Common Questions About Switching
The free tier is genuinely useful, and $20/mo for Plus is less than our $29/mo. The hidden cost is time: prompting, context setup, copy-paste workflow. If you're doing occasional posts and enjoy the prompting process, ChatGPT works fine. If you want to generate LinkedIn content in seconds with persistent voice, that's our value proposition.
True—and that versatility is powerful. Research, coding, writing, analysis, all in one tool. For LinkedIn specifically, that generality means no LinkedIn-optimized features, no persistent voice, no direct publishing. Some people prefer one powerful tool for everything. Some prefer specialized tools that do one thing well. Both valid approaches.
Custom instructions help, and custom GPTs can store more context. They're good workarounds. Limitations: context still resets in long conversations, you can't upload 50 writing samples easily, no knowledge base grounding with citations. If custom GPTs work for you, stick with them. If you hit limitations, that's when specialized tools help.
Absolutely—image generation, code execution, web browsing, plugins, massive knowledge base. We can't compete on breadth. We compete on depth for one use case: LinkedIn content that sounds like you with knowledge grounding. If you need a Swiss Army knife, ChatGPT. If you need a specialized LinkedIn content tool, us.

If you want speed and consistency, Tonemark is more optimized.
Almost everything except LinkedIn-specific workflow. ChatGPT: image generation, code execution, web browsing, plugins, broader knowledge, free tier, versatility. We can't match ChatGPT's breadth. Our advantage is narrow: persistent voice learning, knowledge grounding with citations, LinkedIn-optimized output. Generalist vs specialist.
Custom instructions and custom GPTs help, but they're workarounds. Context limits mean you can't upload many writing samples. Long conversations lose early context. ChatGPT approximates your style from instructions; Tonemark learns from your actual writing samples and persists permanently. Different depth of personalization.
Time and workflow. ChatGPT Plus requires: open ChatGPT, write prompt, manage context, copy output, paste to LinkedIn. Tonemark: click generate, review, publish. At 12 posts/month, workflow savings add up. Plus persistent voice and knowledge grounding. Whether that's worth $9/mo extra depends on how you value your time.
Yes, common pattern. ChatGPT for: brainstorming topics, research, one-off tasks, image generation. Tonemark for: final LinkedIn content in your voice with knowledge grounding. Some founders use ChatGPT to explore ideas, then Tonemark to produce polished posts. Tools complement each other.
