Tagline: Replic helps startups gain traction by promoting and actively engaging on social, so they grow like they already have a full marketing team.

Inspiration

As founders, we know the struggle: you need to post consistently to build traction, but you're too busy coding to craft every tweet. You can't afford a marketing team, but you need to look like you have one.

The Problem:

Hours wasted crafting social posts
Missing engagement opportunities while building
Inconsistent brand voice across posts
Great product updates, no time to promote them

The Solution: AI-powered social automation with human approval built-in.

How we built it

Frontend:

Next.js 14 + TypeScript
Shadcn UI components
Supabase for real-time data

Core Services (Python/FastAPI):

Ingress Workers: Poll X/Reddit (native APIs) and queue items.
Rate-Limiter & Scheduler: Token buckets per platform + exponential backoff.
Safety & Relevance: Keyword/handle match + topic filters (politics/NSFW) + duplicate suppression.
LLM Orchestrator: Persona prompts, <300 chars, style-matching.
Approval Gateway: iMessage/WhatsApp webhooks → approve/edit/reject → post.
Messaging: Photon iMessage Kit; WhatsApp Business API.
AI: xAI Grok
Data: Supabase Postgres (Brands, Keywords, Activities, Approvals), Redis (queues, rate tokens).

Architecture

Ingress (Social Media - X/Reddit) → Queue → Filter/Guardrails → LLM Reply/Posts → Policy (auto vs. approval) → Channels (post) → Activity Log/Dashboard.

What’s novel

Presence, not just summaries: It participates in threads with tasteful, short replies.
Chat-native approvals: Founders approve from iMessage/WhatsApp, no dashboard hunting.
Low-noise by design: Hard limits, spacing, topic skips, and idempotency keep it human.
