Best AI short form video editor: four tools by what they cut for you

Best AI short form video editor: the short answer

The best AI short form video editor for automatic edits in this table is Submagic Pro, $39 a month per member, billed monthly, as read on 5 October 2026. It removes silences and bad takes (mistakes and long pauses), cleans audio, adds zooms and suggests a hook title, an opening title for the first seconds. Opus Clip Starter is the lower-priced route: it lists filler and silence removal at $15 a month, billed monthly.

Submagic Pro: silences, bad takes, clean audio and zooms

Submagic Pro adds AI removal of silences and bad takes, AI Clean audio, which reduces background noise and improves speech, auto zooms, hook titles and Storyblocks B-roll, a premium stock library. AI auto captions stay on every plan, and Pro covers 40 videos a month of up to 5 minutes. Pro is $39 a month per member, billed monthly, or $23 billed yearly.

In Submagic's guide the silence and bad-take tools sit in the optional Trim step, before the captions are styled. How to remove silence from a video automatically walks through that step. Pick Pro when you want these edits in one plan and one editor.

Opus Clip Starter: silence and filler removal at $15 a month

Opus Clip's pricing page lists filler and silence removal and watermark removal on Starter, which is $15 a month on monthly billing only, with 150 credits a month. Its Speech Cleanup tool opens from the top left of the editor, and nothing is cut without your approval. Remove Pauses starts at a 0.5-second threshold that you can change with a slider.

Opus Clip's help article names no plan for Speech Cleanup. Pick Opus Clip Starter when the lowest monthly-billed price matters more than zooms and hook titles.

Kapwing and Descript: Smart Cut and Remove Filler Words

Kapwing's pricing page lists Smart Cut, which removes silences automatically, without naming a plan. Its help article adds a Silence Sensitivity slider and lets you keep any detected silence by clicking it. Kapwing Pro is $24 per member a month, billed monthly. Pick Kapwing when Smart Cut should sit beside subtitles on long videos.

Descript Hobbyist is $24 per person a month, billed monthly, and lists Studio Sound, Remove Filler Words and Create Clips among its AI tools. Its filler-word tool detects English transcripts only, and Shorten word gaps uses AI credits on current plans. Pick Descript for filler-word removal and clips from long recordings.

What Submagic Starter leaves out

Submagic's pricing grid shows a dash on Starter for AI silence removal, bad takes, filler words, clean audio and hook titles, so Starter is the captioning plan: silence removal needs Pro or Business. Starter is $19 a month per member, billed monthly. The Submagic pricing page lists both billing bases for all three plans.

Submagic's free trial covers three short videos with no credit card, and a subscription is what removes the watermark from downloads. Caption and clip tools are compared on the best AI video caption generator page.
