Task Agents plan the work, visual workflows repeat it

What is VectorVein?
VectorVein is an AI project builder tool. A workflow platform pairing autonomous Task Agents with reusable visual workflows that produce reports, datasets, webpages and media. Includes organization-shared files, MCP publishing, bring-your-own model keys and an open-source desktop edition for workflows.
VectorVein is a workspace for multi-step AI work that ends in a concrete deliverable rather than a chat reply. Two engines sit side by side: a Task Agent that plans, acts, observes and revises its way through open-ended jobs, and a visual workflow builder for fixed input to process to output sequences that can run on a schedule. The two are not separate products. Agents can call configured workflows, and a published workflow can be exposed as an MCP Server for clients that speak the protocol. Outputs reflect the kind of work the platform targets: interactive HTML guides, flow maps, structured CSV datasets, research reports and short marketing video scripts. Public examples include a benchmark selection guide, a European accelerator and incubator database with 47 organization records, a Fed rate-cut research report, and an agent memory technology review. Files, Office and PDF documents, datasets, knowledge bases and media can all be fed into a run, and results land back in the workspace. Day to day, a run starts from a described outcome plus supporting materials. The task then breaks the work into steps, executes them in parallel where possible, retrieves material with source file paths so claims can be traced, and can be triggered by time or by task status. Anything verified can be promoted into a reusable workflow. Teams get organization, department and member management, with shared files usable directly inside Agents and workflows and outputs saved back to shared folders. Model choice is broad, spanning OpenAI, Anthropic, Gemini, DeepSeek, Qwen, Kimi, MiniMax, Zhipu GLM, Mistral, FLUX, Sora, Veo, Kling and Suno. Bringing your own API keys means those calls consume no platform credits. Entry points include a browser extension, an iOS app, a developer API, VApp publishing and the open-source desktop edition, which covers visual workflows only. Competitive ground is split with coding agents like Codex and Claude Code: VectorVein handles reports, datasets, webpages and media, and the two camps can be combined. For a single short answer, an ordinary chat tool is simpler.
How do you use VectorVein?
1Create an account and claim starter credits
Register on the homepage. New accounts receive 5,000 credits with no card required, which is enough to run several Task Agents and test workflows before committing.
2Describe an outcome and attach materials
Start a task by stating the deliverable you want, then add the files, datasets or references the Agent should work from. Planning and configuration do not consume credits; only runs do.3Review the plan, runs and sources
Watch the Agent move through plan, act, observe and revise. Check retrieved material against the source file paths it reports before accepting the output.4Turn verified steps into a visual workflow
Once a sequence proves reliable, rebuild it as an input, process, output workflow so it can be rerun on a schedule instead of re-planned each time.5Connect and publish through MCP or VApp
Register an MCP service for a Task Agent or publish a workflow as an MCP Server for compatible clients. Workflows can also be shipped as a VApp web application.
6Browse public cases for patterns
The community gallery shows real tasks with their deliverables, which is the fastest way to see what a well-scoped Agent run looks like before building your own.
Pros and cons
Pros
- Task Agents and visual workflows interoperate, so exploratory work can be hardened into a repeatable pipelineAI
- Deliverables are tangible files (HTML pages, CSV datasets, reports) saved to a shared workspace rather than chat transcriptsAI
- Own model API keys incur zero platform credits, with optional fallback to platform keys when a key is unavailableAI
- Organization, department and member sharing lets teams reuse the same files inside Agents and workflowsAI
- Open-source desktop edition and a developer API give a path off the hosted platformAI
Cons
- Credit consumption depends on which models and paid tools a run touches, so costs are hard to predict before runningAI
- Task Agents are hosted only; the open-source desktop edition is limited to visual workflowsAI
- The workflow and node model assumes some technical comfort, and the breadth of model and node options adds setup overheadAI
- Sharing a task exposes its description, execution records, tool calls and files to anyone with the link, including subtasksAI
- Codex compatibility is partial: Claude Code can call published workflows over the SSE MCP endpoint, while Codex remote MCP needs an adapterAI
How much does VectorVein cost?
Pricing
Credit based. Creating and configuring Agents and editing workflows is free; runs consume credits according to the platform models and paid tools used. Calls made with your own third-party model keys do not use platform credits, though your provider bills you directly. New accounts start with 5,000 credits.
Learn moreSupport
Setup and usage guidance lives in the documentation site, with model credit pricing documented separately. The homepage does not state live chat, email or SLA support terms.
