Where Annotators Struggle,
Copilot Gives You the Edge

Video Evaluation Suite

Frame-By-Frame Temporal Coherence & Action Consistency

Evaluating generative AI video or checking whether a model followed a complex multi-step prompt across 15 seconds is exhausting. NotateAI extracts keyframes, tracks prompt adherence second-by-second, and highlights continuity errors before you submit your evaluation.

Video Eval Copilot • Active Inspection

FPS: 30 • 00:08.4s

Laser Scan • Active Layer #24

Frame 142: Left Hand Morph

Prompt: "Man turns around holding coffee cup" Severity: Minor Defect

Copilot Suggested Rating: 3 / 5 (Noticeable Artifact)

Temporal consistency is maintained until 00:04.2s, where finger anatomy blends into cup handle. Ground truth annotator confirmation required.

Image Critic & Visual Grounding

Spot Micro-Hallucinations, Lighting Clashes & Text Inconsistencies

Top AI labs like Midjourney, Flux, and OpenAI rely on image critics to detect subtle anatomical flaws, reflections that don't match light sources, and unreadable typography. Your copilot evaluates 14 critical visual axes in milliseconds.

Project Guideline Comprehension

Never Fail a Platform Quality Audit Because of Hidden Rules

Every project on major annotation platforms comes with a dense 40-page PDF of instructions full of "Must Haves" and "Instant Fail" edge cases. NotateAI highlights exact evaluation pitfalls for each individual task you receive.

Rubric Inspector • Production AI Project Cheetah 100% Policy Compliant

✓

Rule 4.2: Factuality Verification

Model claims verified against 3 primary sources. No hallucination found.

✓

Rule 7.1: Formatting & Markdown Compliance

Tables and LaTeX math formulas strictly match specified guidelines.

Critical Checkpoint: Instruction Following

Prompt requested 4 bullets; model delivered 5. Recommended penalty: -1 point.

Our Core Creed

AI Provides Deep Evaluation Speed.
Humans are the Ground Truth.

Every leading AI model in the world exists only because thoughtful human annotators sat down, inspected edge cases, and corrected mistakes.

We built NotateAI to empower human annotators, not replace them. Our copilot gives you superintelligence so you never miss a guideline nuance, get penalized by a reviewer, or spend an unpaid hour reading contradictory project rubrics.

Authentic Reviewer Evaluation

1. Overall Preference: Candidate B (Decisively Preferred)

Candidate B (Model Beta) >> Candidate A (Model Alpha) [Score: 5/5 vs 1/5]. Candidate B is an authentic 1908 ground-truth archival document. Candidate A is heavily synthetic and completely fails factual instruction adherence and text rendering.

2. Visual Quality: Model B (5/5) vs Model A (2/5)

Candidate B demonstrates authentic 1908 gelatin silver print exposure, natural optical depth of field, real directional daylight, and genuine heavy wool textile drape. Candidate A exhibits synthetic diffusion smoothing, flat artificial illumination, and uncanny facial symmetry.

3. Artifacts: Severe Hallucinations in Model A

Candidate A suffers from catastrophic generative flaws: every single placard contains unintelligible pseudo-script glyphs ("VOIL HOI...", "SUURILOG..."), finger joints holding flagpoles are fused/melted, and the left umbrella handle dissolves into coat fabric. Candidate B has zero generative artifacts (only natural period camera plate edge flare and paper board wear).

4. Reasoning: Audit-Ready Rationale

Candidate B complies 100% with the historical prompt and text legibility rubrics. Archival event announcements ('VOTES FOR WOMEN MEETING', 'CAXTON HALL ESSEX ST. STRAND') and named historical suffragette leaders (Mrs. Despard, Irene Miller, Edith How Martyn, Miss Neilans) are fully legible. Candidate A completely hallucinates fake text, making Candidate B decisively superior.

1. Overall Preference: Candidate B (Decisively Preferred)

Candidate B (Model Beta) >> Candidate A (Model Alpha) [Score: 5/5 vs 2/5]. Candidate B is an authentic documentary photograph capturing realistic human interactions and true optical physics. Candidate A is AI-generated with severe skeletal and spatial errors.

2. Visual Quality: Model B (5/5) vs Model A (2/5)

Candidate B demonstrates authentic documentary indoor lighting, natural lens depth of field, and tangible fabric textures (knitted sweater, denim, plaid shirt). Candidate A has oversaturated colors, flat artificial lighting, and plastic airbrushed skin lacking pores.

3. Artifacts: Critical Anatomical Defect in Model A

Candidate A contains a critical anatomical defect: the girl on the far left has an impossibly elongated right arm extending across the torso of the second child to touch the table, alongside waxy facial textures and merged finger joints on paintbrushes. Candidate B has zero generative flaws (natural lens refraction through eyeglasses and authentic skin pores).

4. Reasoning: Audit-Ready Rationale

Candidate B complies 100% with the prompt and real-world physics. Multi-figure spatial relationships and skeletal meshes are completely natural and plausible. Candidate A violates fundamental human anatomy rubrics, making Candidate B decisively superior.

★★★★★

"Before NotateAI, I lived in fear of sudden platform quality audits. The video evaluation copilot catches the tiny frame glitches that human eyes miss when you're 4 hours into a shift. My quality score has been 100% for 3 straight months!"

Sophia M.

Senior Video Annotator

★★★★★

"The 40-page rubric digest is a superpower. Instead of searching through a huge Google Doc every time I grade a prompt on client projects, the copilot summarizes the specific constraints for the exact task in front of me."

Marcus T.

Multimodal Specialist

★★★★★

"I went from $20/hr to being placed in the $48/hr expert tier because my review justifications were cited as 'model benchmarks' by the project leads. NotateAI paid for itself within my first 30 minutes."

Questions & Answers

Frequently Asked Questions

Everything you need to know about using NotateAI safely and effectively.

Yes. NotateAI operates as an independent review assistant and verification copilot, functioning much like a grammar checker, calculation verifier, or style guide. We help annotators make sense of every task, provide perspectives and dimensions they may be missing, and ensure the researchers' goals for each evaluation are fully met. It does not automate submissions or interact with platform APIs; you remain 100% in control as the human author, reviewer, and final decision-maker.
