The Verdict
Lark is built for startups and asian market teams, with a focus on messaging and video-conferencing. Spark targets professionals and small teams and leads with smart-inbox and ai-writing.
Pricing is close: Spark starts at $7.99/mo versus $12/mo for Lark — not a deciding factor on its own.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
