Jason AI, from Reply.io, functions as an autonomous AI sales development rep: it writes personalized outbound sequences, handles prospect replies conversationally, and books meetings directly onto a rep's calendar without a human managing every step.

Give Jason your ideal customer profile and messaging guidelines, and it drafts multi-touch email and LinkedIn sequences, then when prospects reply, it engages in natural back-and-forth conversation, handling objections and scheduling logistics, escalating to a human only when a conversation needs judgment Jason isn't confident making. Because it is built on Reply.io's established sales engagement infrastructure, it integrates with existing CRM and calendar tools rather than operating as an isolated experiment.

Who is it for?

Sales teams wanting to scale outbound without proportionally scaling SDR headcount, and revenue teams testing AI-led prospecting before committing to a larger AI sales stack.

How much does Jason AI cost?

Pricing is bundled into Reply.io's sales engagement plans, with AI SDR functionality as a premium tier, quoted based on team size and sequence volume.

Our verdict

Jason AI's autonomous conversation handling, not just sequence generation, is what separates it from simpler AI email writers. For teams ready to let AI own real prospect conversations, it is one of the more mature options built on proven sales infrastructure.
