What ElevenLabs is
ElevenLabs is an AI audio company whose software turns text into speech and clones voices. Its products are grouped into three platforms: ElevenCreative for producing audio, ElevenAgents for building and deploying voice agents, and ElevenAPI for developers adding audio to their own applications. Voice generation supports a high degree of emotional expression, and voice cloning is a core capability, with ten professional voice clones included on the Business plan. Voice agents connect to telephony systems including Twilio and RingCentral, so an agent can hold a phone conversation rather than only running inside a web page. Around that sit integrations with CRM systems including Salesforce, Zoho and Pipedrive, customer support tools such as Zendesk and ServiceNow, scheduling and messaging through Calendly and Slack, payments through Stripe, and work data in Asana and Airtable. Zapier, Make and n8n are supported for automation, and agents can draw on real-time data while a conversation is in progress. Usage is metered in credits, and the rates differ by task. For V2 Multilingual models, each generated character costs one credit. Speech to text costs 330 credits a minute. Dubbing costs 2,000 credits a minute when produced automatically with a watermark, or 3,000 credits a minute without one. Credits reset at the start of each billing cycle, and unused credits roll over for up to two months. There is a free plan at $0. Starter is $6 a month for 30,000 credits and Creator is $22 a month for 121,000. Pro is $99 a month for 600,000 credits and adds 44.1kHz PCM output through the API alongside 192kbps audio. Scale is $299 a month for 1,800,000 credits across three seats, with team collaboration features. Business is $990 a month for 6,000,000 credits and ten seats. Enterprise pricing is custom, with credits, seats and priority support agreed individually. Paying annually costs ten months instead of twelve, and payment is by card, Apple Pay or Google Pay. ElevenLabs describes itself as an AI research and product company, and it runs a dedicated safety team with a multi-layered defence system intended to prevent misuse of synthetic voices. Its Impact programme gives free licences to nonprofits and to individuals who need the technology for accessibility.
What LangChain is
LangChain is a set of developer tools for building applications on large language models and then watching how those applications behave once they are running. Two pieces do most of the work. LangGraph is the framework, released under the MIT licence and free to use. LangSmith is the hosted service for tracing, evaluation and monitoring, and it is what the pricing pages describe. LangGraph ships built in memory that persists conversation history, human in the loop approval steps, and token by token streaming. Those are the three parts of an agent that are tedious to build by hand: remembering earlier turns, pausing so a person can approve an action before it happens, and returning output as it is produced rather than all at once. LangSmith records what a run actually did. Tracing SDKs cover Python, TypeScript, Go and Java, and the service ingests OpenTelemetry traces and works with the OpenAI SDK, the Anthropic SDK, the Vercel AI SDK and LlamaIndex, so it is not restricted to applications built with LangGraph. Tracing runs through an asynchronous callback handler and adds no latency to the traced application. Alerts can be raised through webhooks or PagerDuty. The Developer plan is free but capped at one seat, and includes 5,000 base traces a month before pay as you go charges begin. Plus is $39 per seat per month with no cap on seat count, 10,000 base traces a month and one free small serverless deployment. Base traces are retained for 14 days, and traces upgraded to extended retention are kept for 400 days. Usage past the allowances is metered: a compute unit costs $1.50 and a storage unit costs $1.00, deployments beyond the included one bill on vCPU hours and GiB hours, and tuned evaluators cost $0.01 in compute units per evaluation run on Plus. Enterprise is custom priced and billed on an annual invoice, adding custom single sign on, attribute based and role based access control, an SLA and a named support team. It is also where deployment opens up. LangSmith can run self hosted on a customer's own Kubernetes cluster, hybrid, or on the vendor's cloud, and the bring your own cloud option supports AWS, GCP and Azure. The managed cloud stores data in the GCP us-central-1 region, which matters if there are residency requirements to satisfy. LangChain states that it does not train on customer data.
