How to start
Pick Claude from the model selector — Haiku for everyday work, or switch to Sonnet when a job needs more reasoning or a long document. Not sure which model to use at all? Brainiac is one of the options in the picker and will auto-select for you.
What Claude is good at
- Writing that reads well — drafts, rewrites, and edits with a natural tone.
- Long documents — summarize, analyze, or rework a file you upload.
- Coding — explaining, writing, and reviewing code with clear reasoning.
- Careful, step-by-step answers when you want the model to think things through.
Haiku covers most everyday work. Reach for Sonnet when the task is longer or more nuanced and the extra depth is worth a few credits.
Tips for better results
- Give context first. A sentence on who it's for and what "good" looks like sharpens the output.
- Upload the source. Attach the document or code rather than pasting fragments.
- Ask for the format you want — a table, bullet points, a specific length.
- Start free, upgrade as needed. Try Haiku first; move to Sonnet if the answer needs more depth.
Do I need a paid Claude account?
No. Claude Haiku is free and unlimited on Tusk Central AI. Claude Sonnet uses credits — you get a monthly allowance free, then optional pay-as-you-go. No subscription.
