EchoSubs is a desktop AI app for Mac and Windows that removes burned-in (hardcoded) subtitles with local AI inpainting. Files stay on your machine. Built for NDA work, localization queues, and course libraries — not a browser timeline editor.
A 2-minute walkthrough showing how EchoSubs removes hardcoded subtitles locally with AI inpainting. Video stays on your machine with zero cloud upload.
EchoSubs is engineered specifically for privacy-first, high-throughput video processing workflows.
Cleaning client-confidential or NDA-protected footage before re-captioning and translating into new languages, where third-party cloud uploads are legally prohibited.
Operating under strict GDPR, HIPAA, or corporate data-residency compliance rules that automatically rule out cloud SaaS video tools.
Batch-cleaning extensive archives of legacy lesson videos that already have burned-in captions, without waiting on slow browser upload queues.
Understanding the technical difference explains why burned-in text cannot simply be "switched off".
Soft subtitles sit in an independent metadata track separate from video frames. You can toggle them on or off in player settings, swap subtitle languages, or remove the file entirely without touching video pixels.
Hardcoded subtitles are permanently baked into the video pixels themselves. They travel with every export and cannot be toggled off. Re-editing the original project is expensive — and often impossible when you only have the delivered master.
If the text is burned in, cloud "removers" require uploading that delivered master to external third-party servers. For agency and client work, that is often a contract and legal problem before it is even a quality problem.
Agencies and regulated teams encounter the exact same recurring hurdle:
Client footage cannot leave the building (or the approved internal network).
A free browser-based tool demands an upload to a remote cloud server.
Legal says no — so the production team is forced to rebuild edits by hand, or ship with the wrong language burned in.
EchoSubs is a native desktop application, not a cloud SaaS. There is no cloud upload path — not even as an opt-in. Subtitle detection and AI inpainting run entirely on your local CPU/GPU. Internet is only used to validate the software licence.
This local architecture is why EchoSubs is trusted for NDA-protected, client-confidential, and GDPR-sensitive workflows.
A focused inpainting engine designed for precision without damaging surrounding frames.
Auto-suggests subtitle coordinates with fine-grained bounding box adjustment tools for multi-line or non-standard positioning.
Reconstructs the underlying background textures frame-by-frame using spatial-temporal AI models instead of a simple static blur.
Saves a pristine clean master file next to the original, immediately ready for new translated captions or voiceover dubbing.
Clear separation between local compute and network licensing.
After activation, you can disconnect the network and keep processing. Source files never leave your filesystem.
EchoSubs does not log filenames, durations, frame contents, audio, or transcripts for content telemetry (anonymous crash/version metrics can be disabled).
Drop a single video file or an entire folder of files. Queue client deliverables or online lesson libraries overnight, review in the morning, and only spend editing time on outliers that need an extra manual pass.
That matches how localization teams actually work: volume first, exception handling second — not one clip open at a time in a slow browser editor.
We queue our batches overnight, do a quick spot-check review in the morning, and fix only the outlier frames that need an extra pass. It transformed our turnaround time for client projects.
Choose the right tool for your specific project requirements.
| Feature | EchoSubs | Veed / CapCut-Style Browser Tools |
|---|---|---|
| Privacy | Local desktop; no upload path | Upload to cloud / online workspace |
| Hard-sub Removal | AI inpainting (no-blur reconstruction) | Convenient for light cleanup; simple blur/mask |
| Batch / Folder | Built for large folder queues | Usually per-project / per-clip |
| Best When | Confidential footage + volume + quality | One or two non-sensitive clips; want zero install |
EchoSubs runs on any supported Mac or Windows PC; processing speed is GPU-bound.
On Apple M1/M2/M3 or NVIDIA RTX 3060-class hardware (~2.3 min average per 1080p).
CPU-only execution is fully supported when no dedicated GPU is present, running 3–4× slower.

• Subtitle generation can be tried without a paid licence; exports are watermarked.
• Hard-subtitle removal (and PPT/PDF → video) require a paid licence to run end-to-end.
• Hard Sub Removal is included on paid plans listed on the site (e.g. Standard lifetime and higher tiers on our pricing page).
Answers to common privacy, security, and technical questions.
Yes. EchoSubs processes locally on your computer. There is no upload path for source footage.
After license activation, yes. All inpainting and detection models run locally on your machine; the network is used solely for license verification, never for transmitting video data.
That is the exact intended use case: NDA, client-confidential, and regulated workflows where cloud SaaS is not permitted. Confirm with your security team; enterprise customers can request a security questionnaire by contacting us.
Those tools focus on browser convenience and lightweight editing. EchoSubs is purpose-built for offline privacy, folder batching, and high-fidelity AI inpainting for volume work — and is deliberately a dedicated removal engine rather than an NLE editor.
EchoSubs performs true AI inpainting to reconstruct the background textures across frames, rather than applying a simple static blur or solid color mask.
Yes — folder and batch queue processing is a core feature. The typical workflow is to queue the batch, let it run, and review the outputs in the morning.
You get a clean video file next to the original, ready for re-captioning or re-voicing in another language. (EchoSubs also offers caption generation as a separate module on paid/trial terms).
