Raena AI surprised us when we first graded it. Underneath a surface of podcasts, study games and literal brainrot videos, there are two genuinely good practice features: AI-graded free-response questions, and an exam mode that withholds feedback until the end the way a real exam does.
The problem is not what Raena does in the moment. It is that none of it seems to remember you the next day.
Raena AI
Nine study formats generated from one upload
- Price
- $13.99/mo$83.99/yr
- Free
- Free tierAdvertised, but the store lists features as subscription-only

- AI-graded free-response questions, which is real retrieval practice
- An exam mode that withholds feedback until the end
- Study games, podcasts and voice-recorded lecture capture on mobile
Beats Akono at
- Free-response grading, which most of this category does not attempt
- A proper exam mode, closer to the real thing than competitors manage
- More formats from one upload than anything else here
- Genuinely engaging if you respond well to gamified short bursts
Where it falls short
- Your mistakes do not carry over. Every session starts from zero
- Quiz results do not feed back into anything, per independent reviews
- The site advertises a free plan; the App Store lists the features as subscription-only
- Its terms state subscriptions are non-refundable
- Reviewers report being charged on a cadence they did not expect
Akono
One loop that works, instead of nine formats that might
- Price
- €11.99/mo€59.88/yr
- Free
- Free trial3 days, card required
What you get
- One loop rather than nine output formats, and no games or brainrot videos
- Every session ends with you having produced answers, not consumed material
- Misconceptions are recorded per concept and reopened later
- A study plan that runs back from your exam date
Beats Raena AI at
- What you got wrong last week is the thing next week is built around
- Misunderstandings stay open across sessions until you can explain them
- The study plan re-composes around your exam date every time you open it
- One tutored format rather than nine surfaces that do not talk to each other
Where it falls short
- No games, no mindmaps, no podcast. One format, not nine
- No free tier. Three days of the whole product, card required
- Less immediately fun. A session asks you to sit down and think
- If your exam is tomorrow, use something else
How Akono is different from Raena AI
Raena grades a free-response answer properly, which is more than most of this category attempts, and its exam mode withholds feedback the way an exam does. Both are real.
What happens afterwards is nothing. The tutor chat does not know what you got wrong yesterday, and independent reviews confirm quiz results do not feed back into anything. Every session starts from zero.
That is the difference. Raena grades the answer and forgets it. Akono grades the answer and builds next week around it.
A blank slate every session
Raena AI
You answer
Your free-response answer is graded and marked down.
What happens
You see the grade. Nothing records what the gap was.
Next time
A fresh session that has no memory of yesterday.
One loop, repeated until it sticks
Akono
You pick
Nothing. There is no menu of nine formats to choose between.
What happens
You get asked something, and what you answer decides what comes next.
In between
The gap gets taught immediately, in the same session.
Next question
Aimed at that gap. The loop does not change because the loop is the product.

Raena is stronger in the moment than its reputation suggests. The split is entirely about what survives to the next session.
