Upthread vs ReplyHey
ReplyHey scores intent on Reddit, X and LinkedIn twice a day, drafts a reply or a DM, and its extension can post approved drafts from your browser on autopilot. Upthread works on Reddit only: it drafts public replies, you click Comment, and it tracks each one.

Why people look beyond ReplyHey.
ReplyHey is built for lean B2B growth teams. Paste your website and it learns what you sell, then twice a day finds the strongest conversations on Reddit, X and LinkedIn, scores each from 0 to 100, and prepares a public reply or a DM for your review. 1
It also sends them. Its Chrome extension, or your own AI agent over MCP with Playwright, posts approved drafts through the accounts signed in to your browser, 45 seconds apart, and an autopilot mode keeps working the queue as new leads arrive. 2
Upthread does the finding and drafting for Reddit only, and stops there on purpose. It ranks the threads Google and AI answers show your buyers, drafts public replies with your disclosure, never sends DMs, and leaves the final click to you before it tracks what the reply did.
Who should choose which.

ReplyHey in brief

- An autopilot mode works the queue on its own, 45 seconds apart with random jitter, and picks up new leads as they arrive. 2

Switching from ReplyHey.
Upthread starts from your website address: it drafts a brand profile, then you edit the competitors, keywords, buyer questions and focus subreddits it suggests, write your role and disclosure line, and choose engines and a country. The first discovery and visibility runs follow at once, and the extension, which only fills in the comment box, is optional.
What you bring across
- Your website, which Upthread reads to draft a brand profile and suggest keywords, competitors and buyer questions.
- The subreddits you watch, as focus subreddits that raise a thread's priority in your inbox.
- Your Reddit account, the only one Upthread works with; the extension can fill in its comment box.
- The phrases buyers use in your leads, as keywords and buyer questions for discovery and AI answer checks.
What works differently
- ReplyHey's autopilot posts approved drafts on its own, one every 45 seconds or so. Upthread never posts: its extension fills in the comment box and you click Comment, one reply at a time. 2
- ReplyHey answers a subreddit that bans promotion with a DM draft. Upthread sends no DMs: it drafts public replies and posts only, grounded in the subreddit's rules, with your disclosure when a draft names your brand. 1
- ReplyHey says it does not track whether AI assistants mention you. Upthread checks Google AI Overviews and AI Mode twice a week and four AI assistants weekly, with mention rate, share of voice and the Reddit threads each cites. 3
- After you post, Upthread records each reply's score over time, whether moderators removed it, and the thread's citation history.
How Reddit access is changing
Reddit is closing its public API and moving toward logged-in viewing. This matters for any tool that reads Reddit, so each comparison states only what the tool itself says about its data source.
- On Oct 29, 2026, Reddit said it will shift to a primarily logged-in experience, starting with tests in select markets outside the US. 4
- 9to5Mac reported that Reddit will start requiring a logged-in account for most of its content. 5
- Reddit's CEO said most unauthorized access to its content happens through the logged-out experience. 6
ReplyHey and Upthread: questions.
Does ReplyHey post for me?
Yes, from your own accounts. Its Chrome extension, or your AI agent with Playwright, types approved drafts into Reddit, X or LinkedIn and posts them, and autopilot keeps working the queue while you are away. Upthread never posts; you click Comment. 2
Does ReplyHey send DMs?
Yes. Where a subreddit bans promotion, it gives you a DM draft and a compose link instead of a public reply, and its LinkedIn automation does comments but not DMs. Upthread drafts public replies and posts only, and sends no DMs. 1
Does ReplyHey track AI answers?
No. It says it works on the input side, the Reddit threads assistants read, and points to other tools for measuring the output. Upthread measures both: the threads each engine cites and your mention rate in its answers. 3
Which one costs less?
ReplyHey. Starter is $34.99 a month for Reddit leads, and Base $49.99 with X and LinkedIn. Upthread Starter is $49 a month and includes AI answer tracking and reply tracking, on Reddit only. 1
Can my team share one ReplyHey account?
Today ReplyHey is one account per subscription, with no separate seats or role-based approvals yet. Upthread Growth includes 3 seats and Agency 10, each person posting from their own Reddit account. 1
