InstantPrompter vs Speakflow, what we checked
Speakflow runs a comparison hub and a reading-time cluster; this is a browser teleprompter. What we verified on 27 August 2026, and what we could not.
Start with what this page cannot tell you
We make InstantPrompter, so one of the two products here is ours.
Our check of Speakflow was also shallower than our check of some other tools. We read their public pages and their sitemaps on 27 August 2026. We did not sign up, did not open the editor, and did not put a script through it. So this page can tell you what Speakflow publishes and how their site is laid out. It cannot tell you what their product feels like to use, and we are not going to imply otherwise by filling in a feature table from the outside.
Speakflow looks like a script product with a teleprompter in it. This is a teleprompter you can read from the moment the page loads. Those are different things, and which one is wrong for you depends on what you were about to do.
What we could verify about Speakflow
We read every row below off their live site on 27 August 2026.
| What we looked at | What we found | Source |
|---|---|---|
| Dedicated tool page | A /teleprompter page separate from the homepage | speakflow.com/teleprompter |
| Comparison pages | A /compare hub plus four versus pages: BigVu, Teleprompter.com, Teleprompter Pro, Vodium | speakflow.com/compare |
| Reading-time pages | Eight exact-match URLs of the form "how many words in N minutes", for 2, 5, 10, 15, 20, 30, 45 and 60 | speakflow.com sitemaps |
| Script tooling | A /script-checker page | speakflow.com sitemaps |
| Sitemap shape | Three sitemap index files rather than one flat list | speakflow.com sitemaps |
A site that needs three sitemap index files is not a single page with a text box on it. That is the clearest thing the structural check tells you, and it is worth more than a guess about their settings panel.
Their comparison hub covers four products and does not include CuePrompter, which is the free web teleprompter most people have already heard of. We are not going to guess why, but it is one reason our own CuePrompter comparison exists: nobody outside the market had written one.
What we did not check
- Price. We do not know what Speakflow costs, whether there is a free tier, or what a free tier includes. Their pricing is on their site and we did not read it into this page. Anything we wrote here would be a number we had not verified, and a wrong price is the fastest way to lose a reader.
- Signup. We do not know what you have to give them before the tool moves.
- Features. Voice tracking, imports, remotes, recording: unchecked. Their pages are the place to find out.
- Speed. We have no load or responsiveness measurements for either tool.
That list is longer than we would like. It is also the honest state of what we looked at, and a comparison page that hides its gaps is worse than one that prints them.
What this one is
InstantPrompter is a teleprompter in a browser tab, and that is the whole of it. The script scrolls past a fixed reading line near eye height so your eyes stay level with the lens, and the controls sit in a dock along the bottom of the stage so changing the speed does not mean looking away from the line you are reading.
There is no install and no account. When the page loads, a short sample script is already in the box and Play already has focus, so pressing Space starts it. To use your own script, paste it: Cmd+V, or Ctrl+V on Windows, replaces what is in the box without your having to click into it first, and Space still starts it from there. Nothing scrolls until you ask it to, which is deliberate.
Your script lives in your browser, on the machine you typed it on. It is not uploaded, not synced between your devices, and not attached to an account, because there is no account. The cost of that is real: a script written on your laptop will not be waiting on your phone, and clearing your browsing data clears your scripts with it. If a script matters, keep the original somewhere you control.
What this tool does, including what it does not
This table is about InstantPrompter only. We did not test Speakflow feature by feature, so there is no Speakflow column. Anything we put in one would be read off their marketing pages, and a column built that way is wrong at exactly the moment somebody relies on it.
| Capability | Here |
|---|---|
| Signup | Not required. There is no account to make |
| Where the script is kept | Your browser, on the machine you typed it on |
| Speed unit | Words per minute |
| Duration estimate | Yes, from the same words per minute the scroll uses |
| Mirror for a beam splitter | Yes |
| Voice follow | Yes, off until you switch it on |
| Fullscreen | Yes, and it returns you to the same position |
| Countdown | Three seconds, and it can be switched off |
| Several scripts side by side | Yes |
| Reduced motion | Followed by default, and overridable |
| Record video | No |
| Phone as a remote | No |
| PDF or Word import | No |
| Cloud sync or accounts | No |
| Team accounts or sharing | No |
The bottom five rows are the ones worth reading twice. A script product tends to have some of them. This does not, and none of them are on the way.
