Daily AI-generated crypto signals

CryptoSignalOwn product2026

A freemium SaaS platform that analyses the crypto market with AI every day and sends users a clear signal — Buy, Wait, or Accumulate — directly to their email or Telegram, at the time they choose and in the language they speak.

The challenge

The market never sleeps.
People do.

Crypto markets operate 24 hours a day, 7 days a week. News hits at midnight, prices move 20% in hours. Most retail investors — both curious beginners and experienced traders — face the same problem: they don't have the time, the tools, or the expertise to follow the market consistently every day.

Most existing options had the same limitations: generic newsletters covering the overall market (not the coins you actually follow), technical analysis tools built for experienced traders, or Telegram signal groups of questionable credibility. None of them arrived at your time, in your language, for your specific coins — automatically and without an expensive subscription.

CryptoSignal was built to fill that specific gap.

The solution

An end-to-end automated pipeline

An n8n workflow that fires every hour, checks which users have a signal scheduled, fetches real market data, generates the analysis with AI, and delivers it — no manual work, at any hour of the day.

Key features

What the platform includes

01

Live charts dashboard

n8n pipeline that fires on each user's schedule and timezone. Fetches real CoinGecko data, builds a market-context prompt, and calls Claude Haiku to generate the signal. Includes automatic retry on model overload errors.
