From Web Pages to Searchable Knowledge

A deterministic extraction engine normalizes any website into structured datasets. Search, filter, and export. AI is optional, not required.

Deterministic Extraction

Extract headings, paragraphs, tables, images, and links into normalized Universal Extraction Datasets. No AI black box — you get exactly what you see.

Full-Text Search

Every extraction is indexed with GIN-based full-text search across all sections, tables, and metadata. Find anything instantly.

Multi-Format Export

Export to Markdown, JSON, or CSV. Your data is portable and machine-readable. No vendor lock-in.

Organized Research

Group extractions into projects and collections. Tag, filter, and star your findings. Build a personal knowledge base.

Optional AI Layer

When you need analysis, ask questions against your structured datasets. AI works on your data, not in place of it.

Universal Extraction Dataset

Every page becomes a normalized record with sections, tables, images, links, metadata, and JSON-LD. Query it like a database.

Save Everything You Find. Find Everything You Saved.

Stop losing research in bookmarks, tabs, and notes. Jeterio turns web pages into a permanent, searchable knowledge base.
