Notis vs Duet vs Junior

Verdict

Notis aside, Duet has the highest support score, 61% across all 33 rows, ahead of Junior at 58%.

Their strengths differ: Duet for combining AI agents with human checkpoints and Junior for controlling complex multi-step workflows.

The cheapest way in is Notis at Free–$149/mo, though its free plan only does part of the job.
