Resume & Cover Letter - AI Resume Builder Powered by CellCog

7 seconds. That's how long the average recruiter spends on your resume. CellCog makes every second count.

#1 on DeepResearch Bench (Apr 2026) — CellCog researches your target role, understands what hiring managers look for, optimizes for ATS systems, and generates beautifully designed resumes — PDF for polished presentation or DOCX when ATS systems require Word format. Not another template filler — a research-first resume engine.

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 CellCog for Resumes?

Generic Resume Builders	CellCog Resume Cog
Pick a template, fill in blanks	Researches your target role first
Same advice for everyone	Tailored to specific companies and industries
Basic ATS keyword stuffing	Deep understanding of what ATS systems scan for
Template designs	State-of-the-art PDF generation, custom every time
Text only	Can include charts, visual elements, custom layouts

Choosing Mode & Tier

Scenario	Recommended
Resumes and cover letters	`chat_mode="agent"` (defaults to the `"flash"` tier)
Career strategy with multiple role-specific variants	`chat_mode="agent", chat_tier="max"`

The flash tier is the default and handles most resume work 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 resume work.

Tips for Better Resumes

Provide real details: Don't say "I worked on projects" — give specific metrics, tools, and outcomes. CellCog can't invent your achievements.
Name the target role: "Resume for a PM" is vague. "Resume targeting Senior PM roles at B2B SaaS companies in fintech" gives CellCog direction.
Include metrics: Revenue numbers, user counts, percentage improvements — quantifiable results make resumes stand out.
Specify design preferences: "Modern and minimal", "traditional corporate", "creative with color" — or let CellCog choose based on your industry.
Choose your format: PDF is the default for polished, presentation-ready resumes. Request DOCX when you need to edit or when ATS systems require Word format.
