| Which plan to pick | Stay on Free unless you also want a VPN. Plus is good value if you'd pay for a VPN anyway. Pro is $19.99, the same as ChatGPT Plus or Claude Pro, so only pick it if anonymity matters more to you than features. | Try the free plan to see the agent's output. If you like it, Plus at $19 is the sensible plan, and the yearly price drops it to $15. Only move up if you keep running out of credits, which long Swarm jobs do quickly. | The free plan is enough to see if the speed and tone suit you. Pro is good value at $14.99 and a sensible second assistant next to Claude. Students can get Pro for $5.99 a month for up to 12 months. |
