Find the Reddit threads where people ask for what you sell

DemandLark watches the communities your buyers use, flags the posts where someone needs a product like yours, and helps you write a genuinely useful reply. You post it yourself.

Illustrative example of the DemandLark Opportunities list: a thread marked Hot with the reason it matched, whether the subreddit allows promotion, and the competitors mentioned, next to an Overview of threads found per day, the reply pipeline and top communities. All values are made up.

How it works

From your website to a reply worth posting

Four steps. The AI does the reading and sorting; you decide what to say and where to say it.

  1. Step 1

    Enter your website

    AI reads your site and works out what you sell, who buys it, and what those people type on Reddit: buying-intent phrases, complaints about competitors, and the problems you solve. It also picks the subreddits worth watching.

    You can edit every keyword and subreddit it suggests.

  2. Step 2

    We read those communities twice a day

    Every morning and evening, plus whenever you press Refresh, we read new posts in your subreddits. Each one is filtered and then judged by AI against your product, so you see real requests, not keyword noise.

    Locked, archived and NSFW threads are skipped.

  3. Step 3

    Review ranked opportunities

    Threads land in Opportunities ranked 🔥 Hot, Good match or Maybe, with a short reason why each one matched, any competitors mentioned, and whether the subreddit allows links.

    Read the whole thread without leaving DemandLark.

  4. Step 4

    Reply yourself, then track it

    Get a drafted reply that answers the question first, in your voice, with an honest disclosure. Edit it, post it yourself on Reddit, mark it posted, and we track its upvotes and whether it was removed.

    DemandLark never posts on your behalf.

What you get

Everything between “someone asked” and “I answered”

Each part is in the product today. Nothing here posts on your behalf.

Reply drafts in your voice

A helpful-first draft that answers the question before it mentions you, with a disclosure line. You edit it, you post it, you stay in control.

Illustrative reply draft that answers the question first, mentions the product once, leaves out links because the subreddit doesn’t allow them, and ends with a disclosure.

  • AI setup from your website

    Product, buyers, keywords in three groups (buying intent, competitor pain, problems) and a list of subreddits, worked out from your homepage. Edit anything.

  • Ranked opportunities

    Every post is judged against your product and sorted into 🔥 Hot, Good match or Maybe, with the reason it matched written in one plain sentence.

  • The full thread, in one place

    Read the post and its comments inside DemandLark, see which competitors come up, and check whether the subreddit allows links before you write anything.

  • Slack and Discord alerts

    Get a message when a 🔥 Hot thread appears, so you can answer while the conversation is still fresh.

  • Tune it in plain English

    Tell the AI "stop showing me job posts" or "more threads about pricing" and it updates your keywords and filters.

What we won’t do

Reddit works when you’re useful. We built around that.

Communities can spot a campaign in seconds. So the product leaves the posting, and the judgement, to you.

  • We never post for you

    There's no autoposting, no scheduling and no account pool. You read the draft, change what you want, and post it from your own Reddit account.

  • We respect subreddit rules

    Each opportunity shows whether the community allows links. When a subreddit doesn't, the draft leaves the link out.

  • Helpful first, always disclosed

    Drafts answer the person's question before mentioning your product, and include a plain disclosure that you work on it. No posing as a happy customer.

  • No vote games

    We don't buy, trade or automate votes, and we don't run sockpuppet accounts. Nothing in the product can do it.
