Writesonic lists self-serve plans from $99 a month with a 7-day trial and no card, while BrightEdge prices by custom proposal and offers no public plans or trial. Writesonic fits teams that want to test AI visibility tracking and article writing on their own, and BrightEdge fits large teams that already buy enterprise SEO through sales. DeepSmith is a strong alternative on the same question, with published prices from $99 a month, a 7-day trial, and a fixed monthly allowance of publish-ready articles on every plan.
Writesonic vs BrightEdge is mostly a question about how you want to buy. With Writesonic you can read the tiers, start a trial and see what the entry plan covers before anyone calls you. With BrightEdge the price comes from a proposal, and the product behind it is a full enterprise SEO suite with an AI search layer added on. Both track how AI engines mention and cite your brand, so the useful difference is how much you can learn about cost and fit before a sales call. DeepSmith sits on the self-serve side of that split and puts writing in the same plan price as tracking.
Writesonic vs BrightEdge: the short answer
- Choose DeepSmith if you want to see the price, start a 7-day trial, and get tracking plus a fixed monthly allowance of 20 to 90 publish-ready articles from $99 a month, with no long-term contract.
- Choose Writesonic if you want self-serve tiers at $99, $249 or $499 a month on monthly billing, a no-card trial, and tracking across three engines with article writing included.
- Choose BrightEdge if you are a large team that already runs enterprise SEO and you are ready to work from a custom proposal with no public plans or trial.

Pricing and features as of September 2026, from each vendor's site and public reviews.
Writesonic
Writesonic started in 2021 as an AI writing tool, is backed by Y Combinator, and now calls itself an AI search growth engine. It tracks prompts daily and reports brand mentions, citations, share of voice and, on Growth and Enterprise, sentiment. It also adds AI crawler analytics, ads tracking, an Action Center that ranks fixes, and an Article Writer that Writesonic says produces long articles with citations, FAQs and internal links. It is built for marketing, SEO and content teams, and for agencies that want tracking and execution in one tool.
The standout is the packaging. The pricing page lists prompts, daily answers, articles, audits, users and projects for every tier, and the 7-day trial needs no card. The limit is where the self-serve plans stop. Starter, Basic and Growth track ChatGPT, Gemini and Google AI Overviews, and the full ten-engine set, most of the Action Center, alerts and page tracking sit on custom Enterprise plans. On reviews, G2 shows 4.7/5 from 2,133 reviews and Capterra 4.8/5 from 2,102, checked in September 2026, but most of those reviews are about the older writing product. Those reviews often mention pricing and credit limits, and the few reviewers of the AI visibility product mention a learning curve.
BrightEdge
BrightEdge was founded in 2007 and is based in San Mateo. It sells an enterprise SEO platform covering keyword research, rank tracking, site audits, recommendations and reporting, and its AI layer includes AI Catalyst, AI Hyper Cube, AI Agent Insights and Agent Edge. AI Catalyst tracks mentions, citations and sentiment across ChatGPT, Perplexity, Google AI Overviews, Google AI Mode and Gemini, and it can test answers by persona. It is built for large in-house SEO, content and web teams, and for the agencies that serve them.
The standout is breadth, since classic search data and AI search visibility sit on the same data, and the platform adds a REST API and a read-only MCP server. The limit that matters here is that nothing about price is public. The pricing page is a contact form and a phone number, no tiers or limits are published, and there is no trial. BrightEdge's own pages also don't say how often AI answers are sampled or how they are collected. G2 shows 4.4/5 from 882 reviews and Capterra 4.1/5 from 45, checked in September 2026. Reviewers like the depth of the keyword and ranking data, and they raise opaque pricing, a steep learning curve and slow performance.
DeepSmith: the alternative with published prices and publish-ready articles
Buyers who are pricing this category run into a different gap with each vendor. Writesonic publishes tiers, though much of its execution sits on Enterprise and its self-serve plans cap out at three engines. BrightEdge shows no price, no plan limits and no trial, and its content tools stop at briefs and drafts. Both do real work, and BrightEdge's AI layer sits on a deep base of search data. DeepSmith is built so that tracking and production share one plan and one visible price.
