The semantic chunking platform · 2026

Master the Split. Perfect the Retrieval.

CHUNKZA AI replaces crude character-count chunking with layout-aware splitting, semantic boundary detection, and parent-child chunking — visualized end to end, so your RAG systems retrieve the right context, every time.

Why CHUNKZA

Garbage in, garbage out — fix it at the source.

In advanced RAG, retrieval quality is decided long before the model. It's decided by how you split. CHUNKZA treats chunking as a first-class engineering discipline.

01

Layout-aware splitting

We parse document structure — headings, tables, lists, captions — before we cut. Your chunks respect the document, not the character count.

02

Semantic boundary detection

A trained model predicts natural topic shifts inside long passages, so chunks end where meaning ends — never mid-sentence, never mid-thought.

03

Parent-child chunking

Retrieve on tight, cheap child chunks. Return the rich parent context to the model. You get recall and precision in a single pipeline.

04

Visualized end to end

See chunk boundaries, metadata injection, and embedding distribution in real time. Diagnose retrieval failures at the source, not in production.

Capabilities

A diagnostic panel for your retrieval pipeline.

Every feature is built to make the invisible visible — and the unfixable fixable.

All features
Pipeline

Hybrid strategy preview

Combine layout-aware, semantic, and overlap strategies in one pipeline and preview the result before you commit a single embedding.

Metadata

Metadata injection

Automatically tag each chunk with section path, source URI, page, and custom schema fields — query-aware retrieval out of the box.

Vectors

Embedding distribution map

Project your chunk embeddings into 2D space and spot clusters, outliers, and silent duplicates that drag down retrieval.

Compare

Boundary diff

Compare chunking strategies side by side. See exactly which boundaries moved, merged, or split — and what it does to recall.

Replay

Retrieval replay

Replay real queries against any chunking version and watch which chunks surfaced, in what order, with what score.

Structure

Schema-aware tables

Tables stay tables. Headers propagate to every row chunk, so numeric and structured retrieval stays coherent.

The pipeline

From raw document to semantic capsule — in four moves.

A clean, observable pipeline beats a clever black box. Every stage is inspectable, every decision reversible.

01

Ingest

Drop in PDFs, DOCX, Markdown, HTML, Notion, or raw text. Layout and structure are preserved.

02

Parse & split

Layout-aware segmentation feeds semantic boundary detection. Parent and child chunks are linked automatically.

03

Visualize

Inspect boundaries, metadata, and embedding distribution in real time. Diff strategies before you commit.

04

Retrieve

Export chunked corpora to your vector store. Replay queries and watch retrieval quality climb.

Where it shines

Built for the teams who can't afford bad retrieval.

From enterprise knowledge bases to research search, CHUNKZA fits wherever the quality of the answer depends on the quality of the chunk.

Enterprise KBUse case

Enterprise knowledge bases

Unify PDFs, wikis, Slack threads, and Confluence under one chunking policy. Engineers ship faster; domain experts trust the answers.

  • 10M+ pages supported
  • Role-aware metadata
  • Source-grounded citations
Read the scenario
RAG copilotsUse case

Domain-specific copilots

Build copilots that actually understand your product docs. Parent-child retrieval returns coherent context windows, not fragments.

  • Coherent context windows
  • Fewer hallucinations
  • Per-section recall tuning
Read the scenario
ResearchUse case

Research & academic search

Chunk long papers by section and citation. Retrieve claims with their supporting methods and figures attached.

  • Section-aware splits
  • Figure & table retention
  • Citation graph metadata
Read the scenario
SupportUse case

Customer support retrieval

Surface the right article snippet — not the whole FAQ. Overlap-aware chunking keeps multi-step guides intact end to end.

  • Guides stay intact
  • Ticket-aware routing
  • Live policy sync

By the numbers

Retrieval quality, measured at the chunk.

CHUNKZA is benchmarked continuously against the chunking strategies most teams still ship by default. The gap is not subtle.
