Web information extraction

KeyLens

Long pages, just the keys.

KeyLens turns the page you are already reading into a reviewable set of fields, tables and source links. Free tasks stay useful; Pro adds wider workflows.

Capabilities

A shorter path from page to dataset.

KeyLens combines page-type detection, local parsing and structured output in one browser workflow.

Page summary

Capture the title, summary, key points, author, date and source from an article.

Structured modes

Extract articles, products, contacts and list tables with field-level structure.

Reviewable results

See fields, row counts and confidence before you copy, save or export anything.

Practical exports

Copy results or export CSV. Pro adds JSON output and a searchable local history.

Workflow

One local extraction flow.

The process stays inspectable from the first page read to the final export.

01

Detect

Identify whether the page is an article, product, contact or list.

02

Extract

Parse visible fields, repeated rows and source links on the device.

03

Review

Check the result shape, row count and confidence before acting.

04

Export

Copy, save to history or download the result as CSV or JSON.

Plans

Free for everyday checks. Pro for heavier work.

The free tier completes real tasks. Pro adds broader page modes, higher limits and batch workflows.

Free

Everyday use

A practical local extractor for routine pages.

  • 12 successful extractions per day
  • Up to 30 rows per extraction
  • Page briefs and contact details
  • CSV export and clipboard copy

Pro

More throughput

More structure, more volume and multi-tab workflows.

  • Up to 300 rows per page
  • Batch extraction across 8 open tabs

Boundaries

Designed to stay transparent.

The interface makes processing location, limits and extraction confidence visible.

Local by default

Page text and extraction results stay in the browser. No remote AI service is required.

Honest boundaries

Empty results are not charged, and complex dynamic pages may return only part of the structure.

Browser-native setup

Manifest V3 and zero-build files make the extension straightforward to inspect and load.
