What's inside
Six subsystems, one window
Kacher is not a one-button downloader. It is a set of connected tools: downloads and queue, editor, batch transcoding, streams, private chat and connection diagnostics.
01
⤓
Downloads and queue
Download from your sources with format choice and a queue of dozens of tasks.
- Batch download, multi-select, format filters
- Pause, resume, re-download in another format
- Actual codec and size in the task card
02
✂
Built-in editor experimental
Timeline with preview frames and live effect preview in the same window. The youngest part of the app — we fix it from your feedback.
- Trim, ripple cuts, roll / slip / slide
- Effects, LUT, crop, logo removal
- Subtitles and local speech recognition
03
⚙
Batch transcoding partial
Hundreds of files in one pass: quality profile, hardware acceleration, folder structure preserved and a per-file report.
- NVENC / QSV / AMF / MF with CPU fallback
- Remux without re-encoding, FFV1, ProRes, DNxHR
- HDR passthrough, BRAW, silence cutting
04
◉
Stream recording
Confirmed live streams are recorded right away, with limits shown up front.
- Multi-threaded fragment recording
- Deduplication of one channel across addresses
- Stop keeps what has already been written
05
✉
Private chat
Direct and group conversations, files and voice between your devices. The server sees only meeting metadata, never the content.
- Channel encryption and fingerprint key check
- Files up to 8 GiB with integrity check
- Visibility modes: everyone / friends / invisible
06
⌁
Connection diagnostics
Nodes collected from open sources and checked before every request: you see which connection actually works and which only answers.
- Open lists and your own sources, SOCKS and HTTP
- Bulk check up to 500 nodes with cancel
- Selection by real speed, dead entry cleanup
Editor · experimental
An editor where you see what you get in progress
Timeline with preview frames and a preview rendered by the same filter chain as the final export. The editor is the youngest part — marked experimental openly.
Trimming without surprisesTwo marks, split here, delete a range with the rest collapsing, roll / slip / slide at seams.
Live previewMove a slider and see a frame with the same effects that go into the file. Continuous preview too.
Effects and keyframesBrightness, contrast, saturation, volume, animation over time, auto colour, stabilisation, LUT, crop, logo removal.
Subtitles and audioSubtitles by hand or local speech recognition; music and SFX with fades and ducking under voice.
Checked exportAfter render the codec, resolution, container, bitrate and audio track are verified and mismatches reported.

Batch transcoding
Hundreds of files in one pass partial
A folder of two hundred clips must not become an evening of manual work: take the folder, apply a profile, mirror the structure.
Quality profilesCodec, container, resolution, preset, fps, bitrate — and a remux mode that copies streams as-is.
Acceleration on your GPUAvailable encoders are detected; when the driver does not fit, we fall back to CPU and say so.
Colour and HDRHDR tags are carried over instead of being wiped; SDR gets a correct range conversion.
Silence cuttingFinds pauses, previews keep/cut marks and exports an EDL. Batch cutting supported.
A clear error instead of silenceUndecodable input is reported immediately; failure logs are kept.
Private chat
Messages and files — directly between devices
Direct and group chats, files, voice and stickers. The channel is encrypted and a connection must be confirmed first.
Fingerprint key checkEach device has a 32-character fingerprint: compare it in person.
Files up to 8 GiBA file is sent only after the recipient agrees; integrity is checked with SHA-256.
Voice and noise suppressionOne-to-one calls: Opus, three denoise engines and background gating.

Why local
Cloud services and a desktop app are different things
We do not sell access to someone else's content and do not resell files. Kacher is a tool for your own material on your own machine.
Online converters and cloud downloaders
- Your file goes to someone else's server and is processed there
- The service may limit, reject or delete your file
- Request and message history is stored by a third party
- Ads and partner placements
- Unclear what happens to your account after purchase
Kacher
- Download, editing and transcoding run on your computer
- The result stays in your folder under your control
- Messages and files go directly between devices
- No ads and no trackers inside the app
- Plan limits written as plain numbers
Three steps
From source to result in a minute
No sign-up for the sake of sign-up: the free plan works right after install.
- 1
Paste a link
Use the desktop app or collect links with the Chrome extension.
- 2
Choose the result
Pick quality, format and folder. Kacher shows what is available before starting.
- 3
Keep the file
Track progress in the queue and open the verified output when it is ready.

Responsible use
Rules that let you work with Kacher safely
This block defines what Kacher is responsible for and what stays with you as the account owner.
Your own and permitted content onlyMaterial you own, licence or have explicit permission for.
No circumventing content protectionThe app does not remove DRM or bypass technical protection measures.
Age and geographic restrictionsSource restrictions stay in force: the tool does not bypass them.
Source site rulesCheck the terms of use; if a platform forbids downloading, do not use Kacher for it.
Attribution and licencesCC-BY requires attribution; CC-NC and CC-ND restrict commercial use and derivatives.
Your responsibilityResponsibility for what you download and for respecting rights stays with the user.
Honest about limits
We do not promise what the app cannot do.
Professional codecs live in batchProRes, DNxHR and FFV1 are available in the batch profile; the built-in editor uses FFmpeg codecs.
Hardware acceleration depends on the driverWhen a GPU encoder is unavailable, work continues on CPU and the status says so.
AI upscaling is installed separatelyThe engine is downloaded with your consent, checksum verified, with a frame preview.
Speech recognition is local and not fastTranscription runs on CPU in an isolated environment: long videos take time.
Chat voice is one-to-oneThere is no group voice channel; text and files in groups work.
Designed for trust
Your data and your files are separated
Media files and links live on your PC, chat runs between your devices, payment data stays with the provider, and the licence lives on the app server.
- Files never leave the computerDownload URLs and output files are not sent to the licensing server.
- Chat goes directThe server sees that devices met, but not message or file content.
- Keys under OS protectionThe device private key is stored in the OS protected store.
- Payment secrets isolatedProvider keys are in neither the desktop app nor the extension.
- Licence bound to a deviceThe plan is issued after payment confirmation; moving is a couple of clicks in the account.
Questions before you install
Does Kacher work without a paid plan?
Yes. The Free plan includes daily downloads, standard quality and a limited amount of stream recording.
Where are files saved?
You choose the folder. Kacher shows the destination before starting and verifies the real output afterward.
Does the extension download files itself?
No. It collects links and passes them to the trusted desktop app, where limits and processing are enforced.
Can I move my license to another PC?
Yes. Open your account and request a device transfer from the linked devices section.
