The writing tool market is undergoing a seismic shift. The introduction of LLMs like GPT-4 and Claude has made it incredibly easy to build a 'writing assistant,' leading to a massive flood of AI writing wrappers. For an indie hacker in 2025, just having an AI that writes blog posts is no longer a viable business model. To stand out, you must build hyper-specific tools tailored to distinct workflows (like technical documentation, specific copywriting formulas, or novel outlining) and, crucially, you must build in public. When you build your writing tool in public on BuildInProcess, your development log acts as the ultimate proof of concept. You share the raw, unedited outputs of your AI versus the polished final drafts, your struggles to reduce hallucination rates, and your pricing experiments. Because your audience consists of writers, marketers, and other creators, they appreciate the craft of storytelling. By transparently sharing your journey, you don't just acquire users; you acquire a dedicated community of wordsmiths who will rigorously test your tool, provide essential feedback on tone and formatting, and champion your product to their own audiences.
If you are building a tool that writes better, your public updates must be impeccably written. Using your own tool to craft your 'build in public' posts demonstrates its value instantly, turning your devlog into a live product demo.
Professional writers are fiercely protective of their workflows. By publicly sharing your design decisions and focus on specific niches (like SEO writing or academic research), you attract these power users who will gladly pay for a tool that saves them hours.
Perfecting AI outputs requires endless testing. Share your prompt iterations publicly and ask your audience for critiques. This community-driven QA helps you build a far superior product than testing in isolation.
The biggest risk for AI writing tools is that the underlying models become cheaper and commoditized. By building a strong personal brand and a loyal community through public building, you create a moat that protects you even if your core tech is replicated.
We built the exact tools you need to share your journey without wasting hours on marketing.
Specific, concrete updates that actually drive engagement in this niche.
The most effective marketing for a writing tool. Share the messy bullet points you started with, and the polished, perfectly formatted article your tool generated. Visual proof is undeniable.
Share your exact token usage and API costs versus your MRR. Discussing how you switched from GPT-4 to Claude 3.5 Sonnet to save 40% on server costs is top-tier indie hacker content.
Writers hate distractions. Share how you designed a distraction-free editor or implemented specific keyboard shortcuts. Discussing the philosophy of 'flow state' resonates deeply with your target market.
This is a massive concern for writers. Openly discuss your stance on AI detectors and the features you are building (like citation generators) to ensure your users' content remains authentic and safe.
Should you charge per word, per month, or offer a one-time lifetime deal? Share your thought process publicly and ask your early adopters what pricing model feels the most fair to them.
Document exactly how you got your first paying users. Did you do cold outreach to agencies? Did a viral Twitter thread drive traffic? Share the conversion data transparently.
The platform to host your long-form essays about the future of writing, document your technical architecture, and seamlessly cross-post to your audience on Twitter and LinkedIn.
The core engines of modern writing tools. Sharing your prompt engineering strategies and model comparisons guarantees high engagement from other AI founders.
The primary platforms where writers and marketers hang out. Distributing your 'dogfooded' content here is essential for top-of-funnel growth.
Crucial communities for getting early feedback. Cross-posting your technical updates here helps you find early adopters willing to test your beta.
Many solo founders have successfully built hyper-niche AI writing tools (e.g., specific for LinkedIn carousels or real estate listings). By sharing their prompt engineering and MRR publicly, they rapidly validate and monetize their niches.
While technically a scheduling tool, Typefully incorporates significant writing and formatting features. Tony's radical transparency regarding MRR and UI iteration built a massive, loyal audience of creators.
Founders building specialized Markdown editors or novel-writing software often build in public, sharing their philosophy on deep work and formatting to attract dedicated, paying authors.
Create your BuildInProcess profile. Write a post stating exactly who you are building for. Not 'everyone who writes,' but 'B2B SaaS copywriters who need programmatic SEO briefs.'
Before the UI is polished, post a screen recording of the terminal or a basic Vercel app generating high-quality text based on your custom prompts. Prove the logic works.
Write a long-form update entirely generated (and edited) using your own tool. Add a disclaimer at the bottom explaining how the tool assisted you.
Share a hilarious or frustrating time your AI completely hallucinated or failed to follow instructions, and exactly how you tweaked the system prompt to fix it.
Offer 50 lifetime access deals to your public audience to fund early development and secure highly motivated beta testers who will provide essential feedback.
Yes, for generic tools. But there is endless opportunity in hyper-specific workflows. Building in public helps you discover those specific workflows by talking directly to frustrated users.
Your moat is your UX, your specific integration into a user's workflow, and your personal brand. Building in public strengthens that personal brand, making users loyal to you, not just the API.
It's a balance. You can share the structure or the methodology of your prompts without giving away the exact proprietary text that generates your best outputs.
This is a common struggle. You must optimize your token usage and structure your pricing tiers carefully. Sharing this operational challenge publicly is highly engaging content for other founders.
Writers appreciate good writing. BuildInProcess provides a dedicated, professional environment for you to publish long-form essays demonstrating your product's capabilities, while handling the distribution for you.
