50 questions about troubleshooting.

Three options: 1) Upgrade tier (instant + prorated billing); 2) Wait for the 1st when caps reset to zero; 3) Buy a one-time cap top-up (V2 feature, not live yet). The cap-reached banner shows your exact reset date.

Check the network tab in DevTools for the actual response. Common causes: 1) The file is over the size cap (you'll see 413); 2) the server is processing (especially for video / Whisper, can take 60-120s); 3) network hiccup, retry.

Check for: 1) Trailing whitespace (paste might add spaces); 2) Case sensitivity; 3) Wrong PDF (some PDFs have both owner + user passwords — make sure you have the user one); 4) Special characters that your keyboard rendered differently. If all fail, the PDF may be using non-standard encryption — email hello@apexkit.pro.

Each tool has its own per-call limit on top of your monthly cap. PDF tools: 10 MB on Free, 100 MB on Basic, 500 MB on Pro+. Video tools: up to 2 GB on Pro+. Whisper: hard 25 MB cap (OpenAI limit). Compress the input first or split it.

For Compress Image: pick the High Quality preset. For Upscale: 4× on small inputs (<300px) loses sharpness — drop to 2× or wait for AI upscale in V2. For PDF→JPG: pick Print Quality (3× scale).

Common with mixed-format inputs (combining different page sizes in PDF Merge). Check the output in a desktop reader — page-fit should be 'Fit to page'. If pages are genuinely cropped, please email hello@apexkit.pro with the source file.

In PDF Merge widget, drag the cards to reorder before clicking Merge. The output order matches the card order at click time. If reorder didn't stick, refresh and try again.

Single-image enhancement has limits — try a brighter source photo, clean background, eyes-open, head-on angle. True multi-photo LoRA (much better quality + flexibility) ships V2 month 4-6.

Happens on photos with low contrast between subject + background. Try: 1) better lighting on the original; 2) a Pro+ alternative model (V2); 3) manual edit in a free tool like Photopea.

Whisper makes mistakes on heavy accents, background music, or technical jargon. Set the language hint to your specific dialect (en-GB vs en-US can differ); for technical content, the Pro+ enhanced model handles jargon better.

Try: 1) Setting source language explicitly (vs auto-detect); 2) Adjusting formality; 3) Breaking long paragraphs into shorter chunks. For specialist domains (legal, medical, technical) consider a domain-tuned tool.

Check: 1) Email confirmation completed? Resend the confirmation email at /sign-in/reset if not. 2) Cookies enabled for apexkit.pro? 3) Password correct (use Google if you set up that way). 4) If 2FA, your TOTP code? Last resort: hello@apexkit.pro.

Check spam folder. After 5 minutes: try /sign-up/reset with the same email. If still nothing, the email may be on a blocklist — try a different email address or contact hello@apexkit.pro.

Reset links expire after 1 hour. Request a fresh one from /sign-in/reset. If repeated requests fail, the issue may be on Supabase's side — wait 10 minutes and retry.

Common cause: 3D-Secure verification timed out (browser issue). Retry. If still fails: contact your bank — some block 'foreign' (UK-based) SaaS charges by default; ask them to whitelist Apexkit Ltd / Stripe.

Email hello@apexkit.pro with the invoice numbers. We'll cancel + refund the duplicate immediately (Stripe's confirm + refund usually under 5 minutes).

Email hello@apexkit.pro with the last 4 digits of the card. We can identify the account + cancel + refund if it wasn't authorised by you. (Most often a roommate / partner used the card or someone clicked Subscribe by accident.)

Webhook from Stripe to Apexkit can take up to 60 seconds. If after 5 minutes the dashboard still shows the old tier, sign out + sign back in. If still wrong, email hello@apexkit.pro.

Cancellation stops auto-renew, but you keep the tier until the current period ends. The 'renewal charge' might be a payment-retry from a previous failed charge. Check Stripe Portal → Invoices for clarity. Refund if needed via hello@apexkit.pro.

Sometimes a model provider has an outage. Wait 5 minutes + retry. If consistent over 30 minutes, email hello@apexkit.pro with the tool name + browser + screenshot of any error. We respond within 1-2 hours.

Could be: 1) Browser cache (Cmd/Ctrl+Shift+R); 2) Tier rate limit (free tier sees ~5s delays on AI tools vs ~1s on Pro+); 3) Underlying API slowness — check OpenAI / Anthropic status pages; 4) Your ISP / VPN latency.

