Independent browser extension
SessionTrim is an independent browser extension that fixes thread slowdown first, then adds local-first workflow tools for power users.
It starts by reducing UI drag in long threads, then layers in private tools for prompts, export, folders, tags, privacy, and focus without extra account friction.
No official OpenAI affiliation. Built for Firefox and Chrome users who live in long threads.
What is SessionTrim?
SessionTrim keeps long ChatGPT threads fast by reducing UI drag, then adds a cleaner local workspace for prompts, exports, folders, tags, privacy, and focus. It is independent, local-first, and built for ChatGPT in Firefox and Chrome.
The problem
Dense sessions build up motion, layout churn, and context weight until ordinary work starts to feel unreliable.
Many add-ons win on feature count but add even more panels, prompts, and dashboard noise to an already busy surface.
People want export, saved prompts, and organization without vague permissions, cloud surprises, or misleading branding.
The solution
Kill heavy motion, reduce long-thread drag, and make dense sessions feel stable again before piling on extra tooling.
Prompt library, export, folders, tags, search, privacy tools, and focus mode all stay understandable because they live in browser storage.
Core stays free forever. Pro unlocks the heavier organization and workspace tools only if they actually become part of your daily flow.
