All tools
Everything runs locally in your browser using WebAssembly, Web Audio, Canvas2D, and similar in-browser APIs — nothing you open here is uploaded. A few tools optionally load a public model or engine (translation, OCR, video processing) from a CDN into your browser on first use; that's a real, sizeable download, and it's noted on each of those tool's pages.
Audio & video utilities
Subtitle fixes, loudness mastering, and watermark cleanup — no per-minute cloud charges.
Subtitle translator & SRT fixer
availableStop re-timing subtitles by hand.
Timing/wrap runs everywhere; translation needs a WebGPU browser and uses a local LLM instead of a per-minute transcription API.
Timing/wrap: works everywhere. Translation: needs a WebGPU browser.
Open toolAudio mastering (LUFS normalizer)
availableGet podcast-ready loudness without hiring an engineer.
Hits a target loudness (e.g. -14 LUFS for Spotify/Apple Podcasts) with a true-peak limiter, entirely in your browser.
Open toolBulk video watermark remover
availableClean up a whole batch of clips in one pass, not one at a time.
Mark a watermark's position once, apply FFmpeg's delogo interpolation filter across a batch of clips.
Interpolation-based, not AI inpainting — see the tool page for what that means.
Open toolPrivacy-first document tools
Built for teams who can't upload client files to a third-party server — legal, HR, finance.

availableRedact sensitive documents without a compliance review of a third-party tool.
Pixels are removed before export, not just covered — plus optional OCR search to help you find text to redact.
Open toolInvoice data extractor
availableTurn a shoebox of receipts into a spreadsheet in minutes, not an afternoon.
Drop in a folder of receipts and export a clean, editable CSV of vendor, date, and total.

Placeholder slots — replace with real customer quotes as they come in. A specific result ("saved us 6 hours a week") is far more persuasive than generic praise.
