Magwell
Know what you have. Compose what matters.
Magwell turns your parts bin into purposeful builds — with ballistics, an optics wiki, and AI that runs on our own metal, not big tech's.
or $9/mo · Track your bin for free. The AI build suggestions, ballistics, and the on-our-metal sovereignty layer are the paid add-on — you pay for the tool so you never become the product.
Free core · cancel anytime · encrypted, never a registry, export anytime.
Your founding rate is locked for life — as long as you stay a member.
Only 100 founding spots — once they're gone, they're gone.
Made by one of us — a builder in this community, not a company.
What you get
- See every lower, upper, BCG, barrel, and optic you own — so you stop buying the third one you forgot was in a drawer.
- Compose builds by role — a 300 BLK carbine, a hunting rifle, a truck gun — from parts already on your bench.
- Ask the AI what to build next, and it answers from your actual inventory, not generic forum noise.
- Settle red dot vs. LPVO vs. EOTech with an optics wiki written for builders, not marketers.
- Pull real ballistic data into every decision, so the round drives the build — not the other way around.

Questions
Is this a registry? Who can see my inventory?
No. It's encrypted at rest and unlocked only on your login; there's nothing central to subpoena and nothing aggregated to breach. We can't read it, won't sell it, and no third party can pull it.
Why not just use a spreadsheet?
A spreadsheet stores rows. It can't tell you a spare upper, a lower, and a drawered barrel compose into a complete 300 BLK carbine — the composition, ballistics, and optics layer is the thing it structurally can't be.
Where does the AI run?
On our own metal with local models — never OpenAI or any big-tech API, never trained on your data.
Why is the AI part paid?
Private compute costs real money; the core is free, the AI + sovereignty layer is the subscription, so the business never depends on ads or resale.
What if you shut down?
Full export anytime — hosted so you don't have to self-host, but never locked in.
