ExoHabit Daily

An AI briefing app that turns new exoplanet discoveries (atmospheric escape, biosignatures, habitable-zone finds) into short, plain-language explainers for curious space fans and science-curious adults.

Target user

space enthusiasts and curious adults who follow astronomy news but can't read papers

Features
  • Daily 3-minute briefing on the latest peer-reviewed exoplanet news with a 'why it matters' hook
  • Interactive 'habitability score' for each new planet using radius, temperature, and atmosphere data
  • 'What does helium escaping actually mean?' explainers that translate jargon into everyday analogies
  • Saveable personal archive so users can build a timeline of how exoplanet science evolved
Why now

JWST and ground-based telescopes are producing a steady drumbeat of habitable-zone discoveries; helium-escape findings are the kind of news that breaks briefly then disappears, leaving curious fans with no way to dig deeper

Demand
4/10

Existing free sources (Universe Today, NASA Exoplanet Watch, Planetary Society, DailySpace app, Exoplanet magazine) already serve this audience, and the cited HN post was a modest 51 points — real but niche interest.Universe Today - Space and Astronomy NewsExoplanet Watch Newsletters - NASA Science

Whitespace

Crowded free landscape: Universe Today, NASA Science, Planetary Society, Exoplanet Magazine, NCCR PlanetS newsletter, and the Exoplanet catalog app already cover this beat — minimal differentiated whitespace for an AI explainer.ExoplanetExoplanet News — NCCR PlanetSExoplanet Exploration News - NASA Science

Monetization
3/10

NASA, Universe Today, and Planetary Society offer top-tier exoplanet coverage for free, and NCCR's exoplanet newsletter is also free — very hard to charge when free official sources dominate a niche audience.Universe Today - Space and Astronomy NewsExoplanet Watch Newsletters - NASA Science

Longevity
9/10

JWST continues producing exoplanet headlines (TRAPPIST-1e atmosphere in Sept 2025), and Roman, ARIEL, and ground-based ELT guarantee a multi-decade discovery pipeline.Webb spots first hints of atmosphere on a potentially potentially habitable worldJWST Exoplanet Breakthrough Discoveries 2025 | Zendar Universe

Feasibility
7/10

Straightforward LLM + arxiv/NASA API pipeline to summarize abstracts, but scientific accuracy and tone require curation; mobile-app distribution and summarization are well-trodden territory.Exoplanet
