ArcLab builds toward the single worker, alone, finishing one training objective on a link, no account required.
Quick verdict
Pick ArcLab if
you want browser-based delivery over WhatsApp or SMS with zero app download, and the priority is turning existing SOPs into training fast.
Pick Gnowbe if
you want cohort-based, social learning: peer discussion, group challenges, and a dedicated learner app with 10+ interaction types, now positioned around measurable execution and alignment.
Evaluate both if
you want AI-authored content and rich social/collaborative learning in the same programme. Weigh how much of that your team will use.

Pro is self-serve with no published price; Business and Scale are sales-gated ("Connect with a growth expert")
Pricing approach
Free up to 25 learners (Basic) · $2-4/learner/month billed annually, or $3-5/active learner/month with no commitment (Pro) · Custom, quoted per organisation (arclab.io/pricing, checked 8 Sep 2026)
No public dollar figures anywhere on gnowbe.com/pricing as of 11 Sep 2026, for any tier; Pro is capacity-gated (up to 2,000 AI tasks, 100 users) rather than price-gated
The real difference
Gnowbe is built for programme-based learning: a multi-day arc with peer discussion, group challenges, and 10+ interaction types authored by AI from a prompt or a document, now framed as an enterprise "execution and alignment" system rather than a learning platform. That's a genuinely different shape of experience, closer to a structured performance programme than a single lesson.
ArcLab is built around the single learning objective: one thing, 2 to 10 minutes, done alone, on a link. It won't replace a cohort programme or an enterprise alignment system. Its job is getting one fact or one procedure into one worker's head, fast.

Where ArcLab is strong
A stricter definition of "nano": one learning objective, 2 to 10 minutes, no cohort or programme structure required around it.
Genuinely no account: Gnowbe's browser option still needs a login. ArcLab's link doesn't.
Fast from existing documents: SmartTransform converts an SOP or deck straight into a module in minutes, without authoring a multi-action interactive session first.
A training record that doesn't depend on SingPass: with no account to create, each worker's record is tied to their own link, with no SingPass login needed.
Published pricing, no capacity puzzle: ArcLab's rates are public per learner. Gnowbe's tiers are now gated by AI-task and user capacity with no listed price at all, even on its self-serve Pro tier.
Where Gnowbe may be the better fit
You want live cohort experiences with peer discussion and group challenges, not solo micro-modules.
You'll use 10+ varied interaction types, like role play and reflection journals, rather than a focused knowledge-check set.
You're buying into an enterprise execution/alignment system, not just training, and want AI agents, HRIS/CRM integration, and enterprise analytics as part of one platform.
Use-case fit
Where teams use ArcLab today: construction (Woh Hup, a major Singapore firm, has used ArcLab since 2021 for Workplace Safety and Health training), and F&B/retail (4Fingers, a multi-outlet chain; Polar Puffs & Cakes, using ArcLab for training, assessment, and outlet-audit modules). Gnowbe publishes a CityMart retail case study. (arclab.io/showcase, gnowbe.com/case-studies/retail)
Implementation and adoption
Gnowbe's admin experience now centres on its AI Agents and a behavioral-design engine for building multi-action programmes. ArcLab's rollout is simpler by design: no app, no cohort to schedule, no admin course-builder to learn first, with optional geofencing where access needs to be locked to a work site.
Proof
Woh Hup, a major Singapore construction and civil engineering firm, has used ArcLab since 2021 for Workplace Safety and Health training delivered to migrant workers in their native language, extending to QAQC training in 2023. 4Fingers, a multi-outlet F&B chain, digitised its SOPs with ArcLab after binder-based training became too costly to update across outlets. (arclab.io/showcase) ArcLab states its customers save more than 50% of training time per staff per month, a vendor-stated figure, not independently audited. (arclab.io)
Pricing
ArcLab's published pricing (arclab.io/pricing, checked 11 Sep 2026): Basic is free for up to 25 learners (ad-supported, limited modules, email invites only). Pro is $2-4/learner/month billed annually, or $3-5/active learner/month with no annual commitment, and includes full assessments, unlimited modules, WhatsApp/SMS/email invites, and exportable analytics. Custom is quoted per organisation and adds training-needs analysis and a dedicated customer success rep.
Gnowbe's pricing page (gnowbe.com/pricing, checked 11 Sep 2026) no longer lists any dollar figures for any tier. Pro is self-serve ("Get started with Pro") with capacity for 100 users and up to 2,000 AI tasks a month; Business and Scale require talking to a "growth expert."
Frequently asked questions
Does ArcLab need an app?
No. It runs from a secure web-link sent over WhatsApp or SMS.
Isn't Gnowbe's web app the same thing?
Not quite. Gnowbe's web app still needs an account and a login. ArcLab's link doesn't ask for either.
How many languages does ArcLab support?
ArcLab's SmartTranslate instantly translates modules on demand rather than publishing a fixed language count. Gnowbe now states 70+ languages consistently across its site.
Can we use our existing SOPs or training decks?
Yes, that's the starting point for building a module with SmartTransform.
Do we need to run cohorts or groups to use ArcLab?
No. Delivery is one-to-one: each worker gets their own link and works through it alone.
