What it does
Change a table, a paragraph, a layout and the whole document reflows — columns resize, content shifts, page breaks adjust. Every export stays editable forever via embedded source, and comes out Tagged and PDF/UA‑1 — with PDF/A‑3a archival or the PDF/UA‑2 second edition one toggle away. Validated in veraPDF, zero failures. No sign-up to try · Don't trust us? Download a sample below and run it through veraPDF yourself Most editors overlay text on a frozen page. ReflowPDF restructures the entire document. See the difference: Most HTML-to-PDF tools output untagged files a screen reader can't read.

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
