Context

Why this matters in 2026

Google's Helpful Content Update has reshaped what ranks. Pure AI-generated content — long-form, on-topic, technically optimized, indistinguishable from competent human writing — has lost 20-40% of its rankings year-over-year on most agency-managed sites. The penalty isn't direct AI detection. It's an indirect signal: Google's quality raters consistently flag AI-heavy content as low E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness), and the algorithm picks up on that.

The result is that every agency now has a pre-publish AI audit step in their content workflow. The question is which tool you use. Originality.ai's API tier is $179/mo Enterprise — fine for agencies pushing 1.5M words/month, expensive overhead for everyone else. GPTZero's API is a paid add-on. Copyleaks' API requires a $74.99/mo Pro subscription. Winston AI's API is on the Advanced tier ($16/mo annual).

TextSight bundles detection + humanizer + API access into one product at one tier. Business at $29.99/mo annual includes 10,000 API calls per month, unlimited scans, the same humanizer your writers can use to fix flagged content, and white-label-ready PDF reports for client deliverables. For agencies processing under 1.5M words per month, this is typically 4–6× cheaper than the equivalent Originality stack.

And the humanizer matters. When a draft scores 70% AI, you have two choices: send it back to the writer for a manual rewrite (slow, expensive) or run it through a humanizer (fast). Other detection tools force you to a separate humanizer subscription. TextSight has both built in, in one workflow.

The Problem

The 2026 agency problem

Google is hammering AI-heavy content

The Helpful Content Update prioritizes content with author expertise and specific viewpoints. Pure AI tends to lack both. Agencies that ship AI-assisted content are seeing 20-40% ranking drops year-over-year.

Clients audit every deliverable now

After one too many burned brands, clients run agency content through Originality.ai or GPTZero before paying. A 78% AI score = invoice dispute, sometimes contract termination.

You're processing 50-500 articles/week

Manual scanning isn't viable at agency scale. You need API access, bulk processing, and a way to get the score into your existing CMS or workflow.

Originality's API tier is $179/mo Enterprise

For an agency processing fewer than 1.5M words/month, Originality's pricing forces you into Enterprise. Most mid-size agencies need a $20-50/mo API tier — which TextSight has.

White-label reports are an upsell, not a feature

Most detection tools don't support white-label PDF exports without an Enterprise contract. Agencies that brand reports for clients have to build their own export pipeline on top of an API.

The Fix

How TextSight fits an agency workflow

1

REST API in Business tier ($29.99/mo)

API access at the Business tier — not Enterprise. 10,000 calls/month. Integrate into your CMS (WordPress, Webflow, Sanity), publishing pipeline (Make, Zapier), or QA dashboard.

2

Bulk URL scan + file upload

Pro+ tiers support URL scanning (paste a published-article URL, get a score) and file upload (.docx, .pdf). Both useful for incoming client briefs and outgoing deliverables.

3

Humanizer for content that fails detection

When a draft scores high on AI, the same tool offers a one-click humanizer. Other detection tools force a tab-switch to a separate humanizer (Undetectable, $5-31/mo extra). TextSight bundles both.

4

Scan history exportable as PDF

Every scan is saved. Export per-article PDF reports for client deliverables. Includes timestamp, score, and sentence-level breakdown — useful as proof-of-work.

In Practice

A typical agency content workflow

  1. 1 Client briefs land in your project management tool with target keywords + word counts.
  2. 2 Writers (in-house or contract) draft articles. Articles flow into your QA queue.
  3. 3 API call: each article hits TextSight's scan endpoint. Score returned in 5-10s.
  4. 4 Anything above 60% AI gets routed to the humanizer endpoint (or flagged for human revision).
  5. 5 Re-scan after humanizer. Final score attached as metadata in your CMS.
  6. 6 PDF report generated per article, attached to client deliverable. Invoice goes out clean.

FAQ

Common agency questions

Does Google actually penalize AI content?

Indirectly. Google's Helpful Content Update (2022, refined in 2024-2025) prioritizes content demonstrating author expertise, specific viewpoints, and original research. Pure AI-generated content typically scores low on these signals. The penalty is correlation, not direct detection — but the result is the same: AI-heavy content tends to lose rankings.

Does TextSight have an API I can integrate?

Yes. The Business tier includes 10,000 REST API calls/month. The endpoint accepts text or URL input and returns a JSON response with the AI score, sentence-level breakdown, and humanization recommendations. See api.textsight.ai/docs for details.

White-label reports?

PDF export is included in all paid tiers with TextSight branding minimal. For full white-label (your agency's logo, custom domain on share links), Enterprise tier or contact sales for agency licensing.

Reseller pricing?

Yes, agency licensing is available. Contact sales for volume pricing if you're processing 1,000+ articles/month or onboarding multiple clients to white-labeled detection.

Bulk URL scan for indexed articles?

Yes, Pro+ tiers support URL scanning. Paste any public URL, TextSight fetches and scans the content. Useful for auditing already-published client work.

How does this compare to Originality.ai for agency work?

TextSight bundles a humanizer (Originality has none) and offers API access at $29.99/mo Business (Originality's API is Enterprise-only at $179/mo). For agencies processing under 1.5M words/month, TextSight is typically 4-6× cheaper.
