Contextual comments
Add threaded comments to elements, documents, cells, or canvases so feedback stays attached to the item being reviewed. The SDK includes comment components and tools.
Velt
Freemium
An embeddable collaboration and review SDK for apps that need comments, approvals, and agent-assisted workflows.
What is Velt?
Velt is an embeddable SDK for adding collaboration, review, and approval workflows to applications. Developers can place contextual comments on elements such as documents, cells, and canvases, and combine human feedback with review-agent activity. The product also includes approval flows, suggestions, notifications, and audit records, giving application teams building blocks for in-product review rather than relying only on external email or screenshot-based feedback. An admin console provides tools to monitor adoption, inspect live state and activity, browse or export records, manage feature settings, and deliver events through webhooks.
What can Velt do?
Approval flows
Define staged approval chains, including quorum and rejection paths. The workflow can wait for unresolved comments before advancing and notify reviewers in-app, by email, or in Slack.
Review agents and suggestions
Agents can add findings as comments, while suggested edits can be accepted or rejected by a person. Agent activity is represented alongside human activity in the review workflow.
Audit trail
Keep a timestamped record of review decisions, approvals, agent findings, and changes, with records available to browse and export.
Admin console and diagnostics
Monitor collaboration usage, inspect live SDK state and events, browse records, and configure features. The console also provides data export and a Chrome DevTools extension for debugging.
REST APIs and webhooks
Manage workspaces, API keys, domains, and configuration through platform-management APIs. Send events to webhook endpoints with signing, retries, transforms, and encryption.
Use Cases
“Review content in sales enablement platforms”
Let brand, legal, and client reviewers comment on decks, emails, and landing pages inside the platform, then route assets through approval before release.
“Add feedback to collaborative editors”
Embed anchored discussion in document, spreadsheet, canvas, or presentation interfaces so reviewers can discuss specific content rather than exchange screenshots.
“Gate AI-generated or AI-checked content”
Use review agents to flag potential brand or compliance issues and propose edits, while keeping a human acceptance or rejection step before changes take effect.
“Operate a production review layer”
Use the console to investigate activity, debug live integrations, export records, and configure review features for an application.
