What Is Cleanvoice AI?

Cleanvoice AI is an online tool that automatically removes filler words, mouth sounds, and silence from audio recordings. You upload an audio or video file, it processes the audio, and you download a cleaned audio file. It's used primarily by podcasters who want to reduce the manual editing time spent removing "um," "uh," "like," and dead air from their recordings.

Cleanvoice features:

• Removes "um," "uh," "like," "you know," and other common filler words
• Removes mouth clicks, stutters, and breathing sounds
• Removes silence gaps longer than a configurable threshold
• Works with audio files (MP3, WAV) and some video formats (MP4)
• Outputs cleaned audio file
• Browser-based - no app to install

Cleanvoice limitations:

• ❌ Outputs audio, not video - you still need a separate video editor
• ❌ No caption generation
• ❌ No direct social media export
• ❌ Cloud-based - requires uploading files
• ❌ $9/mo plan limits you to 10 hours of audio per month
• ❌ No iOS app - browser only

What Is BlitzCut AI?

BlitzCut AI is a native iPhone, iPad, and Mac app that edits talking-head video automatically. It identifies all silence and pauses in a video, removes them in one tap, then generates styled AI captions. The result is a finished video file ready to post - not a cleaned audio file that still needs further work.

BlitzCut AI features:

• ✅ Automatic AI silence removal from video files
• ✅ Configurable silence threshold
• ✅ AI captions with 95%+ accuracy
• ✅ Viral caption presets (word highlight, animations, color styles)
• ✅ 4K export, 9:16/16:9/1:1 aspect ratios
• ✅ Direct export to TikTok, Instagram, YouTube
• ✅ On-device - no upload, processes immediately

Filler Word Removal: How Each Tool Handles "Um," "Uh," and Pauses

Both tools reduce filler words and dead air, but they work differently.

Cleanvoice AI approach: Cleanvoice uses speech recognition to identify specific filler words ("um," "uh," "like," "you know") and removes the audio at those exact timestamps. It also removes silence. The result is a cleaned audio file - the corresponding video frames are not touched.

• ✅ Identifies and removes specific filler words by name
• ✅ Handles "um" and "uh" even within sentences (not just at sentence gaps)
• ✅ Configurable - can choose which filler words to remove
• ❌ Output is audio - video frames still need to be cut separately in another editor

BlitzCut AI approach: BlitzCut uses waveform analysis to detect silence - defined as audio below a set volume threshold for a configurable duration. It removes all identified silent gaps from the video, including pauses between words. Because it removes the video clip at each silence point (not just the audio), the output is a finished edited video.

• ✅ Removes all pauses above a set threshold - both between sentences and mid-sentence
• ✅ Handles the silence around "um" even if not the word itself
• ✅ Output is a complete edited video - no additional editing required
• ⚠️ Does not detect specific filler words - detects silence/pauses instead

Practical difference: If your filler word habit is "um" followed by a 2-second pause, BlitzCut removes the silence. The "um" sound itself (if spoken quickly with no pause) stays in - but in practice, most filler words come with surrounding silence that BlitzCut removes. Cleanvoice removes the actual word more surgically.

For most video creators, BlitzCut's silence-based approach is sufficient and faster. For audio podcasters who want surgical filler word removal, Cleanvoice is more precise.

Does Cleanvoice Work with Video Files?

This is where many creators get surprised. Cleanvoice's workflow is:

1. Upload your file (audio or video)
2. Cleanvoice processes the audio track
3. Download a cleaned audio file (.mp3 or .wav)

When you upload a video file to Cleanvoice, it extracts and processes the audio. The video component is discarded. You receive back an audio file, not a video file.

This means: Cleanvoice cannot replace a video editor for video creators. After using Cleanvoice, you must still:

1. Import the cleaned audio back into a video editor
2. Re-sync the audio with the original video (or manually adjust cuts)
3. Add captions separately
4. Export the final video

This combined workflow typically takes 20–30 minutes for a 5-minute video.

BlitzCut, by contrast, outputs a complete edited video with silence removed and captions added in ~2 minutes.

