings structure, clarity, and smart automation without forcing you to switch browsers.

AI-Forward Users

If you want to control your browser with natural language, automate tasks, and let Side Copilot handle the heavy lifting, this is your perfect tool.

Researchers & Knowledge Workers

Students, academics, journalists, content creators, and anyone who collects and analyzes information online. Summarize, extract, search, and research pages instantly.

People Who Want Arc/Edge-Style Features — But in Chrome

Enjoy a vertical tabs manager, powerful side panel, and full AI assistant experience without giving up the browser you already love.
