You don't read a finished manuscript from start to finish. A scene opens, you write what you say and do, and a character answers. That answer becomes the next scene. Two people can open the same work and walk away with different stories.

This post uses MYMI as the example. Four terms come up often there, so it helps to know them first.

How is it different from web novels and AI writing tools?​

The biggest difference is where you stand. With a web novel you are a reader following the plot the author chose. In AI interactive fiction you are the lead, acting inside the scene. It also does a different job from AI writing tools, even though the names sound alike.

A writing tool exists to hand you a finished draft. Interactive fiction exists for the experience of stepping into a story and dealing with its characters. "AI fiction" can mean either one, so it saves time to decide which you are looking for.

How does a scene unfold?​

On MYMI, a scene moves in this order.

1. Read the work's description and pick the scene to start from (the Intro).
2. When the intro appears, write your line or action and send it.
3. The character responds, and the story moves one step forward.
4. If the reply doesn't fit, regenerate the last reply or edit it yourself.

Wrap an action in asterisks and it shows in a different color from dialogue. The line below is an example made up for this post.

*opens the window and looks down at the alley* That sound just now. Did you hear it too?

If you can't think of what to say, you can send with the input box empty. The character then carries the story forward. This still counts as one message.

You can also choose how the story looks. The Novel view, which opens by default, runs narration and dialogue together as continuous prose, so the scene you built by chatting reads like a novel. If you prefer speech bubbles, switch to the Chat view. If you want to page through the scene with the art behind the text, switch to the 1:1 view. Whichever view you choose, it is the same conversation.

To switch views, tap the palette icon at the top right of the chat room and use the first row of UI Settings. There is also a Story view, which puts the art in the background and lets you read on as prose.

As of November 13, 2026, these are the numbers worth knowing on MYMI.

For where the buttons sit around the input box and under each reply, see Chatting in the guide.

What genres are there?​

Each work on MYMI carries genres chosen by its creator. In the Genres tab on Home you can pick one of 13 genres, including Romance, Fantasy, Wuxia, Sci-fi, Slice of life, Comedy and Mystery & thriller, and sort by Popular, Weekly popularity or Newest. Hashtags on each work tell you more about its mood and setting.

Genres and tags are only hints. Read the description and the intro, and pick a scene that makes you want to answer the first line. That is usually the easiest way in.

How do I start?​

1. Open MYMI in your browser. The Android and iPhone apps use the same account.
2. On your first visit, a prompt asks which characters you mainly want to see. Choose "Female characters", "Male characters" or "Show me everything", and Home adjusts to match.
3. Choose a work from the Picks, Ranking, Genres or Search tab on Home and tap "Start chatting".
4. Without logging in, you can try up to 5 messages. Regenerating a reply counts as one.
5. If you want to keep going, you can sign up right from that screen. Your trial chat moves to the new account, and from then on each reply uses Sparks, MYMI's in-app currency for chatting.

Creating your own persona and writing a User Note need a login. During the trial, pick one of the work's Recommended personas if it has any, or say who your character is in your first message.
