Captioni โ The AI Captions Generator for Social Creators
Captioni is an AI-powered tool designed for Instagram, TikTok, and OnlyFans creators who want to grow their audience and boost engagement without wasting hours thinking of what to post.

Captions that match your vibe (Barbie, Edgy, Glamour, Baddie, Innocent, Funny).
Hashtags that help your content reach new audiences.
Bios that make your profile stand out.
DMs & Stories that spark conversations and conversions.
Whether youโre posting a fashion photo, a funny meme, or an OnlyFans teaser, Captioni creates short, catchy, and natural text that feels authentic โ not robotic.

Made for mobile: Optimized for on-the-go creators.
Affordable: Free plan included, Pro at only $29/month (vs. $99+ for big AI tools).

Braintrust focuses on evaluation-driven development: the idea that monitoring LLM applications means continuously scoring outputs against quality criteria, not just tracking latency and error rates. It's an eval platform first, with observability features built on top of the evaluation infrastructure. - Source: dev.to / 2 months ago
You're monitoring production traffic. You need Langfuse / Phoenix / Helicone / Braintrust for that. Online eval is a different problem class: implicit feedback, drift detection, hallucination rates on your data, not on HellaSwag. - Source: dev.to / 2 months ago
Same approach works with Langfuse, Phoenix, Braintrust, or your existing OTel pipeline โ the metadata.userId pattern is the universal part. - Source: dev.to / 3 months ago
