What they have in common
All three are Reddit tools that look for intent, not every mention: someone asking for a recommendation, comparing options, or describing the problem you solve. All three score each post, and none of them posts, comments or sends messages for you. On Reddit, a reply you write yourself that answers the question first and says you made the tool works far better than a pitch.
Where they differ
- Speed. IntentAlert reads new posts in real time and alerts you within seconds. CollectIntent scans 1 to 2 times a day per project. First10 sends a daily email on Solo and Pro and a weekly one on Free.
- Where you read results. IntentAlert pushes alerts to Telegram, Slack or a webhook. CollectIntent is an inbox you triage, and its MCP server lets Claude, ChatGPT or Cursor read it. First10 is only an email, with nothing to log in to each day.
- Reply drafts. CollectIntent and First10 both draft a reply you post yourself. IntentAlert gives a score, a % match and a summary of what the poster needs; its site does not mention reply drafts.
- Setup. IntentAlert asks you to describe your product and pick subreddits, then set match and intent thresholds. CollectIntent suggests subreddits and keywords from your URL. First10 takes one line or your site and picks the subreddits for you.
- Price. IntentAlert and CollectIntent both start at $29 a month and reach $79 for 3 products; CollectIntent adds Growth at $199. First10 has a free weekly plan with no time limit, Solo at $19/month or $190/year, and Pro at $49/month for 3 products, with a 7-day refund.

Questions founders ask
What is the difference between IntentAlert, CollectIntent and First10?
All three look for public Reddit posts from people who need what you sell. IntentAlert (intentalert.io) watches the subreddits you pick in real time, gives each post a 0-10 intent score, a % match and a short AI summary, and pings you in Telegram or Slack. CollectIntent (collectintent.com) suggests subreddits and keywords from your URL, scans them once or twice a day, scores posts 0-100 and puts them in a triage inbox with AI reply drafts you copy and post yourself. First10 (first10.dev) emails you one ranked list of Reddit posts with a short reply draft for each, with a free weekly plan that never expires.
Which one is free to try?
As of November 13, 2026: First10's free plan has no card and no time limit (1 product, weekly email, top 5 Reddit posts with drafts). CollectIntent lets you create a project and run the first scan free after signup, with one match unlocked; the full inbox and reply drafts need a plan. IntentAlert's pricing section lists paid plans only, with no free plan or trial shown.
How much do they cost?
IntentAlert: Founder $29/month (1 product monitor, Telegram and Slack alerts), Company $79/month (3 product monitors, webhooks, 3 team seats); 6-month billing saves 17% and annual saves 33%. CollectIntent: Starter $29/month (1 project, 8 subreddits, 1 scan a day), Pro $79/month (3 projects, 20 subreddits, 2 scans a day), Growth $199/month (10 projects, 50 subreddits). First10: Solo $19/month or $190/year (daily email, top 10 posts, 1 product), Pro $49/month (3 products), 7-day refund, cancel anytime. Prices are what each site showed on November 13, 2026.
Which one is fastest?
IntentAlert is built for speed: it says new posts are usually scored within seconds and pushed to Telegram or Slack. CollectIntent runs 1 scan a day per project on Starter and 2 on Pro and Growth. First10 sends one email a day on Solo and Pro and one a week on Free. If you can reply within minutes, real-time alerts help; if you check Reddit once a day, a daily ranked list is easier to act on.
Do any of them post for me?
No. IntentAlert says it never posts, comments or messages on your behalf. CollectIntent says it does not comment, vote or send messages on Reddit, and you post its drafts yourself. First10 writes a short reply draft for every post and never posts or DMs for you. IntentAlert's site does not mention reply drafts, so you write those replies from scratch.
Is First10 the same as first10.co?
No. First10 (first10.dev) is a separate product and is not connected to first10.co, getfirst10.com or first10.ai.
