The short answer: every sales team writes: proposals, follow-up sequences, case studies, cold outreach and internal briefs. AI writing tools speed up the drafting, but the output still needs a quality check before it reaches a prospect's inbox. The eight tools below cover that check from different angles: an AI detector for machine-sounding copy (GetSolved), an email coach (Lavender), conversation intelligence for calls (Gong), team style and tone (Grammarly), readability (Hemingway), plagiarism and AI detection at scale (Copyleaks), brand voice rules (Jasper) and in-depth style reports (ProWritingAid).
Valley is an AI outbound platform that finds the people most likely to buy from you - from live buying signals, natural-language search, or your own lists - qualifies them against your ICP, researches each one, and sends personalized messages across email and LinkedIn that get 15-45% reply rates, against a category average of about 2%.
TL;DR
Check whether copy reads as machine-written: GetSolved, free with no sign-up, with sentence-level feedback.
Score cold emails before you send: Lavender's email coach.
Learn from calls, not just emails: Gong.
One voice across the team: Grammarly's tone profiles and style guides.
Shorter, clearer sentences: Hemingway's free readability checker.
Most teams combine two or three: an AI detector, a readability editor and a grammar or style tool.

Give your sales team
an unfair advantage.
1. GetSolved AI Detector
Sales teams that use AI to generate pitches, case studies or outreach sequences need a fast way to check that the output still sounds human. Prospects are increasingly sceptical of AI-written content, and copy that repeats the same robotic structure as every other pitch loses credibility quickly.
GetSolved analyses any text and returns a percentage score for how likely it is to read as machine-written. This AI detector gives sentence-level feedback, so the team can see exactly which phrases need rewriting instead of guessing where the problem is. The basic check is free with no sign-up: paste the text and read the results. Paid plans add Pro features for teams that audit content often.
2. Lavender
Lavender is an email coach for sales teams. It installs in Chrome, connects to your email provider, and scores each message before you send it, with a score of 90 or above as its target. It learns from your past emails to see what works for you and your team.
Feature | What it does |
|---|---|
Email score | Scores each email for readability, tone and likely response, with fixes listed first |
Tone | Assesses the tone of the message before it goes out |
Personalization assistant | Pulls prospect data into the inbox and suggests ways to tailor the email |
Coaching dashboard | Shows managers what is working across the team and who needs help |
Reps who write many sales emails a day get coaching without leaving the inbox, and managers can spot patterns across the team and train on the weak areas.
3. Gong
Gong records and transcribes sales calls, meetings and emails, then uses AI to find key topics, objections, competitor mentions and buying signals in the conversations. Sales leaders use these patterns to see what buyers actually raise on calls and to build coaching and playbooks around it, rather than around assumptions.
Pricing is not published on its site; trials are arranged with its sales team, and it typically serves mid-market and enterprise teams.
4. Grammarly for teams
Most people know Grammarly for catching errors. Its team plans go further, with brand tone profiles, company style guides and team analytics. Three reasons sales teams use it:
One voice across every rep. A tone profile built from the company's voice guides suggestions, so a junior SDR and a senior AE write in the same style.
A shared style guide. Upload the company style guide and add new terms as they come up.
Team dashboards and admin controls. Dashboards track the team's strengths and areas to improve, and admins assign roles and permissions.
Grammarly works across web browsers, desktop apps and email clients, with one subscription billed centrally for the team.
5. Hemingway Editor
Hemingway shows a readability grade for any text and highlights hard-to-read sentences in yellow and very hard ones in red. It also flags passive voice and adverbs.
Sales writing that reads at a high grade level loses busy executives. Hemingway targets a 9th-grade level by default and pushes writers towards shorter sentences and plainer words. Paste a proposal into the free online checker and it highlights every sentence that could confuse or bore a prospect. The paid Hemingway Editor Plus adds one-click AI fixes.
When it is most useful: reviewing outbound sequences and LinkedIn messages before they go out. Anything a prospect will skim in under thirty seconds deserves a Hemingway pass.
6. Copyleaks
Copyleaks checks text for plagiarism and AI-generated content and returns a report on originality. Key features:
Plagiarism checking in more than 100 languages, and AI detection in 30+
An API with official SDKs, for automated checks inside existing workflows
LMS integrations, such as Canvas, Moodle and Blackboard, for organisations with training programs
B2B sales teams that publish whitepapers, thought leadership and partner-facing material can use Copyleaks as a verification step before release.
7. Jasper
Jasper is an AI content platform for marketing teams. Its Jasper IQ layer holds the brand voice, visual guidelines and style guide, so admins set the rules once and every draft follows them, with separate voices possible for different audiences, sub-brands or regions. A brand compliance diagnostic scans a company's website and public content for how consistently it follows those rules.
This suits sales and marketing teams working on the same campaign copy: a rep's email and the campaign messaging draw on the same voice rules. A free trial is available. Worth knowing: if the team already works in another writing stack, Jasper's value depends on moving drafting into it.
8. ProWritingAid
ProWritingAid goes beyond a basic grammar check with reports on style, sentence length, transitions and repetition.
Report | What it checks |
|---|---|
Style | Readability, clarity and writing style |
Sentence length | The mix of short, medium and long sentences |
Transitions | Where transitions could improve the flow between ideas |
All repeats and echoes | Repeated words and phrases, including repeats close together |
These reports suit sales teams that write long-form material such as case studies, product comparisons or annual reviews. It works in Google Docs and Microsoft Office and has a desktop editor, and its Premium plans include a one-time lifetime option alongside monthly and yearly billing.
Whichever tools check the text, the reply still depends on who gets the message and why. For outreach specifically, see how to stop sounding like AI in outreach.
Give your sales team
an unfair advantage.
No single tool handles every part of sales communication and text quality. Most teams combine two or three: typically an AI detection tool, a readability editor and a grammar or style platform.
Prospects ignoring your outreach? Start with email scoring and readability (Lavender, Hemingway).
Content sounding generic or machine-written? Add an AI detection layer (GetSolved, Copyleaks).
Reps writing in conflicting styles? A tone profile and style guide tool (Grammarly, Jasper).
The best stack is the one the team uses every day. Choose tools that fit existing workflows without adding friction, and the quality of every written touchpoint improves. For the message itself, the research behind it matters as much as the polish: see what personalization does to reply rates and cold email templates for B2B sales.

FAQ
What is an AI text analysis tool for sales? Software that checks sales writing before it goes out: whether it reads as machine-written, how readable it is, whether it matches the brand's tone, and whether it repeats or copies other text. Each tool here covers a different part of that check.
Can an AI detector prove that copy was written by AI? No. Detectors such as GetSolved and Copyleaks return a likelihood score and point to the sentences that read as machine-written. Treat the score as a prompt to rewrite those parts, not as proof.
Is there a free AI detector for sales copy? Yes. GetSolved's basic AI check is free with no sign-up, and Hemingway's online readability checker is free with no word limit.
Which tool is best for cold email quality? Lavender, because it scores each email inside the inbox before sending and shows managers what works across the team.
Do sales teams need more than one writing tool? Usually. Most combine an AI detector, a readability editor and a grammar or style tool, because each catches a different problem.
How do you make AI-written outreach sound human? Research the prospect first, write about their situation in plain words, and cut the phrases every template uses. A detector shows where the copy still reads as generated.
