What has actually been measured
On 22 August 2026, we submitted one 24.4-second synthetic recording to a local Journo backend connected to its real transcription and journal-processing providers. The same fixed file, script and evaluation format are prepared for six products.
| Product | Current status | Public evidence |
|---|---|---|
| Journo | Measured once | Audio, result JSON and response JSON published |
| AudioNotes | Not measured | None |
| Voicenotes | Not measured | None |
| Cleft | Not measured | None |
| ChatGPT | Not measured | None |
| Untold | Not measured | None |
An empty cell would invite an assumption. “Not measured” means exactly that: we have not run a controlled test that meets the publication method below.
The current Journo baseline
| Measure | Result |
|---|---|
| Recording length | 24.4 seconds |
| Time to readable server result | 9.655 seconds |
| Reference words | 82 |
| Raw-transcript substitutions | 0 |
| Raw-transcript deletions | 0 |
| Raw-transcript insertions | 0 |
| Journal-output word changes | 0 |
| Journal-output formatting changes | Punctuation and paragraph breaks |
The run measured the server path. It did not measure phone upload time, offline capture, on-device audio retention, recovery after a force-quit, noisy speech or accent coverage. Those observations remain not_tested in the result rather than being inferred from Journo’s source code.
Download the evidence
- Play or download the fixed synthetic recording.
- Inspect the dated benchmark JSON.
- Inspect the hash-verified Journo response.
- Run the seven product-neutral failure tests.
The audio SHA-256 is a077ab55a51ca795cdf9e67087e3ceaa75a84b513ccfa7c6d7c2535957e6b443. The response-evidence SHA-256 is 2df9df2c6433d719203fab18e4d620fb081b243814c9cd6ac1b383f520193011. Those hashes let another reviewer verify that the files used for a rerun have not silently changed.
How the measurement works
- Use the identical audio file and record its SHA-256.
- Record product version, plan, device, network and UTC test time.
- Start timing immediately before submission and stop at the first complete readable result.
- Preserve the raw transcript and journal output exactly as returned.
- Compare lowercase word tokens with the fixed script to count substitutions, deletions and insertions.
- Publish the response evidence and its cryptographic hash.
- Mark anything not directly observed as not tested.
This first baseline used a synthetic voice and an ordinary, non-sensitive reflection so the artifact can be public. Real journal content must never enter the corpus.
What would justify a broader claim
This page will not name a speed, accuracy or reliability winner until all six products have been tested under the same method. A stronger publication requires, at minimum:
- the fixed synthetic sample through every product;
- three consenting human speakers with different speaking patterns;
- identical timing and evidence capture;
- product versions and test dates;
- a rerun when a material product change makes a result stale.
Even then, the result would describe this corpus and protocol—not every speaker, language, room or device.
Reproduce or challenge it
Download the corpus and result. If you find a counting error, a stale product fact or a method that creates an unfair comparison, send the exact issue through Journo Support. Corrections and material method changes follow the public research methodology.
The useful outcome is not a flattering score for Journo. It is a test another person can inspect and a clear boundary around what the evidence does not show.

We use first-party product documentation and original research wherever possible. Features and prices can change.
