The Structured-Extraction Alternative to Jina Reader

Structured data, not just clean text

Jina Reader's core output is markdown — great for feeding an LLM raw content, but you still need the model to parse specific fields out of it. AlterLab can return a structured JSON schema (e.g., price, title, availability) directly, skipping an extra LLM extraction step.

Handles pages that need more than a reader

Jina Reader is optimized for straightforward content extraction. AlterLab adds 5 tiers of automatic website compatibility handling — including full browser rendering — for JavaScript-heavy or access-gated pages that a simple reader can struggle with.

Per-request pricing, not token-volume billing

Jina Reader bills by tokens processed, which can make cost estimation harder for content-heavy pages. AlterLab charges a flat per-request rate based on the tier required, making cost predictable regardless of page length.
