KWatch.io

You define terms once and KWatch.io watches Reddit, Hacker News, X, LinkedIn, Facebook and YouTube for them. Each platform has its own alert quota, which is the main reason plan choice matters. Reddit and Hacker News get the largest allowances, so research-heavy teams usually pay less than social-first teams.

Matches land in your inbox, a Slack channel, or an HTTP endpoint, usually within seconds and up to a minute when traffic spikes. The webhook route is what makes this useful for automation: pipe the payload into a CRM, a spreadsheet, or an AI agent and skip manual copying. Email alone is fine for a solo user who checks messages a few times a day.

Instead of watching a keyword, you watch a thread. Point KWatch.io at a post or a comment and every new reply triggers a notification. This is the feature that fits launch threads, AMAs, and support questions where the exact wording is impossible to predict. Quotas are separate from keyword alerts, so tracking doesn't eat your keyword allowance.

Once a keyword fires, the AI reads the surrounding context and scores the mood of the mention. That turns a raw alert feed into something you can skim: ten mentions with eight positive scores need less attention than two negative ones. It won't catch sarcasm reliably, and the score is a summary, not a verdict.

The dashboard keeps matched results so you can revisit them after the alert is gone. Filters help when a broad term like "automation" returns noise from unrelated industries. On Business and Enterprise plans you can upload a CSV of keywords instead of typing them one by one, which matters once a list passes a few dozen entries.

Invite colleagues to a team and route the same alert to several people. This is gated to the Business plan and above, so a two-person startup on Essential will need to forward emails by hand. For agencies running several clients, the Enterprise plan adds multi-client management, which keeps separate keyword sets apart.

Business and Enterprise plans expose an API and an MCP server alongside webhooks. The MCP route lets an AI assistant query or manage trackers with the same key, which suits teams already running agents for research. Smaller plans have no programmatic access at all, a gap worth checking before you commit.
