what it is
OwlCAD is a parametric 3D modeler that runs in a browser tab, built for 3D printing. It fills the gap between Tinkercad, which most people outgrow, and Fusion 360 or Onshape, which mean an install, an account and a learning curve. **Parametric, so nothing is baked in.** A dimension you set on day one is still editable on day thirty, and changing it rebuilds the model instead of making you redo the work. Booleans are manifold by construction, so exports don't carry the stray geometry that makes a slicer complain. **It knows about 3D printing.** Clearance presets for press, slip and loose fits size holes and slots correctly for FDM. A print check flags overhangs and thin walls and tells you whether the mesh is watertight before you export. It will also hollow a solid, lay it flat and estimate print weight and cost. **Real modeling tools.** Sketches with constraints, per-edge fillets and chamfers, patterns, sweep and loft, and assemblies with mates, a bill of materials and an exploded view. 36 generators cover the parts nobody wants to model by hand: gears, threads, enclosures, Gridfinity bins, bearings, hinges, springs and fans. **Scripting if you want it.** OwlCAD opens and runs OpenSCAD files, with a live script editor and customizer parameters. **Files.** Opens STL, 3MF, OBJ, GLB, STEP, SVG, DXF, OpenSCAD and images. Exports STL, 3MF, OBJ, GLB, STEP, SVG and DXF. **Pricing.** The editor is free and needs no account to start. Projects are private by default, and you keep full commercial rights on every plan, Free included. Pro is $12/month or $120/year and adds AI generation from text or an image, with 20 credits a month, Modify with AI, and AI agent access over MCP from Claude, ChatGPT or Cursor. Bring your own provider key and generation costs no credits. One-time credit packs are $5, $8 and $15 and never expire. **Classrooms.** Free, with pseudonymous student accounts, teacher controls and a signable district data agreement.

what it is
ProofSnap preserves web pages, chats and files as forensic evidence packages that anyone can verify independently. It is built for lawyers, investigators and journalists, and for teams that need evidence capture inside their own tools. Each capture contains a full-page screenshot, the page HTML, the page text, metadata, a chain of custody record and a tamper-evident forensic log. Every file is SHA-256 hashed and the manifest is RSA-signed to protect integrity. The package also records NTP-verified time, DNS, WHOIS and HTTP header data, with C2PA Content Credentials on the screenshot. Depending on the plan, packages are anchored with an OpenTimestamps Bitcoin proof and an eIDAS qualified timestamp from Disig a.s., a Qualified Trust Service Provider on the EU Trusted List. ProofSnap is available as a Chrome extension and as an API. Its remote MCP server at https://mcp.getproofsnap.com/mcp connects to Claude, ChatGPT, GitHub Copilot, Cursor and other AI assistants, with OAuth sign-in and nothing to install. It also includes monitoring of watched pages, matter folders and a public verifier.
