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.

Free

Free, open-source voice-to-text app for dictation, AI assistant, and voice writing across any app on Windows, macOS, and Linux.

Cross-App Dictation: Press a hotkey (Left Ctrl + Left Super by default) and speak — your words type straight into any app: email, editor, or chat, live as you talk.
Hey Flow Assistant: Say 'Hey Flow' to reply to a message, write an email, or draft a prompt without touching the keyboard; trigger name is renamable.
Live Translation: Speak Spanish, Hindi, French, Japanese, or any language and get clean English typed at your cursor, running fully on-device.
AI Cleanup: Strips 'um's and false starts, fixes grammar, and matches a chosen tone (Professional, Friendly, Concise, or custom) so speech reads polished.
Screen-Aware Answers: One hotkey summons a floating assistant that can look at your screen and answer about the error, chart, or email in front of you.
Private Memory & Profiles: Separate profiles per part of your day; remembers how you like to work locally without sending data off-device.
Cross-Platform Downloads: Ships as a Windows installer, macOS build (one Terminal command on first install), and .deb for Ubuntu and Debian.

Faster Writing: Developers, writers, and support agents dictate at 150+ WPM instead of typing at 45 WPM.
Multilingual Reply: Speak in your native language and reply in polished English without switching keyboards or translators.
Private On-Device Voice Work: Users who don't want their voice sent to a cloud get local dictation and translation.
Voice-Driven Prompts: Draft LLM prompts, emails, or Slack replies by voice inside any editor or chat app.
Screen Q&A: Ask the assistant about the specific error or chart on screen without pasting it in manually.