Hard refresh (Cmd/Ctrl+Shift+R). Disable adblockers temporarily to check. If still blank, check browser DevTools console for errors and email the screenshot to hello@apexkit.pro.

Files are in browser memory until you close the tab or clear them. Click the × on each card to drop them from memory. Browser-side tools never store anything server-side.

Popup blockers can block programmatic downloads. Try: 1) Right-click the link → 'Save As'; 2) Disable popup blocker temporarily; 3) If on Safari, downloads sometimes go to a folder instead of asking — check ~/Downloads.

The browser closed the blob URL too early. Refresh + retry. If consistent, email hello@apexkit.pro with the tool name + browser version.

Check the file extension matches the actual content (a file named .jpg might actually be HEIC). Open the file in Preview / Photos to confirm format. Convert via /tools/image/convert-image if needed first.

Check: 1) Bearer prefix in Authorization header? 2) Key copied without trailing whitespace? 3) Key still valid (not revoked)? 4) Pro+ tier? Free / Basic don't have API access. Regenerate at /app/settings → API access.

Per-minute throttle is 50 req/min/user. Slow down + retry with exponential backoff. Monthly cap is separate (returns 402 instead).

Dashboard shows yellow at 70%, red at 90%. Plan ahead: 1) Upgrade tier proactively; 2) Defer non-urgent uses to next month; 3) Use the per-tool 1-free-use to offset peak.

Delete-account triggers Stripe cancel-at-period-end. You'll still get billed for the active period (no refund issued automatically); after that, no further charges.

Should arrive within 30 minutes of clicking. If not, email hello@apexkit.pro — we can trigger manually.

Downgrades take effect at the next billing cycle, not immediately. You keep the higher tier's benefits until then.

AI tools are probabilistic — re-run with slightly different input often improves output. For deterministic tools (Compress, Convert) the issue is usually input-specific; email hello@apexkit.pro with the file.

/app/files lists everything you've uploaded. Auto-delete clock: 24h on Free, 7d on paid. Beyond that, files are gone. Tools that run browser-side never store files server-side.

Likely browser blocked the Blob download. Retry the generate button. If blank PDF actually downloads, check browser console for errors and email hello@apexkit.pro.

Browser-side compression of large PDFs is CPU-bound — can take 30-60 seconds. Try the 'Web' preset (smaller output). Server-side compression with stronger algorithms ships V2.

Expected if input had mixed page sizes. The output PDF preserves each page's original size (modern readers handle this fine). For uniform sizing, pre-process each input.

Common cause: heavy AI processing running in background. Wait for the spinner to complete. If buttons still unresponsive after 30s, refresh.

Could be: 1) Suspicious activity (multiple failed sign-ins triggered Supabase auto-lock — try password reset); 2) Payment failed (your tier dropped, not locked); 3) ToS violation (very rare — we'd email you first).

Check status.apexkit.pro (V2). Until then, email hello@apexkit.pro — we respond within 30 min during business hours, sooner on outages.

Apexkit doesn't delete originals — it only operates on the file you uploaded. Your local original is untouched. If a server-side tool's output didn't download, look at /app/files for the stored output (24h Free, 7d paid).

Citation depends on the model finding a clear source. For abstract / inferred answers it may not cite. Try rewording your question to be more specific to one section.

Major UI shifts get announced in the /changelog. If you can't find a specific feature, search the /faq or email hello@apexkit.pro.

Check spam folder. Add hello@apexkit.pro + noreply@apexkit.pro to contacts. Resend's deliverability is generally good; persistent issues usually indicate your email provider is over-aggressive.

Settings → Toggle 'Weekly digest' to off. Or click the unsubscribe link at the bottom of any digest email.

Browser memory limit. Try: 1) Close other tabs; 2) Use a fresh window; 3) Compress / split the file first; 4) Use desktop Chrome (more memory headroom than mobile).

Could be: 1) Network issue (refresh); 2) Auth session expired (sign in again); 3) Browser cache issue (hard refresh: Cmd/Ctrl+Shift+R).

Browser cookie issue. Try: 1) Clear apexkit.pro cookies; 2) Use a different browser; 3) Disable browser extensions temporarily. If persistent: hello@apexkit.pro.

Stripe Tax determines VAT from billing country. If your country / status changed, update in Stripe Portal → Billing details. For UK B2B, enter VAT number for 0% reverse charge. Past invoices can't be retroactively VAT-corrected (Stripe limitation).

Not directly via UI — email hello@apexkit.pro with both account emails. We can transfer subscription history + delete the redundant account on request.
