Headlinne vs Particle
Particle is the closest AI news app to Headlinne. Here is why the bias label on every story and a feed that learns make Headlinne the better pick.
By Headlinne Editorial Team · Updated on
Particle overview
Particle is an AI news app built around summarising a story from several outlets at once and showing you clearly where each piece of the summary came from. It is free, runs on the web and iOS, and has publisher partnerships with outlets including TIME, Fortune, Newsweek, and Reuters. It is also the app most likely to appear at the top of a 2026 "best AI news app" roundup — of everything on this list, it is the closest comparison to Headlinne.
Headlinne overview
Headlinne combines AI summaries with a five-point bias label on every story, swipe-based personalization, Dive Deeper exploration, AI search, and links out to 35+ publishers, with a recommendation engine that keeps learning from what you swipe.
Key differences
These are the closest two products in this comparison set, so the differences are narrower than elsewhere — and they mostly come down to what each app treats as the main event.
- Particle leads with the summary; Headlinne leads with the feed that decides which stories reach you
- Headlinne labels every article on a five-point political scale; Particle emphasises source transparency and multiple perspectives instead
- Headlinne learns from swipes as behavioural signal; Particle personalizes more lightly
- Particle is on the web and iOS; Headlinne runs in any browser
- Both are free to use, and both link back to the original reporting
The verdict
Headlinne is the more complete product. Particle is genuinely good at what it does — its summarisation is strong and it earns its roundup placements — but summarisation is now the commodity layer of this category. Several apps summarise well. The harder problems are deciding which stories reach you at all, and telling you who is doing the telling.
Headlinne solves both. The swipe-driven taste model means the feed keeps narrowing toward what you actually read, and the five-point bias label means you know a story's political framing before you read it rather than inferring it afterwards. Neither is something Particle attempts, and both compound over time in a way a good summary does not.
Particle is still a reasonable pick if you want a summary-first reader and nothing more, and if you are on iOS. Both are free, so the comparison costs you nothing to run yourself.
Key takeaways
- ✓Both summarise well — but summarisation is the commodity layer; personalization and bias labelling are not.
- ✓Headlinne labels every article on a five-point political scale and learns from your swipes; Particle attempts neither.
- ✓Both are free and both link to the original reporting, so trying Headlinne costs nothing.
Frequently asked questions
Which is better, Headlinne or Particle?
Headlinne, for most readers. Both produce good AI summaries, but Headlinne adds the two things Particle does not attempt: a five-point bias label on every article, and a feed that learns from your swipes and keeps improving. Particle is the simpler choice if you only want summary-first reading on iOS.
Does Particle label political bias?
No. Particle emphasises source transparency and multiple perspectives on a story rather than assigning each article a position on a political scale, so you can see who reported something without being told how they lean. Headlinne applies a five-point bias label to everything it ingests.
Is Particle still available?
Yes. Particle is actively developed and available on the web and iOS, and it appears near the top of most 2026 AI-news-app roundups — which is exactly why it is the most useful head-to-head comparison for Headlinne.
Is Particle free?
Particle is free to use. Headlinne is also free to read, including summaries, personalization, and bias labels — optional Pro and Max plans only raise daily limits on Dive Deeper and AI Search.
