BiBimba

mamama, inc.

Paid

A keyboard-driven Mac clipboard manager that OCRs screenshots and runs on-device AI to translate, summarize or rewrite what you copied.

Unified Clipboard Search: One search covers copied text, images, text recognized inside screenshots, and saved snippets, so you do not need to remember where something came from.
Automatic Screenshot OCR: Text in screenshots and copied images is read automatically, and a detected table can be converted to Markdown, JSON or HTML.
On-Device Text Actions: Translate, summarize, rewrite as a business email, turn into a bullet list, or reformat a table using on-device AI on compatible Macs.
Saved Custom Instructions: Store your own prompts as reusable actions and fire them on the current selection from the keyboard.
Pick and Paste: Choose an item from history and paste it directly back into the app you were using, either formatted or as plain text.
Global Keyboard Shortcuts: Dedicated shortcuts open history, pick-and-paste, snippets, screenshot capture, screen OCR and text actions without touching the mouse.
Local Retention Controls: History lives on your Mac with a configurable item count and age limit, automatic pruning of older entries, and manual deletion at any time.
Ten Interface Languages: Ships in Japanese, English, Simplified and Traditional Chinese, Korean, Spanish, French, German, Portuguese (BR) and Arabic.

Receipt and Invoice Capture: Screenshot a receipt, let OCR read the total, and search for it weeks later by amount or vendor.
Table Extraction: Turn a table captured in a screenshot into Markdown or JSON without retyping it into a spreadsheet.
Cross-Language Correspondence: Copy an incoming message, translate it on-device, and paste the reply back into the same app.
Email Polishing: Rewrite a rough draft into a business-email tone from the keyboard while staying inside the mail client.
Research Collection: Build a searchable archive of copied quotes, links and screenshots from a browsing session and retrieve any of them by keyword.
Confidential Work: Keep clipboard history and AI processing on-device so sensitive copied material never leaves the Mac.

Noveum

Freemium

Sends synthetic users at your voice and chat agents over real SIP calls and LiveKit audio, with personas, interruptions and adversarial intent.

Real Telephony Calls: Dials your agent over SIP through Twilio, Plivo or Vobiz and LiveKit real-time audio, exercising real phone-network latency and audio rather than a mocked transcript.
Systematic Persona Generation: Builds callers with goals, moods, accents and interruption behavior from your own agent context, instead of hand-authored scripts that go stale on every prompt change.
Adversarial Scenarios: Includes prompt-injection probes, barge-in, silence and mid-sentence topic switches to test safety boundaries, refusal behavior and turn-taking recovery.
Batch Matrix Runs: Runs the full persona-by-scenario matrix under a shared batch id for combinatorial coverage, grouped and comparable in one place.
Concurrency and Load Testing: Raises concurrency up to 2,000 simultaneous lines to find how many calls an agent can actually hold at once.
Tool Virtualization: Replays reads and sandboxes writes so a changed decision runs end to end while writes never reach production systems.
Trace Capture and Scoring: Captures every synthetic call as a full trace including the audio, scored with 30+ voice AI metrics and 100+ across the platform.
Broad Endpoint Support: Connects to SIP, LiveKit, Pipecat, LangChain/LangGraph, the OpenAI and Anthropic SDKs, chat over HTTP, or custom agents via SDK hooks.

Pre-Release Rehearsal: Point NovaSynth at a staging SIP number or an unshipped agent and surface failures before any customer hears them.
Regression Testing After Prompt Changes: Re-run the same persona matrix after a prompt or workflow edit to confirm a fix held and nothing else broke.
Safety and Injection Testing: Probe whether an agent leaks its system prompt or tool definitions under adversarial callers.
Interruption and Turn-Taking QA: Stress barge-in, talk-over and mid-call mind changes that scripted happy-path tests never exercise.
Capacity Planning: Load-test how many concurrent calls an agent stack sustains before latency or quality degrades.
Multilingual and Accent Coverage: Validate performance against non-native speakers and callers who switch languages mid-sentence.
