Is trending content discovery available through a REST API for external tools?

Yes on Business and Teams. The REST API accepts a topic, platform filter, and time window (7, 14, or 30 days) and returns high-engagement posts with metrics, hashtags, and URLs. Useful for piping discovery into Notion, Airtable, or a custom brand profile dashboard. Premium covers the UI search only.

Can I save searches and get notified of new viral posts in my niche?

Yes. Save any topic search as a watchlist with a custom name. New posts matching the topic, platform, and engagement threshold show up in the daily digest email and on the inspiration board. Set watchlists per brand profile so an agency with multiple clients sees only relevant trends without manual searching.

Does discovery work across multiple brand profiles for agencies and creators?

Yes. Each brand profile keeps its own inspiration board, saved searches, and watchlist topics. The cross-brand discovery view on Business and Teams aggregates results so an agency can spot a niche trend appearing across two or three clients. Switch brand profile in the top bar and search history follows.

Can I bulk-import trending posts into my PostNext draft queue?

Yes. Select up to 25 trending posts on the inspiration board and choose Remix into drafts. PostNext generates platform-tuned drafts using the AI Content Creator, with your brand profile tone and hashtag rules layered on top. Each draft is editable before scheduling and respects per-network length and aspect ratio rules.

How does discovery handle privacy and attribution of competitors' viral posts?

Only public posts are indexed. Private accounts, protected tweets, and unlisted videos never appear. PostNext never republishes a competitor's media verbatim. The Remix flow uses the trending post as a structural reference (hook style, hashtag pattern) and the AI generates fresh wording under your brand profile.

Can I filter discovery by engagement threshold or hashtag count range?

Yes. Set minimum likes, shares, comments, or views per post, plus a hashtag count range. Useful when filtering noise from outright viral content. Combine with platform and time window to narrow a niche search. Watchlists save the thresholds so the daily digest only surfaces posts that crossed your bar in 24 hours.

Does discovery cover languages other than English for non-English markets?

Yes. The discovery index covers 50+ languages including German, Spanish, French, Portuguese, Russian, Japanese, and Korean. Set the brand profile's target language and search results return posts in that language. The Remix flow generates AI drafts in the same language by default. Cross-language searches help spot trends across markets.

Can I migrate inspiration boards from Pocket or Notion into discovery?

Yes. Export bookmarks or post URLs as CSV from Pocket, Notion, or Raindrop, then import to a new inspiration board. PostNext fetches each post's metrics, hashtags, and media where the source platform allows. Existing tags carry over as labels. Run the Remix flow to convert imported references into AI-drafted posts.

How Marketers Use Trend Discovery

Maya Rodriguez

"Researching trending posts used to mean an hour of scrolling. PostNext gives me a sortable list of the highest engagement posts in my niche from the last 14 days, with the hashtags attached. I now plan a week of content in about twenty minutes."

James Sullivan

"The hashtag shortlist for each search saved us a lot of guessing. We were running the same five tags on every campaign; trend discovery surfaced ten more that were active in our space and the click-through on our LinkedIn posts went up noticeably."

Sophia Bennett

"What I like is that it does not pretend to predict virality. It just shows me which recent posts pulled engagement and lets me adapt the format. We tested short carousels after seeing them trend on Instagram and they ran ahead of our usual single image posts."

Questions about how trend research and hashtag discovery work in PostNext.

What does the trending content discovery tool do?

It searches recent high-engagement posts across X, Instagram, LinkedIn, TikTok, YouTube and Threads for any topic you enter. This is a research tool for content ideation, not a virality predictor.

Six platforms: X (formerly Twitter), Instagram, LinkedIn, TikTok, YouTube and Threads. Search all six together or filter to a single network. Engagement counts are pulled per platform.

Per-platform engagement counts (likes, comments, shares, views where the network exposes them), posting date, the hashtags used, the author handle and a relevance score against your search.

How do I turn the research into actual posts?

Save trending posts to an inspiration board, generate a shortlist of ideas drawn from the formats currently working, and send them into the PostNext composer or scheduler.

No. There is no reliable virality predictor. The tool shows which recent posts in your niche earned strong engagement so you can write content informed by what is already working.
