You now have more control over how your agents retrieve knowledge. Customize the query your agent uses to search the knowledge base, and fine-tune the chunk size limit to better match your content. This gives you more precision, better answers, and smarter agents.

Your AI agents just got a massive upgrade:

🔥 What’s new

• Transcripts, reimagined – Replay calls, debug step-by-step, filter with precision, and visualize user actions like button clicks — all in a faster, cleaner UI.
• Evaluations, your way – Define what “good” looks like with customizable evaluation templates, multiple scoring types (rating, binary, text), auto-run support, and performance tracking over time.

📝 Transcripts

A full overhaul of the transcripts experience, built to help teams analyze, debug, and improve agents faster.

1. Call recordings – Replay conversations to hear how your agent performs in the real world

   

2. Robust debug logs – Trace agent decisions step-by-step

   

3. Granular filtering – Slice data by time, user ID, evaluation result, and more

   

4. Button click visualization – See exactly where users clicked in the conversation

   

5. Cleaner UI – Faster load times, more usable data

📊 Evaluations

Define what “good” looks like — and measure it, your way. Build (or generate) your own evaluation criteria, tailor analysis to your business goals, and iterate with confidence.

Eval types – support for:

1. ⭐ Rating evals (e.g. 1–5)
2. ✅ Binary evals (Pass/Fail)
3. 📝 Text evals (open-ended notes)

Also includes:

• Batch or auto-run – Evaluate hundreds of transcripts in a few clicks, or automatically as they come in

  

• Analytics & logs – See detailed results per message or overall trends over time

  

APIs

• We've release a brand new Evaluations API
• We've release a new Transcripts API
  • The legacy Transcripts API is still supported and currently has no deprecation timeline

🕓 Transition Period:
Until September 28, 2025, all transcripts will be available in the legacy view, for existing projects. On September 28th, 2025 the old view will be hidden and the new transcripts view will be the default. Transcripts older than 60 days will still be accessible via API for the foreseeable future.

Agents can now send emails seamlessly as part of any conversation. Whether it’s a confirmation, follow-up, or lead nurture message — the new Send Email tool makes it easy to automate communication right from your agent. Just connect your Gmail account and you’re ready to go.

Make sure to instruct your agent on how to use this tool properly. Give it a try in the agent step!

Seamlessly connect your voice AI agent to the real world with call forwarding.

The new call forwarding step lets your AI agent hand off calls to a real person (or another AI agent)—instantly and smoothly.

• ✅ Route to phone numbers
• ✅ Include optional extensions
• ✅ Support for SIP addresses

Build smarter, more human-ready voice agents—without sacrificing automation.

🛠️ You’ll find the call forwarding Step in the ‘Dev’ section of the step menu for now.
We’re planning to introduce a dedicated voice section soon—stay tuned!

Connect your agents to Hubspot to create contacts, leads and tickets.

Enable your agents to send SMS messages with an effortless connection to Twilio. Try it now in the agent step.

We’ve made building AI agents dramatically faster.

You can now generate a fully-functional agent by simply describing what you want it to do. No setup. No manual flow-building. Just write a detailed prompt — and Voiceflow will generate everything for you:

✅ Agent instructions

✅ Tools and workflows

✅ Conversation logic and components

This means less time configuring, more time testing and refining your agent behavior.

Today, we’re launching:

1. Prompt-to-project generation – go from idea to working prototype in seconds
2. Prompt-to-workflow generation – describe a capability, get a complete workflow
3. Prompt-to-component generation – create specific tools and logic on the fly

This is a foundational leap in how AI agents get built on Voiceflow - we can’t wait to see what you create.

Voiceflow now supports importing phone numbers from Vonage as an alternative to Twilio.
Vonage offers a minor latency improvement (~200-400ms) over Twilio, for more responsive calls.

Your Knowledge Base just got a major upgrade. With our new LLM chunking strategies, you can now prep your data for AI like a pro—no manual formatting needed.

We’ve introduced 5 powerful strategies to help structure and optimize your content for maximum retrieval performance:

🧠 Smart chunking
Automatically breaks content into logical, topic-based sections. Ideal for complex documents with multiple subjects.

❓ FAQ optimization
Generates sample questions per section, perfect for creating high-impact FAQs.

🧹HTML & noise removal
Cleans up messy website markup and boilerplate. Best used on content pulled from the web or markdown.

📝Add topic headers
Inserts short, helpful summaries above each section. Great for longform content that needs context.

🔍 Summarize
Distills each section to its key points, removing fluff. Perfect for dense reports or research.

These chunking strategies help you get more accurate, more relevant answers from your AI—especially for data sources not originally built for Retrieval-Augmented Generation (RAG).

Ready to make your Knowledge Base smarter? Try out some LLM chunking strategies and watch the results speak for themselves.

Note - LLM chunking strategies use credits. Before processing, we’ll show you a clear estimate of how many credits will be used—so you’re always in control.
