[ Realtime AI Development ]
AI That Responds While the Moment Still Matters
We build AI that works on live streams: voice calls, video feeds, market ticks, clickstreams and sensor events. Responses arrive in hundreds of milliseconds, not after the customer has hung up or the transaction has cleared.

The Realtime AI Path
Every layer has a latency budget. We measure each one so slowdowns can be traced to a single hop.
- Hop 1
Clients and channels
Where live audio, video and events originate.
- Web and mobile apps
- Phone and SIP
- IoT devices
- Hop 2
Realtime transport
Moves media and events with minimal delay.
- WebRTC SFU
- WebSockets
- LiveKit
- SIP trunks
- Hop 3
Stream processing
Buffers, enriches and routes events to the right model.
- Kafka
- Flink
- Redis Streams
- Voice activity detection
- Hop 4
Low-latency inference
Models served for fast first tokens and steady throughput.
- Realtime model APIs
- vLLM
- Streaming STT and TTS
- GPU autoscaling
- Hop 5
State and observability
Session context, results and latency tracing.
- Session store
- Latency traces
- Recording storage
- Alerting
Where Latency Decides the Outcome
Realtime AI is worth the extra engineering when a slow answer is the same as no answer.
01Live voice agents and call assist
Speech-to-speech agents that hold natural conversations, plus agent assist that suggests answers and pulls records while a human is still on the call.
Callers get answers without awkward pauses
02Live transcription and translation
Streaming captions and two-way translation for calls, meetings, events and broadcasts, with speaker labels and custom vocabulary.
Conversations across languages in real time
03Transaction and fraud scoring
Models that score payments, logins and signups inside the request path, returning a decision before the user sees a spinner.
Risk checks that do not slow checkout
04In-session personalization
Recommendations and offers that react to what a visitor is doing right now, computed from clickstream events in seconds.
Relevance based on this session, not last week
05Live market and sensor signals
Streaming anomaly detection and summaries on market data, IoT telemetry and logs, with alerts routed to the right person.
Problems caught while they can still be fixed
06Live commerce and streaming moderation
Realtime chat moderation, product tagging and highlight detection for live shopping streams and community broadcasts.
Safer streams with less manual moderation
Engineering for Every Millisecond
Low latency comes from the whole path: transport, models, infrastructure and how results are streamed back.
WebRTC and media transport
Browser, mobile and SIP audio and video over WebRTC, with echo cancellation, jitter buffers and network recovery.
Edge and regional routing
Media servers and inference placed close to users, with fallback regions when one becomes slow.

I had the pleasure of working with Sajal Tech on a travel website, and it was an incredible experience from start to finish. They demonstrated professionalism, clear understanding of requirements, and excellent communication throughout.

Three to five days
Start With a Latency Budget Workshop
We map every hop between your user and the model, set a target for each, and tell you which parts of the path will decide whether it feels instant.
Book the WorkshopRealtime AI by Industry
Where a slow answer is the same as no answer.

Voice agents and agent assist on live calls, with SIP trunks, recording consent and latency tuned per region.
- Voice agents
- Live agent assist
- Call transcription
Telecom and contact centersLive AI With Safeguards
Realtime systems act before a human can review, so the checks have to run inside the stream.
- Safeguard 1
Inline safety filters
Streaming moderation and policy checks run on partial outputs, so unsafe content can be stopped mid-sentence.
- Safeguard 2
Consent and recording rules
Call recording notices, consent capture and region-specific retention are built into the session flow.
- Safeguard 3
Load-tested before launch
We replay realistic traffic and network conditions, and only launch when p95 latency and error rates meet the agreed budget.
- Safeguard 4
Secure media handling
Encrypted media in transit and at rest, scoped tokens per session and an ISO 27001 certified team handling your streams.
How We Ship Realtime AI
We measure latency from the first prototype, because it is very hard to add speed after the architecture is set.

Realtime AI Questions
Still deciding? A 30-minute call usually answers the rest.
Ask Us DirectlyFor voice conversations we usually target a p95 turn latency under one second, which feels natural to most callers. Streaming captions can appear in a few hundred milliseconds, and fraud scoring in the request path often needs well under 100 ms. We set the target with you and measure it from the prototype onward.
A working prototype starts from $2,500, a production feature from about $15,000 and a multi-region platform from $45,000. Running costs are mostly per audio minute or per event, and we estimate them before you commit.
Speech-to-speech APIs like OpenAI Realtime and Gemini Live give the lowest latency and the most natural turn-taking. A separate pipeline gives more control over each step, custom vocabulary and voice choice. We prototype both when the choice is not obvious.
Yes. We build consumers that enrich events, call models and publish results to new topics, with backpressure, retries and dead-letter queues. Your existing producers do not need to change.
We set timeouts per hop and fall back to a faster model, a cached answer or a simpler response path. Monitoring alerts us when p95 latency drifts, and traffic can shift to another region or provider.
Yes. We connect SIP trunks and providers like Twilio alongside WebRTC for browsers and mobile apps, so the same AI can serve calls, apps and web widgets.
Streaming speech models handle most accents well, and we add custom vocabulary for product names and technical terms. We measure word error rate on recordings from your own callers before launch.
Yes. Open-weight speech and language models can run on your GPUs with vLLM or Triton, which helps with data residency and cost at high volume. We size hardware from your peak concurrency.
You own the code, infrastructure definitions and configuration. We hand over runbooks and load test scripts so your team can operate and scale it.
