🤖 What it does

Bluesk-AI is a bot that lives on Bluesky: you mention it and it replies. It reads what's happening in real time, interprets the question, and answers in natural Chilean Spanish. It is not a downloadable app — it runs entirely on the cloud, serverless.

🔎

Real-time multi-search

Weather, currency, news, earthquakes, holidays, crypto and more — from free public sources, no API keys.

🗣️

RAG with Chilean slang

A vector bank of 2,327 modismos and 7,496 phrases interprets your input and polishes every reply.

🧠

Dual AI with fallback

Mistral Nemo as the main model, llama 3.2 3B on Cloudflare Workers AI as automatic backup.

🧵

Thread replies

Up to 5 posts per reply, split by sentence, max 300 characters per post.

🕐

Scheduled posts

Good mornings, good nights and random phrases — all in Chilean time.

🌿

Ecological excuses

When the daily limit is reached, it answers with humorous environmental excuses.

🏗️ Architecture

Everything runs in a single Cloudflare Worker: the API, the mention polling, and the scheduler. There is no external bot server and no VPS.

🛡️ What it won't do

No opinions

Rejects subjective questions — it has no opinions on what you should do.

No images or documents

Doesn't analyze images, PDFs or long documents.

No deep analysis

Rejects research, thesis and complex analysis requests.

Never replies to itself

Its own mentions are always ignored.
