AI Voice & Text Agents That Don't Break Mid-Call
Langoedge is a visual builder for AI phone and text agents. No n8n, Vapi and webhooks to stitch together. If a booking slot is taken, your agent tries the next one. It checks its own work before anything is booked, and every call is scored when it ends. Phone line and 3,000+ apps included.

Your agent doesn't give up when plan A fails.
Most voice platforms run a straight line. The moment reality doesn't match the script, the caller gets an apology and a dial tone. Langoedge compiles your canvas into a real state machine, so an agent can double back, try again, and finish the job.
Loops instead of dead ends
Slot taken? The agent routes back and tries the next one. A flow can loop back on itself, so recovery is a normal path through it rather than an error you have to code around.
A check before it acts
Before anything is booked or sent, a quality gate asks a yes/no question about the agent's work. Is the slot inside opening hours? Did the caller confirm? If the answer is no, the agent goes back and fixes it. You can also make a person sign off first.
Picks up where it left off
Every step is saved as it happens. If a conversation is interrupted, it resumes from the last good point instead of starting over.
Linear script
The usual outcome
- Caller asks for 3:00pm
- Slot is already booked
- “Sorry, I can't help.”
Call lost
Langoedge flow
Same problem, handled
- Caller asks for 3:00pm
- Slot is already booked
- Check next opening — 3:30pmLoops back
- Booked, confirmation sent
Appointment booked
Tested before launch. Scored after every call.
Checks and call scores run on JEV, a model from TypeSafe built for pass/fail decisions and scoring. It isn't a chatbot marking another chatbot's homework. Each check returns a pass, a fail or a score, with how confident it is, so the same call gets the same grade every time.
The work happens while the agent keeps talking.
A voice agent that stops to think sounds broken. Langoedge keeps the conversation moving and does the heavy lifting in the background, so your caller hears someone doing their job, not a machine buffering.
Slow work runs in the background
Updating your CRM, looking up records, or waiting on another system happens in the background while the call carries on.
No dead air
While a tool runs, the agent covers the gap with natural conversational filler and ambient sound instead of an unnerving silence.
Work continues after hang-up
The moment a call ends, the transcript can trigger a follow-up flow: notes written back, a recap texted, the next task created.
Remembers across conversations
Switch on long-term memory and the agent keeps preferences and context between conversations instead of starting cold every time.
Connect anything
Connect the tools you already run. Write no glue code.
Adding a new tool to an agent should be a setup step, not an engineering project. On Langoedge it is.
3,000+
apps your agents can use — switched on, not coded
This isn't a fixed list we maintain by hand. It updates itself, so new apps are available to your agents straight away. Gmail, Slack, HubSpot, Airtable, Google Sheets, your CRM: connecting one is a few clicks, not a sprint.
We keep our own copy of every app's tools, so your agents keep working even if the source is briefly unreachable.
Native integrations
Deep, hand-built support for the systems these industries actually run on.
- Cliniko
- ServiceM8
- Twilio
- Telnyx
- Pinecone
- Qdrant
Purpose-built where it counts
Where a standard connector isn't good enough, we build the integration ourselves: Cliniko for practices, ServiceM8 for trades, and Twilio and Telnyx for the phone network.
Your own data, your own accounts
Agents can search your own documents, stored in your own Pinecone or Qdrant account. Connect your own AI provider too, so sensitive data stays on accounts you control.
An escape hatch for developers
Custom Python nodes and raw HTTP calls sit on the same canvas as everything else. No-code is the default, not the ceiling.
Built for
A general platform, with specialist depth.
Langoedge builds any agent you can draw. These three sectors are the ones we know best. For healthcare and trades, we built the integrations ourselves, so the agent works with those systems from day one.
Healthcare

Answer every call to the practice, find the patient, book or move the appointment, and write the summary back once the caller hangs up.
- Book, move, and cancel appointments
- Look up existing patients on the call
- Post-call notes written back automatically

