What is an AI OC maker?
An OC is an original character: someone you invent for a story, a game or a world of your own. An AI character generator translates visible details into images. A portrait is the starting point—not a finished backstory, a 3D model or a complete chat Character.
01 / Examples
Find a direction for your character
Explore six existing Lets Gen characters and the details that make their portraits recognizable. These are character-design references, not verified outputs of the current OC Maker. The practice prompts below were written for this guide; they are not the original image prompts and will not reproduce these portraits.
Selene Moon
Meet the character ↗Practice prompt
An adult astronomer with long midnight-blue hair, a crescent pendant and a navy robe. Quiet observatory, moonlit window, thoughtful expression, portrait.
Tessa Tempo
Meet the character ↗Practice prompt
An adult illustrator with orange double buns, freckles and headphones around the neck. Teal-and-orange jacket, warm daylight, cheerful illustrated portrait.
Kane Voss
Meet the character ↗Practice prompt
An adult spaceport guard with cropped hair, a weathered black jacket and a stern expression. Red industrial lighting, clear silhouette, cinematic portrait.
Sarah Vale
Meet the character ↗Practice prompt
An adult librarian with a short auburn bob, cream blazer and teal shirt. Gentle smile, bookshelves, soft window light, realistic portrait.
Morrow
Meet the character ↗Practice prompt
An adult gothic traveler with long black hair and a dark coat. Foggy old street, distant amber lantern, reserved expression, atmospheric portrait.
02 / How it works
How to create the character you imagined
- 01
Write the idea
Choose a role, a setting and three recognizable details. Describe visible features rather than asking the image to show an entire biography.
- 02
Set the visual direction
Open OC Maker, refine appearance and choose a style or an image you own as a reference. Reference mode uses a different workflow and cost; review the creator before generating.
- 03
Compare four portraits
Look for the silhouette, hair, outfit and expression you intended. Select the candidate that best fits your idea—not just the most detailed image.
- 04
Refine one thing at a time
Keep identity details in your prompt and change one variable, such as expression or clothing. Review every result; consistent identity is not guaranteed. Continue to Character creation when ready.
From a vague idea to a usable prompt
This is a writing exercise, not a before-and-after generation claim. Add observable details, then make one deliberate change.
Read the character-design guide ↗Starting idea
A fantasy courier.
A clearer direction
An adult sky courier with silver braids, amber goggles and a weathered brown flight jacket. An envelope pouch at the waist, calm expression, simple sky-blue background, waist-up character portrait.
Next iteration
Keep the silver braids, amber goggles and brown jacket. Change only the expression to a confident smile.
03 / Why Lets Gen
Why build your OC with Lets Gen?
Start with words
Describe the character in your own language; you do not need a finished drawing to start exploring.
Compare, then decide
Review four portrait candidates together instead of committing to the first image.
Keep developing the idea
Take a selected portrait into Character creation, or explore the separate image, video and voice tools.
Choose character details
Build a description with hair, eyes, clothing and accessory options instead of starting from a blank page.
Explore a visual style
Choose a style without a reference image, or use your own reference to guide the character's appearance.
Find a starting idea
Use Inspire in the creator for a random character direction, then make it your own.

05 / Use cases
Made for your next character idea
Stories & comics
Define your protagonist's silhouette, outfit and expression before planning a cast or comic panels. Use the portrait as a visual reference alongside your story notes.
Tabletop & game concepts
Design a portrait for a tabletop hero or NPC, then add their role and personality. The image is a concept reference, not a rigged or ready-to-play game asset.
Avatars & creative identities
Explore a profile portrait for your online identity. Check the face at small sizes and the avatar crop before sharing.

Explore tool07 / FAQ
Questions before you create
How do I generate a character I invented?
Describe the role, hair, outfit, expression and framing. Start from a practice prompt above, replace its details with your own, then compare the four results in OC Maker.
Do I need to know how to draw?
No. You can begin with text. A reference image is optional and must be one you have the right to use.
Can I use a reference image?
Yes. Select your own image in the creator. Reference mode differs from style-only generation, including cost; check the displayed settings before submitting.
How many images will I receive?
OC Maker requests four portrait candidates per run. Check the actual result if a generation finishes only partially.
Is OC Maker free?
Generation uses Gems. The creator shows the cost before submission; available balance, promotions and paid options depend on your account. Browsing this page does not spend Gems.
Can I keep the same character in every image?
Keep distinctive details stable and use an appropriate reference when available. AI results can vary; review faces, clothing and accessories rather than assuming perfect consistency.
Does generating a portrait create a chat Character?
No. Choose a portrait and continue into Character creation to add the profile and conversation settings.
Can I publish or use the result commercially?
Check the current Terms and applicable usage conditions. Make sure you have rights to reference images and avoid infringing someone else's characters, likeness or trademarks.
Which styles can I use?
Choose from the styles currently available in the creator. Adding a reference image disables style selection; the two modes guide generation differently.
Is OC Maker different from an AI character generator?
OC means original character. OC Maker is an AI character generator focused on exploring a character's portrait, with a next step for creating their profile.
Can I get a random character idea?
Yes. Open OC Maker and use Inspire to fill in a starting description, then adjust the appearance and traits before generating.
What size are downloads, and do they have a watermark?
Check the dimensions of the generated image before using it for print or a large layout. Download watermarking depends on your account's creative entitlements; do not assume every export is watermark-free.
