What Kyra is
A privacy-first trading journal for iOS focused on equities. Pattern detection runs on-device. Every pattern shows its sample size and an uncertainty range — the four tiers (Tracking, Hint, Signal, Proven) sharpen as your history grows, so claims stay honest about how much evidence supports them. Primary buyer: a retail self-executor who wants the gap between strategy and execution made visible. $4.99/mo or $39.99/yr after a 7-day trial.
What Debrief is
Debrief is a voice-first iOS journal. You tap a mic, talk through your session for up to two minutes, and server-side AI turns the recap into a structured entry. It is account-based: you sign up with an email, and your voice and notes are processed on its servers. Debrief surfaces a single 0–100 "Debrief Score" across four pillars and a weekly AI narrative review called "The Brief." Debrief Pro is $9.99/month or $99/year; the free tier includes unlimited manual entries and three voice entries.

Who should pick which
Pick Debrief if:
- You would rather talk through a trade than type it, and want AI to structure the recap
- You want a weekly AI narrative coach
- You want an equity-curve chart out of the box
- You are comfortable with an account and cloud processing of your notes
Pick Kyra if:
- You want your trade data to stay on your device, with no account to create
- You want every pattern claim to show its sample size and an uncertainty range
- You would rather the journal stay an observer than a coach that grades your trades
The trade-off
Debrief's voice capture is genuinely lower-friction for traders who think out loud, and it ships an AI coach and an equity curve that Kyra does not. Those are real reasons to choose it.
The difference underneath is architectural. Debrief sends your voice and notes to a server, where AI structures them and computes a score that unlocks at five entries. Kyra runs its analysis on your device, asks for no account, and won't call a pattern Signal until the evidence is there. One product is built around a cloud assistant; the other around keeping the record yours. Read more on why Kyra stays on-device and the security model.
