Your Vector Database Deserves Better.
You've built the perfect chatbot, but it keeps hallucinating. Most file converters strip away the context. They mash headers, footers, and captions into one messy block of text. When your data has no structure, your AI has no context.
Image Descriptions
Images are converted to text descriptions so context doesn't get lost.
Tables
Tables built as images are converted into a text table that your LLM can understand.
Repetative Content Removal
Page numbers, disclaimers, document labels and other repetitive content are removed to save space and improve readability.
Maintain Structural Integrity
Each header, subheader, and paragraph is identified to make it easier for LLMs to understand the context.
Diagram Translation
Important diagrams are translated to text that your LLM can read and understand.
What Works Best
Not all documents are created equal. Some convert beautifully to AI-ready formats, while others need specialized handling.

How do credits work?
Generous limits, transparent costs. One credit goes a long way.
- Universal Conversion: Spend just 1 credit to transform a document up to 100 pages into Markdown, HTML, and JSON simultaneously.
- Smart Chunking: Spend 1 credit to deep-clean, header-optimize, and chunk that same 100-page file.
- Page Limit: Maximum 100 pages per document. This covers most PDFs while keeping pricing simple.
Why credits?
What is a conversion?
What is Chunking and why is it 1 credit?
Precision takes a second pass. Chunking is a specialized optimization step distinct from basic conversion. After the initial clean, we run a deep polish - injecting context headers and scrubbing any remaining noise like page numbers.
Finally, we segment your data into smart, digestible blocks (under 400 characters). This ensures your LLM retrieves exact answers without getting distracted by "garbage" data. See the data behind our chunking strategy.

How do credits and page limits work?
1 Credit = 1 Action per 100 Pages.
- Documents up to 100 pages = 1 Credit
- Documents 101-200 pages = 2 Credits
- +1 Credit per additional 100 pages
The optional AI Clean & Chunk follows the same scaling.
