01 — Filler Word Detection

Find every um. Remove any phrase.
Miss nothing.

Competitors rely on transcript-only detection that misses 448–607 filler words per hour. UMCHECK combines waveform precision with AI transcription to catch nearly all of them — then lets you add your own.

02 — Bad Take Detection

Kill bad takes. Keep the best one.
You control how far to look.

Two modes — false start detection for unscripted video, retake detection for scripted. Adjustable lookahead from 5 to 50 lines. No other tool gives you this control.

R
Retake Detection

For scripted video with a teleprompter. UMCHECK identifies when you repeated the same line and automatically keeps the last take — the one you nailed.

✓ Look-ahead Lines: 5, 10, 20, 30, 40, or 50 — you control how aggressive detection is
✓ Uses Jaccard similarity + edit distance to compare phrases
✓ 98% precision — it almost never cuts good content
F
False Start Detection

For unscripted video — conversations, interviews, commentary. Catches stutters, aborted sentences, and incomplete thoughts that make speakers sound hesitant.

✓ Pair with filler word detection for maximum cleanup on talking-head video
✓ Segments speech by pauses (0.8s+ gaps) and filters short fragments
✓ Detected content highlighted in red — review everything before applying

03 — Captions & SRT Export

Captions that actually sync
after you edit.

Every other tool requires you to re-sync captions after making cuts. UMCHECK generates SRT files from the same transcript used for editing — so every caption matches your final timeline. No drift. No re-syncing. Ever.

SRT
Frame-Accurate SRT Export

Export an SRT file that reflects every cut you made, every filler you removed, and every speed change from Turbo Mode. Drop it into Premiere, Resolve, Final Cut, or CapCut.

✓ Survives Turbo Mode speed changes — timestamps auto-adjust
✓ One workflow: remove fillers + bad takes + get captions in a single pass
✓ Already capitalized and punctuated — skip the cleanup step

Max Characters Per Line — 30 / 15 / 7

One setting, three completely different caption styles. Each word lands exactly where it should because UMCHECK already cleaned and synced everything.

Full phrases on screen YouTube, longform, accessibility
15
Short 2–3 word groups Clean talking-head captions
7
Every word = its own segment TikTok / Reels animated word-by-word captions
✓ At 7 chars, each word becomes its own text layer in Premiere, Final Cut, DaVinci, or CapCut — style and animate individually
A
Auto-Replace Brand Names

Set up a master correction list in Settings. Every transcript automatically fixes misspelled brand names, product names, and custom terms before you ever see them.

✓ Example: "Time Bolt" → "TimeBolt", "Uncheck" → "UMCHECK"
✓ Options for Ignore Case and Ignore Punctuation
✓ Runs automatically on every future transcription — set it once and done
GPT
SRT → GPT → YouTube

Your SRT is more than captions — it's a timestamped content engine. Paste it into ChatGPT or Claude and the output is publish-ready because the transcript is already cleaned and corrected.

✓ Generate title, description, and chapter markers from your SRT
✓ Upload to YouTube with time-accurate captions for accessibility and discovery
✓ Generate tags, blog posts, and social clips — all from one cleaned SRT

↻ How does UMCHECK detect filler words?
+

Waveform analysis determines where to cut. AI transcription identifies the target. Each layer does what it's best at — that's why detection approaches near 100%.

✍ Can I remove custom words/phrases?
+

Yes. Type any word or phrase, comma-separated, and UMCHECK finds every occurrence. No other editor supports this.

⚙ What's retake vs false start detection?
+

Retake detection is for scripted video — keeps the last take. False start detection is for unscripted — catches stutters and aborted sentences. You control aggression with the look-ahead setting.

▢ How does SRT export work after edits?
+

The SRT is generated from the same transcript used for editing. Every cut, speed change, and removal is already reflected. No re-syncing needed. Learn more.
