AI Tool Comparison
Async vs Krisp
A side-by-side breakdown to help you pick the right tool for your workflow.
Async
Async (formerly Podcastle): a chat-based AI suite for recording, editing, and repurposing podcasts and video, still including one-click filler-word removal, audio leveling, and AI voice cloning.
Krisp
Strip background noise and accents out of calls in real time, with AI meeting notes and call-center agent assist layered on top.
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.
