Two years ago I would have recommended a different stack. The tools were different, the free tiers were worse, and Claude wasn’t a primary recommendation for anything.
Today the calculus has shifted. The free tier gap between top models has narrowed, and the most important thing about an AI stack — persistent context across sessions — is now free in Claude Projects.
If I were starting from zero today, no paid subscriptions, just the free tiers: here’s exactly what I’d open every morning.
Primary Assistant: Claude (Free Tier)
Claude’s free tier runs Claude Sonnet — strong enough for most professional tasks: drafting, analysis, research synthesis, document review, code help.
The feature that makes it the primary recommendation: Projects. Persistent workspaces with shared context that carry across sessions. Set up a project with a context document describing your role and recurring tasks. Every session in that project starts from that baseline. The closest thing to a free AI assistant that actually knows you across sessions.
No other free-tier model offers this. It’s not a minor feature — it’s the difference between an AI tool and an AI system.
Research: Perplexity (Free Tier)
Perplexity synthesizes from live web results and links every claim to a source you can verify. This makes it categorically more useful than a general model for research tasks where source quality matters.
Use it for initial orientation on unfamiliar topics and for finding primary sources. Don’t use it as your final source — use it as the first step in building a verified source library. Academic mode gives better source quality for research-heavy workflows.
Code and Technical Tasks: Claude + GitHub Copilot (Free)
GitHub Copilot’s free tier covers 2,000 code completions per month — sufficient for developers who use it selectively. For VS Code users, the lowest-friction path to AI-assisted coding without payment.
For non-developers who occasionally write or modify code: Claude handles it in natural conversation. Paste your code, describe the problem, ask for a fix with explanation. The explanations are detailed enough to understand what changed and why — useful for building understanding, not just getting answers.
Meeting Transcription: Otter.ai (Free Tier)
300 minutes per month, real-time transcription, automatic speaker identification, searchable archive.
Workflow: transcribe the meeting, paste the transcript into Claude, ask it to extract decisions, action items, and open questions. Five minutes of post-meeting work produces cleaner output than most manual notes. One caveat: verify critical quotes before relying on them — accuracy drops on accented speech, technical vocabulary, and poor audio quality.
Image Generation: DALL-E (via ChatGPT Free) + Ideogram
ChatGPT’s free tier includes limited DALL-E generation. Ideogram’s free tier has better text rendering in images — useful for graphics that include readable text: diagrams, cover images, social graphics.
For heavy image generation use, neither free tier holds up and a paid plan becomes necessary faster than you’d expect.
The Honest Limitation
Free tiers are customer acquisition tools. The limits are calibrated to create upgrade pressure as usage grows.
This stack works for deliberate, focused use — specific tasks, defined sessions, not AI running continuously. If usage is light to moderate and purposeful, free tiers cover most needs indefinitely.
If AI tools become central to your daily workflow, unlimited access typically justifies the cost of a single paid subscription within the first month.
Start free. Use deliberately. Upgrade when the limits are the constraint, not your habits.
