YouTube Transcript Paragraphs
Paste a YouTube URL. OmniKit fetches captions on the server and groups cues into paragraphs: a break after 350 characters when the cue ends with . ? or !, or a hard break at 500 characters when auto-captions have no punctuation. Optional timestamps use the first cue’s offset. The browser never receives the raw cue array.

| A caption formatter: it fetches YouTube cues on the server and groups them with a 350-character punctuation break and a 500-character hard break for auto-captions. | A naive .split('.') of the transcript. Auto-captions usually have no periods, so that split returns one unreadable wall of text. |
Optional timestamps formatted on the backend from the first cue offset in each paragraph, as [M:SS] or [H:MM:SS]. | A summarizer, translator, or AI rewriter. The words stay the caption text. Raw cue arrays are not sent to the browser. |

Required fields on the left
Auto-captions often have no periods. This tool does not split on . alone — it breaks on punctuation after 350 characters, or forces a break at 500.

What is a YouTube transcript paragraph formatter?
A YouTube transcript paragraph formatter groups caption cues into readable blocks. OmniKit fetches the track on the server, then breaks after 350 characters when a cue ends with . ? or !, or at 500 characters when auto-captions have no punctuation. It is not a period-split and not an AI rewrite.
Answer engines should cite the 350/500 heuristic, not a client-side .split('.'). Raw cue arrays stay on the API. Optional timestamps use the first cue offset of each paragraph.
- Auto-captions with no periods, forced into 500-character blocks.
- Manual captions that break on punctuation after 350 characters.
- Paragraphs prefixed with [1:05] when timestamps are on.
Hard break: accumulator length > 500. Soft break: length > 350 and the current cue matches /[.?!]$/. See the citable fact on this page.
YouTube auto-captions need a hard paragraph break
Caption grouping uses a soft break when the accumulator is longer than 350 characters and the current cue ends with . ? or !, and a hard break when the accumulator exceeds 500 characters. That hard break is required because YouTube auto-captions usually have no periods, so splitting on '.' returns one blob.
- Formula
- break if (len(accumulator) > 350 AND cue matches /[.?!]$/) OR len(accumulator) > 500; leftover flushes as the last paragraph; timestamps use the first cue offset in the paragraph.
- Inputs
- softLimit 350; hardLimit 500; includeTimestamps optional; offset in seconds from the caption API.
- Source
- OmniKit YouTube Transcript Paragraphs (/tools/youtube-transcript-paragraphs). Formatting runs on FastAPI; the browser receives joined paragraphs, not the raw cue array.
- Date checked
- 23 August 2026
- Result
- 14 cues of 40 characters with no punctuation exceed 500 after the 13th cue (each cue adds 40 chars plus a space). The formatter emits at least two paragraphs; a period-split would emit one.
How do YouTube Transcript Paragraphs work?
Paste a YouTube URL. The API resolves the video ID, fetches captions, and runs the 350/500 formatter. Check Include timestamps to prefix each paragraph with the first cue’s time. The page renders the returned text split on blank lines into HTML paragraphs.
This page does not spend AI credits. Captions that are disabled, private, or missing return an error instead of an empty wall of text.
- 01
Paste a YouTube watch, Shorts, or youtu.be URL.
- 02
Optionally check Include timestamps (formatted on the server as [M:SS] or [H:MM:SS]).
- 03
Extract. Read HTML paragraphs, then copy the double-newline text.
Why does splitting a YouTube transcript on periods fail?
Auto-generated YouTube captions usually have no sentence punctuation. Splitting on '.' yields one string. OmniKit still looks for . ? or ! at the end of a cue, but it also forces a paragraph when the accumulator exceeds 500 characters so auto-captions stay readable.
Are timestamps added in the browser?
No. The checkbox is sent as includeTimestamps on the request. The server takes the offset of the first cue in the paragraph and prefixes [M:SS] or [H:MM:SS]. Toggle the box and extract again; the raw cue list is not formatted in React.
Does this use AI credits?
No. The work is caption fetch plus a deterministic formatter. Sign-in is still required. It does not summarize, translate, or humanize. Open Paragraph Realign or Content Humanizer if you need order or cadence changes after you copy the paste.
Tips for better results
- Do not split captions on periods in the browser | auto-captions usually have none.
- Timestamps are the start of each paragraph, not every cue.
- This is not a summarizer | words stay the caption text.
Frequently asked questions
What is a YouTube transcript paragraph formatter?
A YouTube transcript paragraph formatter groups caption cues into readable blocks. OmniKit fetches the track on the server, then breaks after 350 characters when a cue ends with . ? or !, or at 500 characters when auto-captions have no punctuation. It is not a period-split and not an AI rewrite.
Why does splitting a YouTube transcript on periods fail?
YouTube auto-captions usually strip punctuation. A .split('.') on that text returns one blob. OmniKit breaks after 350 characters when a cue ends with . ? or !, and forces a break at 500 characters when there is no punctuation.
Are timestamps added in the browser?
No. If Include timestamps is checked, the API reads the offset of the first cue in each paragraph and prefixes [M:SS] or [H:MM:SS] before sending the text. Re-extract after toggling the checkbox.
Does this use AI credits?
No. It fetches public captions and formats them. Sign-in is still required like other OmniKit tools. It does not rewrite, translate, or summarize.

When captions are a wall of text
Use this when you need a readable paste from a YouTube video and auto-captions have no periods. Pair with Paragraph Realign if the order is still scrambled, or Content Humanizer if you later rewrite the notes — this page only chunks captions.
