Building an ai email operator in public. In email since 2013. Shipped during evenings because I love F1, zero patience for vanity open rates.

[denaskul @denaskulinicius]

i do email marketing for a living - not frontend.

so i built this instead: tap any part of a 2026 f1 car and it tells you how it works, what it costs, and why races are won by it.

13 parts. built on nights because i love the sport. €12–20M of machine that weighs 768kg.

what should i break down next?

@ariell_xyz see my bio

[denaskul @denaskulinicius]

drop what you're building. i want to see what this corner of x is shipping.

=> Firebase

@SaraDiscovers don't listen to the noise, although gpt 5.6 limits are very friendly compared to fable 5, good luck running out of them on max plan before reset hits.

[denaskul @denaskulinicius]

@Amank1412 unlikely imo

We've just added several new features to Claude Managed Agents.

You can now configure effort levels per agent, seed sessions with events, add up to 500 skills per session, use webhooks for environments + memory stores, and stream events for sub-agents.

@copywriter_adam people are too lazy nowadays

[denaskul @denaskulinicius]

before AI: 2 hours to build an email flow.
after AI: 2 hours arguing with the AI, then building it myself.

Reply with your landing page. We'll give honest feedback.

[denaskul @denaskulinicius]

@mytwillot nice, how you're different than others?

[denaskul @denaskulinicius]

honest one for founders:

did you validate before building or build first and hope?

[denaskul @denaskulinicius]

confession. i had code running for a week before i could clearly say what the value prop even was

that’s backwards and i knew it while doing it. building got so cheap it’s now easier to ship than to think

the bottleneck moved. it’s not “can you build it.” it’s “should this exist”

[denaskul @denaskulinicius]

@MaxHirsch13 I don't like it, vercel + supabase it's too common, personally I prefer any vps, hostinger, hetzner, namecheap etc. There's also https://t.co/q75T0t166s

"Gemini 3.6 Flash is the exact same model as 3.5 Flash"

Same Intelligence Index - 50 and 50. Sure.

Hallucination rate:
3.5 Flash - 61%
3.6 Flash - 54%

Same intelligence, meaningfully less confident nonsense.

Everyone benchmarked the wrong axis and called it a flop.
