# Plans, AI usage, and why we charge

> What AI usage measures, what Free gives you, what paid plans add, and why a hard limit exists.

Every reply in Lunafic is real work on real computers. The model that reads your world, holds the scene in mind and writes the next page runs on GPUs, and GPU time costs money. AI usage is the meter for that work, so you can always see what remains.

We measure usage and not a count of stories, because every world is a different size. A quiet two-character story and a deep world with a full stage count the same on a story counter. The meter measures what the AI actually reads to answer you.

## What Free gives you

- 20,000 AI usage every month.
- The Quill model.
- Up to 50 entries in your Wiki.

There is no limit on how many stories you start. AI usage is the only meter. If you write a few nights a month, Free may be enough for a long time.

## What paid plans add

- **More AI usage every month. **More scenes and longer sessions.
- **A deeper model. **Compass, with a 5-hour and a daily limit. That is about 85 Compass messages every 5 hours, and about 170 a day. Longer replies and longer stories use it faster.
- **A bigger story memory. **The AI remembers more of a long story. Extended memory on Ultra and Ultra+ holds up to twice as much as Plus.
- **Compass memory. **Ultra and Ultra+ can pick Compass for memory notes.
- **No Wiki entry limit.**
- **The Memory dialog, search, and Find and replace. **On Free the memory still works on every reply, and these three tools open on paid plans.

## Why Compass has limits

A Compass reply costs about 6 times a Quill reply. A few very long sessions were using much more than a plan pays for. The 5-hour and daily limits keep Compass open for every player without raising plan prices. When you reach one, Quill and Claude keep working, and the picker shows when Compass is back. More models are coming soon, with more choices on every plan.

## Why there is a hard line

Many platforms soften their limits and hide the bill, with slower speeds and shorter replies. We chose to say it plainly. When your AI usage runs out, writing pauses until the month resets or you upgrade, and the story stays exactly where you left it. We show no ads, we do not train on your stories, and we do not sell data.

## Upgrade, downgrade, cancel

Upgrade from the pricing page or the upgrade button inside the app. AI usage resets every month, and billing shows the reset date. If you downgrade or cancel, your stories stay yours, and you can export them whenever you want.
