Digestbot

Personal Telegram bot that sends a daily digest combining weather and news.

Digest contents

• Weather — today's forecast (temperature range, precipitation, conditions) from Open-Meteo
• Irish Times — top 3 stories from the Irish Times RSS feed, selected and summarized by an LLM
• Meduza — top 3 stories from the Meduza RSS feed, selected and summarized in Russian by an LLM

Prerequisites

• Go 1.26+
• A Telegram bot token (from @BotFather)
• The chat ID where the bot should send messages (send a message to your bot, then visit https://api.telegram.org/bot<YOUR_TOKEN>/getUpdates — the chat ID is in result[].message.chat.id)
• An OpenAI API key (from platform.openai.com)

Configuration

All configuration is done via environment variables or CLI flags. Flags take precedence over environment variables.

Setting	Env var	Flag	Required	Default
Telegram bot token	DIGESTBOT_BOT_TOKEN	--bot-token	yes	—

Latitude and longitude are used to fetch weather from Open-Meteo. Timezone must be a valid tz database name (e.g. Europe/Dublin, America/New_York).
