ClearHandoff

What it does

Mechanical engineers spend hours on repetitive drawing checks. Costly mistakes sometimes still reach production. ClearHandoff's AI drawing review is your second pair of eyes. A professional checker that's always on, never tired, never overloaded. It flags missing dimensions, tolerances, and manufacturing issues -- plus any rules you specify, like DFM constraints for your machines or your design guidelines. Pin comments, discuss in threads, share with suppliers. Faster reviews, fewer errors.

Review and approve engineering drawings with your team. AI catches missing tolerances and errors before production. Hand off with confidence.

Faster reviews, fewer errors. One place for your team to collaborate on drawings and hand them off. AI feedback in minutes. Free to start, no credit card needed. Drop a PDF or DXF from any CAD system. Your file stays private and secure. AI flags missing specs, inconsistencies, and manufacturing problems — in minutes. Pin comments, track what's resolved. Everyone — team and suppliers — reviews in one place. As a mechanical engineer, I've designed parts, created engineering drawings, taught drawing standards at university, and worked with manufacturers. I built ClearHandoff because I know how much gets lost between 'done' and 'delivered.' AI reviews at just €2.00 €1.60 each. Bigger plans for…from clearhandoff.com

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  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…
