Adam

Adam's core bet is that hardware engineers don't want another chat box — they want the artifact. Every worked example on its site ends in something you can hand off: a boss wall thinned to 1.6 mm with a gusset rib and 1.0° draft toward the A-side with the drawing dims updated to match; a 47-line-item BOM with six WIP revs flagged, a gasket referencing rev B against a released rev C, two duplicate screws consolidated to a McMaster part number, released items pushed to Arena; a baseplate drawing with H7 fits, Ø0.05 true position on the dowel bores and an over-constrained dimension chain rebased from datum B; an RFQ to two sheet-metal shops with rev C STEP, flat-pattern DXF, 5052-H32 at 2.0 mm, 8 bends and clear chromate per MIL-DTL-5541 Type II Class 3 — with your target price deliberately left out so you don't anchor the shops. That specificity is the product's selling point and, from the scrape, it's backed by real workflow plumbing rather than prompt gymnastics. The 2026 changelog is where the substantive engineering shows. Adam can now create and edit assembly mates and relations inside Onshape, including suppressing and unsuppressing mates; the connector catalog picked up GPT-6-Astra; model choices are organized into Lite, Pro and Ultra families with live model names and reasoning-effort controls; Rhino 8 landed as a built-in desktop connector preset with its plug-in and MCP server bundled. There is an MCP layer and a beta API, which matters if you want Adam inside your own tooling rather than only inside its UI. Browser notifications when a task finishes, toasts when a chat is waiting on an approval, and streaming follow-up messages during a run all address the practical problem with long-running CAD agents — you can't babysit a tab. Strengths: it edits rather than advises; it works on your connected stack with no exported copies of your IP; the integrations list covers the real hardware toolchain (Onshape, Fusion, SolidWorks, Arena, McMaster-Carr, Digi-Key, Xometry, Google Drive, Google Sheets, Jira, Linear, Notion, Airtable, Slack, Gmail); and renders, CMF direction with pantone codes, and vendor email drafting are bundled rather than bolted on as separate subscriptions. Weaknesses and honest limits: stack dependency is the big one. Onshape, Fusion, SolidWorks and now Rhino cover a lot of mechanical work but not all of it, and PLM support leans on Arena. PCB and EDA work is out of scope. Pure 2D drafting with no 3D geometry has nothing for Adam to work against. Some workflows still require you to accept changes inside the connected CAD application, and while oversized attachments are auto-sized so they don't break a turn, extremely large uploads remain a risk. Nothing in the scrape documents on-prem or offline operation — this is a cloud product and the docs assume an internet connection. Where it fits: a mechanical engineer who spends Friday afternoons on BOM cleanup, drawing dims and RFQ emails. A hardware startup that needs sourcing
