Descript is an AI-powered video and audio editor that lets you cut recordings by editing their transcript, then clean up, caption, translate and repurpose the result. Underlord, its AI co-editor, plus Studio Sound, voice cloning and screen recording turn a single tool into a full production pipeline for creators and teams.
ZapCap is an AI video caption generator that transcribes speech in 100+ languages, renders animated captions and then automates the rest of the edit — B-roll, transitions, emojis, silence removal, sound effects and background music — so creators can publish captioned short-form video from a browser.

Text-based editing
Edit audio and video by deleting, rearranging or retyping words in the automatic transcript, with a full multitrack timeline available when you need it.
Underlord AI co-editor
Describe the edit you want in plain language and let the AI assistant assemble a tight cut, add clips and handle repetitive production work.
Studio Sound and speech regeneration
Remove background noise, level out voices, and fix misread lines with Regenerate Speech using a clone of your own voice.
Captions, translation and clip export
Generate subtitles and transcripts in a click, translate video into other languages, and reformat long recordings into shareable vertical clips.
強み・メリット
+Editing video by editing a transcript is dramatically faster than timeline scrubbing for interview, podcast and talking-head content
+Audio and visual AI features (Studio Sound, Eye Contact, Green Screen, Regenerate Speech) cover fixes that would otherwise need several tools
Recording, editing, captioning, translation and clip export all live in one workspace, reducing handoffs
+Remote Rooms recording and link-based review with time-coded comments suit distributed teams
+Strong enterprise story: SOC 2 Type II, SAML SSO, SCIM and GDPR-compliant data handling
制約・デメリット
–Heavy AI features and exports are gated behind paid plans, and free-tier limits are tight
–Long or complex projects with many tracks can feel heavier and slower than a dedicated non-linear editor
–Best results still come from clean source audio, so noisy recordings may need manual attention
–Advanced users who need granular effects and color work may still finish in another editor
–Billing is per seat, so costs add up quickly for large teams
ZapCap
ZapCap is an AI video caption generator that transcribes speech in 100+ languages, renders animated captions and then automates the rest of the edit — B-roll, transitions, emojis, silence removal, sound effects and background music — so creators can publish captioned short-form video from a browser.
Captions in 90+ languages
Automatic transcription covers 100+ spoken languages with frame-accurate timing, and captions can be rendered in 90+ output languages including dedicated CJK and Southeast Asian styling.
Animated caption styles and SRT export
Choose from 50+ animated caption styles, edit wording on the timeline, and export as MP4 with burned-in captions or download SRT, VTT and TXT subtitle files.
Automated editing: B-roll, transitions, sound
ZapCap inserts B-roll, applies transitions, adds emojis, images and GIFs, removes silences and filler words, and layers sound effects or background music to speed up the edit.
Project and throughput tiers
Manage up to 200 projects per month on the top tier, with per-video length limits rising from 1m30s on free to 10 minutes on Agency+ and processing speed up to 4x faster.
強み・メリット
+Automatic captions in a very wide language range with dedicated CJK rendering
+B-roll, transitions, emojis, silence removal and music handle much of the edit automatically
+Runs fully in the browser with no install, on desktop and mobile
+SRT, VTT and TXT export plus API access for localisation workflows
+Free tier with no credit card required for evaluation
+Explicit comparison pages against Submagic, VEED, Opus Clip and others
制約・デメリット
–Free tier caps videos at three per month and 1 minute 30 seconds per video
–Rendered video length is limited per plan, so long-form content needs a higher tier
–API access is an add-on with credits sold separately from the subscription
–Caption accuracy still benefits from a manual review pass on fast or accented speech
