Chain multiple LLM free tiers on one project via a shared progress file
Problem
Hobbyist developers bounce between Claude, Gemini, and ChatGPT free tiers to avoid paying for one subscription, but each switch means manually re-explaining the project context. Comments point to a couple of obscure GitHub routers, but nothing polished exists that handles the handoff: what's done, what decisions were made, what's next.
Opportunity
A desktop tool that maintains a canonical, model-agnostic project state file (progress log + decisions + file manifest), and automatically routes the next prompt to whichever free-tier model still has quota left — Claude → Gemini → ChatGPT rotation without context loss.
Market analysis
The target user is defined by unwillingness to pay, which caps the business at zero by construction. The underlying need (seamless model switching with preserved context) is already served by free, open-source desktop apps like Msty and LibreChat that unify multiple providers in one interface with shared conversation history. What remains open is only the automatic quota-aware routing, a thin layer whose value evaporates the moment a user's usage justifies any paid tier.
Market · Hobbyist developers and students on free tiers; vocal on Reddit but monetization-resistant by definition.
Pricing · No realistic price anchor: the audience's whole premise is avoiding ~$20/month subscriptions, and comparable multi-provider clients are free and open-source.
Pros
- + The canonical progress-file format (decisions, manifest, next steps) has genuine value as a portable artifact.
- + Open-source desktop tooling in this space is fragmented, leaving room for a polished UX.
- + Quota-aware routing is a real mechanical annoyance that no major tool addresses head-on.
Cons
- − The user base self-selects for zero willingness to pay.
- − Msty and LibreChat already cover multi-provider chat with persistent context for free.
- − Automating free-tier usage patterns invites provider rate-limit and ToS enforcement against the tool itself.

There is a real idea hiding inside this one, but it is not the router. A canonical, model-agnostic project-state file (what is done, what was decided and why, what is next, which files matter) is the durable artifact: it outlives any single model, works across paid and free tiers alike, and solves the context handoff even for people who happily pay. The quota-chaining wrapper is the weakest possible framing of that asset, because it optimizes for users whose defining trait is refusing to spend $20 a month, and because automating free-tier abuse patterns puts the tool on a collision course with provider rate-limiting. Build the state file as an open format with a modest desktop editor and the rotation as an optional plugin, and you have something useful to every developer instead of a workaround for a niche that cannot fund it.
