A browser-based, chat-driven AI video editor (formerly Podcastle) where you describe edits in plain language — cut filler, sync to music, clean audio, caption, and clip — with access to 100+ generation models including Kling, Sora-2, Veo 3.1, and FLUX.2 built in.

Async is a chat-based AI video editor that runs in the browser. Instead of a timeline-first interface, you open a project chat and tell it what you want — "cut the dead air," "pull three vertical clips," "clean up the audio," "add captions" — and it performs the edit. It is the product formerly known as Podcastle, rebranded to Async in early 2026 when the company moved from a podcast-focused audio studio to a general AI video editor; podcastle.ai now loads as Async.
The editing core handles the repetitive work: removing filler words, pauses, repeats, and bad takes; syncing cuts to music; cleaning audio with a "Magic Dust" noise-removal tool; generating AI subtitles; and finding the strongest moments in a long recording to turn into short-form clips sized for TikTok, Instagram Reels, YouTube Shorts, and LinkedIn. You can save a reusable "skill" that captures an editing style and apply it to future projects.
In March 2026 Async added access to over 100 AI models inside the workspace, so you can generate assets without leaving a project: video via Kling, Sora-2, and Veo 3.1; images via FLUX.2, Nano Banana, and Gemini; plus avatars, music, sound effects, and voiceovers from a library marketed as 1,000+ AI voices with multilingual narration and AI dubbing. Templates cover reels, quote videos, brand intros, and welcome videos. One boundary is worth stating plainly: Async's workflow ends at export. It sizes clips for social platforms but does not post or schedule them, and it does not generate brand-exact carousels, blog articles, or email newsletters from the same source.
Think of Async as the place you manufacture the raw material and Kompozy as the place you turn that one asset into a week of published content. Async is unusually good at the make step: you generate a Sora-2 or Veo 3.1 clip, pull verticals from a long recording, and polish it all by chatting — and then it hands you an export. That export is a dead end for distribution. Async formats clips "for" TikTok, Reels, Shorts, and LinkedIn, but it does not publish to any of them, and it produces nothing outside video. That is precisely the gap [Kompozy](/) fills.
Drop an Async export into Kompozy as a source and the single video becomes many on-brand pieces. Kompozy [reframes](/glossary/clipped-short) and re-captions it per platform with your own caption style, and if you brought in long footage it runs its own clip detection to pull more shorts. From that same source it then generates the formats a video editor can't touch — brand-exact [Carousel Posts](/glossary/hyperframes) and quote graphics, a [blog article](/glossary/content-repurposing), an email newsletter, and an avatar-narrated [Persona Short](/glossary/persona-shorts) — all governed by a [Persona Brief](/glossary/persona-brief) so a batch reads as one brand. Then [Autopilot](/glossary/autopilot) schedules and publishes the whole set across the eight social platforms plus blog and email from one queue, behind a per-post review gate. Async generates and edits the hero clip; Kompozy multiplies and ships it. See also the honest [Async review](/reviews/async) and the [Async alternative](/alternatives/async) breakdown.

No. Async sizes and formats clips for TikTok, Instagram Reels, YouTube Shorts, and LinkedIn, but its workflow ends at export — you download the finished video and post it manually. To auto-publish one clip across platforms and turn the idea into carousels, a blog, and a newsletter, bring the export into a content engine like Kompozy, which fans output to the eight social platforms plus blog and email from one queue.
Export your edited clip from Async and bring it into Kompozy as a source. Kompozy reframes and re-captions it per platform, runs clip detection on any long footage for more shorts, and generates net-new formats from the same source — carousels, quote cards, a blog article, a newsletter, and an avatar Persona Short — all under one Persona Brief, then schedules and publishes them on autopilot.
Async has a free tier with a small lifetime credit allowance, limited storage, and 720p exports, plus credit-based paid plans (an entry individual plan, a most-popular Pro plan, a team plan, and a custom Business tier). AI generation burns credits faster than simple edits, and headline prices are usually the annual-billed rate, so check async.com/pricing for current figures.
