As answered by people managing Project Euler and Intoru.ai.
Intoru.ai's answer:
We're a small bootstrapped team that kept spotting people describe the exact problem we solved on Reddit, always too late and buried under keyword noise. So we built the tool we wanted: AI that finds real buyers on Reddit in real time and helps you win the conversation.
Intoru.ai's answer:
Bootstrapped and early-stage SaaS founders and small B2B teams who want customers from Reddit without hiring a marketer or breaking subreddit rules.
Intoru.ai's answer:
Next.js and Tailwind on the front end, Node.js and Fastify on the back end, MongoDB, Redis with BullMQ for job queues, and Qdrant for vector search. The intent-judging pipeline runs on OpenAI and additional LLM providers.
Intoru.ai's answer:
Intoru judges Reddit posts in real-time for real buying intent with AI, instead of matching keywords the way alert tools do. It surfaces people actually asking for a product like yours, drafts a reply that fits each subreddit's rules, and stays with the conversation from first comment to closed deal.
Intoru.ai's answer:
Other tools make you pick subreddits or keywords up front. Even the ones that generate that list for you can only ever find leads inside it. Intoru watches all of Reddit in real time and judges each post for buying intent, so you catch people no keyword list would have caught. Then it doesn't stop at finding them: it drafts the reply, respects each subreddit's rules, and carries the whole conversation to a close.