Early results.
From the first teams putting Langoedge agents to work.
“Our Langoedge AI agent for creating vendor reports has completely transformed our workflow. We were able to save over 15 hours per report, allowing our sales team to focus entirely on closing properties.”
“Integrating Langoedge's Voice AI into our research projects has been incredibly rewarding. The natural voice interactions provided realistic simulation environments that were highly beneficial for training our trainees.”
Head to head
Langoedge vs. voice bots, n8n + Vapi, and custom builds.
Every option below can answer a phone. The differences show up on the calls that don't go to plan.
| Category | Off-the-shelf voice bot | n8n + Vapi stack | Custom build | Langoedge |
|---|---|---|---|---|
| When the plan fails | Apologises and ends the call. You find out from the voicemail. | The webhook errors and the caller hears silence. | Whatever recovery logic someone remembered to write. | Loops back, tries the next option, and escalates to a human only when it is genuinely stuck. |
| Response speed | Usually acceptable, and nothing you can do about it when it isn't. | Every tool call is a webhook round trip the caller waits through. | Fast if you build it right — and months before you find out. | Direct SIP trunking plus background sub-flows, built to a sub-1.2 second target. |
| Seeing what it did | A recording and a hunch. | Three dashboards to correlate before you find the failure. | You build the observability layer too. | One timeline per run: the transcript, the branch it took, and every tool it called. |
| Testing it | Ring it yourself and hope. | Manual test calls, no scoring, no regression safety net. | Build a test harness before you can trust a single change. | Simulated callers before launch, and every call scored afterwards against test cases written from the agent's own instructions. |
| What it costs | Per-seat pricing that climbs every time the team grows. | Three subscriptions: workflow tool, voice platform, model provider. | Salaries and maintenance that never stop. | $0.08 AUD a voice minute and $0.002 AUD a tool call, after 100 free tool calls a month. No base fee, no seats, no contract. |
Langoedge pricing: pay per minute, not per seat.
Only pay for what you actually use. No hidden fees or lock-in contracts.

Frequently asked questions
The things people ask before they build their first agent.
Langoedge is a visual builder for AI agents that answer phone calls, texts and website chat, and do real work in your business systems. You draw the conversation on one canvas, and Langoedge runs it on real phone lines. The same agent can sit behind a phone number, an SMS thread, a chat widget or your own app. There is no separate workflow tool, voice platform and glue code to keep in sync.
In a stitched-together stack, the voice platform has to ask the workflow tool for every answer over a webhook, then wait. That wait is where dead air and lost context come from. In Langoedge, the conversation, the tools and the phone line live in one place, so nothing waits on another system. You also get one log of each call instead of three dashboards to piece together.
The agent recovers instead of hanging up. Most voice platforms follow a fixed script: if the slot the caller wanted is taken, the agent apologises and the call ends. A Langoedge agent goes back, offers the next available slot, and only hands over to a person when it genuinely can't help. Before anything is booked, a quality gate checks the work against a rule you write. If the check fails, the agent tries again, up to a limit you set.
Agents are tested by simulated callers before launch, and every real call is scored after it ends. Langoedge writes the test cases from your agent's own instructions and rolls the results into a pass rate and a quality score. The scoring runs on JEV, a model from TypeSafe built for pass/fail decisions and scores. It isn't a chatbot grading another chatbot, so the same call gets the same grade every time.
Over 3,000 apps through Pipedream Connect, including Gmail, Slack, HubSpot, Salesforce and Google Sheets. Adding one is a setup step, not a coding project. Some systems get integrations we built ourselves: Cliniko for healthcare practices and ServiceM8 for trades. Agents can also search your own documents, call any web API, and run custom Python code.
Langoedge is built to reply in under 1.2 seconds. It connects straight to the phone network through Twilio and Telnyx (direct SIP trunking), with no reseller in between. Slow work, like updating a CRM, happens in the background so the conversation keeps moving. When a lookup takes a moment, the agent uses natural filler and background sound instead of going silent.
Yes, you choose. There are more than 100 voices with Australian, American, British and other accents, in English and other languages. You can change the voice for each agent without touching the rest of the flow. You can also use a cloned voice, so callers hear your founder, your receptionist, or whoever already represents your business.
No. You build, test and launch an agent by dragging and dropping, and most agents go live in a single session. Developers aren't boxed in, though: custom Python and direct API calls sit on the same canvas as everything else.
You can start free, then pay only for what you use. The free tier includes unlimited text messages and document search, 100 tool calls a month, and 5 minutes of voice testing in your browser. Text and search run on your own AI provider account, so you pay that provider directly with no markup from us. After that, it's $0.08 AUD per voice minute and $0.002 AUD per tool call. There's no base fee, no per-seat pricing and no lock-in contract.
It's built with enterprise controls in mind. Every request is authenticated, and each account's data is kept separate from every other account. Traffic between our services is signed, and an agent can't be tricked into contacting places it shouldn't. Every step of a call is recorded, so you can see what the agent knew, what it decided and which tools it used. For specific compliance needs, email info@langoedge.com before you deploy.
