77Fox browser extension: downloads, AI in-video ad blocking, OTP & translation

Keep intensive browser workflows in context while desktop, web, and extension maintain explicit data boundaries.

Video downloads

When a video has no captions, transcribe locally and export SRT.

Problem solved

Avoid link copying, dubious download sites, and manual subtitle cleanup.

Who it is for

AIGC creators, vibecoders, researchers, and heavy video users.

Works with the 77Fox dashboard

Files follow site-specific paths; archived subtitles can feed later prompt and asset work on the dashboard.

Privacy boundary

Media and transcription stay local. Use CUDA when available or CPU otherwise; uploading the video is not required.

AI in-video ad blocking

Problem solved

Conventional blockers cannot remove ads spoken inside the programme, while manual seeking loses content.

Who it is for

People who watch Bilibili, YouTube, tutorials, and AI material every day.

Works with the 77Fox dashboard

Cloud, local, and BYOK models share one extension workflow and status model.

Privacy boundary

Captions come first; missing captions are transcribed locally. Only the required text reaches the selected cloud, local, or BYOK model.

OTP delivery

Problem solved

Stop moving six-digit codes between phone, mail client, and browser.

Who it is for

Freelancers, multi-account operators, developers, and AI power users.

Works with the 77Fox dashboard

Desktop manages connections and status; the extension exposes short-lived candidates only where needed.

Privacy boundary

Codes are short-lived events. SMS and email bodies are not retained as long-term content.

Captcha recognition

Results are returned to the extension on your own machine, and the image itself never leaves it.

What it solves

Less manual typing for simple image codes, while keeping the failure path explainable.

Who it is for

Geeks and developers who log into consoles, test environments and multiple server panels.

How it fits the dashboard

The desktop app manages recognition state; the extension fills the field on the current page.

Privacy boundary

Images are processed locally only. Slider and click captchas take over the page temporarily just when needed and release immediately afterwards; a failed recognition ends there and never falls back to the cloud.

Page translation

What it solves

Keeps the original context when reading foreign-language docs, news and forums, without a translation plugin breaking the page layout.

Who it is for

Vibecoding users, AIGC creators, cross-language researchers and freelancers.

How it fits the dashboard

Translation flows straight into prompt assets, AI news and your daily board, with less copying and pasting.

Privacy boundary

Choose 77Fox cloud, your own key or a local model; the translation cache is kept for 30 days and the original page structure is never rewritten.

Page audio

Problem solved

Fix quiet audio, excessive bass, or unclear speech without changing system-wide output.

Who it is for

Heavy browser users, course viewers, creators, and audio-sensitive users.

Works with the 77Fox dashboard

Extension page audio handles tabs; desktop Audio control handles Windows output, microphones, and system chains.

Privacy boundary

A user gesture is required before capture. Processing stays on-device through Web Audio; audio is never uploaded.

Frequently asked questions

Does the extension require desktop?

Basic page features can work independently. Local helpers, SMS/email connections, transcription, and local models require desktop to be available.

What happens when a video has no captions?

Local transcription uses CUDA or CPU according to the machine and can archive the result as SRT.

Does AI in-video ad blocking upload the video?

No. It uses captions first and transcribes locally when needed; only necessary text goes to the selected cloud, local, or BYOK model.

Are message and email bodies retained?

No. Verification codes are handled as short-lived events; source bodies are not stored as long-term content.

If local captcha recognition fails, does it try the cloud?

No. Local recognition ends there and never falls back to the cloud.

Will page translation break the site?

No. Bilingual results are rendered by the extension itself without rewriting the original page structure, and the cache is kept for at most 30 days.

How is page audio different from desktop Audio control?

Page audio affects an authorised browser tab; desktop Audio control works with Windows output, microphones, and system devices.