Caption Generation: BlitzCut Only vs Cleanvoice None

BlitzCut AI captions:

• ✅ Automatic transcription - 95%+ accuracy
• ✅ One-tap styled presets (word highlight, animation, color options)
• ✅ Burned-in captions visible without viewer action
• ✅ Completes in 30 seconds

Cleanvoice AI captions:

• ❌ No caption generation feature
• ❌ Captions must be created with a separate tool after Cleanvoice processing

For social media posting, captions are essential - 85% of social video is watched without sound. Cleanvoice's workflow leaves captions entirely to you. BlitzCut delivers them automatically in the same session.

Output Format: Audio File vs Edited Video Ready to Post

This is the most fundamental difference between the two tools.

Cleanvoice output: A cleaned audio file. You still need to:

• Import audio into a video editor
• Re-sync audio to video
• Trim video to match audio cuts
• Add captions
• Export for social media

BlitzCut output: A complete edited video file with:

• Silence removed from both audio and video
• Styled captions burned in
• Correct aspect ratio for the target platform
• Ready to post directly to TikTok, Reels, or YouTube Shorts

For video creators, the additional steps after Cleanvoice add 15–25 minutes of work. BlitzCut eliminates those steps entirely.

Pricing Comparison

Plan	Cleanvoice AI	BlitzCut AI
Free	30 minutes trial	Watermarked exports
Paid	$9/mo (10 hours audio)	$9.99/mo unlimited
Overage	$0.09/min beyond 10 hours	No overage fees
For 20 hours/mo	$18/mo (next tier)	$9.99/mo (same price)

At the entry level, they cost approximately the same. BlitzCut is unlimited at $9.99/mo - Cleanvoice charges by the hour, which adds up for high-volume creators.

Additionally, most video creators using Cleanvoice would still need a video editing app separately - adding another $10–25/mo to their tool stack. BlitzCut consolidates the entire workflow into one $9.99/mo subscription.

Frequently Asked Questions

Can Cleanvoice remove silence from video files? Cleanvoice can accept video files as input but outputs only the processed audio track - not a video file. You will need to re-sync and re-export the video in a separate editor. For video creators, BlitzCut's single-workflow approach is significantly more efficient.

Does BlitzCut remove specific filler words like "um" and "uh"? BlitzCut removes silence - the pauses that accompany most filler words. It does not target specific words by language model. In most speaking patterns, "um" and "uh" are followed by a pause, which BlitzCut removes. Cleanvoice is more surgical if you need the word itself removed even without a following pause.

Is Cleanvoice worth it for podcasters? For audio-only podcasters, yes - Cleanvoice is specialized and effective at its core function. For video podcasters or creators who clip podcast content for social media, BlitzCut is a more complete solution.

Can I use both Cleanvoice and BlitzCut together? You could, but it is unnecessary for most video workflows. Cleanvoice would add a step without solving the additional problems (captions, video output) that BlitzCut handles. For pure audio production, use Cleanvoice. For video production, use BlitzCut alone.

Does BlitzCut work without an internet connection? Yes. BlitzCut AI processes video entirely on-device - no internet connection is required for editing. Cleanvoice requires uploading to cloud servers.

What's the accuracy of BlitzCut AI captions vs Cleanvoice's transcript? BlitzCut AI achieves 95%+ caption accuracy. Cleanvoice's transcript (included with most plans) achieves approximately 90–92% accuracy. Cleanvoice's transcript is useful for show notes; BlitzCut's captions are styled and burned into the video for social media posting.

The Verdict

For audio-only podcast production: Cleanvoice AI is the right tool - it's specialized, effective, and focused exactly on cleaning podcast audio recordings.

For any video creator: BlitzCut AI is the complete solution. It removes silence from video (not just audio), adds styled captions in one tap, and outputs a finished video ready to post - all in about 2 minutes. The combined Cleanvoice + video editor workflow takes 30–60 minutes to achieve the same result.

If you record video and post to TikTok, Reels, YouTube Shorts, or LinkedIn, BlitzCut is the only tool you need.
