Promote your product naturally
Sift monitors Reddit and Hacker News for conversations where your product is relevant, then drafts a reply for you. Review it in your dashboard or get it via SMS. Approve, edit, or skip.
Monitoring where your audience already is
Features
AI finds the conversations. You decide which ones are worth joining.
Smart opportunity detection
Sift uses semantic search and AI scoring to find posts where your product genuinely helps — not just keyword matches. Every post is scored on relevance, intent, and engagement potential.
Instant value on signup
Don't wait days for new posts to trickle in. Sift backfills historical posts from your target communities, scores them, and surfaces opportunities you can act on right away.
AI-drafted replies
Every opportunity comes with two AI-drafted replies: one that's genuinely helpful with no product mention, and one that leads with value then naturally introduces your product. Review and approve via SMS or your dashboard.
Continuous monitoring
After backfill, Sift watches your target communities in real-time. New posts are scored as they appear, and only the best opportunities per day reach you — no notification fatigue.
Two reply modes
Not every post needs a pitch. Sift knows the difference.
Build credibility first
When a post is relevant but not a natural promotion fit, Sift drafts a genuinely helpful reply — advice, experience, or discussion. No product mention at all. A healthy mix of engagement and promotional replies keeps your account looking balanced and genuine.
Example draft
“We ran into the same issue scaling our webhook pipeline. What worked for us was switching to a fan-out pattern with per-tenant queues — keeps backpressure from one client from affecting others. Happy to share more details if helpful.”
Mention when it fits
When the post is a strong fit — the author has a problem your product solves — Sift drafts a reply that leads with value, then mentions your product with honest disclosure.
Example draft
“This is a common pain point with invoice reconciliation. One approach: batch your matching jobs and run them async. Full disclosure — I built Ledgr which does exactly this, but the pattern works regardless of tooling.”
Account health
Stay a real participant. Not a spammer.
Ratio tracking
Monitors your balance of promotional vs genuine comments across platforms.
Smart nudges
Alerts when your recent posts lean too promotional. Suggests threads to engage in genuinely.
Human profile
Occasionally suggests off-topic threads to build a natural, human-feeling posting history.
How it works
From setup to your first reply in minutes.
Describe your product
Tell us what you built in plain English. Sift suggests relevant subreddits and Hacker News topics, then tailors its reply style to match each platform's tone.
Review opportunities
Sift scores every post on relevance, intent, and engagement. Only the top opportunities per day reach you — each with AI-drafted replies you can approve, edit, or skip.
Stay healthy
Account health tracking ensures you're a real participant — not a spammer. Honest disclosure is built into every promotional draft.
Ethical marketing, not growth hacking
Other tools post stealthy product mentions across dozens of threads. That gets you banned. Sift takes the opposite approach — help first, mention your product only when it genuinely solves someone's problem, and with honest disclosure. The result is real credibility, not a shadowbanned account.
Transparent
Always discloses — "I built this" or "I work on the team"
Platform-aware
Adapts tone for each platform. Founder-direct on HN, conversational on Reddit.
Human-in-the-loop
Nothing posts without your approval. You always have the final say.
