AI copilot for on-chain DeFi: message to send stablecoins, swap, bridge, monitor markets, execute workflows.
Nexis-AI · GitHub
NexBench NEXBENCH measures what an autonomous agent can actually do on-chain — execute transactions, route swaps, bridge funds, manage DeFi positions, research tokens, catch drainers, reconstruct portfolios, and run treasury governance — across 214 tasks in 8 categories, each run 5 times against deterministic forked-mainnet environments.

AI+Cloudflare 全家桶写了个漂流瓶网站,瓶子被捡起就消失 一直想做个能让人慢下来的小东西。朋友圈太像舞台,匿名树洞又太沉。后来想起小时候往海里扔瓶子的感觉,写完塞进去,漂到谁手里算谁。 于是有了这个:玩个漂流瓶,地址 https://qqdeni.com 玩法很简单:写下一句话扔进海里,别人随机捞到一个,点开看完瓶子就没了,只有你和他见过。没有点赞,也没有关注列表,它绕开了社交产品那一套,就是一张被海浪送走的纸条。 几个我自己较真的小地方: 1 、封面用十种牛逼闪闪的颜色随机分配,不显示上传图,画面干净些 2 、整体走清新简约路线,配色参考了纪念碑谷 3 、扔完会生成一个带小瓶 logo 的二维码,扫了就能把瓶子送到朋友那边 技术没多复杂,全在 Cloudflare 上跑,整站就一个 com 域名,还是之前买的闲置的。 做这个纯粹因为自己想玩,顺手分给也需要一点安静的人。路过愿意扔一个或者捡一个,我会很开心。配色、交互、文案哪里别扭都欢迎挑,我一直在改。 谢谢大家愿意看这一眼。

AI event organizer that builds event pages, sends invites, and books venues based on text descriptions.
u/MainNail9026 · Reddit
Killing Luma and Partiful in 2026 I built an AI co-host that actually does the event logistics, not just the invite page Every group chat I've been in dies the same way: five people say "we should do something," someone suggests a date, three people don't reply, and it's dead. Currently the tools that exist (Partiful, Luma) are great at making a pretty invite and then sending to an RSVP list. But the invite is the last 10% of the work. The other 90% is picking a place,
