Reads your repositories to discover every API, scores and governs them, then exposes them to developers and AI agents via hosted MCP servers.

Spec-Free API Discovery: Elva scans repository code directly to find endpoints and generates OpenAPI 3.1 as output, so no existing spec is needed to start.
Endpoint Scoring: Every collection is graded on design, developer experience, AI readiness, security and performance, with the weakest collection surfaced first.
AI Fix Pass: A one-click agent writes missing descriptions from code, types response schemas and documents auth, then rescores the collection.
API Contracts: Per-audience contracts pin the exact endpoints and fields a partner, internal team, public developer or MCP client receives, excluding PII and internal fields.
Breaking Change Enforcement: Each commit is diffed against published contracts, showing the schema diff, affected consumers and tools, and blocking publish by policy.
Hosted MCP Servers: Contracts generate MCP servers hosted behind Elva's gateway with OAuth2, scoped keys, per-tool authorization and exportable call logs.
MCP Playground and Agent Feedback: Test the server with a live model, then read the complaints agents file about confusing or failing tools, scored back into the catalog.
Multi-Target Publishing: One approved contract ships as OpenAPI spec, Theneo docs, MCP server, Postman collection and a typed TypeScript SDK in sync.

API Inventory Audit: Discover undocumented or forgotten endpoints across a large codebase and get a ranked list of what to fix first.
Agent Enablement: Expose an internal service to Claude, Cursor or ChatGPT as a governed MCP server instead of hand-writing tool wrappers.
Partner Integration Safety: Publish a restricted contract to an external partner and have Elva block commits that would break their integration.
PII Scoping: Keep customer emails and internal ops annotations out of a public or agent-facing surface while the same endpoints serve them internally.
Zombie Endpoint Retirement: Prove no active consumer references an endpoint before deleting it, using contract and call-log evidence.
Enterprise Security Review: Satisfy SOC 2, ISO 27001 and GDPR questions and wire agent access into an existing SSO and SCIM identity provider.
Documentation Drift Control: Keep docs, SDKs and Postman collections regenerated from code on every merge instead of maintained by hand.

A browser-based AI teleprompter that uses real-time speech recognition to scroll your script at your actual speaking pace, in 60+ languages.

Voice-Tracked Scrolling: Real-time speech recognition fades out each word as it is spoken and keeps your place centered, replacing fixed-speed scrolling entirely.
Off-Script Handling: The prompter pauses when you improvise and automatically re-locks onto the text when you return, even if you skip to another section.
60+ Language Support: Works with English, Spanish, German, French, Swedish, Greek, and dozens more, including scripts that mix languages in the same paragraph.
Built-In Video Recorder: Record camera and mic takes directly in the teleprompter with the script overlaid on the video or shown in split-screen.
Local Recording Storage: Recordings save straight to your device and the script never leaves it; only audio is streamed for transcription.
Beam-Splitter Mirroring: Horizontal and vertical mirroring plus fullscreen output for professional hardware teleprompter screens.
Studio Reading Controls: Adjustable text size, column width, paragraph alignment, and black or white background for comfortable reading on set.
Usage-Based Billing: Only live microphone time counts toward the monthly hour allowance, and silence does not consume minutes.

YouTube Video Recording: Read a scripted video at a natural pace and cut multiple takes down to one while keeping eye contact with the camera.
Live Presentations and Demos: Jump between script sections during a live demo and have the prompter find your position each time.
Multilingual Content: Deliver a script that mixes two languages in the same paragraph without the prompter losing track.
Church and Event Media: Replace a hardware prompter and a volunteer operator with a prompter that reads along with the speaker.
Online Course Production: Record lecture segments where the speaker pauses often to find words, without a fixed scroll running ahead.
Podcast and Webinar Delivery: Keep sponsor reads and intros on script while sounding conversational rather than read.
