## PixieBrix

PixieBrix began as a low-code way to customise web applications in the browser and has grown into an enterprise security and productivity platform. Its core product is the VIA Extension, a managed browser extension that brings Secure Enterprise Browser controls to Chrome, Edge, Island, Prisma and other Chromium browsers — without asking the workforce to migrate to a new browser.

The value proposition is workflow-level visibility and control. Network-based tools see traffic, while system logs record what happened around an action; PixieBrix focuses on the action itself inside the browser. That includes click and field-edit context, cross-tab interaction matching for dynamic authorisation, and the ability to monitor or block the same actions whether a human or an AI agent performs them.

The platform is particularly strong in contact centres and other high-volume front-line environments, where it targets revenue leakage from off-policy refunds and discounts, account abuse, fraud patterns such as reused shipping addresses and loyalty-point theft, and last-mile data loss through copy, paste and typing. It deploys in days rather than months, works on any OS including Chromebooks, and integrates with more than 3000 APIs.

**Pricing & Plans:** PixieBrix uses per-user subscription pricing with monthly or annual billing. Starter is aimed at small teams, Business adds AI/low-code custom controls, 3000+ API integrations, an MCP investigation server and SIEM integration, and Enterprise adds SSO, audio capture, white-labelling and support SLAs at custom pricing. Enterprise customers can request a free sandbox to evaluate technical controls.

- **Secure Enterprise Browser via extension:** PixieBrix deploys as a managed extension to monitor human and AI actions in any web app — including third-party sites — with full browser context that network controls miss.
- **Real-time policy enforcement:** Configure group policies in minutes to monitor, warn, soft-block or block actions, with built-in contact-centre and anti-fraud controls plus AI-code and low-code custom controls.
- **Revenue protection and audit:** Cover refund and discount integrity, shipping and loyalty fraud, payment-card masking, and flag snooping, bulk exports and after-hours activity.
- **Audit logs and investigations:** Every browser action is logged with on-screen context, backed by user risk scoring and an MCP investigation server for correlating data sets.
- **3000+ API integrations:** Connect to over 3000 APIs — chat, spreadsheets, project management, CRM — or define your own integration with any REST API.

**Strengths:** Protects where work actually happens, in the browser, without a new browser deployment; Covers both human and AI agent actions across third-party web apps; Fast deployment in days on any OS, including Chromebooks; Built-in contact-centre and anti-fraud controls plus custom low-code authoring

**Limitations:** Pricing is per-user and oriented to teams, so solo users are not the target; Starter plan excludes the no-code custom controls and 3000+ API integrations; Deployment requires browser extension management across the organisation; Enterprise pricing is quote-only

## Sider

Sider is a browser-first AI assistant built around a single sidebar that sits next to whatever you are reading or doing. Instead of juggling tabs for different chatbots, you get one interface that routes your request to frontier models — GPT, Claude, Gemini, Grok, DeepSeek, GLM and others — and returns an answer in context. The core Chat mode summarizes long articles, explains difficult concepts, and translates pages, PDFs, images and videos in place.

The platform has expanded well beyond chat. Sider Hand is an AI browser agent that works across the websites you are already signed into: it compares prices while you shop, fills in forms, runs multi-site research and triages your inbox. Sider Code lets you describe changes to any website in plain language and keeps them for future visits, while the Create studio generates images, video, slides and documents. Extra tools include ChatPDF, an AI translator, read-aloud, data analysis and a writing assistant.

Sider is distributed as a Chrome and Edge extension plus native macOS, Windows, iOS and Android apps, all tied to one account. The product reports 10M+ active users and 100K+ five-star ratings, with Chrome Editors' Picks and Favorites of the Year recognition. It is a freemium product: a free tier covers everyday use, and paid plans scale credits and cloud-computer power for heavier, always-on agent work.

**Pricing & Plans:** Freemium. A free tier covers everyday chatting, summarizing, translation and web access. Paid tiers are roughly US$10/month (Nano), US$25/month (Lite), US$50/month (Pro) and US$100/month (Max); every tier includes the same features, with higher plans adding more monthly credits and a stronger dedicated cloud computer for the browser agent. Annual billing offers a discount.

- **One sidebar for frontier AI models:** Ask questions and query any page with leading models such as GPT, Claude, Gemini, Grok, DeepSeek and GLM, and switch between them in one place.
- **Summarize, translate and explain on page:** Summarize long articles, explain hard concepts, and translate web pages, PDFs, images and videos without leaving the tab you are reading.
- **Browser agent that finishes tasks:** Sider Hand runs multi-step research, price comparison, form filling and inbox triage across real websites, using your existing logged-in sessions.
- **Content creation and AI studio:** Generate images and video, build slides and documents, and work with ChatPDF, read-aloud, data analysis and an AI writer inside the same sidebar.
- **One account across every device:** Sync chats and settings across Chrome, Edge, macOS, Windows, iOS and Android from a single account.

**Strengths:** Works inside the browser alongside your normal workflow instead of in a separate chat app; Access to many leading models — GPT, Claude, Gemini, Grok, DeepSeek and more — from one interface; The Hand agent can operate the sites you are logged into, enabling real multi-step automation; Broad feature set beyond chat: translation, PDF and video summaries, image generation and writing

**Limitations:** Credit-based plans mean heavy users can exhaust their monthly allowance quickly; The paid tiers are far more expensive than a single standalone model subscription; Runs inside the browser, so it cannot fully replace dedicated desktop automation tools; Some advanced agent features require an account and a paid plan to be useful
