ReddGrow AI — get your brand cited by ChatGPT and Claude by showing up on Reddit first

Reddit threads are what ChatGPT, Claude, and Perplexity train on and cite in their answers. ReddGrow AI finds the right conversations, monitors brand mentions, helps post authentic responses, and tracks exactly how many times AI models are recommending your brand as a result. $17,091 last 30 days on TrustMRR — ₹14.4L/month, Stripe verified.

01 / HOW IT WORKS

What the app actually does

ReddGrow AI's insight is that ChatGPT, Claude, and Perplexity don't make things up — they cite what they found on Reddit, forums, and review sites. Brands that show up authentically in those conversations get recommended when people ask AI for product recommendations. Most brands have no idea this is happening, and zero strategy to influence it.

1

User connects their brand and defines their keywords

Brand name, product category, competitor names, and the problems their product solves. ReddGrow uses this to scan Reddit continuously for relevant conversations where the brand should be present.

2

AI finds relevant Reddit threads in real time

Threads where users are asking for recommendations, comparing tools, describing problems the brand solves — filtered by recency, upvotes, and how likely the thread is to be cited by AI models.

3

AI drafts an authentic community response for each thread

Not a promotional comment — a genuinely helpful response that answers the question and naturally mentions the brand where relevant. Written in Reddit tone, not marketing tone. User reviews and edits before posting.

4

AI tracks how often ChatGPT/Claude cite your Reddit content

The measurement layer: ask ChatGPT "what is the best tool for X" and track how often your brand appears in the answer. Before/after score. This is what makes the ROI of Reddit marketing visible for the first time.

02 / INDIA POTENTIAL

Does this work as an India play

India has thousands of B2B SaaS founders, agencies, and product companies trying to reach global audiences — particularly US ones. Reddit is one of the most powerful channels to build that reach, but Indian founders largely ignore it or use it wrong. A tool that teaches authentic Reddit marketing and tracks AI citation impact is something every Indian founder targeting US customers needs.

US traffic
Indian founders building for US audiences can use Reddit as their primary US traffic channel — showing up in r/SaaS, r/entrepreneur, and r/startups drives qualified US visitors who convert into paying customers.
Perplexity
Perplexity cites Reddit constantly — it is one of the top sources in Perplexity answers for product recommendations. Brands present in Reddit threads show up in Perplexity without any paid ads.
₹2,999/mo
Realistic India-priced entry tier — Indian SaaS founders and agencies targeting US audiences who spend ₹10,000-50,000/month on ads will happily pay ₹2,999 for a tool that gets them into AI-cited Reddit threads.
r/India angle
Indian B2B brands targeting domestic audiences can show up in r/IndiaBusiness, r/indianstartups, and r/india — subreddits with millions of members that Indian marketers completely underuse.
03 / THE WEEKEND BUILD

Friday to Sunday, hour by hour

Scope to three things for v1: Reddit thread discovery by keyword, brand mention monitoring, and AI citation tracking (ask ChatGPT/Perplexity if they mention the brand). The response drafting can be manual at first — the discovery and tracking are the core value.

Friday
Evening · 3 hrs
7–8 PM Set up Next.js + Supabase. Build the brand setup form — brand name, keywords, competitor names, problem the brand solves. These become the search terms for Reddit monitoring.
8–9 PM Integrate Reddit API (OAuth) or use Pushshift/RedditSearch API to search for threads containing the user's keywords. Return threads sorted by upvotes and recency, filtered to threads where the brand could add value.
9–10 PM Build the thread discovery dashboard — shows relevant threads with subreddit, upvotes, comment count, top comments preview, and a "Draft response" button for each.
Saturday
Full day · 7 hrs
Morning Build the AI response drafter — user clicks "Draft response" on any thread, Gemini API reads the thread context and generates an authentic, helpful community response that naturally mentions the brand only where relevant.
Afternoon Build the brand mention monitor — scheduled job checks Reddit every hour for new mentions of the brand name and competitor names. Alerts sent via email or WhatsApp. User sees sentiment (positive/negative/neutral) for each mention.
Evening Build the AI citation tracker — the core differentiator. Every morning at 9 AM, the system asks ChatGPT, Perplexity, and Claude "what is the best tool for [user's category]?" and records whether the brand was mentioned. Tracks the score over time.
Sunday
5 hrs
Morning Build the analytics dashboard — Reddit presence score (threads engaged, upvotes received), brand mention trend over time, and AI citation score (% of AI responses mentioning the brand vs competitors).
Afternoon Razorpay integration — Rs2,999/month Starter (5 keywords, 3 AI engines tracked, 50 thread alerts/month), Rs6,999/month Pro (unlimited keywords, daily AI citation checks, competitor tracking, response drafter).
Evening Test with your own brand — set up buildwithkanhaa as the test brand, run the thread discovery, draft one response, run the AI citation check. Record the demo.

