Document import warnings surfaced

TXT, Markdown, DOCX, and PDF imports now keep source kind, filename, and parser warnings visible in writing and detector workflows.

May 2026release

Detector response normalized

Detector-style scans now return review estimates, source context, status, and writing-signal metadata through the same public API shape.

May 2026release

Writing tools added

Launched usable AI rewriter, paraphrase, detector, citation generator, and bibliography generator pages backed by the shared writing workflow.

May 2026release

Homepage workbench

Shipped the TurnitPass humanizer homepage with document input, processing language selection, rewrite action, and side-by-side result review.

May 2026release

Workspace usage overview added

Added workspace summary surfaces for word balance, subscription state, API keys, and recent usage so billing and developer access stay together.

May 2026release

Integrated plan limits

Checkout, billing portal, and plan-limit code paths are in place while production settings remain externally configurable.

April 2026release

Private API key storage

API keys are shown once, stored as secure hashes, and can be revoked without changing Google account access.

Release policy

The changelog follows the same product boundary as the API platform: public notes cover endpoint behavior, billing surfaces, document parsing, and visible workflow changes. Internal implementation details stay unpublished unless they affect public behavior.

Versioning
v1 routes stay stableBreaking API changes should ship under a new versioned route. Additive response fields may appear on existing v1 endpoints.
Release notes
Focused on behaviorPublic notes describe behavior changes and compatibility impact.
Billing
Billing keys remain configurableBilling, portal access, and plan limits remain configurable without exposing private setup details.
Documents
Parser changes are notedDocument import behavior for TXT, Markdown, DOCX, and PDF should be visible when it affects extracted text or warnings.

API compatibility notes

Existing API keys
Remain valid unless revokedKeys are stored as hashes and can keep calling v1 endpoints until a user revokes them or usage rules change.
Response fields
Additive by defaultClients should ignore unknown fields. Removing or renaming response fields requires a versioned change.
Word limits
Documented in referenceTransform endpoint and detection word limits are reflected in API reference and smoke coverage.

FAQ

What do changelog entries cover?

Behavior changes, endpoint impact, and compatibility expectations, with examples where they help.

How should API clients handle new response fields?

Treat unknown fields as additive metadata. Clients should parse the fields they need and ignore additional keys unless the API reference says otherwise.

Where do billing configuration changes appear?

Billing behavior is noted here when checkout, portal, or plan-limit logic changes. Production credentials are configured securely outside the codebase.
