EchoSubs is best for small teams and creators who need to turn existing videos into clean, re-captionable, or localised versions without uploading footage. Typical workflows: localisation teams removing burned-in subtitles before adding new-language captions; agencies and in-house teams processing NDA-protected client video; course creators batch-cleaning dozens of lessons; and educators converting PPT/PDF slide decks into narrated MP4 lessons. The expected result is a subtitle-free or narrated video saved next to the original, processed entirely on your own Mac or Windows PC. It is not the right fit for one-off clips a free web tool can handle, real-time cloud API workflows, or live transcription.

Who should use EchoSubs? Best for small teams and creators that need to turn existing videos into clean, localised, or narrated versions without uploading footage to a cloud service.
Use case fit: best for
- Localisation teams that need to remove burned-in subtitles and re-caption videos in 60+ languages without re-shooting or re-editing
- Agencies and in-house teams processing NDA-protected or client-confidential video that cannot be uploaded to cloud SaaS
- Creators and course publishers batch-cleaning dozens to hundreds of videos in one local queue
- Educators converting PPT/PDF slide decks into narrated MP4 lessons
- Organisations under GDPR or data-residency constraints that rule out cloud processing
Not ideal for
- One-off subtitle removal where a free online tool is sufficient
- Workflows that need a real-time cloud API — EchoSubs is a desktop app, not a SaaS endpoint
- Live transcription — EchoSubs is built for post-production
Security & Privacy
Your videos never leave your machine.
EchoSubs is a desktop application — not a SaaS. Every operation, from subtitle detection to AI inpainting to PPT-to-video rendering, executes on your local CPU/GPU. There is no cloud upload path at all, even as an opt-in. That makes EchoSubs the only realistic option for NDA-protected, client-confidential, or regulated video work.
100% offline processing
Every frame of inpainting, every audio transcription, every TTS render runs on your CPU/GPU. Internet is only used to validate your licence.
Zero cloud upload
Source files never leave your filesystem. There is no S3 bucket, no temp-upload endpoint, no opt-in cloud mode — by design.
No telemetry on content
EchoSubs does not log filenames, durations, frame contents, audio tracks, or transcripts. Anonymous app metrics (crash, version) can be disabled.
GDPR-friendly by architecture
Because videos and subtitles never traverse our servers, EchoSubs has no controller/processor role over your content. Self-contained workflow, no DPA needed.
Technical details: Licence activation uses RSA-2048; the macOS build is notarised and runs under Hardened Runtime; the Windows build is code-signed. Source code for the local processing pipeline can be reviewed under NDA for enterprise customers — contact us for a security questionnaire.
Alternatives & Comparison

Pick EchoSubs if…
You handle NDA-protected, client-confidential, or regulated video, run batches of 10+ files at a time, or need PPT/PDF → narrated MP4 in the same tool.
Pick Veed.io or CapCut if…
You need to clean up one or two short videos a year, the content isn't sensitive, and you'd rather not install desktop software. Here EchoSubs loses on convenience — it needs a ~5-minute install and a licence, while Veed.io and CapCut run free in a browser and add a timeline editor, transitions, and social templates EchoSubs deliberately doesn't.
Pick GiliSoft if…
You're on Windows-only and already own a GiliSoft licence — quality is decent but it re-encodes every video, costing more time and quality than EchoSubs' lossless pipeline.
Where EchoSubs loses — honestly
EchoSubs is a subtitle-removal, inpainting, and narration engine, not a full video editor. For a single 30-second clip you'll never touch again, installing a desktop app and buying a licence is overkill — Veed.io or CapCut clean it in the browser for free. It has no timeline editor, transitions, or ready-made social templates like CapCut, and no browser access from a Chromebook or phone like Veed.io. It is Windows and macOS only, so Linux users are unsupported. GiliSoft matches its one-time pricing on Windows, but re-encodes every export, which costs more time and quality than EchoSubs' lossless passthrough. Choose EchoSubs when privacy, batch volume, and output quality matter more than in-browser convenience.
Integrations & Compatibility

