Chatting in FictionLab
Chatting in FictionLab is very easy, but this guide will explain every feature to allow you to maximize your roleplay experience!
The chat is between you and the AI. The AI acts as the other characters while you act as your own character or a pre-defined character, depending on the scenario settings.
You can write your responses to the input field at the bottom or choose from two suggested responses if you're too lazy to write your own. The suggested choices can be disabled from the light bulb next to the send icon.
At the top navigation bar, there are three buttons. The first one from the left is the sharing button which allows you to send the scenario to your friends. You can even share a private scenario, allowing people with the link to access it. The middle button is for favoriting the scenario. This makes it appear in the "Favorites" section on your user page. Favoriting scenarios allows you to find them easily.
The last button is the settings button. Clicking it will open a side menu with a bunch of settings allowing you to customize the chat to your liking.
LLM Model Selection
The LLM model selection allows you to choose between the AI models that FictionLab offers. Each model has a unique "personality" and writing style, so you can experiment with them and see what fits your roleplaying style the best. Below are all the current models:

Chat Response Settings
Stream Text Response - Enables a typing animation where the generated text is shown to the user in real time. With this setting enabled, the response will only appear when the response is completed.
Show Response Suggestions - Enables or disables the two pre-generated choices after receiving a response from the bot.
User Character
The user character is the character you, the user, will play as during the scenario. You can access the user character menu from the side menu and edit it as the story goes on.
Hovering over the user character cards brings up three dots. Clicking on these dots allows you to either delete or edit the character card.
User character cards should be written in the same way as normal character cards are. Describe the looks and personality in the description. More detail usually gives better results.
Free users are limited to 10 user character slots. FictionLab+ users have unlimited character slots.
Custom LLM Instructions
Custom LLM instructions are almost identical to custom instructions in the scenario creation page. You can use it to guide or instruct the AI to act how you want. Instructions should be clear and concise for the best results. The limit for Custom LLM Instructions for free users is 200 characters, and 1000 for FictionLab+ users.
Custom LLM instructions should be used to nudge the AI in a certain direction and deleted after the desired results are seen.
For example: "When Joe steps outside of his apartment, it will start raining."
Narration Voice Settings
The narration voice setting allows you to change the voice that reads messages when using the narration feature. You can activate narration by clicking on the speaker icon while hovering above the AI's responses.
Enabling the Auto-Play Voice Narration toggle will automatically start narrating the message after it has finished generating.
Translation Language Setting
The translation language setting allows you to choose between supported languages for the translation feature. After selecting a language, hover above the message you want to translate and click the translate icon at the bottom right corner.
Chat Font Size
The chat font size allows users to customize the font size of the messages in this specific chat window. It ranges from 20% all the way to 200%.
Response Typing Speed
The response typing speed allows users to customize the text typing animation speed. Do note that the typing speed is limited by the generation speed of the AI. At the fastest setting, it will write out the text at the same time as it's being generated. Larger speeds can lead to pauses between typing.
Chat Color Customization
The color customization settings allow you to customize the color palette of the chat exactly to your liking. You can select any normal hex color using the color palette.
Chat Background Style
Chat background styles allow you to customize the chat window to fit your roleplay better and make your roleplay more immersive. Free users have access to 7 backgrounds, while FictionLab+ users have access to over 40 different backgrounds.
FictionLab+ users can also upload custom backgrounds from their device.
FictionLab Chat Formatting
FictionLab uses a variety of different symbols to indicate different behaviors. For example, actions are usually wrapped in *asterisks* while dialogue is wrapped in "quotes like these". FictionLab also supports bold letters in AI responses. Bold text is activated with **double asterisks**. It is usually used to emphasize actions or dialogue.
For your own messages, normal text is usually considered dialogue, and asterisks are narration/actions. Do note that the AI is very lenient with formatting, so you can utilize pretty much any formatting style you prefer.
FictionLab Message Menu & Editing
Hovering over a message makes three vertical dots appear on the side of the message. Clicking on these dots makes a message menu appear. This message menu allows you to copy, edit, branch, rewind, and delete messages. You can also regenerate the message using this menu.
Editing the message allows you to change parts of the message to your liking. It can be used to change events that have happened during the roleplay and to drive the roleplay in a different direction. Use the previously mentioned formatting for best results when editing.
Messages can also be reported if you find them to break our TOS and guidelines. Our staff team will then review the message and take action if needed.
Chat Branching
Chats can be branched from the message menu by pressing "Branch From Here". This will create an identical chat session up to that point, so you can experiment with taking different paths in the roleplay.
Message Regenerating
Messages can be regenerated if you're not happy with the results. You can press the reload symbol that appears at the bottom of the message while hovering to regenerate the message. After regenerating, you can switch between the response versions using the arrow symbols at the bottom of the message box.
Exporting Chats
Users can export the chat from FictionLab by opening the chat settings menu and scrolling all the way down. There, you can select "Export as PDF" or "Export as JSON".
Slash Commands
FictionLab offers a slash command system to make using certain features easier and quicker. You can see all of the available slash commands by typing "/" in the chat input bar.
Renaming Chats
For Desktop: You can rename the current chat session by hovering over the chat button in the sidebar.
For Mobile: You can access the same rename menu by long pressing on the chat button in the Chats page and selecting "Rename Scenario".
Disabling Auto-Keyboard Popup
You can change the keyboard behavior when the response finishes generating through the settings menu.
Change Default Chat Settings
Users can adjust the default chat settings that are applied when they start a new chat from the settings menu. The settings are identical to the ones shown in the chat settings side menu.
