Scribendi

Scribendi has operated as an online editing service since 1997, serving 336,000+ clients in 150+ countries and editing 3.3 billion+ words. For indie authors, it offers a reliable alternative to searching for individual freelancers: upload a manuscript, select a turnaround time, and receive a professionally edited file with tracked changes and editor notes. The company holds ISO 9001:2015 certification (FS 549441) — a formal quality management standard rarely seen in the editing services market.

What You Get#

• Book proofreading: Line-by-line correction of spelling, grammar, typos, and formatting inconsistencies. Delivered with tracked changes and personalized proofreader notes summarizing completed work.
• Book editing (developmental + line + copy): A combined service addressing sentence-level clarity, word choice, and mechanical correctness. Scribendi now also advertises developmental work inside this service — feedback on plot, character development, and overall narrative flow — alongside style, tone, point of view, and sentence structure suggestions.
• Book critique: A 1–2 page written assessment covering plot, dialogue, characterization, structure, coherence, and organization (fiction) or argument support and flow (nonfiction), plus salability. Sold separately from line-level editing.
• Ebook editing, proofreading, and formatting: Formatting is done by hand rather than by software, and delivers a Smashwords-ready Word file plus a filtered HTML file and Word document meeting Amazon KDP requirements, with a clickable table of contents.
• Query package: Query letter editing and synopsis creation for authors pursuing traditional publishing alongside self-publishing routes. Also sold bundled with book proofreading.
• Free sample edit: Submit a portion of your manuscript before committing to the full job to evaluate editor quality firsthand.

Who It's For#

• Authors with urgent timelines: Rush delivery is available in as little as 4 hours for manuscripts under 1,500 words — useful for short stories, excerpts, or contest submissions with hard deadlines.
• Nonfiction and hybrid-publishing authors: Scribendi handles academic, business, and general nonfiction alongside genre fiction, making it workable for authors who publish across multiple formats or need credentials-specific editing.
• Authors who value institutional accountability: ISO certification, a BBB A+ rating (accredited since 2005), and nearly three decades of operation mean the company has documented quality processes rather than variable freelancer arrangements.

Turnaround ladder (book editing): 4 hours up to 1,500 words; 24 hours up to 10,000; 72 hours up to 40,000; 1 week up to 65,000; 2 weeks for 65,001–100,000; 3 weeks for 100,001–150,000; 4 weeks for 150,001–250,000; 5 weeks for 250,001–450,000. A typical 70,000–90,000-word novel therefore lands in the 2-week tier, not the advertised 1-week one.

Pricing: No rate card is published — every quote comes from an instant calculator keyed to word count and turnaround, so the figures below are third-party samples rather than vendor-stated rates. Editor World priced a 45,000-word manuscript at $2,147 on the one-week turnaround in July 2026, about $0.048 per word. On that basis a 70,000-word novel runs roughly $3,000–$3,500. Proofreading is cheaper than editing (reported near $0.035/word at one week) and rush tiers cost sharply more — Scribendi's own guidance illustrates a project quadrupling in price when the deadline tightens, with the fastest book tiers reported around $0.083/word. Run your own quote before budgeting. All orders are priced per project — no subscription.

Strengths#

• Industry-leading turnaround speed: 4-hour edits for short documents and 1-week delivery for manuscripts up to 65,000 words. Few comparable services match this consistently.
• ISO 9001:2015 certification: Requires documented quality management processes and regular audits — one of the few editing services to hold this credential.
• Published AI policy: Scribendi states every document is edited by a person, and discloses exactly two AI uses — its own predictive (non-generative) Scribendi AI, which flags grammar, punctuation, spelling, and consistency issues but cannot change a document on its own, and third-party generative tools used under commercial agreements for quality checking and internal workflow, with client content excluded from provider model training. Most human editing services publish nothing this specific.
• 581 Trustpilot reviews: Long-term clients frequently cite consistent quality and editors returning work ahead of schedule. Scribendi advertises a 4.7/5 average on its own site; that figure is self-reported and aggregates multiple platforms, so treat it separately from the Trustpilot profile.

Limitations#

• No direct editor communication: Editors are anonymous and assigned by subject expertise. You cannot correspond with the person editing your manuscript, ask clarifying questions, or discuss editorial direction before work begins.
• Cannot re-hire a preferred editor: If you receive excellent work, there is no mechanism to request the same editor for future projects — each order goes into the general queue.
• Thin standalone structural feedback: The Book Critique deliverable is 1–2 pages. Authors who need a full developmental edit letter on a novel will find that far shorter than what a dedicated developmental editor produces.
• Higher cost than marketplace alternatives: At roughly $0.048 per word, a 70,000-word novel costs around $3,350 for editing — notably more than Reedsy's stated average copyediting rate (~$0.027/word) for comparable work.
• Scope mismatch and inconsistency reported: Reviewers and third-party roundups describe orders coming back as a heavier or lighter edit than requested, and edits that addressed surface-level corrections while leaving deeper issues intact. The free sample edit is the cheapest way to test this before committing.

Alternatives#

Reedsy matches authors with vetted freelance editors at comparable or lower per-word rates, with direct editor communication and the ability to choose your editor before committing. ProWritingAid offers AI-based self-editing at a fraction of the cost for authors who want to reduce mechanical issues before engaging a human editor.
