AI That Works the Way You Do
If you can think it, you can probably build it. Devs or no Devs, SDK or UI, take your pick.
Build conversational assistants that actually get work done — from customer support triage to internal helpdesks, powered by context and memory.
Building with AI shouldn’t feel like a spray-and-pray
No more stuck flows or squeaky hacks — just a clean, integrated space to design, test, and ship AI systems with confidence.
Prompt & Version Control
Update prompts, change steps, add your notes and iterate with confidence, thanks to one click point in time restoration of your Melds. Save drafts and publish only when you're ready.
Testing & Debugging
Execute each step one at a time or all together and setup mock data for testing throughout. View the run logs in real time, and inspect every input and output.
Seamless Connectivity
With over 300+ apps already integrated, and built in vector searchable data tables, you can link your existing tools and context with no code in no time.
Hosting, Security & Observability
Take your ideas and prototypes to secure production grade solutions thanks to our low latency and high visibility cloud platform. Everything you need to track, monitor and alert on your AI applications straight out of the box.

Checkout everything Meld has to offer grouped by each of our core capabilities
Visual Builder
Design flows visually with drag-and-drop logic blocks — no code required, but code welcomed if that's your thing.
Custom HTTP Requests
Call any REST API (including any unsupported apps, or even your own software) with full control over method, headers, body, and auth.
Templates
Kickstart faster with prebuilt Melds and common tool patterns that can be customised instantly.
Project Scopes & Folders
Organise Melds however you like, by categories, teams, departments, integrations or separate across different projects all together.
Conditional Paths
Branch your logic based on inputs, model responses, or system state to build adaptive flows, or have the Meld decide for you!
Code Blocks
Write custom code to transform inputs, calculate values, or add logic where needed. Use the embedded AI code assistant to speed you up or do it for you!
Variables & Storage
Define and reuse dynamic variables across flows for logic control and temporary or permanent states.
Web Search & Scrape
Retrieve real-time content from public web pages and search engines on demand.
Data Tables & Vector DB
Store structured data with built-in search, filtering, and automatic embeddings for efficient AI use.
Chat Interface & Forms
Add conversational interfaces, or data collection forms to any flow for interactive internal or user-facing experiences.
File Handler
Upload, read, parse, save and act on PDFs, CSVs, images, or other file types as part of a Meld.
Webhooks
Start a flow with external events via RESTful webhook endpoints.
300+ App Integrations
Trigger flows or sync data from popular tools like Slack, Notion, Hubspot, and more.
Data Loops
Iterate through arrays, tables, or API results — great for batch tasks or async execution.
Step-by-Step Testing
Test flows interactively with stepwise execution and visible inputs/outputs at each stage. See exactly what happened when and why.
Retry Errors
Configure automatic retries for transient or recoverable failures and restart failed runs after fixing the issues.
Tagged Runs
Label and organise your flow runs for easier debugging, grouping, post-run logic or tie back to your external systems and audits.
Versioning
Clone, compare, and revert changes to flows and prompts as you iterate — no more breaking updates or forgetting what worked. Keep as draft or publish when you're ready.
Custom Tool Flows
Don't just connect to your third party apps, build and refine exactly how your AI will interact, its access controls and what data it sees.
Scheduling
Run flows on a timed basis — hourly, daily, weekly, or custom CRON expressions.
Monitoring & Alerts
Set up real-time alerts for errors, or respond to tasks created by the human in the loop feature.
Human in the Loop
Route to human reviewers before executing high-risk or important actions.
User Access Controls
Permission who can view, edit, or run flows with role-based access across individual projects, with individual connections.
Run Logs
Inspect every step of every run with input/output history, timestamps, and status.
BYO Data Store
Provide us with an Amazon S3 bucket and we'll store all your run logs in your control, on your terms.
Setup your Meld in 5 easy steps
Whether it’s a Slack bot, automated report, or multi-agent human-in-the-loop system, Meld gets you from “what if” to "no wayyy" in a blink.
Apps for everyone in your organisation
Over 300+ integrations and the ability to add unlimited of your own via API, any one in your team can connect their SaaS applications
AI you can trust, systems you control.
Meld addresses the most common concerns about AI adoption with enterprise-grade safety, data privacy and control features built-in.
