ElevenLabs voices are stunning until the one take you ship has a garbled syllable, a mispronounced name, a clipped peak, or a half-second of dead air where the model dropped out. Those artifacts hide inside otherwise-clean audio and you don't hear them until a listener does. UploadCheck listens to your exported MP3/WAV before you publish and flags garbled TTS, clipping, silent dropouts, and loudness that's off-spec — so a re-generate costs you a minute, not a re-upload.
broken videos published. Every ElevenLabs audio gets one final pass, so a frozen frame or dropped word never reaches your audience.
instead of re-watching a 20-minute export. UploadCheck finds the one bad moment with its exact timestamp — no more scrubbing to hunt for it.
saved off every delivery. No re-export → re-upload → "why is there a black frame at 0:14" from a client after it went live.
It doesn't replace ElevenLabs — it's the automated final QC pass on the finished export, the thing an editor can't reliably do by eye.
Same engine every way. The free scan runs 35 automated checks; a paid plan adds the AI gates (garbled speech, on-screen continuity, narration match) and lifts the hourly limit.
Use Claude Code, Codex, Cursor, or any LLM for production? Paste our one-time setup prompt and it wires a /check command. Then just say "check my ElevenLabs audio" — the AI runs UploadCheck and reads back the findings. Free needs no key.
Export your video or audio from ElevenLabs, then drop the file into the free scan. No account, no tools — a real PASS / BLOCK verdict with timestamps in seconds.
Start free →On a paid plan, upload the ElevenLabs audio straight into your UploadCheck dashboard — same engine as the free scan, with every AI gate on and no hourly throttle. Paste a link or choose a file.
See paid plans →You generate and export your audio in ElevenLabs as usual, then run the finished file through UploadCheck — from the web, the CLI, or your AI assistant. UploadCheck scans it for problems ElevenLabs can't check, returns timestamped flags and fixes, and you re-check until it passes.
Garbled or unintelligible speech, audio dropouts and dead air, clipping and distortion, off-target loudness, and format/codec issues — each with the exact timestamp.
No. UploadCheck is the last step after your ElevenLabs audio — one check before you publish. It doesn't touch your ElevenLabs project; it inspects the finished file and hands you (or your AI) a repair list.
Does UploadCheck catch ElevenLabs generation glitches? Yes — the deterministic garble gate is built to flag the slurred, warbled, or robotic syllables the model occasionally produces, dead_air and dropout catch silent gaps where a generation stalled, and clipping/loudness catch peaks and levels that are off-spec for your platform. For dubs, the omni_watch and gemini_watch oracle gates listen to the full track and surface mispronounced names or moments where the localized speech drifts from the intended line, and report back the exact timestamps so you can re-generate just that segment.
Instead of re-watching a clip to hunt for the one bad moment — or worse, finding it after you've published — UploadCheck flags it in one pass with the exact timestamp. Catching one bad audio before publish saves the re-generate/re-export, re-upload, and the reputational hit of a broken clip going live.
