Where they actually diverge

The differences that matter once you start using either tool.

What the agent does

Tulsk

Tulsk's agents do whatever you teach them with a Markdown skill — research a market, draft copy, run web searches, generate reports, ship code. The runtime is general-purpose.

Cosine

Cosine's Genie is purpose-built for engineering. It scopes work, decomposes tasks, runs in your local environment, and opens PRs. Cosine claims a 72% pass rate on the SWE-Lancer benchmark.

Pricing shape

Tulsk

Tulsk meters by runs — 50 on Free, 500 on Pro. Seats are $7 per extra seat per month. Predictable. Unused runs don't matter; the next month resets.

Cosine

Cosine meters by tokens. Hobby is $20 per seat for 5M tokens. Professional is $200 per seat for 60M. Unused tokens don't roll over. Top-ups available at the same rate.

Data sovereignty

Tulsk

Tulsk is cloud-hosted. Enterprise has VPC and dedicated options under contract.

Cosine

Cosine Enterprise goes further than most: cloud, single-tenant cloud, VPC, or fully air-gapped on-prem with customer-owned GPU weights and zero data egress. If your industry forces air-gap, Cosine has the strongest story here.

The fit test

Which one are you?

Pick Tulsk if you…

  • Your team's bottleneck spans more than code
  • You want PM and agents in one place, with a free tier
  • Token-metered pricing makes you nervous
  • You want an AI project manager (EMA) watching scope and reports

Pick Cosine if you…

  • You only need a coding agent — no PM features
  • Air-gapped on-prem with your own GPU weights is a hard requirement
  • You want the agent to run in your real local environment, not a sandbox
  • Token transparency matters more than predictability
