## 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's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
- **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans
