Show HN: Concat: the open-source CapCut replacement.
Concat, an open-source CapCut replacement built in ~3 weeks using Claude (Fable 5.1), runs all AI features locally and includes MCP support plus a decentralized asset system for Filters, Effects, and Templates, allowing users to create, share, or sell custom assets. It was created in response to CapCut paywalling features after acquiring millions of installs and users.

score
score 8 out of 10. 0-10: how dense the facts are, multiplied by how much you can do with them after reading. 8+ means the topic's evidence bar is met: benchmarks and availability for a new model, amount and investors for a funding round, revenue figures for a solo-money story. Below 5 an item does not enter the digest. A press release scores 3 or less, a reprint loses 2, anything older than 14 days loses 1, a headline that misleads loses 3.