DeepSmith is an AI search analytics and content production platform in one. AI Visibility tracks mention rate, citation rate and share of voice, shows which of your pages AI actually cites, and lists who wins citations for your prompts. Content Map compares your site with competitor sites topic by topic, and Opportunity Agents turn that data into content ideas that each carry the data point behind them.
From there the Writer turns a planned idea into a researched, linked article with a cover image and metadata, so the output is publish-ready and not a draft to rescue. Autowrite does it on a schedule with no one in the app, and Produced Content publishes to WordPress, Webflow, Strapi, Sanity or Contentful, or to your own webhooks. Deep IQ stores your brand voice, products and personas once, so every article starts from your own context.
The price is on the page. Pro is $99 a month ($80 billed annually) with 20 articles, 50 tracked prompts, five seats and ChatGPT tracking. Grow is $199 ($160 annually) with 40 articles, 100 prompts and seven seats, and it adds Perplexity. Scale is $399 ($299 annually) with 90 articles, 200 prompts and ten seats, and it adds Gemini. Enterprise is custom and covers all ten engines. A 7-day free trial is offered, there are no long-term contracts, and the article allowance is a fixed number each month, not credits. DeepSmith is SOC 2, GDPR and ISO certified and is rated 4.8/5 on G2.
Pricing and value
Writesonic wins this part of the pair, because it publishes a price list and BrightEdge publishes nothing. Writesonic vs BrightEdge pricing is really a comparison of a set of tiers against a proposal, so the detail below is mostly about Writesonic.
The Writesonic pricing page leads with annual rates of $79, $199 and $399 a month for Starter, Basic and Growth. The monthly figures are $99 for Starter, which a Writesonic comparison page states outright, and $249 and $499 for Basic and Growth, which follow from the annual-savings badges on the pricing page. I'd confirm those two with Writesonic before putting them in a budget. Starter gives you 50 prompts, one user, 15 articles a month and 10 site audits. Basic moves to 100 prompts, two users and 25 articles, and Growth to 200 prompts, three users and 50 articles, with a limited Action Center. Extra users cost $50 a month on Basic and Growth, and Growth can add 20 articles for $100 a month. Enterprise is custom.
BrightEdge gives you a contact form and a phone number. The product pages offer a demo and a custom proposal, and the pricing page doesn't say which AI modules a subscription includes. Third-party research reports that BrightEdge states AI Catalyst is included in its SEO Platform subscriptions, but the pricing page doesn't confirm that. One third-party pricing site gives a starting estimate, which is not a BrightEdge quote, so I wouldn't budget from it. A dated written quote that names the modules, engines, prompts, users, sites and renewal terms is the safest thing to ask for.
What DeepSmith does: DeepSmith publishes its prices on monthly and annual billing, from $99 to $399 a month before Enterprise. Each plan includes a fixed monthly allowance of publish-ready articles, 20, 40 or 90, so you can work out a cost per article without a quote.
Free trial and evaluation before sales
Writesonic wins here, since BrightEdge offers no trial. Writesonic gives a 7-day trial with no card on Starter, Basic and Growth, and its Enterprise and agency plans are demo-led. That means you can run your own prompts against the entry plans and see the three tracked engines before you spend anything.
BrightEdge sends every product call to action to a demo request. There is no signup, free plan or trial, though its agency page mentions trial accounts set up for agencies that are pitching clients. What you can check ahead of a call is the public side, which is the feature pages, the review sites and the G2 rating of 4.4/5. The questions to bring to the call are the ones the public pages leave open, namely how often AI answers are sampled, how each engine is collected, which countries and languages are covered, how long answers are kept, and whether AI Hyper Cube, AI Agent Insights and Agent Edge are included or sold separately.
