Bottom Line

Last reviewed: August 2026

Async and Krisp both compete in Audio, overlapping most directly on audio. Krisp carries the higher rating (4.7 vs 4.4), but a gap that size rarely overrides a real workflow fit on its own.

Choose Async if…

Best for podcasters and video creators who want recording, editing, chat-directed repurposing, and publishing handled in one browser-based tool, and its edge is rebranded from Podcastle to Async, a chat-based video and audio suite that retains Magic Dust for one-click filler-word removal, audio leveling, and noise cleanup. A genuine time-saver for quick podcast editing, Descript still wins on detailed word-level control. Lean toward Krisp instead if noise suppression runs locally on-device, filtering both your mic input and what you hear from others matters more for your use case.

Choose Krisp if…

Best for anyone taking calls from a noisy environment who needs to sound clear on the other end, and its edge is noise suppression runs locally on-device, filtering both your mic input and what you hear from others. Worth it the first time a client hears your background noise disappear mid-call. Lean toward Async instead if rebranded from Podcastle to Async, a chat-based video and audio suite that retains Magic Dust for one-click filler-word removal, audio leveling, and noise cleanup matters more for your use case.
