We build software that does one thing well. AI is an experienced helper: a reader and feedback giver in Punakynä, a coach in MarathonApp.

Punakynä

Manuscript editor for authors – with an AI beta reader

Write novels, short stories and other long texts scene by scene. Every change is saved to a version history, and when the text is ready for readers you get feedback fast – from people and from AI.

  • AI reads your manuscript. The review goes through structure, characters, plot and mood and points out where the story wobbles. You can also connect your own AI app (such as Claude) to read and comment.
  • Beta readers and commenters. Invite readers to comment and suggest changes. You decide what is accepted – nobody changes your text without your approval, and neither does the AI.
  • A calm place to write. Scene and chapter structure, focus mode and paragraph styles.
  • A finished book. Preview the manuscript typeset as a book, and export to PDF, Word, EPUB or InDesign.

On the web and as a Mac and Windows app. The desktop app works without the web service: your manuscripts stay on your computer, and go online only if you want to share the book with beta readers. You can always export a manuscript to Word or PDF as well. See the privacy policy and terms of use (both in Finnish).

MarathonApp

Training app for iPhone and Apple Watch – with an AI coach

A training plan toward your marathon and an AI coach that knows your training history and recovery and adapts the plan to how training actually goes.

  • Import past workouts, resting heart rate and heart rate variability (HRV) from Apple Health.
  • An assessment of your current fitness, the day’s training load and a week-by-week plan toward your goal race.
  • Apple Watch: GPS and heart rate, interval cues by heart-rate zone and audio, and post-workout heart-rate recovery.
  • The coach runs on your device. Optionally you can also use a cloud AI with your own API key.

Your health data stays on your device unless you choose to share it. The app is not a medical device and does not replace the advice of a doctor or a coach.
