Tech Feed Bot (n8n: RSS to Telegram, ek line mein)

Tech news ke liye roz dus sites kholna, scroll karna, aur phir bhi kuch yaad na rehna. Is guide mein ek chhota n8n workflow hai: tumhari pasand ki site ka RSS feed har ghante check hota hai, nayi post aate hi Gemini usse ek line ka Hinglish summary banata hai, aur wo line article ke link ke saath Telegram par aa jaati hai. Neeche starter workflow ka JSON hai (download bhi kar sakte ho), aur har node ki baat n8n ke apne docs ke hisaab se.

Reel mein jo post ('Nayi open-source laptop battery tool launch'), uska ek line summary aur Telegram message dikha, wo banaya hua example hai: koi asli site ya product nahi, kisi run ka output nahi. Feed URL bhi placeholder hai (example.com), apni site ka daalna.

Node by node (n8n ke official docs ke hisaab se)

Kya chahiye

• Site ka RSS feed URL: jo site khud publish karti hai (aksar /feed, /rss ya /feed.xml par, ya page ke footer mein RSS icon). Jis site ka feed nahi hai, use scrape mat karo.
• n8n: apne server par self-host (Community Edition) ya n8n Cloud (free trial). Kharche ka section neeche hai. Trigger har ghante chalega, to n8n chalta rehna chahiye.
• Telegram bot ka token (BotFather se) aur apna Chat ID.
• Google AI Studio ki Gemini API key (free quota ke terms neeche padho).

Gemini API key jodna (n8n docs ke hisaab se)

1. n8n ke docs ke hisaab se Google AI Studio ke API Key page par jao (aistudio.google.com/apikey) aur 'Create API Key' dabao. Naya project chuno ya banao.
2. Key copy karo. n8n mein Credentials > Add > 'Google Gemini(PaLM) Api' chuno, key paste karo, save karo.
3. Gemini Model node kholo, ye credential chuno, model dropdown se ek chat model chuno.
4. Key kisi ko mat bhejo, screenshot mein mat dikhao. Leak ho jaye to AI Studio se delete karke nayi banao.

Telegram bot aur Chat ID (n8n docs ke hisaab se)

1. Telegram mein BotFather kholo, /newbot bhejo, naam do, phir ek username jo 'bot' par khatam ho. BotFather token dega.
2. n8n mein Credentials > Add > Telegram API, Access Token mein wo token daalo.
3. Chat ID: sabse aasan, ek Telegram Trigger node lagao, bot ko ek message bhejo, trigger ke output mein chat.id dikhega. Ya @RawDataBot ko message karke apna id dekho. Group ke liye web Telegram ke URL mein group number (minus ke saath) hota hai.
4. Send Update node ke Chat ID mein wo number daalo. Bot ko pehle /start bhejna zaroori hai, warna bot tumhe message nahi kar sakta.

Step by step

1. n8n kholo (Cloud trial ya apna self-host) aur ek naya workflow banao.
2. Neeche wala starter workflow Import from File se laao (download button upar hai), ya JSON copy karke canvas par paste karo.
3. New Post node mein Feed URL apni site ka daalo.
4. Gemini Model node mein apna credential chuno; Send Update mein Telegram credential aur Chat ID.
5. Workflow ko ek baar test karo: trigger node par 'Fetch Test Event' ya 'Test step' dabao, feed ki latest item aayegi, aage ke nodes chala ke dekho Telegram par line aayi ya nahi.
6. Sab theek, to Save aur Publish (activate) karo. Polling trigger tabhi chalta hai jab workflow active ho.

    "Gemini Model": {"ai_languageModel": [[{"node": "One Line Summary", "type": "ai_languageModel", "index": 0}]]}
  }
}

Is JSON mein credentials nahi hain. Feed URL placeholder hai aur Chat ID khali hai: dono tumhe bharne hain. One Line Summary ka prompt aur Send Update ka text hamari design hai, apne hisaab se badlo.

RSS feed kahan milta hai

• Site ke URL ke aage /feed, /rss, /feed.xml ya /atom.xml laga ke dekho; bahut si blog sites par inme se koi ek khulta hai (XML dikhega).
• Page ke footer ya header mein RSS icon dhoondo.
• Jo feed khule, wahi URL New Post node mein daalo. Browser mein khol ke ek baar dekh lo ki items aa rahi hain.
• Feed nahi hai to ye bot us site ke liye nahi hai. Bina feed wali site ko scrape karna is guide ka hissa nahi.

Summary AI ki hai, galat ho sakti hai

Google ke Gemini API terms kehte hain: 'The Services include experimental technology and may sometimes provide inaccurate or offensive content' aur 'Use discretion before relying on ... content provided by the Services.' Isliye hamara prompt kehta hai 'use only what the text says, add nothing', aur message ke saath hamesha article ka link jaata hai.

1. Summary ko headline samjho, khabar nahi. Jo cheez important lage, link se poora article padho.
2. Kisi ko aage bhejo to apni ek line ke saath source ka link aur naam do. Poora article copy karke dobara post mat karo: wo site ka content hai.
3. Agar summary baar baar galat lage, to prompt mein 'max 25 words' ki jagah thoda bada summary maango, ya sirf title bhejo.

Free Gemini quota aur privacy

Google ke Gemini API terms ke hisaab se: 'When you use Unpaid Services, including, for example, Google AI Studio and the unpaid quota on Gemini API, Google uses the content you submit to the Services and any generated responses to provide, improve, and develop Google products and services', aur 'Do not submit sensitive, confidential, or personal information to the Unpaid Services.'

• Is workflow mein sirf public article ka title aur snippet jaata hai, jo waise bhi internet par khula hai. Isliye risk kam hai.
• Private feed (company ka internal feed, paid newsletter ka personal feed, koi feed jisme tumhara naam/email token ho) is workflow mein mat jodo.
• Busy feed par Gemini ke free rate limits lag sakte hain: har ghante poll karo, har minute nahi. Ek ghante mein das posts aayi to das AI calls hongi, itna theek hai.

Aam galtiyan

• Workflow publish (activate) nahi kiya. Polling trigger sirf active workflow mein chalta hai; test mode mein wo bas ek baar fetch karta hai.
• Feed URL ki jagah site ka homepage daal diya. Node ko XML feed chahiye, HTML page nahi.
• Bot ko /start nahi bheja, to Telegram bot tumhe message nahi kar sakta.
• Chat ID galat: Telegram Trigger se nikaalo, andaaze se mat likho.
• Pehli baar bahut saari purani posts aa gayi: pehla poll feed ki latest item se shuru hota hai; agar baadh aaye to Every Hour ki jagah pehle ek test chalao aur dekho.
