The caption starts with the buyer question, followed by “In this demonstration,” the product, and your fact. Optional text can add what the clip does not show, a CTA, and disclosure wording. If you provide both a follow-up question and your answer, the tool creates a separate editable reply; it rejects an incomplete pair and never invents the answer.
Build context around the demonstration
The required inputs are a product, a buyer question, and a fact you can verify. The caption begins with the question and continues with “In this demonstration: [product]. [fact].” An optional limitation is appended as “What this clip does not show: [your text],” followed by optional CTA and disclosure text. The tool uses the wording you provide and leaves the result editable.
This page supports two connected jobs: adding context and a stated evidence boundary to a product Reel, then preparing a reply to a follow-up question. The TikTok caption tool is the shorter product-or-user-supplied-phrase post caption; it has no clip-limitation field or separate reply. K14's difference is its caption-plus-reply preparation, not a claim about platform distribution or comment visibility. It does not generate generic hooks, fetch comments, or make hashtags.
Prepare a separate reply using your answer
Reply preparation is optional. Enter both a follow-up question and an answer you can support, and the tool places those two supplied lines in a separate editable reply field with its own copy button. If you fill only one of the pair, generation stops with an error asking for both fields or neither.
The tool does not read comments, infer what a buyer means, or draft an answer from the product fact. Use a real question and write a response that matches the evidence you have; the reply remains your responsibility to review.
Worked example with hypothetical inputs
Every value below is invented to demonstrate the fields and output; it is not a product test, real buyer comment, or verified claim. A seller would need to verify the stated measurement and the scope of any test before using similar wording.
| Input or output | Illustrative text | Evidence boundary |
|---|---|---|
| Product | Clip-on reading lamp | Hypothetical item name. |
| Buyer question | How wide does its clamp open? | The clip should show the same model named in the caption. |
| Fact supplied by seller | The clamp opening measures 18 mm. | Hypothetical measurement; verify it on the exact product or a reliable record. |
| What the clip does not show | Grip on every surface or long-term wear has not been tested. | A limitation supplied by the seller, not inferred by the tool. |
| Optional CTA | Compare the opening with the edge you plan to use. | Keep only if the measurement and next step are accurate. |
| Follow-up question | Will it grip every desk edge? | Hypothetical comment used to demonstrate the separate reply. |
| Answer supplied by seller | I only checked it on the sample edge shown; I have not tested every desk surface. | The answer is user-written and must reflect the seller's actual test. |
| Separate generated reply | Will it grip every desk edge? I only checked it on the sample edge shown; I have not tested every desk surface. | The tool joins the two supplied fields; it does not verify or create the answer. |
Review the caption and disclosure
The tool cannot inspect the Reel or verify the product fact, the limitation, the CTA, or the supplied reply. Compare every line with the exact item, footage, offer, and evidence; remove claims the clip does not support.
The disclosure field appends plain text only. It does not determine whether a disclosure applies, choose an in-app control, or validate legal sufficiency. The FTC source below is U.S. guidance about endorsements and material connections; check current official platform controls and applicable rules for your actual post.
Required inputs and tool limits
Product, question, and fact are required. Clip limitation, CTA, disclosure text, and the reply pair are optional. Leave both reply fields empty if you do not have a specific question and a supportable answer; one without the other is an input error.
The tool runs in the browser and produces one editable caption plus, when requested, one separately editable reply. It does not connect to Instagram, retrieve comments or search data, inspect media, generate hashtags, validate disclosures, or predict views, reach, or sales.

What this page can’t establish
- The caption and reply use text you supply; the tool does not inspect the Reel, fetch comments, verify a fact, or generate an answer.
- The optional limitation, CTA, and disclosure are appended as supplied. The tool does not select or validate a platform control or legal disclosure.
- A separate reply is created only when both the follow-up question and answer are supplied; the tool does not establish whether the answer is accurate.
- The output is one editable caption and an optional separate reply, not a performance prediction, reach promise, hashtag set, or sales claim.
- Inputs are processed locally in the browser and are not uploaded or saved.