Onboarding & Setup
Onboarding: get your first cleaned video in under 5 minutes.
Setup takes about 5 minutes; it requires a macOS 12+ or Windows 10+ computer and a video file — no account, no cloud upload, no waiting in a queue. Your first result is a subtitle-free copy of your video saved next to the original. Here's the entire onboarding flow:
- 1
Download EchoSubs
macOS .dmg or Windows installer. No account required for the trial.
60 sec

Frequently asked
The questions buyers ask before they commit.
Use-case fit, security, price, migration, integrations, onboarding time, trial limits, offline capability, hardware. Direct answers — no jargon, no upsell.
EchoSubs runs 100% offline on your local machine — videos are never uploaded to any server, including ours. There is no cloud processing mode, even as an opt-in. The app uses the internet only to validate your licence; subtitle detection, AI inpainting, transcription, and TTS all execute on your CPU/GPU. This makes EchoSubs safe for NDA-protected, client-confidential, and regulated workflows where cloud SaaS is not an option.
EchoSubs has three buying options: Pro at $5.99/month (monthly subscription), Biz at $79/month (team subscription), and a one-time Lifetime licence at $69 (no subscription, includes lifetime updates). A free trial is available with watermarked output for subtitle generation; subtitle removal and PPT/PDF-to-video require a paid licence.
There is no project file to migrate — EchoSubs works directly on your source video files. Drop your original MP4/MKV/MOV/AVI/WebM/FLV into the app and it processes them with the same AI workflow regardless of which tool you previously used. SRT or VTT caption files you already have can be loaded as a starting point for translation or as a reference for inpainting masks.
EchoSubs works with MP4, MKV, MOV, AVI, WebM, and FLV video, SRT and VTT subtitle files, and PPT/PDF presentations, on macOS 12+ and Windows 10+ with Apple Silicon or NVIDIA GPU acceleration (CPU fallback supported). It does not currently support a REST API, a command-line interface, Zapier, webhooks, Linux, browser or mobile use, or editing-suite plugins. EchoSubs is a desktop application: the workflow is local-file in, local-file out, because every cloud integration would require routing content through a third-party server, which contradicts the offline-only architecture.
Setup takes about five minutes; it requires a macOS 12+ or Windows 10+ computer and a video file, and no account is needed for the trial. The first result is a cleaned video saved next to the original. Step one: download the installer (~60 seconds). Step two: drag your video file into the app (~30 seconds). Step three: accept the AI-suggested detection parameters or tweak them (~5 seconds). Step four: click Remove and let the local GPU work (~3-5 minutes for a 5-minute 1080p clip). No account or sign-up is required to start the trial.
Yes. The subtitle generation feature runs in trial mode without a licence — the output carries a small watermark, useful for evaluating accuracy and language coverage before purchase. Subtitle removal and PPT/PDF-to-video features require a paid licence to run end-to-end. There is no time limit on the trial; you can keep evaluating the watermarked workflow as long as you want.
EchoSubs works fully offline once you have activated your licence. After the one-time online activation step, you can disconnect from the internet entirely and continue processing videos indefinitely — the AI inpainting models, transcription models, and TTS voices are all bundled with the app and run on your local hardware. Periodic licence re-validation happens silently in the background when the internet is available, but never blocks active processing.
EchoSubs runs on any macOS 12+ or Windows 10+ machine, but speed is GPU-bound. On Apple M1/M2/M3 or an NVIDIA RTX 3060-class or better GPU, a 5-minute 1080p video processes in about 2 to 3 minutes. CPU-only machines work too, but are 3 to 4 times slower for the AI inpainting step. There is no minimum RAM requirement beyond what the OS itself needs — the app streams frames rather than loading the whole video into memory.

OPINIONES DE CLIENTES
Para equipos que necesitan avanzar más rápido con video
Algunos comentarios de creadores, equipos de formación y agencias que usan EchoSubs en su trabajo diario.
Uso EchoSubs sobre todo con videos antiguos que ya tienen subtítulos incrustados. Me evita rehacer toda la edición y el procesamiento local funciona bien incluso con archivos largos.
