Histia: making world history fit in five minutes
I designed, built and grew Histia, a world history app that turns the past into short narrated stories, daily facts and quizzes. Here is how the product decisions were made.
The problem
Plenty of adults say they want to know more history. Very few open a 600-page book after work. What they do open, dozens of times a day, is their phone. The opportunity was not "another history app" but a format that competes with scrolling on its own terms: short, visual, finished in one sitting, and genuinely memorable.
Product decisions
- Stories, not lessons. Each story has a hook, a narrator and visuals that change with the narration, so it feels closer to a mini-documentary than a textbook page.
- Retrieval over reading. Stories end with quizzes, because recall is what makes facts stick. Daily facts and streaks give a reason to come back tomorrow.
- Local-first content. Stories ship with the app as structured data, so they load instantly and work offline.
- Social play next. A two-player duel mode is in progress, built to turn solo learning into something people share.
Where AI does the work
A content app lives or dies on volume and quality at the same time. One person cannot write, voice and illustrate dozens of stories by hand, so I built a pipeline:
- Scripts drafted with an LLM from a structured brief, then edited by hand for accuracy and tone.
- Narration generated with a neural voice model, encoded small enough to keep the app download light.
- Timing computed from narration timestamps so images and captions land on the right sentence.
- Marketing video produced in code from the same assets, with speech-to-text used to align captions.
- Engineering done with AI coding agents under a written architecture guide, with me reviewing every change.
The model drafts, the editor decides. Every story still gets a human pass before it ships.
Growth engine
The data was clear early: most installs come from people searching the App Store. That made distribution a search problem, so I work it from two sides.
- App Store Optimization: keyword research drives the name, subtitle and keyword field, localized per English-speaking storefront, plus redesigned screenshots and an app preview video.
- SEO content: more than 90 pages on histiaapp.com answering real history questions, each leading to a story you can play in the app.
- Short-form video: organic TikTok carousels and videos, measured series by series; what doesn't convert gets cut.

I wrote up two parts of this in detail: the AI content pipeline and the ASO playbook.
What I'd tell another founder
Pick the distribution channel before you build the feature list. Histia's roadmap is shaped as much by what people search for as by what they ask for. That's the lens I bring to every app audit.
