## Sieve

Sieve began life as a video API company offering endpoints for translation, dubbing, background removal, lipsync, autocrop and transcription. That product line has since been superseded: the company published an announcement titled "Reintroducing Sieve" describing its transition from video APIs to supplying multimodal data at petabyte scale, and the original sievedata.com domain now resolves to sieve.ai.

Today Sieve operates as a data lab for what it calls real-world intelligence. Instead of selling individual API calls, it works with frontier AI companies to design, capture, annotate and deliver high-quality training and evaluation data. Its public offerings include egocentric first-person video of economically valuable work with hand-pose and sensor annotations, custom multi-camera studio recordings, simulated and real-world robotics evaluations, virtual-world capture with synchronised control inputs and camera metadata, and datasets targeting motion, causality and spatial reasoning.

Underneath the data products sits serious infrastructure. Sieve has published engineering work on embedding one billion videos and querying tens of billions of vectors, which is the kind of stack you need to make petabyte-scale audiovisual archives searchable for model training. The practical route in is a conversation rather than a signup: visitors are pointed at "Talk to us" and "Request data" flows, and the company is actively hiring researchers and engineers.

**Pricing & Plans:** No public price list. Sieve is positioned as a custom engagement led by a "Talk to us" / "Request data" contact flow, so commercial terms are scoped per project, data volume and capture complexity. Earlier self-serve API pricing is no longer published.

- **Egocentric data capture:** First-person recordings of economically valuable physical work, paired with hand-pose, motion and synchronised sensor annotations.
- **Studio and custom rig recordings:** Multi-camera video and audio collection with bespoke rigs and controlled environments built to a client's specification.
- **Robotics evaluations:** Both simulated and real-world test suites that measure how well robot policies perform across tasks and conditions.
- **Large-scale media infrastructure:** Petabyte-scale synchronised video and audio datasets, including published engineering work on embedding a billion videos for retrieval.
- **Real-world reasoning datasets:** Datasets and benchmarks targeting motion, causality and spatial relationships for models that must reason about the physical world.

**Strengths:** Deep specialisation in hard-to-collect embodied and egocentric data; In-house research and infrastructure proven at billion-video scale; Offers evaluations alongside datasets, not just raw media; Works directly with frontier labs, which signals high data quality standards

**Limitations:** Pricing is quote-based, so there is no self-serve cost transparency; Most offerings require an engagement rather than instant API signup; Documentation for the older video API suite is no longer reachable at the previous docs domain; Overkill for teams that only need a single simple video-processing endpoint

## ZeroGPT

ZeroGPT is best known as an AI content detector, but the site has expanded into a full writing and verification toolkit. The core AI/GPT detector lets you paste text or upload a file and returns a highlighted analysis showing which sentences look machine-written, with a percentage gauge and an automatically generated PDF report you can use as documentation.

Around that core sit several companion detectors and writers. The AI image detector and AI video detector extend checking beyond text; the plagiarism checker scans against billions of sources; and the AI humanizer and paraphraser rewrite text into a more natural style. A grammar checker, summarizer, translator, dictionary, word counter, citation generator, and AI email helper round out day-to-day writing tasks. The company says its multi-stage DeepAnalyse model is trained on internet text, educational datasets, and proprietary synthetic AI datasets, covers over 35 LLM families, and reports 98.4% detection accuracy with a false positive rate under 1%.

Access is freemium: the main tools work free in the browser, with MAX and EXPERT subscriptions for heavier use and premium features, and a separate API for organizations that need large-scale integration. ZeroGPT also runs on WhatsApp and Telegram through a bot, letting you chat, detect AI text, summarize, paraphrase, translate, and check grammar without leaving the messaging app.

**Pricing & Plans:** Freemium with paid tiers. Core tools such as the AI detector, summarizer, and grammar checker are usable free in the browser, while MAX and EXPERT subscriptions unlock higher limits and premium features, and API access is sold separately for organizations.

- **AI and ChatGPT detection:** Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report.
- **AI image and video detection:** Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals.
- **Plagiarism checking and humanizing:** Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning.
- **Writing and productivity tools:** A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer.
- **API for organizations:** A documented REST API exposes detection, plagiarism, paraphrasing, summarization, grammar, chatbot, and translation endpoints for organizations that need to embed ZeroGPT at scale.

**Strengths:** Free browser access to the core AI detector, summarizer, and grammar checker; Sentence-level highlighting with an overall percentage and exportable PDF reports; Extends beyond text to AI image and video detection, plus plagiarism checking; Broad companion toolkit: humanizer, paraphraser, translator, dictionary, citations, email helper

**Limitations:** AI detectors can produce false positives, so results should be treated as a signal rather than proof; The strongest features sit behind MAX/EXPERT paid tiers and API access is a separate purchase; Character limits apply to the free detection box; No detection tool can guarantee correctness across every model and language
