I hate capitalism, show me the open source repo instead.Advanced Chunking Strategies
Don't settle for simple text splitting. Choose from multiple strategies including Fixed Size, Paragraph, Heading-based, and Semantic chunking. Fine-tune parameters like window size and overlap to optimize for your specific LLM context window.
- Semantic similarity grouping
- Structure-aware splitting
- Real-time preview
Deep Metadata Enrichment
Make your chunks retrieval-ready. Automatically generate summaries, extract keywords, and apply custom metadata schemas. Define typed fields (text, number, array, json) to structure your unstructured data effectively.
- AI-generated summaries
- Keyword extraction
- Custom JSON schemas
- Tag management
Interactive Document Overlay
Trust but verify. Our visual overlay system maps chunks directly back to the original PDF, showing you exactly where each piece of text comes from. Identify missing context or poor splits instantly.
- Visual chunk mapping

During Trial vs After Subscription
Don't hate me for charging — it's also open source
I get it. You'd rather run your own infrastructure than pay monthly fees. That's why ChunkForge is fully open source. Self-host it on Docker with a single command and keep your data (and your wallet) under your control.

I don't deserve to live in an apartment anyway - the streets are where I belong and where I shall return.
Trusted by a few OG's in the RAG space
(I'm working on it, okay?)
Look, I could put a bunch of fake company logos and testimonials here like every other SaaS landing page. But here's the thing: I hate liars, and this is a bootstrapped project, largely to solve problems I've had with context retrieval. I'd rather be honest about being new than pretend we're already powering every other Fortune 500 company.
