March 2026

Built-in browser, task flows, redesigned layout, saved prompts, mermaid diagrams, draft PRs, and document preview

March 2026 — Zenflow Updates

March was a huge month for Zenflow. We shipped a built-in browser, task flows, a completely redesigned app layout, saved prompts, and a lot more. Here’s everything that landed.

New Features

Built-in Browser

Preview and Iterate on Web Apps

Preview web apps, reference UI elements, and iterate on them directly with the agent — all without leaving Zenflow.

The built-in browser lets you:

• Preview web apps running on localhost or any URL
• Reference elements or regions and ask the agent to make changes
• Browser MCP tools let agents automate interactions, capture screenshots, and control the browser programmatically
• Viewport presets — switch between Responsive, Mobile, Tablet, Desktop, and Wide with zoom support
• Open in external browser when you need the full experience

Task Flows

Autonomous Goal-Driven Agents

Give the agent a goal — it keeps working toward it on a schedule until the goal is achieved.

Task Flows are a new way to let agents work autonomously over time:

• Shepherd a PR through review — the agent watches for comments, addresses feedback, and pushes fixes
• Watch CI and fix failures — the agent monitors your pipeline and auto-fixes issues
• Keep a branch rebased — the agent handles merge conflicts so your branch stays up to date
• Set any custom interval for how often the agent checks in

Redesigned App Layout

New Three-Panel Architecture

Side-by-side chat and content panels with a collapsible tools panel for Steps, Changes, and Files.

The new layout gives you:

• Top header bar with quick access to key actions
• Side-by-side panels — chat on the left, content on the right
• Collapsible tools panel for Steps, Changes, and Files
• Improved diff viewer with better colors for readability
• File attachments — drag & drop, paste, or pick files with click-to-preview for images

---

Saved Prompts

Reusable Prompt Shortcuts

Create prompt shortcuts and insert them anywhere by typing /.

Save your frequently used prompts and insert them in chat or task descriptions with a quick / command. No more retyping the same instructions.

---

Document Preview

Open Docs Right in Zenflow

Preview PDF, DOCX, XLSX, CSV, and PPTX files directly in a tab.

• Open documents with zoom controls and multi-sheet support
• HTML files open automatically in the built-in browser
• Great for reviewing specs, reports, and data files alongside your code

---

Mermaid Diagrams

Diagrams in Chat

Ask the agent to render architecture, flow, and sequence diagrams inline.

Agents can now generate and render Mermaid diagrams directly in chat or markdown — perfect for visualizing architecture decisions, data flows, and sequence diagrams.

---

AI-Managed Commits

Hand control of commits to the agent — it commits when it makes sense, not after every turn. Less noise in your git history.

---

Draft Pull Requests

Create draft PRs directly from the “Create GitHub Pull Request” dialog. Ship when you’re ready.

---

Ask Tool Questions Mid-Task

Agents can now pause and ask you questions during a task, then continue once you answer. Questions appear inline in the chat between agent messages.

---

Spotlight File Search

Find files fast with fuzzy-ranked search and a built-in file tree explorer. Quickly browse files across your entire project.

---

Integration Discovery

Agents detect when an integration is missing and prompt you to connect it inline — no more hunting through settings.
