Synthesia

Murf AI

Free trial

Murf combines a browser voiceover editor with a speech API. In the studio you paste a script, assign a voice to each paragraph, adjust pitch, pace and emphasis, then export audio for video or e-learning. It offers over 200 voices across 30+ languages, plus AI dubbing for existing footage. The API exposes text-to-speech billed per 1,000 characters, speech-to-text at $0.24 an hour, voice changing and translation, with $10 of trial credit. Studio plans start at Creator; Business adds 96 hours of generation, 48 hours of transcription and a business license for teams.

CapCut

Freemium

CapCut is a browser, desktop and mobile editor whose free tier covers cutting, captions, transitions and templates. Paid plans add AI generation: text-to-video and image-to-video through Seedance models, background removal, automatic captions and a set of effects tied to the current app version. Edits happen on a multi-track timeline, and projects export at up to 4K. A credit system meters AI generations separately from ordinary editing, and extra credits can be bought when the monthly allowance runs out. Teams get shared spaces, a brand kit and per-seat billing, while solo creators stay on Pro.

Kling AI

Freemium

Kling generates short video clips from a text prompt or a still image. You can also drive an existing character with motion captured from a reference video, keep a person or object consistent across shots with element references, and extend a clip to roughly thirty seconds. The current model produces synchronized sound alongside the picture, and 4K export is available on paid tiers. A workspace holds your generations and their settings, and a free tier covers initial testing. Paid plans add monthly credits, faster queues, watermark removal and commercial usage rights.

Luma Dream Machine

Paid

Luma is a web app for generating and editing video from text, images or existing footage. You describe a shot, supply a reference frame, or upload a clip, and the service renders a short sequence that can be extended, restyled or relit. Its Ray model handles camera moves and character consistency across shots, while agent mode produces several variations of a brief at once. Third-party models are available in the same workspace, so you are not tied to one generator. Output suits ads, product shots and pre-visualisation. Plans are credit-based, starting with 10,000 credits a month.

Descript

Freemium

Descript treats video and audio as editable text. It transcribes your recording, and deleting a sentence in the transcript removes that section from the timeline, which makes trimming interviews and tutorials faster than scrubbing waveforms. Studio Sound cleans up room noise and uneven levels, filler words can be stripped in one pass, and the AI co-editor drafts cuts, scripts and clips on request. It also records screen and camera, generates voice clones, and dubs finished videos into other languages on paid plans. Business tiers add avatars and brand controls. The free plan includes an hour of media a month with watermarked exports.

HeyGen

Freemium

HeyGen turns a written script into a presenter-led video without a camera or studio. You pick a stock avatar or record yourself once to build a personal avatar, paste the script, and the tool generates speech with matching lip movement. Separate avatars and cloned voices can be produced for each language, so one recording can be published in Spanish, Japanese or German with the same on-screen presenter. A browser editor handles scenes, backgrounds, captions and imported slide decks. Teams can share templates and brand assets, and an API lets developers render videos programmatically. Free accounts get three watermarked videos a month, capped at one minute each.
