# AI Research Brief — Petri's Apps
## For journalists and writers using an AI assistant

---

If you're using an AI assistant (Claude, ChatGPT, Perplexity, etc.) to research these apps before writing, paste the prompt below along with the URL list. Most AI tools can only fetch URLs that are given to them explicitly — this brief solves that.

## Prompt

---

Please fetch each of the URLs listed below and read them fully before responding. Then give me a comprehensive research brief on the developer Petri Kajander and his three iOS apps — Lappaa, Nuotit, and Nootti — covering:

1. What each app actually does, in plain language
2. Who each app is built for and what problem it solves
3. How each app has evolved since launch (version history, notable additions)
4. What makes each app genuinely different from its closest competitors
5. The technical architecture they share (on-device AI, privacy stance, no cloud accounts)
6. Petri's background as a founder and how it connects to what he builds
7. Any press coverage or notable moments

Use the fetched pages as your primary source. Where pages contradict each other (e.g. an older blog post vs a current .md file), treat the .md file and current App Store listing as authoritative. Do not summarise from memory — read the pages first.

- `lappaa.com/lappaa.md`, `nootti.com/nootti.md` and `nuotit.org/nuotit.md` are the most detailed technical references for those three apps — fetch these first.
- The blog posts at petrikajander.com describe the original launch context but the apps have been updated significantly since — use them for origin story and founder voice, not current feature state.
- `docs.nootti.com` has the most complete Nootti feature documentation.
- The App Store pages show current version numbers and recent changelog entries.
