Head-to-Head
Category | Notis | Relay.app |
---|---|---|
Voice capture (WhatsApp/Telegram) | First-class: record/send voice notes via WhatsApp/Telegram; 56+ languages; auto-file to Notion; reminders back in chat | Not chat-first; can integrate messaging apps (Slack, email, WhatsApp via connectors) but no native “voice-to-assistant” UX focus |
Notion integration | Deep, bidirectional; optimized for complex templates, databases, properties; “Second Brain” template included | Robust Notion connector with triggers/actions; great for automating around Notion inside larger workflows |
Tasks & reminders | Create tasks by voice/text; remind via WhatsApp/Telegram/email; query tasks by project/place | Tasking via app actions (e.g., Slack reminders, task apps); approvals/human-in-the-loop in workflows |
Web search & RAG | Built-in web/deep research that saves structured results into Notion | AI steps (summarize/extract/generate) within flows; not positioned as a research assistant per se |
Automations/follow-up | Webhooks + recurring automations, email follow-ups; lighter-weight, natural language-driven | Core strength: rich triggers/actions, branches, subflows, approvals, deep app coverage |
Pricing | Pro 16/mo; Pro+ 48/mo; Ultra $160/mo (monthly), 7-day trial; annual discount | Free (1 user/200 steps); Pro 19/mo; Team 69/mo (10 users/2,000 steps); Enterprise custom |
Security & compliance | GDPR posture; encryption in transit/at rest; Google API Limited Use; no public SOC 2 | SOC 2 Type II; GDPR/CCPA data rights; SSO (Google/Microsoft); enterprise options |
