ContextBolt Radar vs Distill.io (2026 Comparison)

Distill.io is a favorite among people who monitor web pages seriously. It runs as a browser extension and a cloud service, it is flexible, and it is cheap to start. If you want to watch a specific page and you like control, it is a strong tool.

ContextBolt Radar is the competitor-monitoring server I built for people who want the conclusion rather than the configuration. It watches your rivals and tells you what matters, inside your AI agent.

Full disclosure, since you are reading this on the ContextBolt site. I make one of these. Here is the honest comparison, and Distill.io takes real wins.

What Distill.io is

Distill.io is a website change monitoring tool that works two ways. As a browser extension it can watch pages locally, including ones you can only see while logged in, and as a cloud service it checks pages on a schedule and alerts you by email, SMS, or push. You select the exact part of a page to watch, set conditions, and choose how often to check.

Pricing is friendly. There is a free tier with 25 monitors and 1,000 cloud checks a month, then Starter at $15 a month, Professional at $35, and a usage-based Flexi plan from $80. It handles text, visual, and numeric changes, which makes it popular for price tracking, stock alerts, and research.

Its strengths are flexibility and control. Local monitoring is a genuinely distinctive feature, and the granular selectors let you watch precisely what you want. The trade is the one every general detector makes. It watches what you tell it and leaves the meaning, and the ranking, to you.

What ContextBolt Radar does differently

Radar gives up the flexibility on purpose, to do one job completely.

You name up to 5 competitors. Radar finds and watches each one’s pricing, homepage, changelog, sitemap, and search footprint, checks them every night, and an AI model judges each change, so a new price reaches you and a rotated testimonial does not. You get a Monday briefing of what actually moved. And because Radar runs inside your AI agent over the Model Context Protocol, a real move turns into a drafted response, the comparison page or the post, written with your files and your voice.

You do not configure monitors or write conditions. You name competitors and read judged results. The work Distill.io leaves to you, deciding what matters and what to do, is the work Radar does.

Where Distill.io is the better pick

Distill.io is the right tool in real cases.

You need to watch any page, not just competitors: Restocks, ticket pages, research sources, anything with a URL. Radar only watches competitor domains, so for general monitoring Distill.io wins.

You need local, logged-in monitoring: The browser extension can watch pages behind your own login, locally, which a cloud-only tool like Radar cannot do.

You want a free tier or the lowest price: Free to start, $15 a month for real cloud usage. If budget is the deciding factor and you are happy to configure it, Distill.io is hard to beat.

You want visual and numeric diffs: Distill.io shows visual changes and tracks numbers like prices directly, which is ideal for deal hunting and precise tracking.

Where ContextBolt Radar is the better pick

Radar wins whenever you want competitive intelligence rather than a configurable detector.

You want the noise gone: Aim any detector at a busy competitor and most alerts are meaningless. Radar judges first, so you only see real moves and never learn to ignore the feed.

You do not want to configure monitors: Radar takes a domain and covers the right surfaces automatically, including the search footprint Distill.io does not track.

You want competitor meaning, not raw diffs: Radar reads a change the way a competitor would, in context, instead of reporting that some text on a page is now different.

You want the response drafted: When a rival moves, your agent drafts the reply right there with your context. Detection and response in one place, which no standalone detector offers.

Who should pick what

Pick the line that sounds like you.

Choose Distill.io if:

• You need to watch any page, not only competitors
• You want local monitoring of pages behind your own login
• You want a free tier or the cheapest paid path
• You are happy to configure monitors and judge the changes yourself

Choose ContextBolt Radar if:

• You specifically want to watch competitors and act on what changes
• You want the cosmetic noise filtered out automatically
• You want a rival’s search and pricing trajectory, not just page diffs
• You work in Claude, Cursor, or Codex and want the response drafted for you

The honest summary: Distill.io is a flexible detector for people who want control and a low price. Radar is an analyst for people who want the judged answer and the first draft. If configuring the watcher is fine by you, Distill.io is cheaper. If knowing what the change means and what to do is the point, that is Radar.
