Compliance Audit Trail
Who approved what. When. With what context. Immutable records for SOC 2, HIPAA, and regulated workflows.
AI Agent Traceability
AI agent acts. Human reviews. Both get the same structured record. The evidence chain enterprises need before trusting AI in production.
Activity Feed
A timeline of everything that happened in a document. Comments, edits, status changes, agent actions. Scoped to permissions.
Capture Everything. Then Slice It.
Explore activity across your org, drill into a single document, or filter by feature for focused views.
Query & Filter
getAllActivities() for org-wide or per-document. Filter by feature, user, agent, or time. Real-time or REST.
Immutable Mode
On by default. Records can't be changed or deleted. SOC 2, HIPAA, EU AI Act ready. Turn off when you need flexibility.
REST API
Create, query, and manage records from your backend. The SDK captures. The API gives you control.

Our Customers Trust Us
Teams ship Velt collaboration to millions of users every day.
Velt’s commenting & notification features are bundled with a lot of magic
Velt gave us 1-on-1 attention in our own private slack channel. The team was quick to add new features that we needed (thanks for the category feature!) We were extremely happy with how customizable Velt’s components were, allowing us to keep a cohesive look and feel to our product. Highly recommended.
Yuri KlebanSr. Product Manager @Google
Full collaboration features shipped in under 1 week
Building our own collaborative features was becoming an overwhelming task, so we were relieved when we found Velt. Their SDK included all the commenting and notifications features we needed, and were easy to integrate. We shipped comments in just a week, without having to build from scratch!

Increased engagement by 10% and helped ship 5x faster.
Took about a week for the implementation. The speed of iteration from the Velt team is incredible compared to alternatives, they're always happy to discuss and find a solution. The Velt team was extremely supportive and responsive to feedback. Docs were clear and easy to understand.

Saved 3 FTEs & will boost retention
Implementing Velt took weeks, not the quarters it would have taken us to build in-house, even with 3 FTE engineers. We're already seeing added value for our users and anticipate increased retention. Velt's product is slick, and their team is incredibly supportive.
Hope CallawaySr. Product Manager @Leadpages
Saved massive development effort
Velt provides the critical commenting functionality our customers rely on, saving us massive development effort. Migration from our previous vendor was seamless.
Fenne Buitenrust HettemaProduct Lead @Cloudfactory
With Velt we turned months of development into weeks of delivery.
We considered building this feature in-house. However, we quickly realized that creating a robust, scalable commenting system with all the modern collaboration features our users expect would require months of development effort and significant engineering resources, pulling our teams away from core innovation projects. That's when we discovered Velt.
Chris BakkeHead of Product @X
Boosted customer happiness.
Commenting is something that we knew we wanted in our app but with limited resources it wasn’t going to be prioritized. That is until we found out about Velt. The team was fantastic to work with.
Ethan VeresCo-founder and CTO @eqtble
We were able to launch 5x times faster than building from scratch.
Velt is a great product that sped up our feature development. It's saved us weeks of work.
Roman SevastCEO @Awesomic
With Velt, a single engineer could build comments feature in a few minutes.
Velt is outstanding! It helped us enable clear and quick communication with customers. With Velt, a single engineer could add comments in a few minutes without help from Product or Design. The docs were clear and straightforward. We spent only a few minutes making Comments work.
Weller MirandaSr. Software Engineer @Marco
Boosted engagement in our product!
It saved on engineering and the team is very quick on action! Keep up the responsiveness. We look forward to a long term partnership.
