It solves the common challenge of “Does this read well?” by giving you a second-pair-of-eyes instantly. For anyone who communicates regularly and wants to ensure their writing hits the mark, Co-Sign offers convenient, AI-driven support.

Who is Using?

Co-Sign is ideal for professionals (marketers, consultants, managers) who write frequently, small business owners drafting client communications, content creators polishing posts or scripts, and anyone who wants their writing to make a strong impression without hiring a full-time editor.

Pricing

Typically offered on a freemium model: basic feedback is free or low-cost, with optional premium tiers unlocking deeper analyses, advanced suggestions or team-collaboration features.

What Makes It Unique?

What sets Co-Sign apart is its focus on endorsement and audience-fit: rather than just correcting grammar, it evaluates whether your writing “works” for your target reader and purpose. Its feedback is framed as supportive “co-signing” your message so you send with confidence.
