Precise document extraction for your agents — zero retention
What it does
Accurate document parsing for high quality outputs. Upload any file — PDFs, legacy Word docs, scanned, multilingual, handwritten, chart-heavy and get clean text out — no single word silently dropped — so your pipelines don’t break when models or policies change. We extract and normalise all your files data so you can plug it straight into OpenClaw or any other agent, LLM or pipeline. Zero data retention. Encrypted in transit and at rest. Use open-source or hosted.

Hi HackerNews, Lately, I have seen an explosion in posts offering paid APIs/services to get unstructured data into LLMs (i.e. langchain extract, ragflow, unstructured, unstract, just to name a few) and I have been largely disappointed by them, either because they fail to implement multimodal support, fail to give good context for "really tricky" PDFs / Word docs / Powerpoints, or are just plain difficult to use. In light of all these posts I figured I'd share my solution that has been working smoothly for me and my clients. I put it up on GitHub for free so you can check it…
- DTDocsRouter – The OpenRouter for OCR and Vision ModelsDec 2025 · docsrouter.com · ▲14
Most products that touch PDFs or images quietly rebuild the same thing: a hacked-together “router” that picks which OCR/vision API to call, normalizes the responses, and prays the bill is sane at the end of the month. DocsRouter is that layer as a product: one stable API that talks to multiple OCR engines and vision LLMs, lets you route per document based on cost/quality/latency, and gives you normalized outputs (text, tables, fields) so your app doesn’t care which provider was used. It’s meant for teams doing serious stuff with documents: invoices/receipts, contracts,…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