Where the two overlap
Both tools will tell you how long a script takes to read. It is the same arithmetic in both cases, and the difference is how much of a site each of us built around it.
Speakflow built eight pages, one for each duration people search for. We built one, at /tools/script-timer, and decided against the other seven. If what you want is a page that answers "how many words in five minutes" and nothing else, they have that page and we deliberately do not.
What our one page does have is the same words-per-minute number the prompter scrolls at. On the stage, the estimate and the scroll read from one setting, so there is a single number rather than two that nearly agree. That matters more than it sounds like it should. Speed here is words per minute rather than pixels per second, and pixels per second is a property of a screen: change the text size or the window width and the same setting reads at a different pace. Words per minute is a property of you. Set it to the rate you talk at and it stays that rate on a laptop, on a tablet propped beside the lens, and in fullscreen.
Most people land somewhere between 120 and 160 words per minute on camera. Start in the middle, read a paragraph aloud, adjust once, and leave it.
Where Speakflow is the better answer
- You want a workspace for the script itself. Their site is built around scripts as documents, with a script checker and a tool page of its own. This one gives you a box, several scripts side by side, and nothing else.
- You are shopping against paid teleprompter software. They maintain comparisons with BigVu, Teleprompter.com, Teleprompter Pro and Vodium, which tells you who they expect to be evaluated next to.
- You need anything in the bottom five rows of our table. Recording, a phone remote, file import, sync, team access: we do not do any of it, and we did not check whether they do. Their pages will tell you.
- You want a page per duration. They have eight; we have one.
Where this one is the better answer
- You need to be reading in the next thirty seconds. Load, press Space, read. No install, no account, no upload step.
- The script cannot leave the machine. An unreleased announcement, a legal statement, a draft nobody has cleared: those can go in the box without being sent anywhere. That is a property of where the script is stored, not a promise about a policy.
- You want the speed number to survive a change of screen. Words per minute does. Pixels per second does not.
- You read off a beam splitter. Mirror mode flips the picture, and the setup details are on its own page.
- You want voice follow with the audio path stated up front. It stays off until you turn it on. Browsers that can transcribe on the device do it there. Browsers that cannot, which today means Safari and iOS, hand the audio to the browser vendor under that vendor's terms. We are not in that path either way: we do not receive, store, or forward your audio. The voice follow page names which browsers currently sit on each side.
How to decide in ten minutes
Take the actual script you were about to read. Not a sample, not a paragraph of filler, the real one.
- Paste it into both and set both to the speed you talk at.
- Read the first thirty seconds out loud at your camera.
- Count what you had to do before the text moved.
- Ask what happens to the script when you close the tab, and see whether each tool answers that where you can find it.
- Pick the one that got out of the way.
If the answer is Speakflow, that is a real answer and this page will have done its job.
Questions
Is this page independent? No. We make one of the two tools. The date and the source links exist so you can check the parts that are checkable, and the section on what we did not check exists because it is a longer list than usual.
What does Speakflow cost? We did not verify it, so we are not printing a number. Their site has it.
Is this tool free? Yes, and there is nothing to upgrade to.
Does my script get uploaded here? No. Your browser keeps it on your own machine.
Can I import a Word file or a PDF? No. Paste the text in.
Will these facts still be true? The Speakflow rows are dated 27 August 2026. When we re-check them, the date changes with them.
The tool is on the home page, loaded with a sample script so you can judge the scroll before pasting anything. The other comparisons are CuePrompter and Teleprompter.com, and the comparison hub covers the rest of the field.
