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.
Slice Knowledge is a private, deployable AI environment that converts internal documents, recordings and expert know-how into SCORM-compliant courses, then delivers them through a single AI agent that answers questions, runs practice simulations and personalizes each employee's learning path.

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
Slice Knowledge
Slice Knowledge is a private, deployable AI environment that converts internal documents, recordings and expert know-how into SCORM-compliant courses, then delivers them through a single AI agent that answers questions, runs practice simulations and personalizes each employee's learning path.
Zero-effort content conversion
Upload documents, recordings, wikis, webinars or web pages and Slice automatically assembles them into complete, SCORM-compliant courses — the vendor claims roughly 80% less content-creation time.
Expert knowledge capture
Subject-matter experts simply talk or upload recordings; Slice transcribes, structures and makes that tacit knowledge permanently searchable so it is not lost when people leave.
Role-based adaptive learning paths
The platform detects a learner's role and current knowledge level and continuously adjusts a personalized path instead of serving one fixed curriculum to everyone.
One agent for knowledge, training and practice
A single private AI assistant answers questions, launches full courses inside the chat, runs simulations and coaches learners through to mastery.
強み・メリット
+Converts existing internal material into SCORM courses automatically
+Private on-prem or private-cloud deployment keeps sensitive data in-house
+Adaptive, role-aware learning paths rather than one-size-fits-all courses
+Single agent covers Q&A, coursework and practice simulations
+Free 30-day pilot for decision makers to test on real data
制約・デメリット
–No public pricing — every enterprise deal requires a sales conversation
–Large-scale deployments need IT involvement for private/on-prem hosting
–Best value depends on already having substantial source material to convert
–No self-serve free tier for individuals or small teams
