About SubEasy.ai
What Is SubEasy.ai
SubEasy.ai is a browser based AI subtitle generator and transcription platform. You upload a file or paste a YouTube or TikTok link, and the service produces a timed transcript plus a subtitle track you can edit, translate, and export.
The pitch is speed on the boring parts. Whisper style speech recognition handles the first pass, then the editor puts subtitle view and transcript view side by side so you fix wording in one place and keep timing in the other. Translation runs on top of that, and SubEasy markets it as context aware, which matters when a sentence only makes sense with the lines around it.
The limits are practical rather than technical. Everything runs in a browser, so there's no desktop app. Free accounts get three 30 minute transcriptions a day, and heavy users move to a credit based plan. API access sits on the Business plan, not on the entry tiers.
Getting Started
- Create a free account on subeasy.ai with email or a Google login.
- Upload an audio or video file, or paste a YouTube or TikTok URL to pull the media directly.
- Pick the spoken language, then let the transcription run. Turn on speaker identification if more than one person talks.
- Open the editor to fix names and numbers, run Subtitle Reflow to even out timing, translate if you need another language, then export SRT, VTT, or a burned in video.

Key features
Speech to Text Transcription
SubEasy.ai can transcribe audio to text with Whisper based recognition and reports accuracy of up to 99% on clean audio, a figure that comes from the company rather than independent testing. The Clear+ option rechecks the output and fixes misheard words and grammar. On noisy recordings, expect to correct more than the marketing numbers suggest.
Context Aware Subtitle Translation
Most translation tools work line by line, which is why pronouns and idioms come out wrong. SubEasy translates with the surrounding lines in view, so a word with two meanings lands on the right one. The company publishes side by side examples against Google Translate and ChatGPT to make that case.
Subtitle Reflow and Dual View Editor
Subtitle Reflow redistributes lines across the timeline when the original timing is uneven or when a translation runs longer than the source. The editor lets you work in subtitle view for timing and transcript view for wording, and changes carry between them.
AI Dubbing and Voice Cloning
Paid plans add dubbing and voice over, including a small number of voice clones depending on the plan. This is the feature to test on a short clip before committing a whole series, since synthetic voices vary in how natural they sound across languages.
Link Import and Hardcoded Subtitle Extraction
Paste a YouTube or TikTok address and SubEasy pulls the video, up to 4K on higher plans, without a separate downloader. If the subtitles are burned into the picture, OCR extraction rebuilds them as an editable track.
AI Companion for Transcripts
The AI Companion summarizes a transcript, drafts meeting minutes or notes, and answers questions about the content through a ChatGPT handoff. It also flags likely transcription errors, which saves a pass through the file before you publish.
Pros and cons
Pros
- Free tier is usable for real work: three 30 minute transcriptions every day, plus 60 minutes of AI translation daily.
- Translation quality holds up on conversational speech, where line by line tools tend to slip.
- Everything happens in the browser, so there's nothing to install and no platform lock in.
- Exports cover SRT, VTT, and burned in video, and paid plans remove the watermark and unlock 4K output.
- The AI Companion turns a finished transcript into notes or a draft without leaving the page.
Cons
- The credit system takes a while to understand, because daily free minutes and monthly plan minutes are counted separately.
- There's no mobile app and no offline mode, so a weak connection stops work.
- API access requires the Business plan, which rules out cheap automation for solo developers.
- Dubbing and voice cloning quality varies by language, so a voice that sounds right in English can sound flat in Japanese.
