Sticker Generator - One Character, Twenty Expressions, Perfect Consistency#

One character. Twenty expressions. Every sticker looks like the same person. That's the hard part — and that's what CellCog does better than anyone.

Generating one cute sticker is easy. Every AI tool can do that. But generating a complete pack of 20 stickers where the character has the same face, same style, same proportions — just different expressions and poses? That's consistency at scale, and it's where most AI tools completely fall apart. By sticker #10, your character looks like a different person.

CellCog maintains character identity across every single generation, delivers with transparent backgrounds, and packages everything for your target platform — WhatsApp, Telegram, Discord, Slack, or iMessage.

How to Use#

For your first CellCog task in a session, read the cellcog skill for the full SDK reference — file handling, chat modes, timeouts, and more.

OpenClaw (fire-and-forget):

python

result = client.create_chat(
    prompt="[your task prompt]",
    notify_session_key="agent:main:main",
    task_label="my-task",
    chat_mode="agent",
)

All agents except OpenClaw (blocks until done):

python

from cellcog import CellCogClient
client = CellCogClient(agent_provider="openclaw|cursor|claude-code|codex|...")
result = client.create_chat(
    prompt="[your task prompt]",
    task_label="my-task",
    chat_mode="agent",
)
print(result["message"])

Why Sticker Packs Are Hard#

The challenge isn't making one sticker. It's making twenty that look like they belong together.

Choosing Mode & Tier#

ScenarioRecommendedSticker packschat_mode="agent" (defaults to the "flash" tier)Brand sticker systems, very large sets (30+)chat_mode="agent", chat_tier="max"

The flash tier is the default and handles most sticker generation well — fast and economical. Upgrade to chat_tier="max" when quality disappoints or the work is genuinely complex: just re-run the same prompt with chat_tier="max".

Agent Team ( chat_mode="team") is reserved for deep research — don't use it for sticker generation.

Tips for Better Sticker Packs#

1. Describe the character in detail: "Orange cat" is vague. "Chubby orange tabby with green eyes, white chest patch, round face, always slightly smug expression" gives CellCog what it needs for consistency.

2. Plan your expressions upfront: List all the expressions you want before generating. This helps CellCog plan the full set and avoid drift.

3. Specify the style clearly: "Kawaii", "flat design", "chibi anime" — one clear style direction keeps the whole pack cohesive.

4. Include reference images when possible: If you're making stickers from a pet photo, mascot design, or existing character, upload the reference. CellCog uses it to maintain likeness.

5. Think about readability at small sizes: Stickers are viewed tiny. Bold outlines, simple shapes, and clear expressions read better than detailed illustrations.

6. Platform first: Different platforms have wildly different requirements. "For WhatsApp" vs. "For Discord" changes dimensions, format, and file size targets. Always specify.
