AI-powered Reddit engagement built for small teams.
Building an AI-powered Reddit engagement and community-marketing platform for freelancers, founders, and small teams.
Subtle Reply AI helps businesses grow on Reddit without spending their days monitoring Reddit. Project-specific AI bots identify relevant conversations and draft useful, context-aware replies that add value first and introduce the product second.
Reddit has high intent. It also rejects bad marketing.
For freelancers, indie founders, and small startups, Reddit is full of people actively asking the exact questions their products answer.
But Reddit communities quickly reject anything that feels like generic promotion. Every subreddit has its own language, expectations, and tolerance for self-promotion.
Doing Reddit marketing well takes time every day.
Small teams either do the work manually or outsource it. The first option is expensive in founder time. The second often produces generic comments that damage trust.
Monitor dozens of subreddits for relevant threads.
Read enough context to contribute credibly.
Write a genuinely helpful, community-appropriate reply.
Mention the product without derailing the conversation.
Repeat the process consistently enough to build presence.
Keep the authenticity and community-fit of a thoughtful human reply while removing the hours of monitoring, matching, and drafting behind it.
Treat it as a full product. Not a wrapper around a language model.
Prodgrade built the marketing site, authenticated app, onboarding flow, AI reply pipeline, Reddit integration, billing, affiliate infrastructure, and the cloud environments underneath the product.
A few clear decisions.

One place to run Reddit as a growth channel.
Subtle Reply AI combines targeting, AI generation, automation, Reddit account access, billing, growth tooling, and multi-project management in a single SaaS product.
Teach the AI what your business actually does.
Every project starts with three plain-language questions. There is no prompt engineering and no technical configuration required.
That context becomes the foundation for every generated draft. Each project can maintain its own bot, business context, voice, and targeting, making the system practical for agencies and multi-brand operators too.
Only engage where it is actually relevant.
Users choose the communities where their audience spends time and the keywords that signal a useful opportunity to contribute.
The matching layer works inside those boundaries. That keeps engagement contextual by design instead of spraying generic comments across Reddit.
Targeting can scale from a small set of communities and keywords to broader, multi-project programs.
Helpful first. Promotional second.
For a matched Reddit thread, Subtle Reply AI reads the context and creates a response that directly contributes to the discussion before trying to introduce the user's product.
The goal is simple: every reply should still be worth posting even if the product mention were removed.
Problem, audience, value proposition, and positioning.
The actual question and surrounding conversation.
Tone, expectations, and self-promotion sensitivity.
How lightly or directly the product should be introduced.
Community-aware, useful, product-relevant.
You decide how hard the bot leans in.
A per-project confidence setting gives brands control over the visibility-versus-risk trade-off, from almost purely helpful replies to more explicit recommendations.
Hands-off when you want it. Reviewed when you don't.
Subtle Reply AI supports both approval-based workflows and automated posting. Teams can decide how much control to retain on a project-by-project basis.
Drafts are surfaced for review before they reach Reddit.
Approved projects can post through the connected Reddit account.
Posting happens through the user's connected Reddit account, so comments appear as the user rather than as an obvious third-party bot.
Built for people running more than one thing.
Users can run multiple projects from one account, each with its own AI context, target communities, keywords, Reddit connection, and subscription tier.
Projects, communities, keywords, mentions, and replies.
Quick visibility into changes across account activity.
Per-project plans and transaction history.
Move between businesses from one account.
Fitting into the stack small teams already use.
The product connects its AI, account, billing, affiliate, authentication, and communication layers through dedicated third-party integrations.
OAuth connection and comment posting on behalf of the user.
Context-aware generation built into the engagement pipeline.
Google sign-in and sign-up alongside email authentication.
Product plans, payments, and transaction history.
Tracking, commissions, partner attribution, and reporting.
Verification, password reset, and account communications.
The platform helps sell itself.
The build extended beyond the engagement engine. Prodgrade also created the acquisition and referral surfaces used to grow Subtle Reply AI itself.
Affiliate Program
Rewardful-powered partner flows with recurring commission, cookie attribution, marketing assets, and reporting.
Refer a Friend
In-app sharing lets existing customers directly invite new users through referral incentives.

Conversion-focused landing pages with pricing, FAQs, testimonials, and product storytelling.
A focused stack for a production AI SaaS product.
Subtle Reply AI combines a React product experience with a Python API, MongoDB, GPT generation, Reddit account access, billing, authentication, and managed cloud environments.
React · Vite · Tailwind · MUI
FastAPI · Python · MongoDB
OpenAI GPT · Prompt Scaffolding
Reddit · Stripe · Google · Rewardful
Authentication coordinated across the SPA and API.
Environment-based configuration for controlled releases.
Dedicated validation and error-handling workstream.
Cloud-hosted frontend and backend environments.
Third-party account access handled carefully.
The platform handles Reddit account access, billing information, and business context, so security was treated as part of the build rather than a later enhancement.
From landing page to posted Reddit comment.
Prodgrade delivered Subtle Reply AI as a complete, production-grade product: marketing experience, authenticated SaaS application, AI pipeline, Reddit integration, billing, affiliate infrastructure, and cloud deployment.
No-code project setup
To train a project's bot
Bots, targeting, Reddit accounts, and plans
User-controlled automation
Context-aware reply generation
Starter through Enterprise
Sophisticated underneath. Simple where the user touches it.
Context modeling, prompt scaffolding, matching, account posting, subscriptions, affiliate attribution, authentication, and infrastructure all live below the surface.
For the user, the experience stays straightforward: connect Reddit, describe the business, choose where to show up, and let the system do the reading and drafting.
A non-technical founder should be able to configure the product in minutes while still controlling targeting, tone, and automation.
A complete AI SaaS product, not just an AI feature.
Subtle Reply AI represents work across the full product lifecycle: UI/UX, React frontend, FastAPI and MongoDB backend, GPT and Reddit integrations, authentication, subscription billing, affiliate infrastructure, and cloud deployment.
The result makes one of the most difficult organic marketing channels significantly more approachable for founders and small teams.
