The passage, not the whole page
Give an agent the paragraphs that answer a question, with the surrounding lines, instead of a scraped page.

Difficulty is an editorial estimate of technical and operational complexity, not a score.
Startup idea analysis by Startup Ideas. Last reviewed Oct 6, 2026. How we read a launch.
The startup idea
Context Highlights is a web extraction step from Context.dev. You give it a URL and a query, and it returns the passages that match, with surrounding lines so the agent can read them. The post says a full page fetch wastes the context window. It also states an efficiency comparison. That comparison is the company’s claim. This note does not repeat it as a measurement.
The opportunity is the cut, not another browser agent. Someone already has an agent that fetches pages. The useful product is the part of the page that answers the question, small enough to keep, with enough neighboring text that the sentence still means something. A founder can sell that as an API to people who can see their traces and their bill.
A ten-second film is a feature, not a company by itself. The company is the job that repeats: research, support, or price checks, where the page is long and the answer is a paragraph.
The problem
Fetching a URL dumps a page into the context window. Most of it is not the answer, and the bill follows.
Who would pay for this?
- Primary
- Developers whose agents already browse, and who read the trace.
- Secondary
- A team paying for context they can see is mostly navigation and ads.
- Early adopter
- Someone who has already watched an agent quote the wrong part of a page.
How could it make money?
Possible models. Nothing here is a claim about what Context.dev charges.
- An API priced on the pages it reads, once a team depends on the cut.
- The launch does not list a price. Do not invent one, and do not resell the efficiency claim.
What would the MVP look like?
- One URL.
- One question.
- The passages, plus the lines around them.
- A way to open the page and see what was left out.
How to validate the idea
- Run it on twenty pages your own agent already fetched. Compare the answer with and without the cut.
- If the answer gets worse, you cut too hard.
- Ask three developers to leave it on for a week. The ones who remove it have told you the passages were the wrong ones.
How to differentiate
- One kind of page, such as docs, filings, or product pages.
- Show what you dropped. A black box cut is hard to trust.
- Stay an API. Do not ship another agent.
- Keep the neighboring lines. A sentence with no neighbors is a slogan.
Original product launch
This launch is inspiration and evidence that someone shipped, not a partnership. The idea above is our reading of the broader opportunity. Context.dev did not write it.

Product that inspired this idea
Given a URL and a question, it pulls the passages an agent needs instead of the whole page. The efficiency claim in the post is the company’s.
