Show HN: Sidecar – AI Social Manager (Analyzes past hits to write new posts) Hi HN, I built Sidecar ( https://sidecar.bz ) because I was having issues maintaining a social media presence for my last startup. I would spend a lot of time trying to create content, but I often froze up or burned out, and the marketing died. How it works: Instead of guessing what to write, Sidecar connects to your existing accounts (Threads, Bluesky, Mastodon, Facebook, Instagram) and analyzes your past posts to see what actually worked. It uses that data to generate weeks of new, text-based content that mimics your successful posts, which you can then bulk schedule in one go. I’d love to hear what you think of Sidecar. You can use code HNLAUNCH for a free month if you want to test the ai features. https://ift.tt/Pe8E7SG January 13, 2026 at 12:18AM

Show HN: AI in SolidWorks https://ift.tt/1dvWjTl

Show HN: AI in SolidWorks Hey HN! We’re Will and Jorge, and we’ve built LAD (Language-Aided Design), a SolidWorks add-in that uses LLMs to create sketches, features, assemblies, and macros from conversational inputs ( https://www.trylad.com/ ). We come from software engineering backgrounds where tools like Claude Code and Cursor have come to dominate, but when poking around CAD systems a few months back we realized there's no way to go from a text prompt input to a modeling output in any of the major CAD systems. In our testing, the LLMs aren't as good at making 3D objects as they are are writing code, but we think they'll get a lot better in the upcoming months and years. To bridge this gap, we've created LAD, an add-in in SolidWorks to turn conversational input and uploaded documents/images into parts, assemblies, and macros. It includes: - Dozens of tools the LLM can call to create sketches, features, and other objects in parts. - Assembly tools the LLM can call to t...

Show HN: Pane – An agent that edits spreadsheets https://ift.tt/O5hEu4f

Show HN: Pane – An agent that edits spreadsheets Hi HN, I built Pane, a spreadsheet-native agent that operates directly on the grid (cells, formulas, references, ranges) instead of treating spreadsheets as text. Most spreadsheet AI tools fail because they: - hallucinate formulas - lose context across edits - can't reliably modify existing models Pane runs inside the spreadsheet environment and uses the same primitives a human would: selecting cells, editing formulas, inserting ranges, reconciling tables. I launched it on Product Hunt this weekend and it unexpectedly resonated, which made me curious whether this approach actually holds up under scrutiny. I'd love feedback on: - obvious failure modes you expect - whether this is fundamentally better than scripts + formulas + copilots Happy to answer technical questions. https://paneapp.com January 12, 2026 at 10:41PM

Show HN: words.zip – Massively infinite word search https://ift.tt/PgOKuwH

Show HN: words.zip – Massively infinite word search Hi HN! This is a word search game I launched in the beginning of this year - didn't get much traction then, but it's been posted around a bit (right now getting some traffic from kottke.org) and now has over 12,000 words found! Now that it's a little more filled out I figured I'd share it again. Really enjoying seeing what everyone is making on it - it appears most people start by just adding a few words to the big clump in the middle, then adding to other people's projects (or ruining them) and finally working on their own little concepts. My favorite is the kitty to the north. Hope you enjoy! https://words.zip/ January 12, 2026 at 09:22PM

Show HN: Persistent Memory for Claude Code (MCP) https://ift.tt/h4ER9Ht

Show HN: Persistent Memory for Claude Code (MCP) This is my attempt in building a memory that evolves and persist for claude code. My approach is inspired from Zettelkasten method, memories are atomic, connected and dynamic. Existing memories can evolve based on newer memories. In the background it uses LLM to handle linking and evolution. I have only used it with claude code so far, it works well with me but still early stage, so rough edges likely. I'm planning to extend it to other coding agents as I use several different agents during development. Looking for feedbacks! https://ift.tt/SUAcfVI January 11, 2026 at 03:34AM
