Both tools write replies. Here's where they actually differ.
Rizz is reply-first: you upload a screenshot, you get a reply. TTfactory does the same — and adds a Profile Roaster, a Bio Generator, a Practice Mode, and a Conversation Tracker. If you only need replies, Rizz is fine. If you want the end-to-end dating workflow, TTfactory covers more ground.
Rizz sells weekly and monthly subscriptions. TTfactory has a free tier (one analysis per day, no card), a weekly Wingman plan at $9, and an unlimited Rizz Master plan at $39/month that includes the Conversation Tracker. Value per feature, TTfactory is cheaper at the annual level.
TTfactory runs on Claude Opus 4.6 on paid plans and Haiku 4.5 on free. We picked Claude because on human-voice writing tasks it consistently writes shorter, punchier, less-AI text than the alternatives. The difference shows up most in Bio Generator output.
