Released September 7, 2026
v1.8.6 makes long Brainstorm runs recoverable.
This maintenance release handles provider limits deliberately, restores ChatGPT login-page detection, and clears high-risk development dependency alerts.
Retry, Skip, or Cancel
Brainstorm pauses on limits, bridge timeouts, and structured provider errors. Skip uses a safe placeholder and never relays raw error text.
Graph v4 boundary
Older snapshots cannot silently adopt the new recovery semantics, and reserved turns clean up safely after retry or cancellation.
ChatGPT adapter v7
The redesigned login form is recognized without widening the provider's URL or permission boundary.
Dependency hardening
Four High Dependabot alerts were resolved; full and production audits reported no known vulnerabilities at release time.
Choose the conversation shape
Six presets. More than six answers.
Compare quickly, challenge an argument, build software plans, or spend a full session turning many perspectives into a decision.
Free
Selected providers answer in parallel for fast comparison and image prompts.
Debate
Pro, con, judge, and synthesis roles stress-test a decision or argument.
Consult
Two independent answers feed a review and a final recommendation.
Coding
Specification, reviews, implementation passes, tests, acceptance, and final output.
Roundtable
Four seats carry same-session history through five adversarial rounds.
Brainstorm
Rotating lenses move from framing and divergence to a decision-ready portfolio.
Brainstorm is intentionally substantial: keep all four sessions signed in and allow about 45–90 minutes. Preflight identifies an unavailable role instead of silently replacing it.
Local-first by design
Your sessions stay yours.
The app coordinates real provider pages while keeping its own state on your computer. It adds workflow, not another conversation cloud.
- 1
Sign in directly
Each provider runs in a separate local WebView profile. The app never asks for your password.
- 2
Choose a workflow
Select parallel targets or assign structured roles; unavailable providers are surfaced before a serial run.
- 3
Review one transcript
Read chronological results, inspect the live provider when needed, then continue or start a clean conversation.
Two editions, one idea
Pick the workspace that fits.
Both editions use your signed-in web sessions without API keys. The difference is how much workflow and local tooling you want around them.
| Feature | Desktop | Browser extension |
|---|---|---|
| Best for | Dedicated workflows and local continuity | Lightweight work inside Chrome |
| Workspace | Tauri app with isolated provider profiles | Side Panel plus your existing tabs |
| Local tools | Sessions, snapshots/replay, diagnostics, text files | Browser-native, compact controls |
| Shared foundation | Four real web sessions · zero API keys | Real provider tabs · zero API keys |
A narrow trust boundary
No API keys. No telemetry. No hidden relay.
Your prompts go to the providers you select. The app does not add an account server or analytics layer between you and them.
Provider webviews receive zero Tauri permissions
Cookies and provider profiles remain in local app data, isolated per provider.
Only the bundled local control pane can call app commands.
Adapter updates are schema-validated JSON and cannot expand bundled URL scopes.
Snapshots are opt-in, local, and use one of four frozen privacy tiers.
Diagnostics exclude page text, input values, cookies, storage, queries, and fragments.
Exports, debug bundles, and share actions require an explicit user action.
Honest boundaries
Automation follows changing websites.
Evidence is reported as evidence—not as a promise that every provider, account, or platform path works today.
Provider changes
A DOM or login-flow change can temporarily break automatic input, send, or completion detection until an adapter update ships.
Account rules remain
Subscriptions, quotas, regional rules, and challenges still apply. Claude requires login; Gemini and Grok blocks need user action.
Platform evidence differs
Windows launch is verified, macOS Apple Silicon is partially verified, and Linux packaging is currently CI-only.
v1.8.6 live gates
A full live 48-contribution recovery run and all live login/challenge paths were not manually reverified for this release.
Frozen product scope
No fifth provider, marketplace, graph editor, embedded terminal agent, telemetry, self-updater, or new snapshot schema is planned.
Read the evidence
