Sentence expander

What Expand mode does

Bullet-style notes that have to become a paragraph, a sentence that is correct but too abrupt for the reader, a draft that a teacher or editor has marked "develop this". Expand mode is for text that is too compressed, not for text that is missing content. Expand turns clipped sentences into complete ones, spells out abbreviations and shorthand, adds the connective words that show how the ideas relate ("largely because", "in contrast") and restores the subject and verb that notes leave out. It is built not to invent: no new facts, figures, causes or examples appear.

How to use the sentence expander

Three steps, and the third is where the checking happens.

Paste the passage

Type it, paste it, or upload a PDF, DOCX, TXT or Markdown file. A sentence or a few paragraphs; the example below is one short passage.

Check the settings

Expand is already selected on this page. Leave the synonyms slider at Balanced for a first run, keep Protect names & numbers on, and freeze any term that must not change.

Read what changed

Every changed word is highlighted against your original. Click one for alternatives, edit the result in place, run it again for another version, or copy and download it.

Before and after in Expand mode

A real run of the tool, unedited, so you can judge the mode on what it actually returned.

Your text21 words

Sales fell 8% in Q2. Bad weather hurt footfall in the shops. Online orders grew 12%. We expect Q3 to recover.

Expand mode41 words

Sales declined by 8 percent during the second quarter, largely because adverse weather conditions reduced the number of customers visiting the physical stores. In contrast, online orders increased by 12 percent. We anticipate that the third quarter will see a recovery.

Twenty-one words became forty-one. Both figures, the weather, the online growth and the forecast are all there and nothing new was added; the tool spelled "8%" as "8 percent" and "Q2" as "the second quarter", which is Expand doing its job on shorthand. Generated by the paraphraser on 18 September 2026 in Expand mode at Balanced strength with Protect names & numbers on, printed here unedited.

What Expand mode changes

The three kinds of edit it makes, with the words from the example above.

Clipped sentences into full ones"Sales fell 8% in Q2" becomes "Sales declined by 8 percent during the second quarter". The information is identical; the sentence is now complete prose.
ConnectivesFour separate statements become a passage: the weather is now given as the reason for the fall, and online growth is set "in contrast" to it, because that is how the notes related them.
Shorthand"Q2", "Q3" and "footfall" are spelled out for a reader who did not write the notes.

What it leaves alone

A paraphrase is judged by what it does not touch.

The facts, and only the facts8%, 12%, the weather, the recovery: the rewrite contains exactly the claims the notes contained. Expand does not add an example, a statistic or a reason that was not there.
Your position"We expect Q3 to recover" stays a forecast; it does not become a promise or a certainty.
Names and numbersProtect names & numbers is on by default. Note that Expand may spell a figure out ("8 percent") or write a quarter in words; the value never changes.

How far to move it

The synonyms slider sets the degree of change: Light, Balanced or Extensive.

Strength for ExpandBalanced roughly doubles the word count of terse notes and produces ordinary connected prose. Light only completes the sentences. Extensive (Pro) also varies the sentence structure and is the setting for notes that have to read as finished writing.
Protect names & numbersOn by default. Figures, dates, citations and organisations stay exactly as written. Switch it off only when a number itself is what you want reworded.
FreezeClick any word in the result and freeze it. A frozen term survives every later run of any mode.

Common mistakes with Expand mode

Five ways a expand rewrite goes wrong, and how the diff catches each one.

Expecting new content

Expand does not research, and it does not pad with generalities. If a paragraph is thin because it is missing an argument or evidence, no rewrite fixes that; the missing material has to come from you.

Expanding to hit a word count

A paragraph that has been inflated reads as inflated. Use Expand to turn notes into prose, then let the length be what the content needs.

Letting a forecast become a fact

Connective words carry meaning. Check that "expect", "may" and "likely" survived and that a cause the notes only implied has not become a stated one you cannot support.

Expanding a quotation

Quoted words stay as they were. Expand the sentence around the quote.

Running Expand on finished prose

It will make complete sentences longer, which is rarely an improvement. Expand is for compressed text.

Sentence expander FAQs

Is the sentence expander free?

Yes. Expand is one of the six free paraphrase modes, and you can use it without an account within the per-request word allowance shown next to the editor. Signing in raises the allowance; Pro removes the guest limits and the ads and adds the Academic, Creative and Custom modes and the Extensive synonyms level.

Will the sentence expander add information?

No, and that is the point. It completes sentences, spells out shorthand and adds the connecting words that show how your ideas relate, using only what the text already says. If the result seems to state something you did not, the highlighted diff will show where, and you should edit it.

How is Expand different from the AI Writer?

The AI Writer writes new content from a brief. Expand rewrites content you already have into fuller prose without adding to it. Notes into a paragraph is Expand; a paragraph from a topic is the AI Writer.

Can it expand a single short sentence?

Yes. A one-line answer that reads as abrupt comes back as a complete sentence or two that says the same thing with its subject, verb and connective in place. It will not add a second point.

Will the sentence expander change names, numbers or dates?

Not unless you switch Protect names & numbers off. It is on by default, so a figure, a date, a citation or an organisation stays exactly as written while the sentence is rebuilt around it. You can also click any word and freeze it so it survives every run.

Can I see what the sentence expander changed?

Yes. The result comes back with every changed word highlighted against your original, and you can switch to the original at any time to compare. Click a highlighted word for alternatives, edit the result in place, or step back to an earlier version.

One page per paraphrase mode

Each page opens the paraphraser with that mode already selected, shows a real before-and-after the tool returned, and explains what the mode changes and what it leaves alone. Standard, the default mode, is the main paraphraser page; Academic, Creative and Custom are part of Pro and live in the mode menu above.