05 / WHERE & HOW TO DEPLOY

Going live

Where: Vercel for the app, Supabase for database. Reddit API for thread discovery (free tier is sufficient to start). The AI citation tracking calls cost per API call — model this at your subscription price. One citation check across 3 engines costs roughly Rs1-2.

Push to GitHub, import into Vercel.
Create a Reddit Developer account and register an app at reddit.com/prefs/apps to get OAuth credentials.
Sign up for OpenAI API (for ChatGPT citation checks) and Perplexity API (for Perplexity citation checks).
Add env vars: SUPABASE_URL, SUPABASE_KEY, REDDIT_CLIENT_ID, REDDIT_SECRET, GEMINI_API_KEY, OPENAI_API_KEY, PERPLEXITY_API_KEY, RAZORPAY_KEY.
Set up a Vercel Cron job for hourly mention monitoring and daily citation checks.
06 / MARKETING & REVENUE

Getting paying users

How to market it

  • Post the demo reel: "I asked ChatGPT to recommend tools for [category] last month — my brand wasn't mentioned. I used ReddGrow for 30 days to show up authentically in Reddit conversations. I asked ChatGPT again. Here's what it said now." The before/after citation change is the entire hook.
  • Run 3-5 reels/day targeting Indian SaaS founders, digital marketers, and agency owners who are spending on Google/Meta ads but ignoring Reddit — the contrast between what they spend and what Reddit costs (zero) drives conversions.
  • The India angle reel is specific: "Indian founders building for US audiences — Reddit is the channel that reaches US buyers before they even search Google. Here is how to show up there without sounding like an ad." This is genuinely underused and high-converting content.
  • Use the tool on your own brand while building it — share your citation tracking dashboard publicly as build-in-public content. Your own usage proves the product works.
  • Cold DM Indian SaaS founders and marketing agencies who are actively running LinkedIn and Google ads — show them their own brand's current AI citation score (likely zero) and the tool that fixes it.

Who pays, and why

  • Indian B2B SaaS founders targeting US audiences who want organic US traffic without paying for ads — Reddit is the channel, AI citation is the outcome they care about.
  • Indian digital marketing agencies managing content and community for B2B clients who need to add Reddit + AEO as a service offering.
  • Product marketers at Indian SaaS companies who want to track competitor brand mentions on Reddit and measure AI share-of-voice against competitors.

BUILD_PROMPT.txt
I want to build a Reddit marketing and AI citation tracking platform for the Indian B2B market, inspired by ReddGrow AI (reddgrow.ai — $17,091 last 30 days on TrustMRR, ₹14.4L/month Stripe verified), scoped to ship a wor
king version in a single weekend. Core product: 1. User enters their brand name, keywords, competitor names, and the problem their product solves. 2. Reddit thread discovery: the system searches Reddit for threads matching these keywords — conversations where users are asking for recommendations, comparing tools, or describing problems the brand solves. Sorted by upvotes and recency. 3. AI response drafter: user clicks "Draft response" on any discovered thread. Gemini API reads the full thread context and writes an authentic, helpful community response that naturally mentions the brand only where relevant — Reddit tone, not marketing tone. 4. Brand mention monitor: hourly job checks Reddit for new mentions of the brand and competitors. Sentiment analysis (positive/negative/neutral). Email or WhatsApp alerts for new mentions. 5. AI citation tracker — the core differentiator: every morning, the system asks ChatGPT, Perplexity, and Claude "what is the best tool for [user category]?" and records whether the brand appears. Tracks the score over time, showing whether Reddit activity is increasing AI recommendations. 6. Analytics dashboard: Reddit presence score, mention trend, AI citation score over time, competitor comparison. 7. Pricing: Rs2,999/month Starter (5 keywords, 3 AI engines tracked, 50 thread alerts/month), Rs6,999/month Pro (unlimited keywords, daily citation checks, competitor tracking, response drafter). Stack: Next.js 14, Supabase, Reddit API or Pushshift for thread discovery, Gemini API for response drafting, OpenAI and Perplexity APIs for citation tracking, Vercel Cron for scheduled monitoring, Razorpay for UPI-first billing. Deploy: Vercel. Help me step by step: 1. Set up Reddit API OAuth and build the thread discovery search with keyword filtering. 2. Build the thread dashboard with upvotes, subreddit, and preview display. 3. Build the Gemini response drafter that reads thread context and writes authentic community responses. 4. Build the hourly mention monitor with sentiment analysis. 5. Build the AI citation tracking job — how to query ChatGPT, Perplexity, and Claude for brand mentions. 6. Build the citation score dashboard with time-series tracking. 7. Set up Vercel Cron for automated monitoring and daily citation checks. 8. Wire up Razorpay for subscription tiers. India-first: the tool should specifically include r/IndiaBusiness, r/indianstartups, and r/india in the monitoring scope for Indian brands targeting domestic audiences. The AI citation tracker should also include Google AI Overviews as a fourth engine. If I get stuck, tell me to ask @buildwithkanhaa.
