Descript

Fireflies.ai

Freemium

Fireflies.ai joins video calls as a bot, or records through a Chrome extension, desktop or mobile app, then turns the conversation into a searchable transcript with a summary, action items and speaker labels. It works with Zoom, Google Meet, Microsoft Teams and other platforms, transcribes in more than 100 languages and accepts uploaded audio or video files. AskFred answers questions across past meetings, and search spans the archive by keyword, topic or participant. Conversations can be pushed to CRM and project tools. Free accounts include limited AI summaries and 400 minutes of team storage.

AssemblyAI

Freemium

AssemblyAI sells speech models through an API rather than a consumer app. Developers send a file or live stream and get transcripts with timestamps, speaker labels, formatting and confidence scores; other endpoints summarize calls, detect topics and sentiment, or redact personal data. Its Universal speech models cover 99 languages, and a newer text-to-speech model targets voice agents. Billing runs per hour of audio processed, starting at roughly $0.15 per hour for pre-recorded transcription. The free tier covers about 185 hours of pre-recorded audio and 333 hours of streaming before charges begin.

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.

Synthesia

Freemium

Synthesia is built around studio-style videos made by an on-screen presenter. You choose from a library of stock avatars or record a personal one, type or paste a script, and the platform generates the footage with synced speech and gestures. Slide decks, video clips and images can be placed into scenes, and the same video can be dubbed into more than 140 languages with lip sync. Interactive branches, quizzes and SCORM export suit staff training as much as marketing clips. Editing happens in the browser, with brand kits and shared workspaces on higher tiers. The free plan covers ten minutes of video a month with a watermark.
