Haekka is the other genuinely Slack-first training tool worth evaluating alongside Poplearn, and the split between them is unusually clean: Haekka is a compliance product, Poplearn is a training product.
At a glance

Where Haekka is strong
Haekka is Slack-first in a strong sense — employees complete entire trainings, including video content, directly inside Slack without leaving the platform. Video inside Slack is a harder problem than text modules and Poplearn doesn't attempt it.
Its focus is mid-to-large enterprises with compliance obligations across HIPAA, SOC 2, GDPR, and PCI, with cited customers including Atlassian, Framer, and Jane. That's a specific and demanding buyer, and the product is shaped around passing audits rather than general education.
It offers three delivery modes: custom training your organisation authors, Streams of pre-built subscription content, and lightweight Pulse quizzes. Pre-built compliance content is the part worth weighing carefully — writing HIPAA training yourself is slow and getting it wrong has consequences, so subscribing to maintained content is often the correct call. Haekka also runs phishing simulations that route failures into Slack-based just-in-time training, closing the loop between test and remediation.
Where Poplearn is different
Poplearn has no compliance content library. It converts what you give it.
/courses new takes a document you already have and splits it into modules with quizzes written automatically. /assign #support sends it to a person, a channel, or every new hire going forward. /progress gives live completion by team, exportable the moment an auditor asks — a per-person, timestamped record rather than just a percentage.
That record is genuinely useful for compliance, but it's the evidence layer, not the content. If you need someone to have written correct HIPAA training, Poplearn doesn't provide that and Haekka does.
Poplearn is general-purpose in exchange: onboarding, internal process, product knowledge, policies — anything you have a document for, not just regulated topics. And it's free under 20 seats.
Which one fits your team
Choose Haekka if you have named regulatory obligations, want maintained compliance content rather than writing your own, or need phishing simulation tied into training.
Choose Poplearn if your training is broader than compliance, the material is company-specific and already written, and what you need is delivery plus a defensible completion record.
