Independent tool studio
Machined for precision.
Human accountability.
We build instruments you own. They start every time, do one job well, and keep your work on your device. No subscription for core tools.
ShadowRig is not a cloud converter company and not a hype AI brand. It is a studio that ships precision instruments for real work: files, cars, and parts.
Lean team
Small crew. Feedback goes to the people who ship the code.
Local when we can
Files and on-device AI run in your browser. We do not upload your content to process it.
Tools you keep
Fewer products, more care per unit. When we charge, direction is one-time purchase, not a seat tax.
Private file workspace
PDF and file jobs without the upload.
Toolkit is the product you open when you need to merge PDFs, split pages, compress a video, convert a photo, or pull text from a scan. It feels like the familiar online PDF sites, with one hard rule: the file stays on your machine. Drop something in, pick an action, download the result. Light on-device AI is there when you need it for OCR, captions, or a quick rewrite. No account for core jobs.
Who it's for
Anyone who handles contracts, scans, photos, or media and does not want a random website to keep a copy. Builders and small teams who need a dependable local converter, not another SaaS login.
What people use it for
- Merge three PDFs into one before you send a packet
- Compress a phone video so it fits an email
- OCR a screenshot and copy the text
- Strip EXIF from photos before you share them
Automobile performance instruments
A state-of-the-art phone dyno for the road.
Caliper turns the phone in your pocket into a performance instrument for cars and bikes. RoadDyno estimates on-road power and lets you compare runs after a mod. Drag Timer catches 0–60 and beyond with GPS launch logic. Smooth Drive grades how cleanly you drive. Noise Doctor and related mic tools help you chase belt squeal, exhaust tone, and cabin drone without uploading a recording to the cloud. Built for the driveway, the road, and the track day, not for a telematics subscription.
Who it's for
Enthusiasts, tuners, and serious drivers who want dyno-style feedback and sound diagnosis on real roads. People who already live with a phone on the dash and refuse to send every run to someone else's server.
What people use it for
- Pull a RoadDyno curve after an intake or ECU flash
- Time a clean 0–60 on an open stretch
- A/B exhaust tone before and after a muffler
- Log runs offline and compare them later

Companion for mechanical engineers
Open the part. Measure. Move on.
Vernier is built for mechanical (and adjacent electrical) work when you do not want to fire up a full CAD or EDA seat for a one-minute check. Open a STEP or STL, section it, measure. Peek a Gerber layer. Calibrate a drawing photo and take a dimension. Build a BOM or cut list. Pull tap drills, fits, and wire gauges from shop charts. Jobs keep files and notes together. Everything stays local so a customer drawing does not need to leave your laptop.
Who it's for
Mechanical engineers, buyers, machinists, and makers who receive CAD and drawings every day. Reviewers who need a quick check before the heavyweight tool. Students and hobby EE work that still needs honest dimensions and board peeks.
What people use it for
- Open a vendor STEP and confirm overall size
- Peek a Gerber outline before fab
- Measure a feature on a phone photo of a print
- Export a cut list CSV for the shop

How we build
Open a product above when you are ready. The catalogs and instruments live inside each app, not as a long list on this page.
We avoid cloud inference that holds your content, subscription walls on basic utilities, and manifesto fluff. Spec-like copy. Honest limits. Instruments that earn their place.
