Radar vs Kompozy: an honest comparison of Particle's podcast search engine and Kompozy's content generation engine — and which one your workflow needs.
If you found Radar and started wondering whether it's the tool that turns podcasts into content, this page is the honest answer: it isn't, and Kompozy is a different kind of product. I run Kompozy, and I'm not going to pretend Radar is a competitor we out-feature. It solves a real problem we don't touch, and we solve a problem it was never built for.
Radar, from Particle, is a podcast search engine and intelligence platform. It transcribes and indexes 130,000+ shows and makes what was said searchable — by people and, crucially, by AI agents through an API and MCP endpoint. It finds quotes, tracks entity mentions, and fires alerts. That's discovery and monitoring. Kompozy is a content generation and multi-platform publishing engine: it turns a source into finished posts across video, image, text, blog, and newsletter and publishes them.
The useful question isn't "which is better" — it's "where in your workflow are you stuck." If you can't find what to make content about, or you need to monitor podcasts for mentions, Radar is the tool and no amount of Kompozy replaces it. If you know what to say and your bottleneck is producing and shipping it across platforms, that's Kompozy, and Radar does none of it. Many creators would use both: Radar to catch the moment, Kompozy to make and publish the response.
Everything below is grounded in real 2026 information — Radar details from Particle's August 26, 2026 launch coverage, Kompozy pricing from ours. No fabricated weaknesses, no straw men.
Radar is a podcast search and intelligence platform. It transcribes podcast audio at scale — Particle says more than 130,000 shows, adding roughly 20,000 episodes a day across the Apple Top 200 and 135 verticals — and layers on speaker labels and entity metadata (people, companies, brands, topics). On top of that it extracts key quotes, highlights, and self-contained clips with timestamps, tracks when an entity is mentioned, and sends customizable alerts by email, Slack, or webhook. It also runs a dedicated podcast-ads search engine with sponsorship and brand-suitability data. All of it is queryable through an API and an MCP endpoint, which is why its highest-volume customers are hedge funds and AI search platforms, not creators. What Radar does not do is make anything. It writes no captions or scripts, generates no images or video, builds no carousels, and publishes to no platform. It reads and structures other people's audio; the output is data, not content.
People land on a "Radar alternative" search for two different reasons. Some want a cheaper or creator-focused podcast search tool — for them the real alternatives are other podcast-search and monitoring services, and this page is honest that Kompozy is not one of those. Others found Radar while looking for a way to turn podcasts into content, realized it only finds and structures audio, and need the piece that actually produces posts. That second group is who Kompozy is for. The gap is scope, not quality. Radar is excellent at discovery and monitoring and genuinely serves finance, search, and research customers. But a creator's bottleneck is usually production and distribution: taking a quote, a trend, or their own episode and turning it into a captioned Short, a carousel, a blog, and a newsletter, in a consistent brand voice, scheduled everywhere. Radar stops at the find. Kompozy is the generation-and-publishing layer that starts there.
| Feature | Radar (Particle) | Kompozy | Note |
|---|---|---|---|
| Podcast search across 130,000+ shows | Yes | No | Radar's core. Kompozy is not a podcast index and does not search other people's audio. |
| Entity/mention alerts (email, Slack, webhook) | Yes | No | Radar is a monitoring tool; Kompozy has no listening/alerting layer. |
| Timestamped quote & clip extraction from other shows | Yes | No | Radar surfaces quotes and clips for research from any indexed show. |
| API + MCP for AI agents | Yes | Partial | Radar is built for agent access. Kompozy offers webhooks and Zapier; a full public API is on the roadmap. |
| AI text generation (captions, scripts, blogs) | No | Yes | Radar structures existing audio; Kompozy writes new copy in your voice. |
| AI image generation (carousels, quote cards) | No | Yes | Quote graphics, carousels, and photo posts — generated, not indexed. |
| AI / avatar video generation | No | Yes | Kompozy produces Persona Shorts and avatar video; Radar makes no video. |
| Clip your own long-form video into shorts | No | Yes | Kompozy cuts publishable Clipped Shorts with captions; Radar only clips audio for search. |
| Persona Brief / brand-voice governance | No | Yes | Kompozy enforces tone and banned phrases across outputs; Radar has no authoring layer. |
| Multi-platform scheduling & publishing | No | Yes | Kompozy publishes across the eight social platforms plus blog and email; Radar publishes nothing. |
| Per-post review / approval pipeline | No | Yes | Kompozy gates each post before it ships; not applicable to a search tool. |
| Sponsorship / podcast-ads research data | Yes | No | Radar's ads search engine and sponsorship data have no Kompozy equivalent. |
| Repurpose your own podcast episode into posts | Partial | Yes | Radar indexes your episode for search; Kompozy turns it into finished, published content. |
| Tier | Radar (Particle) plan | Radar (Particle) price | Kompozy plan | Kompozy price |
|---|---|---|---|---|
| Entry | Radar Consumer | $29/mo per seat | Kompozy Starter | $99/mo (5,500 credits) |
| Team | Radar Business | $399/mo (20 seats) | Kompozy Pro | $299/mo (18,000 credits) |
| Enterprise / API | Radar API | Custom (usage-based) | Kompozy Enterprise | Custom (sales-led) |
Here's the honest pitch, and it's not the usual "we do more." Radar and Kompozy barely overlap. Radar is a listening-and-search instrument for podcasts — the best answer if your problem is finding what was said or watching for it. Kompozy is a content factory with a publisher attached — the answer if your problem is turning an idea, a quote, or your own episode into a week of finished posts across platforms.
The reason this page exists is that "turn podcasts into content" is a search people run hoping a tool does the whole thing, and no single product does both ends well. The clean setup is to use each for its half: let Radar catch the trend, the mention, or the quotable line, then paste it into Kompozy and let it generate a Persona Short, a carousel, quote graphics, text posts, a blog, and a newsletter in your brand voice — scheduled and published everywhere on Autopilot.
If your real job is production and distribution, start on Kompozy Starter at $99/mo (5,500 credits) and add Radar only if you also need the discovery layer. If your real job is research and monitoring, buy Radar and don't expect it to make your content. Match the tool to the bottleneck you actually have.
Not really — they solve different problems. Radar is a podcast search and intelligence platform that finds and structures spoken audio for people and AI agents. Kompozy is a content generation and multi-platform publishing engine. If you need to search or monitor podcasts, use Radar; if you need to produce and publish content, use Kompozy. Many creators use both.
No. Radar transcribes, indexes, and searches podcast audio and extracts quotes and clips for research, but it generates no captions, images, or video and publishes nothing. To turn a podcast — or a quote Radar surfaced — into finished posts across platforms, you need a content engine like Kompozy.
At launch Radar listed a Consumer plan at $29/mo per seat and a Business plan at $399/mo for 20 seats, with custom API pricing. Kompozy starts at $99/mo (Starter, 5,500 credits) and $299/mo (Pro, 18,000 credits). They aren't competing line items — one prices research seats, the other prices content generation.
Kompozy generates content and publishes it: AI captions and scripts, images and carousels, avatar and clipped video, blogs, and newsletters, all in a governed brand voice, scheduled across the eight social platforms plus blog and email. Radar does none of this — it's a search and monitoring tool for spoken audio.
Radar searches and monitors 130,000+ podcasts, extracts timestamped quotes and clips, tracks entity mentions with alerts, and exposes all of it to AI agents via an API and MCP endpoint. Kompozy has no podcast index or listening layer, so for discovery and monitoring Radar is the tool.