What DeepSmith does: DeepSmith offers a 7-day free trial, and onboarding takes you from signup to a working workspace in minutes. Your brand brief, competitors, starter tracking prompts and first batch of ideas are filled in before you pay, so you see real data and real drafts first.
Engine coverage
Writesonic wins on published coverage, with the caveat that its widest coverage is on Enterprise only. Its self-serve plans track ChatGPT, Gemini and Google AI Overviews. Enterprise adds Google AI Mode, Perplexity, Claude, Microsoft Copilot, Grok, Meta AI and DeepSeek for ten in total, and the agency plans cover nine or ten.
BrightEdge names five engines in AI Catalyst, which are ChatGPT, Perplexity, Google AI Overviews, Google AI Mode and Gemini, along with "other AI platforms" that it doesn't list. It doesn't say which plans get which engines. Claude shows up only as an AI agent that visits your site, not as an engine whose answers are tracked.
What DeepSmith does: DeepSmith tracks ten engines, ChatGPT, Gemini, Perplexity, Claude, Google AI Overviews, Google AI Mode, Grok, Meta AI, Microsoft Copilot and DeepSeek. Coverage rises by plan, with ChatGPT on Pro, Perplexity added on Grow, Gemini added on Scale, and all ten on Enterprise, so you can read what you get at each price.
Tracking depth and data method
Writesonic documents more of its tracking, and BrightEdge brings more classic search context. Writesonic tracks prompts daily on every plan, says it collects answers by crawling the AI platforms' web interfaces like a real user, and adds query fan-outs, an ads tracker and AI crawler analytics. Shopping tracking is Enterprise only on its brand plans. Its only in-answer position metric is a shopping rank, and the self-serve plans cover one market, meaning one language and country pair.
BrightEdge separates Mentions Presence from Citations Presence, rates sentiment as positive, neutral or negative with reasoning, and can test an answer as a practitioner or a decision maker. AI Hyper Cube shows every AI answer that cites a given URL, built on a Data Cube X core that claims four billion data points and ten years of history. The gap is method. Sampling frequency, collection approach, locations and answer retention for AI Catalyst are not published, so the depth is real but you can't check how it is measured until you ask.
From insight to action
Writesonic wins this one, because BrightEdge's content output stops short of full articles. Writesonic's Action Center ranks on-page, off-page and technical fixes, with a limited version on Growth at five on-page and five off-page actions a month and the full version on Enterprise. Its Article Writer produces 15, 25 or 50 articles a month on Starter, Basic and Growth, and it exports to WordPress on every plan, with Sanity, Contentful, Webflow and Ghost also listed. Brand kits and uploaded data are there to ground the writing.
BrightEdge turns citation gaps into briefs, checks drafts against them in Content Advisor, and suggests titles and descriptions through Copilot. Its Publishing Agent pushes approved title tag, meta title and H1 changes into WordPress, Drupal or another major CMS, and a person confirms every change. No full article generation or stored brand context is described.
What DeepSmith does: DeepSmith runs the whole loop on one platform. Tracking shows where you are missing, Opportunity Agents return ideas with the evidence attached, and the Writer produces the finished article with its internal and external links, cover image and SEO metadata built in. Autowrite can schedule that hands-off, and Produced Content publishes it to your CMS, so the gap you found in AI answers turns into a live page without a separate writing tool.
Which should you choose
If you are deciding between Writesonic or BrightEdge, the choice mostly follows how much you want to see before a sales call.
- DeepSmith: the broadest fit for a marketing lead who wants to track AI visibility and publish the content that closes the gaps from one plan, with prices on the page, a 7-day trial and a fixed monthly article allowance.
- Writesonic: a small or mid-size team that wants self-serve tiers, a no-card trial and article writing, and is fine with three engines until it moves to Enterprise.
- BrightEdge: a large in-house SEO team that already runs enterprise SEO, wants AI search layered onto the same data, and has time for a proposal process.
