Ninjō AI vs Relay.app Agents: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Ninjō AI and Relay.app Agents — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Ninjō AI
Ninjo
Infrastructure for AI sales agents on Instagram, WhatsApp and other DM channels, built and improved by talking to an LLM over MCP.
Key features
- MCP Server Control Surface: Exposes agent creation, testing, analysis and improvement as MCP tools, so Claude, Claude Code, Codex or ChatGPT becomes the interface instead of a dashboard.
- Cortex Playbook Library: Ships prompt templates, KPI rubrics and anti-patterns distilled from agents that ran in production, so a new agent inherits patterns that already converted rather than starting blank.
- Multi-Channel DM Deployment: Connects agents to Instagram, WhatsApp and other direct-message channels where the selling actually happens, without a separate build per channel.
- Versioned Changes with Rollback: Every edit to an agent is versioned and instantly reversible, so a bad prompt change during a live launch can be undone rather than debugged under pressure.
- Synthetic Conversation Testing: Runs an agent against generated conversations before it reaches a real inbox, surfacing broken qualification logic ahead of launch.
- Follow-Ups and Keyword Triggers: Fires scheduled follow-up sequences and keyword-based branches so stalled conversations get reopened automatically.
- Built-In CRM and Funnel Analytics: Ninjo Studio provides real-time conversation views, contact records and funnel reporting in one panel for when you want direct oversight.
- Payment Recovery Flows: Agents can chase declined payments conversation by conversation, a pattern the team credits for recovering 47 declined payments in a single four-day launch.
Best for
- Creator and Coach Launches: Running a short high-volume launch where an agent qualifies inbound DMs, handles objections and sends payment links at a pace a human team cannot match.
- Instagram Lead Qualification: Filtering hundreds of daily inbound Instagram messages down to the prospects worth a human sales call.
- WhatsApp Sales Follow-Up: Reopening conversations that went quiet with timed follow-up sequences instead of leaving them to decay.
- Agency Multi-Client Operations: Managing many client agents from a chat interface so a three or four person team can operate over a hundred agents.
- Declined Payment Recovery: Having an agent work through failed transactions individually to recover revenue that would otherwise be written off.
- Rapid Agent Iteration: Rewriting an agent's qualification logic mid-campaign and rolling back immediately if conversion drops.
Relay.app Agents
Relay (relay.app)
No-code platform to build and run autonomous AI agents that automate tasks across Gmail, Notion, HubSpot and hundreds of other apps.

- Proactive Background Agents: Agents can run continuously or on schedules to monitor inboxes, databases, or other sources and take actions autonomously day and night.
- LLM Backend Support: Integrations with large language models such as GPT-4 and Claude (reported in third-party sources) to enable natural language understanding, generation, and complex decision logic within agents.
- Human-in-the-Loop Controls: Options to pause workflows for human review, approve outputs, or intervene in agent decisions to maintain quality and compliance.
- Templates for Common Tasks: Ready-made templates for use cases like lead enrichment and customer support that reduce setup time and provide best-practice starting points.

- Email Automation and Summarization: Continuously monitor Gmail, summarize long threads, and generate suggested replies or follow-up actions for faster inbox management.
