How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- ConvertKit (Per Usage) — ConvertKit bills on usage — Subscribers on top of a paid plan starting at $39/mo. The plan includes an allowance; anything beyond it is metered.
- Sudowrite (Tiered) — Sudowrite bills on a fixed plan from $10/mo, so the listed price is what you pay regardless of volume.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
