In the rapidly evolving world of AI-powered document processing, a new player called Extend has emerged with bold claims about revolutionizing how companies handle complex documents. While the company promises to transform messy paperwork into structured data with over 99% accuracy, the developer community has raised important questions about pricing transparency, performance benchmarks, and whether this represents genuine innovation or just another entry in an increasingly crowded market.

The Pricing Puzzle That Confused Developers
One of the most immediate concerns from the community centered around Extend's pricing structure, which multiple users described as confusing and overly complex. The company offers two processing modes—performance optimized and cost optimized—with different credit consumption rates and pricing tiers. This multi-dimensional approach left developers scratching their heads about how to accurately budget for their document processing needs.
This is the most confusing pricing page I've ever seen - different options have different credit usage and different cost per credits? How many degrees of freedom do you real need to represent API cost.
The company's CEO explained that this granular approach allows customers to mix and match processing modes based on their specific needs, such as using cheaper classification alongside more expensive extraction. However, the community response suggests that this flexibility comes at the cost of clarity, raising questions about whether simpler pricing models might better serve developers trying to integrate these services into their applications.
Accuracy Claims and the Benchmarking Question
Extend's marketing materials prominently feature accuracy rates >99% compared to ~80% for alternative solutions, but community members immediately questioned whether these claims had been validated against open benchmarks. One developer specifically asked if the company had tested its pipeline against OmniDocBench, an open benchmark for document processing systems.
The response revealed an interesting approach to accuracy measurement. Rather than relying solely on public benchmarks, Extend provides customers with internal evaluation tools to measure performance on their specific document types and use cases. The company recently added support for LLM-as-a-judge and semantic similarity checks, acknowledging that internal benchmarks alone aren't always representative of customer situations. This approach highlights the challenge of creating universal benchmarks in a field where document types and quality vary dramatically across industries and use cases.
Technical Innovations in Handling Complex Documents
The community discussion revealed several technical innovations that set Extend apart from traditional OCR solutions. For handling messy handwriting—a notoriously difficult problem in document processing—the company has developed an agentic OCR correction layer that uses Vision Language Models to review and correct low-confidence OCR errors. This represents a significant advancement over traditional rule-based correction systems.
Table processing presents another major challenge, and Extend's approach includes semantic chunking that detects table boundaries across multiple pages and table-to-HTML conversion for complex nested cells that standard markdown can't properly represent. These technical details emerged through community questioning rather than the original marketing materials, suggesting that the most interesting innovations often surface through developer dialogue rather than corporate messaging.
The Crowded AI Document Processing Landscape
Several commenters noted the proliferation of AI-powered document processing startups, questioning whether Extend represents genuine innovation or simply another entry in a saturated market. The company's CEO acknowledged the competitive landscape but argued that recent AI advancements have expanded the total addressable market by multiple orders of magnitude.
According to the company's perspective, 90% of the use cases they now tackle weren't technically solvable until about 12 months ago, representing mostly greenfield opportunities rather than replacement of existing solutions. This suggests we're witnessing a fundamental shift in what's possible with document processing, driven by recent advances in foundation models and multimodal AI systems.
Real-World Implementation and Use Cases
The discussion revealed diverse implementation patterns among Extend's customers. Some companies use the APIs to power real-time user-facing document upload flows, while others integrate them into agent systems or back-office automation tools. The flexibility to support multiple integration patterns appears to be a key value proposition, though it also contributes to the pricing complexity that confused some community members.
One long-term user commented on their positive experience, noting they'd been using Extend for over a year and were super happy with the product and accuracy of the data extraction. This type of organic endorsement carries significant weight in technical communities where developers are often skeptical of marketing claims and prefer peer validation.
The Future of Document Processing
As the conversation unfolded, it became clear that document processing is evolving from simple text extraction to sophisticated understanding of document structure, intent, and context. The community's questions about handwriting recognition, table parsing, and accuracy verification reflect growing expectations for AI systems that can handle the messy reality of real-world documents rather than just idealized forms.
The ongoing dialogue between Extend's team and the developer community demonstrates how technical products evolve through user feedback and scrutiny. While the company's ambitious claims initially drew skepticism, the detailed technical responses provided valuable insights into the current state of document processing technology and where it might be headed next.
The document processing revolution appears to be just beginning, with companies like Extend pushing the boundaries of what's possible. However, as the community discussion revealed, success in this space requires not just technical innovation but also clear communication, transparent pricing, and willingness to engage with skeptical developers who ultimately determine which solutions gain traction in the market.
