Why Writerflow

Most “content approval” tools handle pixels. We handle paragraphs.

Filestage, Ziflow, and PageProof are built for design files and video. Planable is built for social posts. Writerflow anchors every approval to the version it approved — built around how agencies actually run client content.

Built for written content

Articles, newsletters, briefs, white papers, ad copy. The proofing tools were never designed for the way writers and editors actually work.

Made for the agency model

Multiple clients, external stakeholders, internal review before client review. Built around how agencies actually run, not generic project management.

Reviewer access is always free

Clients and external reviewers never pay, never sign up, never log in. You only pay for the people on your team building and shipping the work.

Audit trail by default

Every comment, approval, reminder, and deadline event is timestamped automatically. Proof of who said yes — without an enterprise contract.

Key Capabilities

Everything an agency needs to run content approval across every client.

Inline comments

Reviewers leave comments tied to specific paragraphs — not vague “tighten the third section” emails.

Right reviewers, right order

Editorial → legal → client review in order. Each one signs off before the next sees the work.

Review deadlines

Per-reviewer due dates, automated reminders, and silence-as-approval so unresponsive reviewers don't hold up your pipeline.

Magic links

Time-limited links let external reviewers approve without ever creating an account. Free, frictionless, revocable.

Version control

Every revision is tracked. Compare versions side by side. Approval is locked to a specific version — no drift after sign-off.

Audit trail

Every view, comment, approval, reminder, and deadline event is logged with timestamps. Exportable when you need to prove who said yes.

End the “is this approved?” loop

Draft, In Review, Approved, Changes Requested. Binary decisions kill ambiguous email replies — the answer is always visible.

Bundled reviewer notifications

One clear email per reviewer with the document, deadline, and approve link. Bundled by default so reviewers never get spammed into ignoring you.

Content calendar

Every piece of content, every approval state, every deadline — all clients on one calendar.
