Filler Words: What They Cost You in Seconds, Not in Style
Filler is usually treated as a style problem. On a video with a fixed runtime it is an arithmetic problem, and the number worth reading is seconds rather than words.
Filler words are the parts of a sentence you can delete without changing what it claims. On a video with a fixed runtime that is not a style question — it is arithmetic. A minute of script holds about 150 spoken words at a normal talking pace, and every word of hedging is a word the ending does not get.
The three kinds, and only two are worth cutting automatically
They behave completely differently, which is why a single "filler word list" produces bad edits.
Carries nothing. "Um", "basically", "to be honest", "at the end of the day", "in this video". Removing these changes nothing about what the sentence claims. Cut them without reading the sentence.
Says the same thing longer. "In order to" is "to". "Due to the fact that" is "because". "At this point in time" is "now". These are safe swaps because the shorter form means exactly the same thing, which is the test.
Depends entirely on the sentence. "About", "almost", "usually", "I think". These are hedges when they hedge nothing and load-bearing when they qualify a number. "About thirty minutes" and "about right" are the same word doing opposite jobs, and nothing that cannot read the sentence should be deleting either.
It cuts the first two, lists the third, and prices the whole trim in seconds at the pace you picked. It also leaves anything inside quotation marks alone, because filler in a quote is how the person talked and tidying it is putting words in their mouth.
Filler words cost seconds, and seconds are the budget
Runtime is where this stops being a taste argument. Speaking pace decides the exchange rate.

A hundred is not a large number in a first draft. On a two-minute script it is very often the difference between the ending fitting and the ending being rushed, and the trim buys it back without cutting a single idea.
The most expensive filler is at the start, because that is where the viewer is deciding.
"So, hey guys, welcome back to the channel, in today's video I'm going to be showing you" is eighteen words and roughly seven seconds before the video begins. On short-form, seven seconds is most of the window in which anyone decides to stay.
The fix is not to say it faster. It is to start at the sentence after it — which is almost always a sentence that already exists in the draft. What that first line should be doing instead is in video hook ideas.
What not to cut
Two categories get removed by over-eager editing and should not be.
Anything qualifying a claim. Deleting "about" from "about thirty percent" turns an estimate into a measurement. That is not tightening, it is a different sentence, and it is the one edit here that can make a post wrong.
Your actual voice, in a caption. A script and a caption are not the same object. In a personal caption "I really think" is often how you talk, and stripping every intensifier produces copy that reads as though it was written by a linter. Cut hard on scripts and gently on captions.
Passive voice is a separate problem
"Mistakes were made" is not filler. It is the same length as "I made mistakes" and it hides who did the thing, which is a clarity problem rather than a runtime one.
It also cannot be fixed mechanically, because turning a passive sentence around requires knowing the subject and the sentence frequently does not name one. The US government's own plain-language guidance makes the same point about why active voice is clearer, and about the cases where the passive is the right call (plainlanguage.gov). Anything that offers to rewrite the passive voice for you is guessing. Flagging it and letting you decide is the honest version, and it is what the tool above does.
Related, and worth running on the same draft: readability score covers sentence length and the grade level a passage reads at, which is the other half of why a script sounds heavy.
What are filler words?
Words you can delete without changing what the sentence claims - "um", "basically", "to be honest", "in order to". They are distinct from hedges, which look similar and often carry meaning.
How do I stop saying um on camera?
Cut them from the script first, so you are not reading them, then pause instead. A silent pause reads as thinking; "um" reads as searching, and the difference is entirely in the edit.
Do filler words hurt reach?
No platform penalises them. What they cost is runtime and attention, which is a bigger problem on a short video than any ranking factor.
Should I remove every "just" and "really"?
In a script, yes. In a personal caption, no - stripping every intensifier out of the way you actually talk produces copy that sounds like it was written for a checker.
Paste a draft into the filler word remover and read the seconds saved before you read the word count.
Between 105 and 180 words, and the range is not vagueness - it is the difference between a Reels voiceover and a live presentation. Pick the pace and the number is exact.
Most of what gets called clickbait is taste. A narrow slice of it is covered by published policy, and confusing the two is why the advice on this subject is so bad.
